Solve the following equation for y
24x - 8y = 72
I need help right now as fast as u can
Answer:
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
24*x-8*y-(72)=0

Pulling out like terms
1.1 Pull out like factors :
24x - 8y - 72 = 8 • (3x - y - 9)

Equation of a Straight Line
2.2 Solve 3x-y-9 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 3x-y-9 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 9/-1 so this line "cuts" the y axis at y=-9.00000
y-intercept = 9/-1 = -9.00000
Calculate the X-Intercept :
When y = 0 the value of x is 3/1 Our line therefore "cuts" the x axis at x= 3.00000
x-intercept = 9/3 = 3
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -9.000 and for x=2.000, the value of y is -3.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -3.000 - (-9.000) = 6.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 3
Geometric figure: Straight Line
Slope = 3
x-intercept = 9/3 = 3
y-intercept = 9/-1 = -9.00000

which graph shows all the values that satisfy 2/9x+ 3> 4 5/9
Answer:
The first option
Step-by-step explanation:
2/9 x + 3 > 4 5/9
2/9x > 4 5/9 - 3
2/9x > 14/9
x > 14/9 ÷ 2/9
x > 7
Mr.Chang has a class of 18 students. He can spend $21 on each student to buy math supplies for the year. He first buys all of his students calculators, which cost a total of 170.64. After buying the calculators, how much does he have left to spend on each student
Answer:
572557486637778886367828766664728274747447378328288273
Answer: $11.52 left for each student
Step-by-step explanation:
First, divide the total amount of money spent by the total amount of students. 170.64/18. You will get $9.48. So, that means that so far Mr. Chang has spent $9.48 on each student. Then, just subtract $9.48 from $21 (which is the total amount he is willing to spend on each student. You should get $11.52. So, Mr. Chang has $11.52 left to spend on each student. Hope this helps!

A cell phone plan charges $39.95 a month plus 15 cents per text message sent and 15 cents per text message received. Using s to represent the number of text messages sent in one month and r to represent the number of text messages received in one month, the following equation can be used to calculate the total monthly cost, c:
c = 39.95 + 0.15(s + r)
If it is known that the total monthly cost is $53.45 and 63 text messages were received, solve for s, the total number of text messages sent.
Answer:
c= 39.95 +0.15 (s + r) (take the 63 received and plug it in for r and 53.45 in for c then solve)
53.45= 39.95 +0.15 (s +63) (use the distributive property)
53.45 = 39.95 + 0.15s + 9.45 (combine like terms on the right side)
53.45 = 49.40 +0.15s (subtract 49.40 from both sides)
4.05 = 0.15s (divide both sides by 0.15 so isolate s)
s= 27 (how many text messages were sent)
Step-by-step explanation:
I hope this helps :)
Answer:
s=27

find the slope of the line passing through the given points
Answer:
-5/6
Step-by-step explanation:
Slope= y2-y1/x2-x1
Answer:
The slope is -5/6
Step-by-step explanation:
You can use the method rise over run and count how many squares it takes to go from the y coordinate 4 to the y coordinate -1, which is -5. You can then count how many squares you need to get from the point -3 to 3 which is 6. Or you can use the formula to find slope, (y2-y1)/(x2-x1) and plug in you numbers.
If you had a choice between investing $1,000 in a mutual fund that are 7.5% compound interest or a bond that earns simple interest at 7.5% which would you prefer and why
Answer:
mutual fund
Step-by-step explanation:
Step one:
given data
let say the investment plan will span for 5 years
so for mutual fund
P= $1000
r= 7.5%= 0.075
t= 5
compound interest
A= P(1+r)^t
substituting
[tex]A= 1000(1+0.075)^5\\\\A=1000(1.075)^5\\\\A=1000*1.436\\\\A=$1436\\\\[/tex]
$1436
so for bond
P= $1000
r= 7.5%= 0.075
t= 5
simple interest
A= P(1+rt)
substituting
[tex]A= 1000(1+0.075*5)\\\\A=1000(1+0.375)\\\\A=1000(1.375)\\\\A=1375\\\\[/tex]
A=$1375
$1375
I would go for mutual fund compounded interest because it offers extra
$61 (1436-1375) for the same investment capital
is a stockbroker. Earns % commission each week. Last week, sold $ worth of stocks. How much did make last week in commission? If averages that same amount each week, how much did make in commission in 2011?
Answer:
a. $583
b. $30,316
Step-by-step explanation:
a. Commission last week;
= 5,300 * 11%
= $583
b. Commission in 2011 assuming weekly earnings of $583.
= 583 * 52 weeks
= $30,316
How is the number in the square root called (number 4) how can I place that in a calculator
The 4 in the symbol is the index of the radical sign √.
Whether you can write this expression on a calculator depends on the calculator... If you have one with a CAS (that is, a "computer algebraic system"), chances are there is a built-in button for things like square roots and cube roots, and possibly roots of higher indices. If not, you can always express a radical expression using a fractional exponent, such as
[tex]\sqrt x\iff x^{\frac12}[/tex]
or
[tex]\sqrt[3]{x}\iff x^{\frac13}[/tex]
or
[tex]\sqrt[4]{x}\iff x^{\frac14}[/tex]
and so on. So the given expression could be typed in as (16*x^6*y^7)^(1/4), for instance.
I'm guessing you have to simplify the given expression. You could end up with
∜(16x ⁶y ⁷) = ∜(2⁴ x ⁴ x ² y ⁴ y ³)
… = 2xy ∜(x ² y ³)
(assuming x and y are positive)

Meghan ran 9/12 of a mile and skipped 8/12 of a mile how far around the track did meghan go in total. Use the benchmark fraction 1/2, 1, and 0 to help you estimate each answer before you solve
Answer:
Megan went a total distance of 1 5/12 miles
Step-by-step explanation:
Here, we want to calculate the total distance worked around the track
We are told that she ran 9/12 and skipped 8/12
The total distance around the track will be the sum of these two
Mathematically, that will be;
9/12 + 8/12
= 17/12 = 1 5/12

there are two food trucks for sale that would be perfect for your business. the blue food truck is in perfect condition, but 8,000 more than the green food truck. The green food truck is in need of repairs to make it fully functional. The two trucks together cost 172,000. How much does each food truck cost
Answer:
blue truck-$82000 green truck-$90000
Step-by-step explanation:
x+8000=y
x+y=172000
Solve for y
8y - 8 = 4x
Answer:y= 1/2x +1
Step-by-step explanation: This is your answer
Answer:
Step-by-step explanation:
8y - 8 = 4x
Add 8 to both sides
8y = 4x + 8
Divide both sides by 8
y = [tex]\frac{4x + 8}{8}[/tex]

Step-by-step explanation:
The middle school dance team had 2 separate car washes on Saturday to raise money for new uniforms. The Main Street location raised $50 more than the Back Street location. How much did the dance team raise at each location if they raised a total of $980?
Answer:
$465 at Back Street
$515 at Main Street
Step-by-step explanation:
980 (total) - 50 (the difference between the two) = 930
930/2 = 465 (back street)
465 + 50 (the difference) = 515 ( main street)
CHECK: 465 + 515 = 980

Graphs:The set of ordered pairings (display style [tex](x,y)[/tex]) of a function (display style [tex]f(x)=y[/tex]) in mathematics is known as the graph of that function. These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the typical case where "display style [tex]x[/tex]" and "display style [tex]f(x)[/tex]" are real values.Graph equations:Equations with graphs as the unknowns are known as graph equations in graph theory. The concept of isomorphism is one of the key issues in graph theory. Different graph equations may be used to express the aforementioned graphs.Therefore, the correct equation for the blue graph is [tex]g(x)=(x-4)^{2}[/tex].
