(x−2) 2 +(x+8) 2 =10
Please Explain ASAP
Answer:
x= -0.5
Step-by-step explanation:
2x-4+2x+16=10
4x+12=10
4x=-2
x=-1/2
Step-by-step explanation:
(x-2) 2 +(x+8) 2 = 10
x-2 + 2× x 2×8 + 2 = 10
x - 2 + 2x + 16 + 2 = 10
x + 2x + 16 - 2 + 2 = 10
3x + 16 = 10
3x = 10-16
3x = -6
3x÷3x = 6 ÷ 3
x = -2
how many questions I have to ask?
Answer:
p is 16
Step-by-step explanation:
[tex]p \: \alpha {(q + 2)}^{2} [/tex]
introduce a constant on a right hand side:
[tex]p = k {(q + 2)}^{2} - - - eqn \: (a)[/tex]
[ when q is 1, also p is 1 ]
[tex]1 = k(1 + 2) {}^{2} \\ 1 = 9k \\ k = \frac{1}{9} [/tex]
substitute for k in eqn (a):
[tex]p = \frac{1}{9} (q + 2) {}^{2} [/tex]
so, when q is 10:
[tex]p = \frac{1}{9} (10 + 2) {}^{2} \\ \\ p = \frac{1}{9} (144) \\ \\ p = 16[/tex]
the length of a board is 2 5/8 feet long. If 5/6 of a foot is trimmed off, find the new length
Answer:
New length is 3 3/20 ft.
Step-by-step explanation:
The total board is 2 5/8 feet long. And since 5/6 of a foot is trimmed off, that means each piece of wood is 5/6 feet.
We can now set up an equation like this ---> 5/6 ⋅ x = 2 5/8
Now we're going to simplify ---> 5/6 ⋅ x = 2 5/8
5/6 ⋅ x = 21/8
(multiply both sides by 6)
5x = 63/4
(divide both sides by 5)
x = 63/20
x= 3.15
So, the new length is 3.15 feet long, or 3 3/20 in mixed fraction.

[tex]\frac{3}{2}[/tex]
Step-by-step explanation:
The scale factor is the ratio of corresponding sides, B to A , then
scale factor = [tex]\frac{9}{6}[/tex] = [tex]\frac{3}{2}[/tex] ( = 1.5 )
please guys help me i dont understand
Answer:
140
Step-by-step explanation:
For every 2 hours, the number goes up 140 miles.
Note: it does not ask for the MPH, it asks for Rate of Change.
Rate of Change is asking for the difference between numbers from one circumstance to the next. For example, in this question, as the table goes up 2 hours in each section, so does miles traveled. Calculate the difference in miles driven for each section to concur that the Rate of Change is 140.
Answer:
70 mph
Step-by-step explanation:
The rate of change is measured as the ratio of the difference between any 2 ordered pairs from the table
Using (4, 280 ) and (6, 420 ) , then
rate of change = [tex]\frac{420-280}{6-4}[/tex] = [tex]\frac{140}{2}[/tex] = 70 mph
Explain what is the difference between radius
and circumference
Answer:
The circumference is the perimeter, specifically the perimeter of a circle. It can be solved by using the following formula:
C = 2πr
C stands for circumference.
π stands for pi, or 3.14 (rounded).
r stands for radius.
The radius is the distance from the center point of the circle to any point on the circle. It is denoted by the variable, r, as stated above. It is 1/2 of the diameter.
Answer:
the radius is the line from center to perimeter and circumference is the enclosed boundary
Step-by-step explanation:
radius- is any of the line segments from a circle or spheres center to its perimeter
circumference- the enclosed boundary a curved geometric figure, especially a circle
Pls help I need it I’m really confused
The equations are alike because all of their variables are equivalent to 6. Another similarity is that they are all one-step equations, meaning they can be solved with just one operation.
[tex]4a=24\\a=6[/tex]
[tex]c-1.2=4.8\\c=6[/tex]
[tex].5b=3\\b=6[/tex]
[tex]d + 5.5=11.5\\d=6[/tex]
These equations are different because require different operations to find their variables. Their terms, excluding the variable, also have differnt values.

Answer:Option D
Step-by-step explanation:
A toaster that sells for $62 is on sale for 35% off. Identify the sale price.
Answer:
40.3
Step-by-step explanation:
62×(1-35%)= 40.3
100% - 35% = 65%
The toasters sale price is 65% of the original price:
$62 x 0.65 = $40.30
Sale price = $40.30

Answer:
x =24
Step-by-step explanation:
3(x + 4) = 4(x -3)
3x + 12 = 4x -12
add 12 to both side
3x + 24 = 4x
subtract 3x
24 = x
. Define opposite numbers.
Answer:
Opposite numbers are numbers that, when placed on a number line, are the exact same distance away from the 0, but on opposite sides, or in opposite directions. They look the same except for their signs.

What is 687 divided by 14
Answer:
49.0(714285) or 49 and remain 1
Step-by-step explanation
687/14 = 49
49*14 = 686
687 - 686 = 1
49 and remain 1 (Remain Method)
1/14 = .0714285714285714285.... => .0(714285)
Now add 49 to the result, we get 49.0(714285)

HELP ASAP PLS
A spinner is divided in to fourths and is labeled 1-4. John spins the spinner and tosses a coin. What is the
probability of spinning a 1 and flipping heads?
Answer:
1/8 or 12.5% probability
Step-by-step explanation:
Compound probability is what you would want to use here which is the probability of the first event multiplied by the second event.
So, if 1/4 is the probability of spinning a 1 on the spinner and 1/2 is the probability of flipping heads, you would multiply 1/4 • 1/2 to get 1/8, or 12.5%
Hope this helped!

Bottom half starting from “Given: XY = x + 6”
Problem 22
Answer: x = 7-----------------------
Explanation:
Segments XY and YZ add up to segment XZ
XY + YZ = XZ
(x+6) + (3x+1) = 5x
4x+7 = 5x
7 = 5x-4x
7 = x
x = 7
===============================================================
Problem 23
Answer: XY = 13-----------------------
Explanation:
We'll use the result in the previous problem to find that,
XY = x+6
XY = 7+6
XY = 13
===============================================================
Problem 24
Answer: YZ = 22-----------------------
Explanation:
Similar to problem 23, we'll use the value of x = 7 to find that,
YZ = 3x+1
YZ = 3*7+1
YZ = 21+1
YZ = 22
===============================================================
Problem 25
Answer: XZ = 35-----------------------
Explanation:
We have two options. We could add the results of the last two problems
XZ = XY + YZ = 13+22 = 35
Or we could compute XZ directly like so
XZ = 5x = 5*7 = 35
Either way, we get the same result. The fact we get the same value both times helps confirm we have the correct x value and the correct lengths of XY and YZ.
Answer:
x = 7XY = 13YZ = 22XZ = 35Concept:
Here, we need to know the idea of the segment addition postulate.
The segment addition postulate states the given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC. In another word, if 3 points A, B, and C are collinear and B is between A and C, then AB + BC = AC.
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
Given information
XY = x + 6
YZ = 3x + 1
XZ = 5x
Given expression deducted according to the segment addition postulate
XY +YZ = XZ
Substitute values into the expression
x + 6 + 3x + 1 = 5x
Combine like terms
4x + 7 = 5x
Subtract 4x on both sides
4x + 7 - 4x = 5x - 4x
x = 7
Find the value of XY
XY = x + 6 = (7) + 6 = 13
Find the value of YZ
YZ = 3x + 1 = 3 (7) + 1 = 22
Find the value of XZ
XZ = 5x = 5 (7) = 35
Check:
Left-hand side: XY + YZ = 13 + 22 = 35
Right-hand side: XZ = 35
35 = 35
Hope this helps!! :)

What is the scale factor from L to S
Answer:
-2
Step-by-step explanation:
Triangle S
Base = 2Height = 4Triangle L
Base = 4Height = 8For the base you must multiply 4 by -2 to get 2. Likewise for the height you must multiply 8 by -2 to get 4. Thus the scale factor from L to S is -2
