first, let's break the equation down.
y=7x-4
-4 represents your staring coordinate, or your y-intercept. This is because -4 does not have an x after so you know it is equal to your y value. So you start at (0,-4)
Now all you need to do is the y=7x part.
The 7x represents your slope.
Slope is equal to rise/run or y/x.
So for each coordinate, you go up 7 and to the right 1.
(0,-4)
(1,3)
(2,10)
I hope this helps!
What is the slope of the line?
hurryyyy
Answer:
slope = 3
Step-by-step explanation:
if each square is equal to 1
The slope has to be 3.
you can see it, because between those 2 point you can count 3 spaces in y-vertex, and 1 space in x-vertex
what that means is that we will move 3 steps up (or down) for each 1 space in x-vertex.
you can see it just right there on the graph
a 3 inch radius circle is drawn inside a 7 in radius Circle if you throw a dart at the circles what is the probability you land inside the smaller circles
Answer:0.82
Step-by-step explanation:
The first step is to determine the areas of the inner and the bigger circles.
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Considering the inner circle,
diameter = 148.4 cm
Radius = 3 inches
Area = 3.14 × 3² = 28.26 inches²
Considering the bigger circle,
Radius = 7 inches
Area = 3.14 × 7² = 153.86 inches²
The area between the bigger and inner circles is
153.86 - 28.26 = 125.6 inches²
Probability = number of favourable outcome/number of total outcome.
the probability you land inside the bigger circle but outside smaller circle is
125.6/153.86 = 0.82
A store sells watches for $69.99 each and watch batteries for $9.50 each. Justin is buying 2 watches and x number of watch batteries. Which equation can be used to find y, the total price Justin must pay in dollars?
A y = 139.98x + 9.50x
B y = 69.99x + 9.50
C y = 9.50x + 69.99
D y = 9.50x + 139.98
Answer:
D. y= 9.50x + 139.98
Step-by-step explanation:
69.99 x 2 = 139,98

The sum of two numbers is 57 and the difference is 7. What are the numbers?
Answer:
32 and 25
Step-by-step explanation:
Which of the following correctly isolates the constant for the polynomial: x2 – 12x + 27
A. x^2 – 12x = 27
B. x^2 - 12x = 36
C. x^2 - 12x = -27
D. x^2 + 27 = 12x
Answer:
x^2 - 12x = -27
Step-by-step explanation:
Here, we want to isolate the constant for the polynomial
To do this, we start by setting the expression to zero
Afterwards, we can bring the constant term over the equal to sign, giving a change in sign value
Mathematically, we have this as;
x^2 - 12x + 27 = 0
x^2 - 12x = -27

which expression is equivalent to the problem shown?
A population of 6000 bacteria is growing at a rate of 6% each day. Write 2 an equation that expresses the number of bacteria at time x.
A. y = 6000(.06)×
B. y = 6000(1.06)×
C. y = 6000(.94)×
Answer: B. y = 6000(1.06)×
Step-by-step explanation: If it is growing at six percent (0.06) each day then you must also account for the amount that is already there (1).
Matt bought notebooks at the store for $1.07 each. He spent $3.21 on the notebooks. Let x represent the number of notebooks Matt bought. Use the equation 1.07x = 3.21 to find the number of notebooks he bought.
A salesperson receives a base salary of $35,000 and a commission of 10% of the total sales for the year. If a salesperson sells $250,000 worth of merchandise, what is her total income for the year, including her base salary?
Answer:
$60,000
Step-by-step explanation:
Given data
Base salary=$35000
commssion= 10%
Sales= $250,000
Let us find the commission
=10/100* 250,000
=0.1*250,000
=25000
Hence the total income is
=25000+35000
=$60,000

Find x in the following ,giving reasons
Answer:
x = 22.5
Step-by-step explanation:
→ Remember how many degrees the point to a radius is
90°
→ Set up an equation
x + 3x = 90
→ Simplify
4x = 90
→ Divide both sides by 4
x = 22.5
What is the next term of the geometric sequence 5, 20,80
Answer:
a₄ = 320
Step-by-step explanation:
To obtain a term in a geometric sequence , multiply the previous term by the common ratio r
r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{20}{5}[/tex] = 4 , then
a₄ = 4 × a₃ = 4 × 80 = 320

Mrs. Ortiz measured the outside temperature at noon as -2°F. Later that
day, she measured the temperature as -5°F. Write an inequality that
correctly compares -2 and -5. Then explain the meaning of the inequality
for the situation. 6.NS.7, 6.NS.7b
Answer:
-2°F>-5°F
Step-by-step explanation:
-2°F is greater than -5°F
This also means the first time Mrs. Ortiz measured the outside tempurature it was hotter than the second time she measured it.
