Slope=5, goes through the point (2,7)..
Answer:
the y-intercept is 7
Step-by-step explanation:
hope it helps. i just looked at the ordered pair and took the number that's on the y axis
Answer:
y=5x-3
Step-by-step explanation:
Slope intercept form is y=mx+b and you know the slope so you can get y=5x+b
Then you are given a point, (2, 7), so you can plug that into the equation to find the y-intercept
7=5(2)+b
Then you just solve for b
7=10+b
-10
-3=b
So the final equation is y=5x-3

The diagram shows a track composed of a rectangle with a semicircle on each end. The area of the rectangle is 6,600 square meters. What is the perimeter of the track? Use 3.14 for pi
Answer:
The perimeter of the track is the two circumferences of the semicircles (when combined, they form one circle, so we can just find the circumference of the circle) added to the lengths of the rectangle (160 meters).
To find the circumference of the circle, we need to know the diameter.
Circumference of a circle: dπ or 2rπ, where d represents diameter and r represents radius
The diameter of the circle happens to be the same as the width of the rectangle. We know that the area of a rectangle is found by multiplying its length by its width. We know that the area is 14400 and that its length is 160.
Width: area divided by length
14400160=90
The diameter of the circle and the width of the rectangle is 90 meters.
Circumference:
90⋅π=90π→ If you are using an approximation such as 3.14 for π, multiply that by 90
Add 160⋅2 to the circumference since the lengths of the rectangle are also part of the perimeter.
160⋅2=320
90π+320

x = 6
you have to work out the problem and what ever you do to one side, you do to the other
Answer:
x=6
Step-by-step explanation:
2x+5=17
Subtract 5 from both sides;
2x+5-5=17-5
Simplify
2x=12
Divide both sides by 2;
2x/2=12/2
Simplify;
x=6

Step-by-step explanation:
the graph of h is the graph of f(x)=x^2 translated 4 units left and 7 units down. Write the function H in vertex form.
Answer:
f(x)=a(x - h)2 + k
Much like a linear function, k works like b in the slope-intercept formula. Like where add or subtract b would determine where the line crosses, in the linear, k determines the vertex of the parabola. If you're going to go up 2, then you need to add 2.
The h determines the movement horizontally. what you put in h determines if it moves left or right. To adjust this, you need to find the number to make the parentheses equal 0 when x equals -2 (because moving the vertex point to the left means subtraction/negatives):
x - h = 0
-2 - h = 0
-h = 2
h = -2
So the function ends up looking like:
f(x)=a(x - (-2))2 + 2
Subtracting a negative cancels the signs out to make a positive:
f(x)=a(x + 2)2 + 2
Step-by-step explanation:
The translated value of the function is h ( x ) = ( x + 4 )² - 7
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x²
we can obtain the function h(x) by first translating it 4 units to the left, which gives us f(x + 4), and then translating it 7 units down, which gives us f(x + 4) - 7. Therefore, the function h(x) can be written as:
h(x) = f(x + 4) - 7
To write this in vertex form, we need to complete the square. First, we have:
h(x) = f(x + 4) - 7
h(x) = (x + 4)² - 7
This is the vertex form of the equation for h(x). The vertex of the parabola is at the point (-4, -7), which is obtained by setting x + 4 = 0 in the equation above.
The value of the vertex is -7, which is obtained by subtracting 7 from the squared term.
Therefore, the vertex form of the equation for h(x) is:
h ( x ) = ( x + 4 )² - 7
Hence , the transformed function is h ( x ) = ( x + 4 )² - 7

2600, 3400, 5000, 7000
Step-by-step explanation:
This equation can be simplified to 200n + 1000. Now we can just plug in the amount of customers. 200 * 8 + 1000 = 2600. 200 * 12 + 1000 = 3400. 200 * 20 + 1000 = 5000, and 200 * 30 + 1000 = 7000.
