Answer:
y = (ax)2
y = 2ax
divide both sides by 2a to make x the subject of the formula.
y/2a = 2ax/2a
x = y/ 2a

Find the equation of the line shown in the picture.
Answer:
y = x + 6
Answer:
firstly you have to find the slope of the line.
Step-by-step explanation:
for thus, use the number which is on the coordinate system like x and y. the slope is (10-6)/(4-0) =1 so m=1
the equation should be on this form y-y1=m"(x-x1)
then put the value of y and x from equation.
when the x is 4 the y have to be 10
y-10=1*(x-4)
finally the equation is y=x+6

1. Find the value of x in the figure below if GH is parallel to JK.
A. 4 units
B. 9.8 units
C. 6.7 units
D. 5 units
Answer:
D. 5 units
Step-by-step explanation:
The parallel segments divide the slant segments proportionally:
7.5/10.5 = x/7
x = 7(7.5/10.5) = 5 . . . . . multiply by 7
The value of x is 5 units.
_____
If you want to use corresponding sides of similar triangles, you get the same result. ΔIGH ~ ΔIJK
IJ/IG = IK/IH
7/(7+10.5) = x/(x+7.5) . . . . substitute shown values
7(x +7.5) = 17.5x . . . . . . . cross multiply
7(7.5) = 10.5x . . . . . . . . . subtract 7x
x = 7(7.5/10.5) = 5 . . . . . divide by the coefficient of x

can any equation in point-slope form also be written in slope-intercept form?
Answer:
Yes
Step-by-step explanation:
The way the equation is written in point-slope form is:
[tex]y-y1=m(x-x1)[/tex]
The way we write an equation in slope-intercept form is:
[tex]y=mx+b[/tex]
We can change point-slope form to slope-intercept form by first distributing the m and then adding y1 to both sides of the equation. When we do this we will get:
[tex]y=mx-(m*x+y1)[/tex] where [tex](m*x+y1) = b[/tex]
which is now in slope intercept form.

Group of answer choices
93%
10%
7%
17%
The probability that the bill will be less than $100 is 7%
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\x=raw\ score, \sigma=standard\ deviation, \mu=mean\\\\\\Given\ that\ \sigma=32,\mu=147,hence:\\\\For\ x<100:\\\\z=\frac{100-147}{32}=-1.47[/tex]
From the normal distribution table, P(x < 100) = P(z < -1.47) = 0.0708 = 7.08%
The probability that the bill will be less than $100 is 7%

What is the value of x?
Answer:
the value of x is 6 i believe
Step-by-step explanation:
What is value of x? Value of x is used to consider unknown value. The letter “x” is commonly used in algebra to indicate an unknown value. It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable. But its value may be determined if we try! A variable need not be “x,” but might be “y,” "w," or any other letter, name, or symbol.
A power company calculates a person's monthly bill from the number of
kilowatt-hours (kWh), x, used.
The function b(x) = {
0.15x, x < or equal 200
0.10 (x - 200) + 30, x > 200
determines
the bill.
How much is the bill for a person who uses 300 kWh in a month?
A. $45
B. $40
Ο Ο Ο Ο
C. $60
D. $55
please help
Answer:
B. 40
Step-by-step explanation:
if x=300, it means x>200, then b(x)=0.1(x-200)+30; ⇔ b(x)=0.1*100+30= 40 [USD].
The bill for a person who uses 300 kWh in a month is $40.
Option B is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
For a person who uses 300 kWh in a month, we need to use the second part of the function:
b(x) = 0.10(x - 200) + 30, x > 200
Substituting x = 300, we get:
b(300) = 0.10(300 - 200) + 30
b(300) = 0.10(100) + 30
b(300) = 10 + 30
b(300) = 40
Therefore,
The bill for a person who uses 300 kWh in a month is $40.

The surface area of the triangular prism ramp is: 1,020 ft².
Surface Area of Triangular PrismSurface area = 1/2(base area × height)
The triangular prism has the following dimensions:
base area = 20 × 12 = 240 ft²
height = 8.5 ft
Plug the values into the formula:
Surface area = 1/2(240 × 8.5)
