1/5 yard ------------------
7/10 yard
<span>The distance poles B and D= (1-1/5)=4/5 yard
</span>The distance poles B and E= BD+DE=4/5+7/10=(8+7)/10=15/10=3/2 yard
the answer is 3/2 yard (distance poles B and E)
Answer:
y = -5x + 90
Step-by-step explanation:
y = mx + b is slope intercept form
b is the y intercept, meaning that 90 is the y-intercept
m is the slope (rise over run), 20/4, 5/1, 5
y = -5x + 90
this wasnt the best explanation but I hope it helped
Answer:
x = -1/2
Step-by-step explanation:
multiply the -4 to all in parentheses
-4(3-2x) +2x =2x -8
-12+8x +2x =2x-8
isolate x by moving whole numbers to other side of equal sign and x to the other side
8x +2x -2x = -8+12
8x = -4
/8
divide by 8 to isolate x
x= -4/8
simplify
x= -1/2

Answer: g(x) = (-2/3)*x^2</h3>
============================================
Work Shown:
f(x) = x^2
g(x) = a*f(x) for some constant 'a' since g(x) is a scaled version of f(x).
The value of 'a' vertically stretches f(x) upward if a > 0
If 'a' is negative, then we have a reflection going on as shown in the diagram.
We want (x,y) = (3,-6) to be on the graph of g(x). This means g(3) = -6
If we plugged x = 3 into f(x), we get
f(x) = x^2
f(3) = 3^2
f(3) = 9
So,
g(x) = a*f(x)
g(3) = a*f(3) ... replace x with 3
g(3) = a*9 ... replace f(3) with 9 since f(3) = 9
-6 = a*9 ... replace g(3) with -6 since g(-3) = -6
9a = -6
a = -6/9
a = -2/3
Therefore, this means
g(x) = a*f(x)
g(x) = (-2/3)*f(x)
g(x) = (-2/3)*x^2
