It looks like the parabola are going down, so  the coefficient should be negative,
B or C,
then we see that the parabola has x -intercepts (1,0) and (5,0)
these roots should be written as multiples 
x=1, so x-1=0
and 
x=5, so x-5=0,
so (x-1)(x-5) and negative first coefficient -2 at the same time. 
We can see only in the 
B. <span>f(x) = –2(x – 5)(x – 1)</span>

Please help 7(-37 + k) = 26
Georgia [21]

Answer:

7(k−37)=26

  • Divide both sides by 7

k−37= 26/7

  • Add 37 to both sides

k= 26/7 +37

  • Simplify  26/7 +37 to 285/7

k= 285/7

A bag contains purple marbles and white marbles, 96 in total. The number of purple marbles is 6 less than 5 times the number of
love history [14]
<em /><em>PURPLE MARBLES=P
WHITE MARBLES=W

</em>First, write out an equation showing the number of purple marbles.
P=5W-6
Then, write out the main equation.
W+P=96
W+5W-6=96
Add 6 to both sides.
W+5W=102
6W=102
Divide both sides by 6
W=17
Now that we know there are 17 white marbles, we can go back to the equation about how many purple marbles there are. 
P=5W-6
Plug in the value for W, which is 17.
P=5(17)-6
P=85-6
P=79

To make sure your answer is correct, check your work by plugging in the values for P+W=96.
79+17=96
Answer: There are 79 purple marbles.
