Answer: 3x^2+15x
Step-by-step explanation:
3x(x+5)
(x * x = x^2 and x * a number = a coefficent)
= 3x^2+15x
Correct answer is option C.(-3,-5) and (3,7)
<u>Step-by-step explanation:</u>
Let us take the value of y from equation y=2x+1 and plugin to the equation y=x2+2x-8
so
2x+1=x2+2x-8
taking constants on left hand side and literals on the right hand side
1+8=x2+2x-2x
9=x2
this implies that value of x=+3,-3
now plug in the value of x in the equation y=2x+1
when x=+3
y=2*3+1 = 7
so (3,7)
when x=-3
y=2*(-3)+1 = -5
so (3,-5)
hence the answer is (-3,-5) and (3,7)
Answer:
Yes, the quantities are proportional.
Step-by-step explanation:
To determine whether they were proportional or not, I compared the ratio of grams of sugar to servings in each pair of data points. 4/2, 6/3, 8/4, and 10/5 were the four points. All of them can be simplified to 2/1, which tells us that each serving of sugar is 2 grams, no matter how many servings are counted. This means that the amount of sugar grows in direct proportion to the number of servings.
