What is the equation of the line that has a y-intercept of -7 and is perpendicular to the line represented by the equation below

? 8x 7y=19

8x + 7y = 19
- 8x
7y = 19 - 8x
÷ 7
y = 2 5/7 - 8/7x
So if that line is perpendicular to the line you're looking for, then the gradient (x value/slope) is the negative reciprocal to the gradient you're looking for, which would then be 7/8. You are told it has a y intercept of -7, so your final answer is:
y = -7/8x - 7
Hope this helps!

Use the multiplication property of exponents to determine if each statement is true or false.
lisabon 2012 [21]
1)
LHS:
{a}^{4}  \times  {a}^{3}  \times a \\  =  {a}^{4 + 3 + 1}  \\  =  {a}^{7}
LHS = RHS. So, the statement is true

2)
LHS:
{5}^{2}  \times  {3}^{4}  \\  = 25 \times 81 \\  =  {5}^{2}  \times  {9}^{2}  \\  =   {45}^{2}
LHS not equal to RHS. So, the statement is false

3)
LHS:
{x}^{6}  \times  {x}^{0}  \times  {x}^{2}  \times  {x}^{3}  \\  =  {x}^{6 + 0 + 2 + 3}  \\  =  {x}^{11}
LHS = RHS. So, the statement is true.

4)
LHS:
7 {m}^{2}  \times 2m \times 4 {m}^{5}  \\  = (7 \times 2 \times 4) {m}^{2 + 1 + 5}  \\  = 56 {m}^{8}
LHS = RHS. So, the statement is true.

Ad libitum [116K]

Answer:

y = -0.07x2 + 3.07x

Step-by-step explanation:

For each plant we add, there is a decrease of 70 grams for all plants from the inicial value of 3 kg of beans.

So, for 2 plants, we have (3 - 0.07) * 2

For 3 plants, we have (3 - 2*0.07) * 3

For x plants, we have (3 - (x-1)*0.07) * x

So we can model the final result of the amount of beans 'y' with the equation:

y = (3 - (x-1)*0.07) * x

y = (3 - 0.07x + 0.07) * x

y = (3.07 - 0.07x) * x

y = -0.07x2 + 3.07x

(In this equation we have a = -0.07, b = 3.07 and c = 0)

galina1969 [7]

Answer:

C. x³+10x²−5x+5

E. 7x⁵+4x²

F. x+8

Step-by-step explanation:

The graph they described should look something like the one i drew below.

So all you have to do is look at the number with the highest exponent.

If the exponent is an odd number and the x is positive then that function will have an end behavior like the picture i posted.

x³ is good

-x³ is bad because of the negative sign

x² is bad because exponent is even

x⁷ is good

123x¹ is good
