Graph this function using intercepts Solve 10x+9y=-90
Alex17521 [72]

Answer:

Step-by-step explanation:

So first, lets solve for the intercepts.

Let’s start by finding the x intercept.

Plug in 0 for y.

10x+9(0)=-90

10x=-90

X=-9, so your first point on your line will be (-9,0).

Now the y intercept.

Plug in 0 for x.

10(0)+9y=-90

9y=-90

Y=-10, so your second point on your line will be (0,-10).

Use those points to create your line.

Expand the number 1120 into its corresponding exponential form. 25 · 5 · 7 52 · 8 22 · 53 · 7 2 · 5 · 7
Eduardwww [97]

Answer:

(A) 2^{5} * 5 * 7

Step-by-step explanation:

Your question formatting made it very complicated to understand the possible answers.  Please use some notation or the equation editor next time.

So, the exponential form a way to write a number using multiplications and powers.

Let's examine the various options (if I read them correctly)

(A) 2^{5} * 5 * 7 - YES!

2^{5} is 32, so 32 * 5 * 7 = 160 * 7 = 1120

(B) 5² · 8  - NO

= 25 * 8 = 200

(C) 2² * 5³ * 7 - NO

= 4 * 125 * 7 =500 * 7 = 3500

(D) 2 · 5 · 7 - NO

= 10 * 7 = 70
