Answer:

if you divide both sides of -5x > 0 you get z > 0. This is incorrect because if you choose a value from the possible solutions such as z=6 and substitute it into the original equation you get -30 > 0, which is not true

Step-by-step explanation:

2 $x^{2}$ -16=0

+16 +16

2 $x^{2}$ =16

÷2 ÷2

$x^{2}$ = 8

$\sqrt{x^{2} }$ = $\sqrt{8}$

x= $\sqrt{8}$

-5 $x^{2}$ +9=0

-9 -9

-5 $x^{2}$ =-9

÷-5 ÷-5

$x^{2}$ =1.8

$\sqrt{x^{2} }$ = $\sqrt{1.8}$

x= $\sqrt{1.8}$

6 $x^{2}$ -15=27

+15 +15

6 $x^{2}$ =42

÷6 ÷6

$x^{2}$ =7

$\sqrt{x^{2} }$ = $\sqrt{7}$

x= $\sqrt{7}$

Answer:

Slope m = 3

General Formulas and Concepts:

Algebra I

Slope-Intercept Form: y = mx + b

m - slope
b - y-intercept

Step-by-step explanation:

Step 1: Define

y = -1 + 3x

Step 2: Rewrite

Rearrange

y = 3x - 1

Step 3: Break Function

Identify parts

Slope m = 3

y-intercept b = -1

Use the function below to find F(1). F(t) = 2•1/2^3t

stiv31 [10]

Answer:

D) 1/4

Step-by-step explanation:

To solve this, first lets figure out what this variable is. We know we must multiply by t. Well, looking at it, we know that t is one. So lets plug that in.

2*1/2^3(1)

Now we need to figure out what the exponent is that 2 will be raised to. To find that, find out what 3 times one is.

2*1/2^3

Now we need to solve the exponent.

2*1/8

Remember, 2 cubed is eight.

Now we need to find out what 2*1/8 is. To solve this more easily, I am going to turn two into a fraction. This will give us 2/1*1/8. Now we cross multiply, multiplying the numerators by the numerators, and the denominators by the denominators. Remember, the numerator is the top number, and the denominator is the bottom number.

If we do that, we get:

2/8

If we simplify it, we get 1/4. So the asnwer is D) 1/4
