Answer:

3

Step-by-step explanation:

Given 

f(x) = - 3x + 5 

f(x) = - 4 

-3x + 5 = - 4 

- 3x = - 4 - 5 

- 3x = - 9 

x = 3 

Hope it will help :)

Answer:

x=3

Step-by-step explanation:

i believe it's like this, i am not sure

Y= -3x +5

-4= -3x+5

subtract 5 on both sides

-9= -3x

divide -3 on both sides

x=3

I need help with this question please and thank you

Nadusha1986 [10]

we have the number

$6-\sqrt[]{-40}$

Remember that

i^2=-1

substitute

$6-\sqrt[]{(i^2)40}$ $6-2i\sqrt[]{10}$

therefore

the real part is 6

the imaginary part is -2√10

What the slope (0,-1) and (2,-5)

Answer:

-4/2, or finding slope is (difference of y)/(difference of x) inserting those numbers into the equation would be (-5-(-1))/(2-0), which would become -4/2, which is basically -2.
