Solve for x 9z = 5z + 20 I think they made a mistake

Mathematics

Alina [70]3 years ago
7 0

Answer:

Z = 5

Step-by-step explanation:

Step 1: Subtract 5z from both sides.

9z−5z=5z+20−5z

4z=20

Step 2: Divide both sides by 4.

4z/4 = 20/4

z=5

Hope this helps.

What is slope-intercept form of a line that passes through points (2,11) and (4,17)?​
kramer

Answer:

y = 3x + 5

Step-by-step explanation:

Okay, so first we do the equation for rise over run which is y2 - y1/ x2 - x1

so plug the numbers 11 - 17/ 4 - 2 getting the slope -3, now since we found the slope we need to find the intercept form, what you have to do now is plug in a coordinate from the x value and y value one of the pairs essentially so,

y = 3x + b, I chose your first pair

11 = 3 x 2 + b

equals to,

11 = 6 + b

now we want b, by itself.

5 = b

so the total intercept form answer is

y = 3x + 5

I will check over it,

11 = 3 x 2 + 5

11 = 11

I hope this helped!

Deffense [45]
First you divide 1200 by 25 (1200/25) it comes out to 48. 
That means the he types at a rate of 48wpm. So then all you have to do is multiply 48 and 45 and you get 2160 words.
