So, we know that 40 hours is $390 and 4 * 10 = 40, therefore, we just have to divide $390 by 4 to get $97.5, meaning that Zoe made $97.5 in 10 hours of work.
Hey, it’s very easy. You just need to do like that:
z-2z-3=-7
z-2z= -7+3
-1z = -4 | : (-1)
z = 4
The answer is 4.
Answer:
33
Step-by-step explanation:
put 4 in for x and then solve
5+7(4)
5+28

Answer:
I'm going to do 1 as an example and using what I've taught you, you have to do the rest. Hope my explanation helps.
Step-by-step explanation:
We are given the points (-2, -4) and (-1, -1)
We need to find the slope.
The equation to do so is y2 - y1 / x2 - x1
lest say:
-2 is x1
-4 is y1
-1 is x2
-1 is y2
-1 - (-4) / -1 - (-2)
3/1 = 3
slope (m) = 3
We already know the y-intercept is 2
The equation of a line is y = mx + b
For this problem we just have to substitute what we already know.
y = (slope)x + y-intercept
y = 3x + 2
*TIP*
If the y-intercept is negative, let's say: b = -5 (using slope 8)
the equation will be y = 8x - 5
Hope this helps. I wish you all the best. :)
