Answer:
y = 8x + 8
Step-by-step explanation:
The y-intercept is already given so we have our b = 8 so y = mx + b becomes y = mx + 8. Now we need to figure out the slope so looking at the chart I need to figure out what number when multiplied by the x value and added to b equals the y value. The answer is 8 because when we multiply it by 1 and add it to 8 we are left with 16, which supports the chart. The equation in slope intercept form is now y = 8x + 8
Answer:c is the correct answer
Step-by-step explanation:
A repair company's charge for repairing a certain type of copy machine fits the model y = 47.38 + 0.617x
where y is the number of dollars charged and
x is the number of minutes the repair person is on the job.
Therefore, to determine the number of minutes that it would take for the cost of repair to reach $130, we would substitute y =130 into the given model. It becomes
130 = 47.38 + 0.617x
0.617x = 130 - 47.38 = 82.62
x = 82.62/0.617 = 134 minutes
Answer:
x is 0.
Step-by-step explanation:
Subtract both sides by 3x. Then, you will have 10= x+10. Subtract 10 on both sides to isolate x, then you will have x=0. Therefore, this equation on both sides has a solution of 0. Hope this helps!
Answer:
<h3> -3 * r
</h3>
Step-by-step explanation:
at least means it can be 57 or higher
We need to find a distance between this to points.
D=√((x2-x1)²+(y2-y1)²)
For complex plain, the real part of the complex number plays a role of x,
and number of an imaginary part plays a role of y.
So,
D=√((8-2)² +(7+1)²)√ = √(36+64)=√(100)=10
Answer is D.10
