Answer: y = 2x + 20
Step-by-step explanation: slope, y2 - y1/x2 - x1
replace it with these numbers 120 - 60/50 - 20=60/30
than,simplified it we get 2/1. so, now we have the slope of our equation
y = 2x + b. but we still have b (or where the y intersects.) now are slope we have to change it to 1/2 because we are going backwards. So multiply 60 by .5, Thus will give us 30
Now we have y = 2x + 30, But that's not one of your answer,
So y = 2x + 20 cant be -20 because this is a positive y intersect and We know it is a slope of 2.
Therefore the answer is : y = 2x + 20
ALSO I got it correct on the test!!
Answer:
Step-by-step explanation:
<u>Given the scale factor:</u>
Since the cylinders are similar, the other dimensions should have same scale factor of 1/3.
<u>The volumes are:</u>
<u>Ratio of volumes is the cube of the scale factor, as the volume is the product of 3 dimensions:</u>
- v/x = k³
- 67/x = (1/3)³
- x = 67*27
- x = 1809 cm³
Answer:
2nd option
Step-by-step explanation:
To find g(f(x)) , substitute x = f(x) into g(x)
g(x + 3) = + 7
Answer: D. The quadratic parent function.
Step-by-step explanation:
Quadratic functions have a parabola shape like the graph shown in the image.
Answer:
b = 61
Step-by-step explanation:
The sum of the two angles is 90 degrees
b+29 = 90
Subtract 29 from each side
b+29 -29 = 90 -29
b = 61
