Answer:
use 2 variable for the problem. say pear=x apple=y.
3x+4y=1.6
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
find the area of the circles on the top and bottom with area of a circle being pie r squared
=25.12
Find the area of the rectangle, with the height being one side and the circumference of the circle being the other
add the two together to get 150.72 and round
It's simple .....
just subtract R and C.....
so 50x+10-10x-275
= 40x-265
so the answer is B
The volume will decrease.
If everything else remains the same then it will decrease. If other sides were increased proportionally then it would stay the same. It would increase if other sides were enlarged more than the length was shortened.
Answer: D. y = 3x − 1
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = intercept
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis
change in the value of y = y2 - y1
Change in value of x = x2 -x1
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
From the graph,
y2 = 2
y1 = - 1
x2 = 1
x1 = 0
Slope,m = (2 - - 1)/(1 - 0) = 3/1 = 3
To determine the intercept, we would substitute x = 1, y = 2 and m= 3 into y = mx + c
y = mx + c. It becomes
2 = 3 × 1 + c = 3 + c
c = 2 - 3 = - 1
The equation becomes
y = 3x - 1
