Answer:
The y intercept is (0,-8)
Step-by-step explanation:
To find the y intercept, set x = 0 and solve for y
-4x -2y = 16
-4(0) -2y =16
-2y = 16
Divide by -2
-2y/-2 = 16/-2
y = -8
The y intercept is (0,-8)
Answer: y = 2x+22
========================================================
Explanation:
The equation y = 2x+5 is in the form y = mx+b
m = 2 = slope
b = 5 = y intercept
Parallel lines have equal slopes, but different y intercepts. So the answer will be in the form y = 2x+c, where b and c are different numbers. Since b = 5, this means c must be some other number. If c = 5, then we'd have the exact same line.
Let's plug in (x,y) = (-5,12), along with the slope m = 2, and solve for c
y = mx+c
12 = 2(-5)+c
12 = -10+c
12+10 = c
22 = c
c = 22
Since m = 2 and c = 22, we go from y = mx+c to y = 2x+22
The equation of the parallel line is y = 2x+22
The graph is below.
4 rectangles are 6 x 4
4 triangles are 4x 4
1 square is 6x 6
Area :
6 x 4 = 24 x 4 = 96
1/2 x 4 x 4 = 8 x 4 = 32
6 x 6 = 36
96 + 32 + 36 = 164 square inches.
The answer is A
The probability would be written as number of red marbles/ total number of marbles.
Probability of picking red would be 6/15.
Divide to get the percent: 6/15 = 0.4 = 40%
