It would be choice "D". When you change all these equations into slope-intercept form (Y=mx+b or Y equals the slope times "X" plus the y-intercept), choice "D" is the only one with the same slope which is the the value of "m" in slope-intercept form. In this case, when both equations in choice "D" is changed to slope-intercept form, both equations' slopes become -2. When slopes of two equations are the same, the lines are parallel to each other when graphed.
Since this is area you'll simply just do 18 x 29 which equals 522 and compare it to the amount of bricks she currently has. In this case, no, Sharon does not have enough bricks as she is 22 bricks short.
It takes 9 seconds to hit the ground.
Setting the equation equal to 0, we have:
0 = 144 + 128t - 16t²
Factoring out the GCF, we have
0 = 16(9 + 8t - t²)
Factoring out -1, we have:
0 = -16(-9 - 8t + t²)
In standard form, this is
-16(t² - 8t - 9) = 0
This is easily factorable; -9(1) = -9 and -9+1 = -8:
-16(t-9)(t+1) = 0
Using the zero product property, we know either t-9=0 or t+1=0; therefore t=9 or t=-1. Since negative time makes no sense, t=9.
Answer:
Step-by-step explanation:o
x + y = 10........(1)
x - y = 14..........(2)
Adding (1) and (2)
2x = 24
x = 24/2
x = 12
And x + y = 10.......(1)
12 + y = 10
y = 10 - 12
y = -2
The number are 12 and -2
Reformat the equation to be in terms of y.
4y= 3x-6
y=3/4x -6/4
The y intercept when x=0 is -6/4
The x intercept when y=0 is 2
Simply draw the graph using these two points
