Answer:
equation: y = -4x + 7
slope: -4
y-intercept: 7
Step-by-step explanation:
in order to make this equation into slope-intercept form, you have to isolate the y
to do that, you can subtract the 4x on both sides, which will leave y by itself
4x + y = 7
-4x -4x
y = -4x + 7
the slope is -4
and the y-intercept is 7
-19,21.7,45,|-65| this is the order
Answer:
Step-by-step explanation:
To find the time at which both balls are at the same height, set the equations equal to each other then solve for t.
h = -16t^2 + 56t
h = -16t^2 + 156t - 248
-16t^2 + 56t = -16t^2 + 156t - 248
You can cancel out the -16t^2's to get
56t = 156t - 248
=> 0 = 100t - 248
=> 248 = 100t
=> 2.48 = t
Using this time value, plug into either equation to find the height.
h = 16(2.48)^2 + 56(2.48)
Final answer:
h = 40.4736
In a stem plot the numbers on the left side of the line are called the stem and the value on the right side are called the leaves. The stem represents the tens place while the leaves represent the ones place of a number.
