You dont have anything that we can answer to.
I’m guessing you meant 4x^2 (x to the power of two or x squared) rather than 4x2 (4 multiplied by two, meaning 8).
4x^2 -(-3x-8)
= 4x^2 +3x +8
72-2 = 70
Answer:
We can make around 7 loaves of bread with 37 cups of flour.
Step-by-step explanation:
Given that 5 cups of flour to bake a loaf of bread.
i.e.
5 cups of flour = 1 loaf of bread
Thus,
37 cups of flour can be determined by dividing 37 by 5.
37/5 = 7.4
= 7 loaves of bread (rounding to the whole number)
Therefore, we can make around 7 loaves of bread with 37 cups of flour.
Answer:
y = -3x + 7
Step-by-step explanation:
Choosing two points from the given table:
Let (x1, y1) = (-3, 16)
(x2, y2) = (-1, 10)
Plug these given values into the slope formula:
m = (y2 - y1)/(x2 - x1)
= (10 - 16) / (-1 - (-3))
= -6 / (-1 + 3)
= -6/2
= -3
Therefore, the slope is -3.
Next, choose one of the points and plug into the <u>point-slope form</u>:
Let's use (-1, 10) as (x1, y1):
y - y1 = m(x - x1)
y - 10 = -3(x - (-1))
y - 10 = -3(x + 1)
y - 10 = -3x - 3
Add 10 on both sides to isolate y:
y - 10 + 10 = -3x - 3 + 10
y = -3x + 7
40 meters is 12.00 seconds per meter/ 0.08 meters per seconds
