30 FREE pts Which equation could have been used to create this function table? A. y = 5x B. y = x + 1 C. y = x + 2 D. y = 2x
2 answers:
We want to find the slope of this function first to help us get our answer.
The slope of a function can be found with the following formula:
Take any two points from the table to plug into the equation. We'll use (1,2) and (4,8):
The slope of our function will be 2.
All of the answers are in slope-intercept form. Slope-intercept form uses the following formula:
m is the slope, and b is the y-intercept of the equation.
We know that our slope is 2. The only answer with a slope of 2 is y = 2x.
The answer is <span>D. y = 2x. </span>

Answer:
See the attached figure which represents the problem.
As shown, AA₁ and BB₁ are the altitudes in acute △ABC.
△AA₁C is a right triangle at A₁
So, Cos x = adjacent/hypotenuse = A₁C/AC ⇒(1)
△BB₁C is a right triangle at B₁
So, Cos x = adjacent/hypotenuse = B₁C/BC ⇒(2)
From (1) and (2)
∴ A₁C/AC = B₁C/BC
using scissors method
∴ A₁C · BC = B₁C · AC
Answer:
cups of butter should be use to keep the same ratio.
Step-by-step explanation:
Given:
A recipe for pie dough calls for a ratio of butter to flour of 1/4 :5/6.
If you plan to use 5 cups of flour.
Now, to find the butter should be used to keep the same ratio.
So, to get the quantity of butter by using unitary method:
If, cup of flour use then butter should be =
.
So, 1 cup of flour use then butter should be = =
.
Thus, for 5 cups of flour butter should be = =
.
Therefore, cups of butter should be use to keep the same ratio.
