Set up a ratio 3 cups of flour / 5 cups of flour = x cups of sugar/ 2 cups of sugar.

Cross multiply:

(3x2) / 5x = 6 = 5x

Divide both sides by 5

X = 6/5 cups of

Answer:

(3,2)

Step-by-step explanation:

Y=-2x+8 equation 1

y=x-1 equation 2

x-1=-2x+8 substi y of second equation into y of first equation.

3x=9

x=3

solve for y by putting the  x value into either equation

y=x-1

y=3-1

y=2

A line segment whose endpoints are (2,6) and (8,y) is perpendicular to a line whose slope is -4. What is the value of y?
Mariulka [41]
If the line segment is perpendicular to a line with the slope of -4, that means the line segment has a slope of 1/4.

First let's make an equation for the line segment using the slope of 1/4 and the point at (2,6) to find the final piece, the y-intercept

y = mx + b
6 = 1/4(2) + b
6 = 2/4 + b
24/4 = 2/4 + b
22/4 = b

y = 1/4 x + 22/4
6 = 1/4(2) + 22/4
6 = 2/4 + 22/4
6 = 24/4
6 = 6 <-- proves that this equation is correct

Now you may plug in the x to find y. ( 8 , y )
y = 1/4(8) + 22/4
y = 8/4 + 22/4
y = 30/4 = 15/2 = 7.5

In Exercise,find the horizontal asymptote of the graph of the function.<br> f(x) = 2-xx
Dafna1 [17]

Answer:

y=2

Step-by-step explanation:

Given the function y = 2-x ^ 2, we have that the horizontal asymptote is y = 2 since for x = 0 y = 2, that is, it is a line parallel to the axis = 0X where y has a value k, in this case y = 2
