Answer:

y = 2x - 11

Step-by-step explanation:

The "rate of change" is the coefficient of x when the function is written in this form:

y = mx + b

That coefficient will be positive when the function has a positive rate of change.

y = 2x - 11 . . . has a positive rate of change

GIVING OUT BRAINLIEST!! All sacks of sugar have the same weight. All sacks of flour also have the same weight, but not necessari

Vsevolod [243]

Answer:

flour = 11.5, sugar has to be equal to 2.75 pounds.

Step-by-step explanation:

your 2 inequalities are:

2x + 3y <= 40

y <= 2x + 6

the second equation can be shown as:

-2x + y <= 6

solve the equality portion of these 2 inequalities.

those are the following equations:

2x + 3y = 40

-2x + y = 6

add these equations together and solve for y to get

y = 11.5

that appears to be a break even point.

when y = 11.5, the first inequality is solved as follows:

2x + 3y <= 40

replace y with 11.5 and the inequality becomes:

2x + 34.5 <= 40

solve for x to get

x <= 2.75

when y = 11.5, the second inequality is solved as follows:

-2x + y <= 6

replace y with 11.5 and the inequality becomes:

-2x + 11.5 <= 6

solve for x to get x >= 2.75

this indicates that, when y = 11.5, x has to be equal to 2.75.

both constraints are satisfied.

To get julia's profit you will have to subtract the amount she spent on gas from the amount she was paid $12.00-$7.25=$4.75

Which point is not on the graph of the equation y=10+x

SCORPION-xisa [38]

Answer:

Step-by-step explanation:

Check all points:

A: x=0, y=10, then from the equality $10=10+0$ follows that A lies on the line.

B: x=3, y=13, then from the equality $13=10+3$ follows that B lies on the line.

C: x=8, y=2, then from the inequality $2=10+8$ follows that C doesn't lie on the line.

D: x=5, y=15, then from the equality $15=10+5$ follows that D lies on the line.

How do you solve this? <br> Look at attached file please...I'm really confused!

Answer:

X=18, Y=6

Step by Step Explanation:

This is a little long winded.. Let's solve for Y first.

First looking at the problem, you can note a few things. First of all, there is an Isosceles triangle, and there is an equilateral triangle. Where they connect, there is a 90° angle.

Now, all equilateral triangles have the same angle measurement. 60°. Now, if you look where the right angle is, it is showing a 60° angle, a total of 90°, and an unknown area. So simply subtract. 90-60=30. Divide that by 5, and you have your answer of 6.

Now let's solve X. X is very simple. On an isosceles triangle, the two top sides are the same length. And one of the top sides is the same size as the equilateral triangle. And on equilateral triangles, all sides are the same.

So the 11 transfers over to the X side. So let's make a small equation. 11=X-7. To make it even, let's add 7 to both sides. 11+7=X+7-7. Simplify to get 18=X, which is your answer.
