Consider x+4=x+8. What values could be substituted for x to make this a true number sentence?
Schach [20]

This looks unusual but let's try it.

x+4=x+8

Let's move the x vales to the left and numbers to the right.

x-x=8-4

0=-4

Hm. This doesn't work, does it?

This equation has no solution. If you believe you typed it wrong, correct it in the comment seciton.

Find the maxium valve C=6x+2y. Subject to the following constraints x≥0, x≤5, y≥0, 4x-y≥1
Vadim26 [7]

Answer:

The maximum value of C is 68

Step-by-step explanation:

we have the following constraints

x\geq 0 ----> constraint A

x\leq 5 ----> constraint B

y\geq 0 ----> constraint C

4x-y\geq 1 ----> constraint D

Find out the area of the feasible region, using a graphing tool

The vertices of the feasible region are

(0,0),(5,19),(5,0)

see the attached figure

To find out the maximum value of the objective function C, substitute the value of x and the value of y of each vertex in the objective function and then compare the results

C=6x+2y

For (0,0) -----> C=6(0)+2(0)=0

For (5,19) -----> C=6(5)+2(19)=68

For (5,0) -----> C=6(5)+2(0)=30

therefore

The maximum value of C is 68

Find the measure of <_B (show work if possible)
Mandarinka [93]

Answer: <b is 59.3 degrees

Step-by-step explanation:

Triangles have total of 180 degrees

The bottom two points are both 4y

To solve: 4y+4y+(3y+14)=180

11y+14=180

-14

11y=166

Divide by 11

Y=15.1

So plug that in for y

3(15.1)+14=B

59.3

Hope this helped

Find the slope? Work on how you got answer please
Anastaziya [24]
The slope is 2.

Reason: you find the slope by dividing the difference of the y-coordinates (5 and 9) by the difference of the x coordinates (1 and 3)
9-5=4
3-1=2
4 divided by 2 =2

A recipe for a strawberry smoothie calls for three eights cup of strawberries. Pat wants to make two servings of the strawberry
GrogVix [38]
If one serving takes 3/8 of a cup and she wants two servings, just multiply 3/8 by 2.

2 * (3/8) = 6/8 or 3/4 of a cup.
