What is the solution for xin the equation?<br> 4x-3 + 5 = 2x + 7 - 8x
Greeley [361]

Answer:

x = 1/2

Step-by-step explanation:

4x-3 + 5 = 2x + 7 - 8x

Combine like terms

4x +2 = 7-6x

Add 6x to each side

4x+2+6x = 7-6x+6x

10x+2 = 7

Subtract 2 from each side

10x+2-2 = 7-2

10x = 5

Divide by 10

10x/10 = 5/10

x = 1/2

Write the linear equation that gives the rule for this table.
Zinaida [17]

Answer:

f(x) = -7x + 1

Step-by-step explanation:

Slope intercept form is

y = mx + b

m is slope

b is y-intercept

--------------------------

y decreases by 7 for each increase of 1 in x

slope = -7

to find "b" plug in one of the points and m = -7

using point (3, -20)

y = mx + b

-20 = -7(3) + b

-20 = -21 + b

b = 1

The equation is

f(x) = -7x + 1

A coach purchases 47 hats for his players and their families at a total cost of $302. The cost of a small hat is $5.50. A medium
blagie [28]

Answer:

d. 23

Step-by-step explanation:

 x: small hat

 y: medium hat

 z: large hat

 We now write the system of equations:

 x + y + z = 47

 5.50x + 6y + 7z = 302

 -3x + y = 0

 We can write the system in matrix form as:

 Ax = b

 Where,

 A = [1  1  1; 5.50  6  7; -3  1  0]

 b = [47;  302;  0]

 x = [x;  y ;  z]

 Solving the system we have:

 x = 6

 y = 18

 z = 23

hope this helps
