Answers

Answer 1
1. x + 8 = 32
Subtract 8 from both sides to isolate x.
x = 24

2. 4y = 48
Divide each side by 4 to isolate y
y = 12

3. 2z - 18 = 116
Add 18 to each side, then divide each side by 2 to isolate z
z = 67

4. 8a + 12 = 84
Subtract 12 from each side and divide each side by 8 to isolate a.
a = 9

5. b + 11 = 37
Subtract 11 from each side to isolate b
Age = 26 years

7.
a. 2x - 7 = 43
Add 7 to each side and divide by two to isolate x.
x = 25
Carley is 25 years old and Amber is 18 years old.

b. x + 2x + 25 = 160
Combine like terms, subtract 25 from each side, and divide each side by 2 to isolate x.
Nevin (x) has collected 45 buttons. Jordan has collected 115 buttons.

c. x + x + 3 + x - 29 = 64
Combine like terms, add 26 to each side, and divide by 3 to isolate the variable.
x = 30
Mom (x) is 30 years old, Dad is 33 years old, and Brittany is one year old.

d. x + 2x + 2x - 7 = 138
Combine like terms, add 7 to each side, and divide by 5 to isolate the variable.
x = 29

Step-by-step explanation:

the length of a rectangle is 4 feet longer than its width.its area is 32 square feet.what are its dimensions?

Answers

Answer: Length=8, Width=4

Step-by-step explanation: I did this by trial and error, but you can also use an equation. The length is x+4, the width is x. Your equation would be x(x+4)=32. That is equal to x^2+4x=32. Solve this by completing the square. X^2+4x+ (4/2)^2=32+ (4/2)^2

X^2+4x+4=36. (X+2)(x+2)=36. X+2=6, x=4.

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = - 8x + 3 ← equation of line

Abigail is buying new chairs to upgrade her restaurant. A set of 6 wooden chairs costs $444. A set of 8 metal chairs costs $720. How much more do the metal chairs cost per chair?

Answers

Answer:

$16.00

Step-by-step explanation:

6 wood chairs are 444 which is 74.00 a piece

8 metal chairs are 720 which is 90.00 a piece

90-74= 16

The metal chairs are $16.00 more

If Abigail is buying new chairs to upgrade her restaurant. A set of 6 wooden chairs costs $444. A set of 8 metal chairs costs $720. Then the metal chairs are $16.00 more

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

Abigail is buying new chairs to upgrade her restaurant.

A set of 6 wooden chairs costs $444.

6W=444

W=444/6

W=74

A set of 8 metal chairs costs $720.

8M=720

M=720/8

M=90

Now we need to find how much more do the metal chairs cost per chair.

We need to find the difference

90-74

16

Hence the metal chairs are $16.00 more

Answer:

[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex] is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Step-by-step explanation:

Given the function

[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex]

As the highest power of the x-variable is 3 with the leading coefficients of 1.

So, it is clear that the polynomial function of the least degree has the real coefficients and the leading coefficients of 1.

solving to get the zeros

[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex]

[tex]0=x^3-6x^2+3x+10[/tex]              ∵  [tex]f(x)=0[/tex]

as

[tex]Factor\:x^3-6x^2+3x+10\::\:\left(x+1\right)\left(x-2\right)\left(x-5\right)=0[/tex]

so

[tex]\left(x+1\right)\left(x-2\right)\left(x-5\right)=0[/tex]    

Using the zero factor principle

if  [tex]ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]

[tex]x+1=0\quad \mathrm{or}\quad \:x-2=0\quad \mathrm{or}\quad \:x-5=0[/tex]

[tex]x=-1,\:x=2,\:x=5[/tex]

Therefore, the zeros of the function are:

[tex]x=-1,\:x=2,\:x=5[/tex]

[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex] is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Therefore, the last option is true.
