1/4(z +3z)+ 7=−z + 1 please help with this ive been stuck

Answers

Answer 1

Answer:

z = -3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

z+7=−z+1

Step 2: Add z to both sides.

z+7+z=−z+1+z

2z+7=1

Step 3: Subtract 7 from both sides.

2z+7−7=1−7

2z=−6

Step 4: Divide both sides by 2.

2z   =  −6

2      2

z=−3

Joe goes to the store to buy milk that cost x + $3, bread that cost x + $2.25, and 3 bags of potato chips that cost x + $1.50 each. Write an equivalent expression to represent what he spent.

Answers

Given:

Milk cost = x + $3,

Bread cost = x + $2.25,

3 bags of potato chips cost = x + $1.50 each.

To find:

The equivalent expression to represent what he spent.

Solution:

1 bag of potato chips cost = x + $1.50

3 bag of potato chips cost = 3(x + $1.50).

Total cost = Milk cost + Bread cost + Cost of 3 bags of potato chips

[tex]\text{Total cost}=(x+\$3)+(x+\$2.25)+3(x+\$1.50)[/tex]

[tex]\text{Total cost}=x+\$3+x+\$2.25+3x+\$4.50[/tex]

[tex]\text{Total cost}=(x+x+3x)+\$(3+2.25+4.50)[/tex]

[tex]\text{Total cost}=5x+\$9.75[/tex]

Therefore, the required expression is 5x+$9.75.

A cement path consists of six equal-sized cement squares arranged in a row to form a rectangle. If the total area of the path is 96 square feet, what is the length in feet of the path?

Answers

Answer:

24 feet

Step-by-step explanation:

Given that:

The length of the rectangle is 6 times the side of a cement square.

Now, this rectangle is formed from 6 squares;

The total area of the path of this square = 96 square feet;

The area of each square now = 96/6 = 16 square feet

Recall that:

Area of a square = S²

where S is the side length

16 = S²

S = [tex]\sqrt{16}[/tex]

S = 4 ft

The length of the path in feet now is: L × w

= 6 × 4

= 24 feet.

Given: 4d=1/3(c-d) Proof= c=13d

Answers

Proof:

Multiply both of the sides by 3. You would get 12d = c - d. Add d on both sides, and you would get c = 12d

Here, we are required to proof c = 13d from 4d=1/3(c-d)

Ultimately, c = 13d (proof)

We have;

4d=1/3(c-d)

Cross product

4d × 3 = c - d

therefore, By collecting like terms;

C = 12d +d

and Ultimately, c = 13d ......

11) Which of the following is zero of the polynomial x^3+x^2+x+1

1
-1
both options 1 and 2
None
please answer​

Answers

Answer:

Answer: -1

Step-by-step explanation:

The Polynomial Remainder Theorem

It states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).

We have the polynomial:

[tex]f(x)=x^3+x^2+x+1[/tex]

And we need to determine if x=1 and/or x=-1 are zeros of the polynomial.

Considering the polynomial remainder theorem, if we try any value for x, and the remainder is zero, then that value of x is a root or zero of the polynomial.

Find:

[tex]f(1)=1^3+1^2+1+1[/tex]

f(1)=4

Thus, x=1 is not a zero of f(x)

Now, find:

[tex]f(-1)=(-1)^3+(-1)^2+(-1)+1[/tex]

[tex]f(1)=-1+1-1+1=0[/tex]

Thus, x=-1 is a zero of f(x)
