Answer:
x=4
Step-by-step explanation:
y = 2x - 8
Let y =0
0 = 2x-8
Add 8 to each side
8 = 2x-8+8
8 = 2x
Divide each side by 2
8/2 = 2x/2
4 =x

Analyze the set below and complete the instructions that follow.
C= {x|x<-42}
Use set-builder notation to define the complement of the set. U=R.
A. C^c=Ø
B. C^c={c|c<=-42}
C. C^c={x|x>=-42}
D. C^c={x|xeR}
Answer:
C
Step-by-step explanation:
Given: the set is defined as [tex]C=\left \{ x|x<-42 \right \}[/tex]
To find: Set builder form of the complement of the set C.
Solution:
A set is a well-defined collection of objects. Set-builder form is used to denote the elements of the set. This form can also be used to express sets using an interval or an equation.
Complement of set A refers to elements not in A.
For [tex]C=\left \{ x|x<-42 \right \}[/tex],
[tex]C^c=\left \{ x|x\geq -42 \right \}[/tex]
Option C is correct.

Answer:
The answer is 10
Step-by-step explanation: So first we divided 15 by 3 which is 5. Then we times 4 and 5 which is 20. 10+x=20, so x = to 10
Answer:
x = 10
Step-by-step explanation:
4/3 = (x+10)/15
Using cross products
15*4 = 3*(x+10)
60 = 3(x+10)
Divide each side by 3
60/3 = 3/3(x+10)
20 = x+10
Subtract 10 from each side
20-10 = x+10-10
10 = x
A rectangle's length is 4 more than twice its width. Its
area is 240 square centimeters.
Complete the work to find the dimensions of the
rectangle.
w(2w + 4) = 240
2w2 + 4w = 240
2w2 + 4w - 240 = 0
2(w + 12)(w - 10) = 0
What is the width of the rectangle?
2w + 4 A = 240 cm2
What is the length of the rectangle?
w
Answer:
Step-by-step explanation:
width = w
Length = 2w + 4
Area = 240 sq. cm
length * width = 240
(2w + 4) * w = 240
2w *w + 4*w = 240
2w² + 4w = 240
2w² + 4w -240 = 0
2(w²+2w - 120) = 0
2(w² + 12w - 10w - 10*12)=0
2 (w[w + 12] - 10[w + 12] ) = 0
2 (w + 12) (w-10) = 0
Ignore (w + 12) because measurement wont be in negative value
w - 10 = 0
w = 10
Width = 10 cm
length = 2w + 4 = 2*10 + 4 = 20 + 4
Length = 24 cm
Answer:
Width = 10
Length = 24

Which of the following could be a solution to x^2 = 400
a. -200
b. -20
c. 40
d. 100
Answer:
a. -200
Step-by-step explanation:
Square root both sides:
x = +/- 200
x = -200, 200
x = -200
Answer:
b
Step-by-step explanation:
Given
x² = 400 ( take the square root of both sides )
x = ± [tex]\sqrt{400}[/tex] = ± 20
Thus x = - 20 is a solution of the equation → b

The perimeter of the figure is, 25.12 feet
And, the area of the figure is, 50.24 feet²
What is mean by Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
We have to given that;
The radius of the partial circle with center A is,
⇒ 4 feet.
Now,
We know that;
Perimeter of circle = 2πr
Here, r = 4 feet
⇒ Perimeter of circle = 2πr
⇒ Perimeter of circle = 2 × 3.14 × 4
⇒ Perimeter of circle = 25.12 feet
And, Area of circle = πr²
⇒ Area of circle = 3.14 × 4²
⇒ Area of circle = 50.24 feet²
Thus, The perimeter of the figure is, 25.12 feet
And, the area of the figure is, 50.24 feet²

The maximum number of large binders she can buy is 5.
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Given that:-
Allison is buying binders for school. Small binders cost $3 each, and large binders cost $5 each. If Allison needs to buy at least 12 binders and has no more than $45 to spend, what is the maximum number of large binders she can buy?From the given data we can form the equation let n1 and n2 are the numbers of the small and the large binders and Sb and Lb are the cost of each binder.
n₁Sb + n₂Lb = 45 ................................1
n₁ + n₂ = 12
Now put the value of n₁ in equation 1.
( 12 - n₂ )3 + 5n₂ = 45
36 - 3n₂ + 5n₂ = 45
2n₂ = 9
n₂ = 4.5
n₂ ≅ 5
Therefore the maximum number of large binders she can buy is 5.

Answer:
1/6
Step-by-step explanation:
1/2=3/6
3 other designs
1/6+1/6+1/6=3/6
3/6+3/6=1
The fraction of the votes each of the other designs get is x/6.
Given that, you create four t-shirt options and send them to your family to vote on their favorite design.
What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Let the number of family members be x.
Half of the votes were design #1.
So, x/2 members voted for design #1.
Remaining family members x/2 voted evenly between the other three designs.
Thus, x/2 ÷ 3
= x/6

Find the solution to the system of equations y=2x+1 y=x^2+2x-15
Answer:
x = 4 OR x = -4
Step-by-step explanation:
To find the solution, you can set both equations equal to one another:
(1) y=2x+1; (2) y=x^2+2x-15
2x+1 = x^2+2x-15
Then solve for the x-values that make this true.
2x+1 = x^2+2x-15
1 = x^2 - 15
16 = x^2
x = 4 OR x = -4
