how do i figure this out
Answer:
x=−4/5 or x=−3
Step-by-step explanation:
Step 1: Factor left side of equation.
(5x+4)(x+3)=0
Step 2: Set factors equal to 0.
5x+4=0 or x+3=0
x=−4/5 or x=−3

What is the slope and Y Intercept?
Answer: m is the slope and b is the y-intercept.
Step-by-step explanation:
it is understandable that the x has a coefficient of 1, so the m is 1 . and the y-intercept( b ) is −4 .
Point B(4, 3) is reflected over the y-axis. What are the coordinates of the resulting point, B′?

Twelve eggs cost $2.04 how much would 18 eggs cost?
Answer:
18 eggs would cost $3.06 :)
Step-by-step explanation:
Answer:
If 12 eggs cost $2.04, then figure out how much 1 egg costs. You do that by dividing the total by the amount = 0.17. Take that number and multiply by how many eggs and you'll get the total which is $3.06
The hypotenuse of a right triangle is 10 inches long. The longer leg is 2 inches longer than the shorter leg. Find the side lengths of the triangle.
Answer: Shorter leg = 6 inches
Longer leg = 6+2 = 8 inches
Step-by-step explanation:
Let the shorter leg bw represented by x.
Therefore, the longer leg will be x+2.
The hypothenuse is 10inches
We should note that in Pythagoras theorem, the square of the longer and shorter side equals the square of the hypothenuse. This will be:
x² + (x+2)² = 10²
x² + x² + 4x + 4 = 100
2x² + 4x = 100 - 4
2x² + 4x = 96
2x² + 4x - 96 = 0
x² + 2x - 48 = 0
x² + 8x - 6x - 48 = 0
x(x + 8) -6(x + 8) = 0
x - 6 = 0
x = 0+6.
x = 6
Shorter leg = 6 inches
Longer leg = 6+2 = 8 inches

Answer:
x = 4.5
Step-by-step explanation:
Given a segment joining the midpoints of 2 sides of a triangle, then
the segment is half the length of the 3rd side, that is
5x = 0.5 × 45 = 22.5 ( divide both sides by 5 )
x = 4.5
The volume of a cylinder is 80 cubic centimeters. If the diameter and
height of the cylinder are multiplied by 4/5, what is the volume of the new
cylinder?
Answer:2 yds and h
Step-by-step explanation:
The volume of the new cylinder will be equal to 40.96 cubic centimeters.
What is the volume of a cylinder?The amount of space inside a cylinder is its volume. You can find it by dividing the base area by the height.
The formula to calculate the volume of the cylinder is given below:-
V = πr²h
Given that volume of a cylinder is 80 cubic centimeters. The diameter and height of the cylinder is multiplied by 4/5. The new volume will be:-
Vi= πr²h = 80 cubic centimeters.
The new volume will be calculated as:-
Vn= π (4/5r)²(4/5)h
Vn = (64 / 125 ) πr²h
Vn = (64 / 125 ) x Vi
Vn = (64 / 125 ) x 80
Vn = 40.96 cubic centimeters.
Therefore, the volume of the new cylinder will be equal to 40.96 cubic centimeters.

Which justification can be used to demonstrate the graph is correct?
The justification (D) shading is to the left because (0, 0) does not satisfy the inequality option (D) is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.
We have inequality:
[tex]\rm x+3.5 < \dfrac{1}{10}(y-2)^2[/tex]
If plug (0, 0)
0 + 3.5 < 4/10
Which is not true.
Thus, the justification (D) shading is to the left because (0, 0) does not satisfy the inequality option (D) is correct.

Step-by-step explanation:
XOXO
KIT
Answer:
x = 2, x = 4
Step-by-step explanation:
Begin by letting f(x) = 0 , that is
x² - 6x + 8 = 0
Consider the factors of the constant term (+ 8) which sum to give the coefficient of the x- term (- 6)
The factors are - 2 and - 4 , since
- 2 × - 4 = + 8 and - 2 - 4 = - 6 , then
(x - 2)(x - 4) = 0
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x - 4 = 0 ⇒ x = 4
