Answer:
Third option (-3 and 2)
Step-by-step explanation:
You do not need graphs for this necessarily. you just have to build two equations:
0=x+3
0=x-2
if you solve them, the results are:
-3 = x
2 = x
Answer:
option 3 is correct that is (-3,2) is the solution.

What is the area of this irregular figure?
A figure can be broken into 2 rectangles. One rectangle has a base of 16 centimeters and height of 8 centimeters. The other rectangle has a base of 8 centimeters and height of 8 centimeters.
128 Centimeters squared
192 Centimeters squared
256 Centimeters squared
512 Centimeters squared
Answer:
192cm²
Step-by-step explanation:
If you cut the shape into 2 and you do 8×8 which is 64cm²
Then you work out the area of the other part of the shape which is 8×16=128cm² then add them two together which is 192cm²

What is the y-intercept of the quadratic function f(x) = (x-8)(x+3)
Answer:
-24
Step-by-step explanation:
To find the y intercept, plug x in as 0.
Answer:
-24
Step-by-step explanation:
Y intercept is where graph cuts the y axis and it satisfies x=0
So put x=0 in your equation
F(0)= -8 x 3
F(0)= -24
Therefore y-intercept= -24
i am having trouble i need help.
Answer:
A. y=2x-2
Step-by-step explanation:
Answer:
the answer is A
Step-by-step explanation:
to find the slope intercept formula u need the slope, the y-intercept, and the X and Y
1st step: find the slope and to find the slope, pick any two points from the line
point 1: (2,2)
point 2: (3,4)
slope= y2-y1/x2-x1
4-2/3-2=2/1 or 2
the slope intercept form is y=mx+ b, so now substitute the variables for the known
y=2
x=2
m=2
2=2(2)+b
solve the equation
2=4+b
subtract 4 on both sides
b=-2
the slope intercept form is y=2x-2
He Jones family has saved a maximum of $750 for their family vacation to the beach. While planning the trip, they determine that the hotel will average $125 a night and tickets for scuba diving are $75. The inequality can be used to determine the number of nights the Jones family could spend at the hotel750≥75 + 125h What value of h does NOT make the inequality true?
Answer:
h<0
Step-by-step explanation:
75+125h ≤ 750
h≤ 8.333
for negative values of h the inequality will not hold true

What is the volume of a sphere with the radius of 24
Answer:
[tex] \frac{4}{3?} \times 3.14 \times 24}^{3 [/tex]
Answer:
see below
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
V = 4/3 pi (24)^3
V = 4/3*13824 pi
18432 pi
If we approximate pi by 3.14
V =57876.48
Or using the pi button
V =57905.83579
Daniel cut a square cake vertically to make two rectangle slices. Each rectangle had a perimeter of 45 inches. How long is each side of the original square cake?
Answer:
15 inches
Step-by-step explanation:
As the square cake was cut in two equal pieces, we have that one side of the rectangle is the double of the other side, so we have that:
2*Length + 2*Width = 45
Length = 2*Width
So using the value of length in the first equation, we have:
4*Width + 2*Width = 45
6*Width = 45
Width = 7.5
Length = 2*Width = 15
So each side of the original cake is equal to the length of the rectangle pieces, that is, 15 inches.

In an all boys school, the heights of the student body are normally distributed with a mean of 69 inches and a standard deviation of 3 inches. Using the empirical rule, determine the interval of heights that represents the middle 95% of male heights from this school.
Answer:
Two intervals are 63 and 75
Step-by-step explanation:
Given:
Mean of students (μ) = 69 inches
Standard deviation (σ) = 3 inches μ
Find:
Interval of heights (95%) using empirical rule
Computation:
Interval of heights (95%) using empirical rule:
⇒ μ – 2σ = 69 - 2(3)
⇒ μ – 2σ = 69 - 6
⇒ μ – 2σ = 63
⇒ μ + 2σ = 69 + 2 (3)
⇒ μ + 2σ = 69 + 6
⇒ μ + 2σ = 75
Two intervals are 63 and 75

Solve the quadratic equation by completing the square. What are the missing pieces to the steps?
-27 = 4x²- 24x
-27 = 4(x²- 6x + 9)
9 =4(x²- 6x + 9)
9/4 = (x -3)
+__= x - 3
__ = x
Answer:
The missing pieces should be after line 3.
9/4 = (x - 3)^2
<=> (3/2)^2 = (x - 3)^2
<=> x - 3 = 3/2 or x - 3 = -3/2
<=> x = 3 + 3/2 or x = 3 - 3/2
<=> x = 9/2 or x = 3/2
Hope this helps!
:)
Answer:
I think the missing steps are:
[tex]\frac{3}{2}=x-3[/tex]
and
[tex]\frac{9}{2}=x[/tex]
Step-by-step explanation:
[tex]-27=4x^2-24x[/tex]
First, factor 4 to make isolate [tex]x^2[/tex]
[tex]-27=4(x^2-6x)[/tex]
Now, divide by 4.
[tex]-\frac{27}{4}=x^2-6x[/tex]
Complete the square by adding [tex](\frac{b}{2})^2[/tex]
[tex](\frac{b}{2})^2-\frac{27}{4}=x^2-6x+ (\frac{b}{2})^2[/tex]
[tex](\frac{6}{2})^2-\frac{27}{4}=x^2-6x+ (\frac{6}{2})^2[/tex]
[tex](3)^2-\frac{27}{4}=x^2-6x+ (3)^2[/tex]
[tex]9-\frac{27}{4}=x^2-6x+9[/tex]
Solve the difference.
[tex]\frac{9*4-27}{4}=x^2-6x+9[/tex]
[tex]\frac{36-27}{4}=x^2-6x+9 \\\frac{9}{4}=x^2-6x+9[/tex]
Factor the equation.
[tex]\frac{9}{4}=(x-3)(x-3)[/tex]
Rewrite it;
[tex]\frac{9}{4}=(x-3)^2[/tex]
Extract the square root.
[tex]\sqrt{\frac{9}{4} }=x-3[/tex]
Take the square root of 9 and 4.
[tex]\frac{3}{2}=x-3[/tex]
Add 3.
[tex]\frac{3}{2}+3=x[/tex]
Do the sum
[tex]\frac{3+2*3}{2}=x\\\frac{3+6}{2}=x\\\frac{9}{2}=x[/tex]

What is the slope of this line?
Answer:
the answer is m = 1/5
Step-by-step explanation:
A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The slope of the given equation of the line is 0.2.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,
y =mx + c, slope intercept form
y - y₁ = m(x - x₁), point-slope form
where,
x and x₁ are the coordinates of the x-axis,
y and y₁ are the coordinates of the y-axis,
m is the slope of the line, and
c is the y-intercept.
The equation of a line in the point-slope form is y–9=(1/5)(x-2). Therefore, the slope of the line is (1/5).
