Answer:
16
Step-by-step explanation:
Since line CE is equal to 32 and line DB is the bisector (cut into the middle) of line CE then line CF would be half of line CE. Hence the reason that line CF is equal to 16
What is the solution to the inequality -8x + 4 < -4?
Answer:
x > 1
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesStep-by-step explanation:
Step 1: Define
-8x + 4 < -4
Step 2: Solve for x
Subtract 4 on both sides: -8x < -8Divide -8 on both sides: x > 1Here we see that any value x greater than 1 would work as a solution.
what is the equation of the line with slope -3 and y-intercept 6? Express your answer in slope-intercept form.
Answer:
y=-3x+6
Step-by-step explanation:
Answer:
y = -3x + 6
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
SO
m = -3
b = 6
Thus,
y = -3x + 6
(BRAINLIEST + 30 POINTS) Gumballs cost $0.50 each, and jawbreakers cost $0.30 each. Bob has $3.00 to spend on candy.
Create an inequality that represents the number of gumballs and jawbreakers Bob can buy.
Answer:
3 gumballs and 5 jawbreakers = $3.00
Step-by-step explanation:
30 x 5 = $1.50 (One dollar and 30 cents)
50 x 3 = $1.50 (One dollar and 30 cents)
and if you add those together you get $3.00 because
50 + 50 = 100 or in this question $1.00 and when you add
$1.50 + $1.50 = $3.00
hope this helps!
Answer:
0.5g + 0.3j ≤ 3Step-by-step explanation:
Let number of gumballs be g and jawbreakers be j
Bob will spend 0.5g + 0.3j on candy and the total should not exceed $3.00
Required inequality is:

0.5 e + 20= 25
solving equations
Answer:
e = 10
Step-by-step explanation:
Simplifying
0.5e + 20 = 25
Reorder the terms:
20 + 0.5e = 25
Solving
20 + 0.5e = 25
Solving for variable 'e'.
Move all terms containing e to the left, all other terms to the right.
Add '-20' to each side of the equation.
20 + -20 + 0.5e = 25 + -20
Combine like terms: 20 + -20 = 0
0 + 0.5e = 25 + -20
0.5e = 25 + -20
Combine like terms: 25 + -20 = 5
0.5e = 5
Divide each side by '0.5'.
e = 10
Simplifying
e = 10
Answer:
e = 1
Step-by-step explanation:
0.5e + 20 = 25
0.5e = 5
e = 1
You subtract 20 from 25 to get 5. Then you divide 5 by 5 to get e = 1

Given the function h(x) = —~2 – 6x + 17, determine the average rate of change
of the function over the interval – 6 < x < -2.
Answer:
Average Rate of change of given function [tex]h(x)=-x^2-6x+17[/tex] is 2
Step-by-step explanation:
We are given function: [tex]h(x)=-x^2-6x+17[/tex] (considering x is missed)
We need to find average rate of change of the function over the interval [tex]- 6 < x < -2[/tex].
[tex]x_{1} = -6\\x_2 =-2[/tex]
Formula used to find average rate of change is: [tex]Average \ Rate \ of \ Change =\frac{h(x_2)-h(x_1)}{x_2-x1}[/tex]
Finding f(x₁) and f(x₂)
[tex]We \ have \ x_1=-6\\h(x_1)= -x^2-6x+17\\h(x_1)=-(-6)^2-6(-6)+17\\h(x_1)=-36+36+17\\h(x_1)=17[/tex]
[tex]We \ have \ x_2=-2\\h(x_2)=-x^2-6x+17\\h(x_2)=-(-2)^2-6(-2)+17\\h(x_2)=-4+12+17\\h(x_2)=25[/tex]
Putting values in the formula of average rate of change
[tex]Average \ Rate \ of \ Change =\frac{h(x_2)-h(x_1)}{x_2-x1}\\h(x_2)=25, h(x_1)=17, x_1 =-6 \ and \ x_2=-2\\Average \ Rate \ of \ Change =\frac{25-17}{-2-(-6)}\\Average \ Rate \ of \ Change =\frac{8}{4}\\Average \ Rate \ of \ Change =2[/tex]
So, Average Rate of change of given function [tex]h(x)=-x^2-6x+17[/tex] is 2
What is 2M?
M=[3 5]
[-4 0]
Answer:
2M will be:
[tex]2\begin{pmatrix}3&5\\ -4&0\end{pmatrix}=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]
Therefore, the 2nd option is true.
Step-by-step explanation:
Given the matrix
[tex]M=\begin{pmatrix}3&5\\ -4&0\end{pmatrix}[/tex]
Multiplying by 2 will basically be a scalar multiplication.
Therefore, multiply each of the matrix elements by a scalar.
[tex]2M=2\begin{pmatrix}3&5\\ \:-4&0\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}2\cdot \:3&2\cdot \:5\\ 2\left(-4\right)&2\cdot \:0\end{pmatrix}[/tex]
[tex]=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]
Hence, 2M will be:
[tex]2\begin{pmatrix}3&5\\ -4&0\end{pmatrix}=\begin{pmatrix}6&10\\ -8&0\end{pmatrix}[/tex]
Therefore, the 2nd option is true.

For a segment of a radio show , a disc jockey can play 7 records . If there are 9 records to select from , in how many ways can the program for this segment be arranged ?
Answer: 72
Step-by-step explanation:
From the question, we are informed that a disc jockey can play 7 records and that there are 9 records to select from for a particular segment of a radio show.
The number of ways that the program for the segment be arranged will be:
= 9! / 7!
= (9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (7 × 6 × 5 × 4 × 3 × 2 × 1)
= 9 × 8
= 72

Step-by-step explanation:
On a conveyor belt, there can only be two boxes moving at a time. The total weight of the boxes cannot be more than 300 pounds. Let x and y represent the weights of the two boxes on the conveyer belt.
a. Write an inequality that describes the weight limitation in terms of x and y.
b. Two boxes are to be placed on the conveyor below. The first box weighs 175 pounds. What is the maximum weight of the second box?
Answer:
The maximum weight of the second box is 125 pounds. (The box can weight less than 125 pounds, but no more than 125 pounds since the total weight of the boxes cannot be more than 300 pounds.)
Step-by-step explanation:
x+y ≤ 300
175+y ≤ 300
Substract 175 on both sides:
y ≤ 125
The inequality that describes the weight limitation in terms of x and y is -
x + y ≤ 300 and the maximum weight of second box can be 125 pounds.
We have a conveyor belt such that there can only be two boxes moving at a time. The total weight of the boxes cannot be more than 300 pounds.
It is given in the question to assume let x and y represent the weights of the two boxes on the conveyer belt.
We have to find -
a) - inequality that describes the weight limitation in terms of x and y.
b) - If two boxes are to be placed on the conveyor belt and first box weighs 175 pounds then what is the maximum weight of the second box?
What is inequality?Inequality in mathematics is a relation that is used to compare two or more algebraic expressions.
According to the part 'a' of the question -
The inequality that describes the weight limitation in terms of x and y is -
x + y ≤ 300
According to part 'b' of the question -
x = 175 pounds
The maximum weight of second box can be found out by substituting the value of 'x' in inequality in part a.
175 + y ≤ 300
y ≤ 125
Hence, the maximum weight of second box can be 125 pounds.

Answer:
1. ASA
2. SSS and SAS
Step-by-step explanation:
1. We know that two angles are congruent, and the side in between them is congruent, so the postulate we can use is the ASA postulate
2. SSS and SAS. We know that two sides are congruent. We can figure out that AC = AC by the reflexive property so we can use the SSS postulate. We can also use the SAS because two sides are congruent and the angle in between them is congruent too.
