Answer:
a) R = {-11, -2, 7}b) R = {-4, 4, 14}c) R= {-18, -13, -8}d) R = {-6, -5, -1}Step-by-step explanation:
a) g(x)=−3x+1, D={−2, 1, 4}
g(-2) = -3(-2) + 1 = 7g(1) = -3*1 + 1 = -2g(4) = -3*4 + 1 = -11R = {-11, -2, 7}b) f(x)=2x+6, D={−5, −1, 4}
f(-5) = 2(-5) + 6 = -4f(-1) = 2(-1) + 6 = 4f(4) = 2*4 + 6 = 14R = {-4, 4, 14}c) g(x)=5x−3, D={ −3, −2, −1}
g(-3) = 5(-3) - 3 = -18g(-2) = 5(-2) - 3 = -13g(-1) = 5(-1) - 3 = -8R= {-18, -13, -8}d) f(x)=x−4, D={−2, −1, 3}
f(-2) = - 2 -4 = -6f(-1) = -1 - 4= - 5f(3) = 3 - 4 = -1R = {-6, -5, -1}Which of the following equations are equivalent to -2m - 5m - 8 = 3 + (-7) + m?
-7m - 8 = m - 4
-15m = -4m
-8 - 3m = 4 - m
-8 - 7m = -4 + m
m - 4 = -7m - 8
-3m - 8 = 4 - m
Answer: answers are (-7m - 8 = m -4) and m - 4 = -7m -8. Hope this helps :)
Step-by-step explanation:
The expressions equivalent to the given expressions -2m - 5m - 8 = 3 + (-7) + m are (-7m - 8 = m - 4), (-8 - 7m = -4 + m), and (m - 4 = -7m - 8).
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given expression is -2m - 5m - 8 = 3 + (-7) + m. The given expression will be solved as:-
-2m - 5m - 8 = 3 + (-7) + m
-7m - 8 = -4 + m
We can also write the same equation in different ways:-
(-8 - 7m = -4 + m)
(m - 4 = -7m - 8)
Therefore, the expressions equivalent to the given expressions -2m - 5m - 8 = 3 + (-7) + m are (-7m - 8 = m - 4), (-8 - 7m = -4 + m), and (m - 4 = -7m - 8).

What is a linear number equation ? I don’t understand
Answer:
How do you explain a linear equation?
The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. An example of linear equation is y=mx + b. "Linear equation."
Step-by-step explanation:
In mathematics, a linear equation is an equation that may be put in the form where are the variables, and are the coefficients, which are often real numbers. The coefficients may be considered as parameters of the equation, and may be arbitrary expressions, provided they do not contain any of the variables.

A discrete graph is a series of scatter plot points. It means point on graph aren't continuous manner.
A continuous function allows the x-values to be ANY points in the interval, including fractions, decimals, and irrational values. A discrete function allows the x-values to be only certain points in the interval, only integers or whole numbers.

find angles EFG pleaseee
Answer:
50 degrees.
Step-by-step explanation:
Angle FGE = [tex]180-(7x+18)[/tex] because angles on a straight line add up to 180 degrees.
Angle EFG = [tex]180-38-(180-(7x+18))=6x-10[/tex] (Angles in a triangle add up to 180)
[tex]180-38-\left(-7x+162\right)=6x-10[/tex]
[tex]180-38+7x-162=6x-10[/tex]
[tex]7x-20=6x-10[/tex]
Add 20 to both sides:
[tex]7x-20+20=6x-10+20[/tex]
[tex]7x=6x+10[/tex]
Subtract 6x from both sides:
[tex]7x-6x=6x+10-6x[/tex]
[tex]x=10[/tex]
Angle [tex]EFG=6x-10=6(10)-10=60-10=50[/tex]

A (2, -1.5)
B (-2, 1.5)
C (2, 1.5)
D (1.5, 2)
Answer:
C.
Step-by-step explanation:
The midpoint of the final image is (2, 1.5).
What is the scale factor?Scale Factor is used to scale shapes in different dimensions. In geometry, we learn about different geometrical shapes both two-dimension and three-dimension.
Segment JK has endpoints J(2,4) and K(6,2).
You dilate the segment using a dilation centered at the origin with a scale factor of 1/2 and then reflect the image on the x-axis.
The co-ordinate of the final image is;
[tex]\rm J' = Scale \ factor (J) = \dfrac{1}{2} (2, \ 4) = (1, \ 2)\\\\K' = Scale \ factor (K) = \dfrac{1}{2} (6, \ 2) = (3, \ 1)\\[/tex]
The midpoint of the final image is;
[tex]\rm Midpoint \ of \ J'= \left (\dfrac{1+3}{2} \right )= \left (\dfrac{4}{2} \right )=2\\\\ Midpoint \ of \ K'= \left (\dfrac{2+1}{2} \right )= \left (\dfrac{3}{2} \right )=1.5[/tex]

One month, Ruby worked 7 hours more than Isaac, and George worked 3 times as many hours as Ruby. Together they worked 150 hours. How many total hours did they work? Send
Answer:
Issac worked 24.4 hrs, Ruby worked 31.4 hrs, and George worked 94.2 hours
Step-by-step explanation:
x= hours worked
Issac= x Ruby= (x+7) George= 3(x+7)
x+(x+7)+3(x+7) = 150 [distribute 3 to (x+7)]
x+(x+7)+(3x+21) = 150 [add from left to right]
5x+28 = 150 [subtract 28 from both sides]
5x = 122 [divide both sides by 5]
x=24.4
Now plug the x value back into Issac, Ruby, and George's equations:
Issac=x=24.4
Ruby=x+7=31.4
George=3(x+7)=94.2
Double check by adding all their work hours together

An angle measures 44° less than the measure of its complementary angle. What is the measure of each angle?
a+b=90°
a=b+44°
b+44°+b=90°
2b+44°=90°
2b=90°-44°
2b=46°
b=23°
a=23°+44°
a=67°
The measure of each angle is 23° and 67°.
What is Angle?Angle is defined as the figure formed by the meeting of two lines or rays at a common point.
Complementary angles are those angle whose angle measures sum up to 90°.
Given that two angles are complementary and one of the angle's measure is 44° less than the measure of other one.
Let x be the measure of first angle.
Then x - 44 is the measure of the other angle.
x + (x - 44) = 90°
2x - 44 = 90
2x = 90 + 44
2x = 134
x = 134 / 2
x = 67
One of the measure of angle is 67°.
Measure of other angle = x - 44 = 67 - 44 = 23°
Hence the angle measures are 23° and 67°.

Step-by-step explanation:
Add '-24' to each side of the equation.
24 + -24 + 6n = -18 + -24
Combine like terms: 24 + -24 = 0
0 + 6n = -18 + -24

Combine like terms: -18 + -24 = -42
6n = -42
Divide each side by '6'.

solve for x: x-17 =-29
Answer:
x = - 12
Step-by-step explanation:
Given
x - 17 = - 29 ( add 17 to both sides )
x = - 12
Answer:
x=12
Step-by-step explanation:
when performing x-17=-29, you first have to do the inverse of -17 in order to isolate x. Therefore, your would +17 to the left side of the equation (x-17) resulting in only the letter x being left on that side. Then you would have to add the 17 to the other side of the equation resulting in x=-29+17 which will then result in x=12.

X+ 3y = 9
2x+ y = -2
Solve for x and y
Answer:
(-3, 4)
Step-by-step explanation:
hey there,
< From the first equation, let's find x.
x + 3y = 9
x = 9-3y (I hope you understand how that works )
Next, we can substitute our equation that equals to x into the second equation.
2x + y = -2
2(9-3y) + y = -2 (I substituted "x" in "2x" with (9-3y))
Now, let's solve.
2(9-3y) + y = -2
18 - 6y + y = -2
-5y = -20
y = 4
Now that we have found what y is equal to, we can find x too. In the beginning we found that x = 9-3y so x = 9-3(4) = -3 >

The sum of the angle measures of the polygon is 540°. Write and solve an equation to find the value of x. Problems- 85 degrees 5x degrees 5x degrees 5x+5 degrees 5x-10 degrees PLEASE HELP!
Answer:
The measure of x is 23 degrees
Step-by-step explanation:
Here, given the values of the angles of a polygon and the total of these angles, we want to find the value of the variable x attached to these angles;
Mathematically;
85 + 5x + 5x + 5x + 5 + 5x -10 = 540
85 + 5 -10 + 5x + 5x + 5x + 5x = 540
80 + 20x = 540
20x = 540-80
20x = 460
x = 460/20
x = 23 degrees
