3 (n+1) - 5 = 3n - 1
I need help with this question
Answer:
There are no solutions.
Step-by-step explanation:
3(n+1) = 3n+3.
3n+3-5 = 3n-2.
3n-2 doesn't equal 3n-1, so there are no solutions.

Answer:
If your Simplifying well the answer would be 9/20
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 18 and 40 is 2
Divide both the numerator and denominator by the GCD
18 ÷ 2
40 ÷ 2
Reduced fraction:
9
20
Therefore, 18/40 simplified to lowest terms is 9/20.

Parallel lines have the same slope, while perpendicular lines have an opposite reciprocal slope.
Line 1:
-5y = 3x + 7
y = -3/5x - 7/5
Line 2:
y = -5/3x + 8
Line 3:
6x - 10y = -4
-10y = -6x - 4
y = 3/5x + 2/5
Line 1 and Line 2 are neither perpendicular nor parallel. While their slopes are reciprocals of each other, the signs are not opposite (both are negative).
Line 1 and Line 3 are neither perpendicular nor parallel. While the slope itself is the same, the signs are different.
Line 2 and Line 3 are perpendicular. Their slopes are opposite reciprocals of each other.

Solve for b in the literal equation a+ b+ c= 180
Answer:
b = 180 - a - c
Step-by-step explanation:
To solve for b given the literal equation, a + b + c = 180:
Subtract a and c from both sides:
a + b + c = 180
a - a + b + c - c = 180 - a - c
b = 180 - a - c

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:
y > 3x + 10
y<-
Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area. (6 points)
Part B: Is the point (8, 10) included in the solution area for the system? Justify your answer mathematically. (4 points)
(10 points)
Answer:
Step-by-step explanation:
y > 3x + 10
y < -3x - 1
Part A:You'd graph the given systems of linear inequalities the same way as you graph the linear equations.
To graph y > 3x + 10, plot the y-intercept, (0, 10), then use the slope, m = 3 (rise 3, run 1), to plot other points on the graph. Use a dashed line (because of the ">" symbol).
Follow the same steps for the other linear inequality. Plot the y-intercept, (0, -1), then use the slope, m = -3 (down 3, run 1) to plot other points. Use a dashed line (because of the "<" symbol).
Pick a test point on either side of the boundary line and plug it into the original problem. This will help determine which side of the boundary line is the solution. Plug in a test point that is not on the boundary line.
Use the point of origin, (0, 0) as the test point. Plug in these values into the given systems of linear inequalities to see whether it will provide a true statement.
y > 3x + 10
0 > 3(0) + 10
0 > 0 + 10
0 > 10 (False statement).
y < -3x - 1
0 < -3(0) - 1
0 < 0 - 1
0 < -1 (false statement).
Since the point of origin provided a false statement to the given systems of linear inequalities, you must shade the half-plane region where it doesn't contain the test point.
Part B:
You'll do the same process as what I've done for the test point. Plug in the values of (8, 10) into the given systems of linear inequalities. If it provides a false statement, then it means that it is not a solution to the system.
y > 3x + 10
10 > 3(8) + 10
10 > 24 + 10
10 > 34 (False statement).
y < -3x - 1
10 < -3(8) - 1
10 < -24 - 1
10 < -25 (false statement).
Therefore, (8, 10) is not a solution to the system.

Answer:
x = 36.9°
Step-by-step explanation:
We need to find out what sides of the triangle we have, so we can find the formula for the missing angle, x.
We have been given the opposite and hypotenuse so we are using sine
SOH, CAH, TOA
sin (x) = opp ÷ hyp
Substitute in the values
sin (x) = 9 ÷ 15
Simplify
sin (x) = 0.6
Rearrange to find x
x = sin^-1(0.6) - Type this into your calculator
sin^-1 is the inverse or opposite of sinx = 36.8698... ≈ 36.9°

Emma has just started a new sales job. She makes $20 an hour. On top of her hourly wages, she’ll be paid a commission of 15% on all sales she makes. Use this information to answer the following questions.
Part A
Question
Which equation in the form y = mx + cs models Emma’s situation?
y = 20x + 0.15
y = 20x + 15
y = 20x + 0.15s
y = 20x + 15s
Answer:
y = 20x + 0.15s
Step-by-step explanation:
Shew makes $20 par hour, so for x hours, she makes 20x.
She makes 15% commission on the sales, s. 15% = 0.15,so for the sales, s, she makes 15% * s = 0.15s.
The total she makes is 20x + 0.15s
Answer: y = 20x + 0.15s
The equation in the form y = mx + cs models Emma’s situation is
y = 20x + 0.15s
Shew makes $20 par hour, so for x hours, she makes 20x.
What is the slope-intercept form of the line?
The slope-intercept of the line y= mx+c
Where y co-ordinate
x- x co-ordinate
m=slope of the given line
C-y intercept.
She makes 15% commission on the sales, s. 15% = 0.15,
So for the sales, she makes
15% * s = 0.15s.
The total she makes is 20x + 0.15s
y = 20x + 0.15s

Step-by-step explanation:
Solve 4(x−5)=6x. You must SHOW EACH STEP for full credit.
Answer:
x = − 10
Step-by-step explanation:
Let's solve your equation step-by-step.
4 ( x − 5 ) = 6x
Step 1: Simplify both sides of the equation.
4 ( x − 5 ) = 6x
( 4 ) ( x ) + ( 4 ) ( − 5 ) = 6x ( Distribute )
4x + − 20 = 6x
4x − 20 = 6x
Step 2: Subtract 6x from both sides.
4x − 20 − 6x = 6x − 6x
− 2x − 20 = 0
Step 3: Add 20 to both sides.
− 2x − 20 + 20 = 0 + 20 − 2x = 20
Step 4: Divide both sides by -2.
− 2x / − 2 = 20 / − 2
x = − 10

b. What is the
scale factor that
takes Figure 2.
to Figure 1?
D
Figure 1
Figure 2
S
The quadrilaterals are similar and are related by a scale factor, taken from
a specific location, that maps the points on one figure to the other.
a. The scale factor that takes Figure 1 to Figure 2, is 3
b. The scale factor that takes Figure 2 to Figure 1 is [tex]\dfrac{1}{3}[/tex]
Reasons:
From the question, we have that Figure 1 is a scaled copy of Figure 2, therefore;
Let ABCD represent Figure 1, we have;
ABCD ~ PQRS
Length of [tex]\overline{AD}[/tex] = √(2² + 3²) = √(13)
Length of [tex]\overline{PS}[/tex] = √(6² + 9²) = √(117) = √(9 × 13) = 3·√(13)
Therefore;
a. The scale factor that takes Figure 1 to Figure 2, SF₁₂, is therefore;
[tex]SF_{12} = \mathbf{\dfrac{\overline{PS}}{\overline{AD}}}[/tex]
Which gives;
[tex]SF_{12} = \dfrac{3 \cdot \sqrt{13} }{\sqrt{13} } = 3[/tex]
The scale factor that takes Figure 1 to Figure 2, SF₁₂ = 3
(3 times the lengths of Figure 1 gives the lengths on Figure 2)
b. The scale factor that takes Figure 2 to Figure 1, SF₂₁, is given as follows;
[tex]SF_{21} = \mathbf{\dfrac{\overline{AD}}{\overline{PS}}}[/tex]
Which give;
[tex]SF_{21} = \dfrac{\sqrt{13} }{3 \cdot \sqrt{13} } = \mathbf{\dfrac{1}{3}}[/tex]
The scale factor that takes Figure 2 to Figure 1, SF₂₁ is [tex]\underline{\dfrac{1}{3}}[/tex]
