Which of the graphs below represents the equation 3x - 2y = -12
Answer:
Graph B
Step-by-step explanation:
First you solve them which will give you,
X-intercept = (-4,0)
Y-intercept = (0,6)
Slope 3/2x
equation for this: y = 3/2x + 6
So graph B is the only option like this.

Answer: The length of JK is 10.5 m
Step-by-step explanation:
Find the circumference C= dπ
C = 12π
C= 37.7
There are 360 degrees in a circle's circumference, so you can find the length of the arc by using the ratio of the arc to the whole circumference.
Multiply the Circumference by 100/360 (or 5/18 × 37.7)
The arc is 10.5 m

Answer:
y=(1/2)x+3
Step-by-step explanation:
We can see that the slope is 1/2 because for every 1 unit y goes up, you move 2 units in the x direction. Then we can see that the y intercept is 3.
If we plug in these values to our equation for a line (y=mx+b), where m is the slope and b is the y-intercept, we get:
y=(1/2)x+3 or y=.5x+3

Answer:
48°
Step-by-step explanation:
The m in front of the angle notation refers to the measure of the angle labeled A, B and C (with vertex at B)
Two Angles are Supplementary when they add up to 180 degrees.
HENCE,
∠A + ∠B =180 (given)
⇒4x - 16 +8x + 4 = 180°
⇒12x - 12 = 180°
⇒12x = 192
⇒x = 16 ----1
substituting eq1 in ∠A,
=> 4(16) -16
=> 64 - 16
=> ∠A = 48°
Answer:
48
Step-by-step explanation:
The definition of supplementary means that the two angles add up to 180. so you set both expressions up to where they add to 180. like this
4x-16+8x+4=180
combine like terms
12x-12=180
12x=192
divide to get x
x=16.
You need the measure of angle A so you plug it back in
4(16)-16
64-16
48 is the measure of angle A, and since these angles are supplementary, that means angle B is 132
x to the forth power ÷ 3+9 when x=3
Answer:
36
Step-by-step explanation:
Ok, so the expression we are given is [tex]x^{4}[/tex] ÷ 3 + 9.
We know that x = 3, so we need to substitute 3 in as x.
So, now the expression looks like [tex]3^{4}[/tex] ÷ 3 + 9.
Now we can solve this expression.
First we need to figure out what [tex]3^{4}[/tex] is equal to.
1. [tex]3^{4}[/tex] = 81
We're left with 81 ÷ 3 + 9.
Next, we need to divide our 81 by our 3.
2. 81 ÷ 3 = 27
Our new expression is 27 + 9.
Last, we need to add our 27 and our 9 together.
3. 27 + 9 = 36
Our answer is 36.
So [tex]x^{4}[/tex] ÷ 3 + 9 when x = 3 is 36.

Your salary is $65,788. If you work fifty 40-hour weeks in a year, what is your hourly wage?
Answer:
$31.63/hr
Step-by-step explanation:
Given parameters:
Yearly salary = $65788
Number hours worked per week = 40hrs
Unknown:
Hourly wage = ?
Solution:
The hourly wage is found by dividing the yearly salary by the total number of hours worked per year.
There are 52 weeks in a year;
Number of hours worked per year = 52 x 40 = 2080hrs
Hourly wage per year = [tex]\frac{65788}{2080}[/tex] = $31.63/hr

m = 0.28 or 0.29
You have a rectangle with the perimeter of 150 cm. One side length is
represented by 2x+4. The other side is 30 cm. What is the value of the side length represented by 2x+4?
side length represented by 2x+4?*
Answer:
x=20.5
Step-by-step explanation:
Perimeter of rectangle = 2(L+B)
L- Length and B - Breadth
150 = 2( 2x+4 +30)
150÷2 = 2x + 34
75 = 2x + 34
2x = 75 -34
2x = 41
x = 20.5

What is the image of the point (8,-9) after a rotation of 180° counterclockwise
about the origin?
Answer:
(-8, 9)
Step-by-step explanation:
A 180 degree rotation is:
[tex](x,y)\rightarrow(-x,-y)[/tex]
Apply the rule to the point given:
[tex](8,-9)\rightarrow\boxed{(-8,9)}[/tex]
Hope this helps.
The image of the point (8,-9) after a rotation of 180° counterclockwise
about the origin is (-8, 9).
How does rotation by 90 degrees changes coordinates of a point if rotation is with respect to origin?Let the point be having coordinates (x,y).
Case 1: If the point is in first quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
For points on axes, You can take that point in any of the two surrounding quadrants. Example, if the point is on positive x axis, then it can taken as of first quadrant or fourth quadrant.
It is noted that for a 180 degree rotation the points move from (x, y) to (-x, -y)
A 180 degree rotation is:
(x, -y) --- (-x, y)
Apply the rule to the point given:
(8,-9) --- (-8, 9)
Hence, The image of the point (8,-9) after a rotation of 180° counterclockwise about the origin is (-8, 9).

△MNP ≅ △TUS. Use the picture below to solve for the following: x, y, and m∠N.
Answer:
x = 32
y = 51
m∠N = 14°
Step-by-step explanation:
Given:
ΔMNP ≅ ΔTUS
By the property of similarity,
MN ≅ TU, NP ≅ US and MP ≅ TS
m∠M = m∠T = 142°,
m∠N = m∠U = (2x - 50)°
m∠P = m∠S = 24°
Since, m∠N = [180°- (m∠M + m∠P)]
(2x - 50) = 180 - (142 + 24)
2x - 50 = 14
2x = 64 ⇒ x = 32
Since, NP = US,
2x - y = 13
2(32) - y = 13
64 - y = 13
y = 51
m∠N = 180° - (142 + 24)°
= 14°
The value is x = 32 , y = 51 , and m∠N = 14°
Given that
ΔMNP ≅ ΔTUS.Based on the above information, the calculation is as follows:
Here we use the property of similarity,
So,
MN ≅ TU, NP ≅ US , and MP ≅ TS
Based on this
m∠M = m∠T = 142°,
m∠N = m∠U = (2x - 50)°
m∠P = m∠S = 24°
As
m∠N = [180°- (m∠M + m∠P)]
(2x - 50) = 180 - (142 + 24)
2x - 50 = 14
2x = 64
x = 32
As, NP = US,
2x - y = 13
2(32) - y = 13
64 - y = 13
y = 51
m∠N = 180° - (142 + 24)°
= 14°
Therefore the above are the answers.

Answer:
[tex]m\angle CAB=65^\circ[/tex]
Step-by-step explanation:
Angles and Lines
It's convenient to recall two basic principles of angles:
The sum of internal angles in a triangle is 180°
Two linear angles are supplementary, i.e. they sum 180°.
Angles ABC and CBD are linear. Since we know the measure of angle CBD, thus the measure of angle ABC is 180°-6x.
Now focus on the triangle. The sum of its internal angles is:
x + 40 + 3x + 10 + 180 - 6x = 180
Simplifying:
-2x + 230 = 180
Subtracting 230:
-2x = -50
Dividing by -2:
x = -50 / (-2) = 25
x = 25°
Now find the measure of angle CAB
[tex]m\angle CAB=x+40=25+40=65[/tex]
