Answer:
B. 4
Step-by-step explanation:
Determine the constant of variation for the direct variation given.
(0, 0), (3, 12), (9, 36)
A. 3
B. 4
C.12
Direct variation is given by:
y = kx
Where,
k = constant of variation
(3, 12)
x = 3; y = 12
y = kx
12 = k*3
12 = 3k
k = 12 / 3
k = 4
(9, 36)
x = 9; y = 36
y = kx
36 = k * 9
36 = 9k
k = 36 / 9
= 4
k = 4
Constant of the variation = 4

Describe and correct the error in finding the intercepts.
Example:
The intercept is not at (8, 2) because... Instead, it
should be...
Answer:
The x=8 is only for the x interecept, and the x-intercept is (8,0). You assume y to be 0 then you say it's 2, that is incorrect. x and y interecepts should not be combined. The correct x-intercept and y-intercept are (8,0) and (0,2) respectively
(2.0 x 10-3) (3.5 x 10)
What is the value of the expression?
Answer:
595
Step-by-step explanation:
SOLUTION STEPS
(2.0×10−3)(3.5×10)
Multiply 2 and 10 to get 20.
(20−3)×3.5×10
Subtract 3 from 20 to get 17.
17×3.5×10
Multiply 17 and 3.5 to get 59.5.
59.5×10
Multiply 59.5 and 10 to get 595.

Johnny and Dustin both went bowling last weekend, but not together. Johnny went during open bowling time, paying $13 for shoe rental and $3 per hour. Dustin went on family night, when each hour was $4 and shoe rental was $3. As it turned out, they played for the same number of hours and spent the same amount. How much did each one spend? How many hours did each one bowl?
Answer:
10 hours
$43
Step-by-step explanation:
Given that:
Jonny:
Shoe rental = $13
Fee per hour = $3
Dustin :
Shoe rental = $3
Fee per hour = $4
Number of hours bowled is the same
Let number of hours bowled = x
$13 + 3x = $3 + 4x
3x - 4x = $3 - $13
-x = - 10
x = 10
Number of hours each bowled = 10
Amount spent :
Jonny:
$13 + 3x = $13 + $3(10) = $13 + $30 = $43
Dustin :
$3 + 4x = $3 + $4(10) = $3 + $40 = $43
Shen and David each washed a car.
• Shen spent 5 minutes washing his car for every 2
• Each boy started washing his car at 4:00 4.
• David finished washing his car at 4:30 PM.
At what time did Shen finish washing his car?
Step-by-step explanation:
Shen time= 5 min (David time/2 minutes)
David time= 4:30-4:00= 30 minutes
Shren time=5(30/2)=5(15)= 75 minutes
Identify an equation in point-slope form for the line parallel to y+-2/3x+8 that passes through (4, -5).
Step-by-step explanation:
Line parallel to the line y = -2/3 x + 8 also has the slope -2/3.
Since the line passes through (4, -5), we have (x - 4) written on the right side and (y + 5) on the left side.
Hence the equation is y + 5 = -2/3 * (x - 4). (B)

Why are inverse operations and
properties of equality important when solving
equations? Explain.
Answer:
An inverse operation is two operations that undo each other e.g. addition and subtraction or multiplication and division. You can perform the same inverse operation on each side of an equivalent equation without changing the equality. This gives us a couple of properties that hold true for all equations.

In an isosceles trapezoid, how do you prove the base angles are congruent?
Answer: Well there's a geometry definition stating that the two angles are equal.
But ig i can try to make a proof.
First make a perpendicular bisector from the vertex to the bottom splitting the bottom side in half.
Now because of LL theorem, and the reflexive property, the two triangles are equal.
Now using cpctc, the two angles are also equal.

Answer:
A 33 degrees
Step-by-step explanation:
[tex]x \degree = 180 \degree - (23 \degree + 124 \degree) \\ \\ x \degree = 180 \degree - 147 \degree\\ \\ x \degree = 33 \degree \\ \\ x = 33[/tex]
Answer:
A) 33
Step-by-step explanation:
the angles of a triangle always add up to 180.
124 + 23 + x = 180
combine like terms
147 + x = 180
147 + x - 147 = 180 - 147
x = 180 - 147
x = 33

ABCD is a rhombus.
Find each angle.
Reason:
Plz answer ASAP, thank you
Answer:
Step-by-step explanation:
I sympathize. The question is not very clear: you don't know what A and B really are (I mean which vertex).
However it is a rhombus, and you are to assume that B follows A. So put A anywhere and make B follow it. They are supplementary which means they add to 180 degrees. All rhombi have that property.
A + B = 180
A/B = 2/1
Cross Multiply the second equation
A = 2*B
Put 2B into the first equation.
2B + B = 180 Combine the left terms
3B = 180 Divide both sides of the equation by 3
B = 180 / 3
B = 60
B = 60
A = 180 - 60 = 120
Label the two acute angles as 60 and the two obtuse angles as 120.
Acute: means less than 90
Obtuse: means more than 90

(triangles) if FGH= QRS, find the measure of
Answer:
Option (4)
Step-by-step explanation:
From the picture attached,
ΔFGH ≅ ΔQRS
Therefore, ∠F ≅ ∠Q
m∠F = m∠Q
(2x + 10)° = (3x + 1)°
3x - 2x = 10 - 1
x = 9
m∠Q = (3x + 1)°
= 27 + 1
= 28°
Option (4) will be the correct option.
Please help .........
Answer:
Step-by-step explanation:
1. ST > MN (ST is NOT congruent to MN)
2. BA > BC (not congruent)
3. m∠L < m∠P and m∠T < m∠R
4. m∠A < m∠B and m∠C
m∠D and m∠E > m∠F

Answer:
D.) This system has no solutions (The one you chose is correct)
Step-by-step explanation:
y = 8x + 9
-8x + y = -1
-8x + y = -1
y = 8x - 1
These two lines will also never meet as the slope are both 8, but the y-intercept is different, to check, look at the graph below.
Answer:
You're right, the system has no solutions
Step-by-step explanation:
y=8x+9
-8x+y=-1
-8x+y=-1
y=-1+8x
8x+9=1+8x
9≠1
The system has no solutions
