Given that you have 2 parallel lines cut by a transversal, what is the measure of angle 2?
Step-by-step explanation:
angle 2 = 2x + 10 deg (corresponding angles) or 180 - 4x + 46 deg (angles on a straight line are supplementary)
therefore,
2x + 10 = 226 - 4x
6x = 216
x = 36
hence,
angle 2 = 2(36) + 10 = 82deg

Which is the correct description of the transformation?
A rotation 180° clockwise
b
Reflection over the x-axis
c
Translation 5 units left and 2 units down
d
Translation 10 units left and 4 units down
Answer: You're answer to you question would be D
Step-by-step explanation:
The correct description of the transformation translation 10 units left and 4 units down. The correct option is D.
What is transformation?The transformation can be defined as the introduction of a new set of mathematical coordinates that are declared to be different functions of the original coordinates.
Given the per-image and image of different points. Now, if we look at the coordinates of the A and A', then it can be observed that if 10 units is deducted from the x-coordinate of A, then the x-coordinate of A' will be the result.
Similarly, if 4 units is deducted from the y-coordinate of A, then the y-coordinate of A' will be the result.
Further, it is known that reducing n units from x-coordinate means that the point is shifted left by n units. Also, if p units are deducted form the y-coordinate then the point is shifted p units down.
Hence, the correct description of the transformation translation 10 units left and 4 units down.

hector and alex traded video games. alex gave hector one fourth of his video games in exchange for 6 video games. then he sold 3 video games and gave 2 video games to gis brother. alex enbed up with 16 video games. how many video games did alex have when he started?
Answer:
20 games
Step-by-step explanation:
Lets work backwards; *Adding what he gave away or lost*
-Alex started with 16 video games
-Add the games gave to his brother (+2)
-Add the games he sold (+3)
-The number is 3/4 of his games
-Subtract the games he traded with hector (-1/4)
Equation: 16+2+3-6= 3/4 X (variable) *You can choose other than X*
21-6 = 15
15 = 3/4
Take the reciprical of 3/4 which is 4/3 and multiply it by both sides
4/3 x 15 = 3/4 x 4/3
4/3 X 15 = 20!

Nerissa paid a total of $8 for 4 packs of pencils she purchased from the convenience store. Let p represent the cost of one pack of pencils.
Which equation shows an equality between two different ways of expressing the cost for all the pencils?
A. 8 = 4p
B. 8 = 4/p
C. 8 = 4 + p
D. 8 = 4 – p
==================================================
Explanation:
p is a placeholder for a number. Think of it like a box where a number goes inside.
In this case, p is the price of one pack of pencils.
We can use a proportion to help set up an equation
(4 packs)/(8 dollars) = (1 pack)/(p dollars)
4p = 8*1 ... cross multiply
4p = 8
8 = 4p which points to choice A as the answer.
---------------------------
Alternative method:
4 packs = 8 dollars
1 pack = p dollars
Multiply both sides of the second equation by 4 and you'll get
4 packs = 4p dollars
Then replace the "4 packs" on the left hand side with "8 dollars"
8 dollars = 4p dollars
that turns into
8 = 4p
--------------------------
Yet another method:
We know it's $8 for 4 packs. This must mean it is 8/4 = 2 dollars per pack.
If p is the cost of one pack, then p = 2.
Now plug p = 2 into each of the four answer choices. You should find that only 8 = 4p results in a true equation.
Choice B is false because 8 = 4/p turns into 8 = 4/2 and that becomes 8 = 2, which is a false equation. Choices C and D are similar stories.

The answer is A

If C=24, what values of A and B complete Ax+By=C for each graph? Write the standard form for each equation.
For the graph in part a, the value for A is =
and the value for B is =
Answer:
Step-by-step explanation:
For graph (a),
Let the equation of the line is,
Ax + By = C
For the line passing through (4, 0) and C = 24,
4A + B(0) = 24
4A = 24
A = 6
For a point (0, -3) lying on this line,
A(0) + B(-3) = 24
-3B = 24
B = -8
Therefore, equation of the line will be,
6A - 8B = 24
3A - 4B = 12
b). If the equation of the given line is,
Ax + By = 24
For a point (3, 0) lying on the line,
3A + B(0) = 24
A = 8
For a point (0, 2) lying on the line,
A(0) + 2B = 24
2B = 24
B = 12
Therefore, equation of the given line will be,
8A + 12B = 24
2A + 3B = 6

What percent of 40 is 20?
Answer:
8
Step-by-step explanation:
When doing these types of problems, we convert the percent to a decimal. In this case,
40%=0.4
0.4*20=8
Answer:
200%
Step-by-step explanation:
20 = 100% (in this case)
40 = 200% (because you multiply both sides to get 40)
Therefore, 40 is 200% of 20.

What is the cost of each item? What is the subtotal? What is the tax? What is the total paid? Shoes: $49.99 (normally) they are on sale for 25% off Jacket: $137.99 (normally) it is on sale for 33% off Pack of Cookies: $4.49 7.3% Sales Tax What is the cost of each item? What is the subtotal? What is the tax? What is the total paid?
Answer:
Cost of shoes = $37.4925
Cost of jacket = $92.4533
Tax = $9.81
Total paid = $144.2458
Step-by-step explanation:
Normal price of shoes = $49.99
Discount = 25%
Discounted price:
[tex]\$49.99 - \$49.99\times \dfrac{25}{100} = \$37.4925[/tex]
Normal price of jacket = $137.99
Discount = 33%
Discounted price:
[tex]\$137.99 - \$137.99\times \dfrac{33}{100} = \$92.4533[/tex]
Price of pack of cookies = $4.49
No discount on cookies as per question statement.
Total amount without tax = $37.4925 + $92.4533 + $4.49 = $134.4358
Sales Tax = 7.3% of total amount without tax = 7.3% [tex]\times[/tex] $134.4358 = $9.81
Total paid = $134.4358 + $9.81 = $144.2458

The radius of the cone is 7 in and y = 25 in. What is the volume of the cone in terms of π? A cone with a right triangle formed from its dimensions; the value of the height is h, and the value of the slant height is y; the height x and the radius form a right angle at the center of the cone.
Answer:
142.1π in³
Step-by-step explanation:
Given that:
The radius (r) = 7 in
The slant height (y) = 25 in
Then the height (x) can be determined by using the Pythagoras rule:
y² = x² + r²
25² = x² + 7²
125 = x² + 49
125 - 49 = x²
x² = 76
x = √76
x = 8.7
The formula for the volume of a cone is;
= 1/3 πr²h
where;
height(h) is calculated as "x" from above = 8.7
Then;
= 1/3 × π × (7 in)² × 8.7 in
= 142.1π in³
