Answer:
2 (2 x - 3)
Step-by-step explanation:
Simplify the following:
2 (4 x - 3) - 3×3 x + 5 x
-3×3 = -9:
2 (4 x - 3) + -9 x + 5 x
Grouping like terms, 2 (4 x - 3) - 9 x + 5 x = 2 (4 x - 3) + (5 x - 9 x):
2 (4 x - 3) + (5 x - 9 x)
5 x - 9 x = -4 x:
2 (4 x - 3) + -4 x
2 (4 x - 3) = 8 x - 6:
8 x - 6 - 4 x
Grouping like terms, 8 x - 4 x - 6 = (8 x - 4 x) - 6:
(8 x - 4 x) - 6
8 x - 4 x = 4 x:
4 x - 6
Factor 2 out of 4 x - 6:
Answer: 2 (2 x - 3)

Answer:
-5 is the y intercept
Step-by-step explanation:
Hi! Need help rly quick ☺️, will mark brainilest!!
Answer:
A.
Step-by-step explanation:
Subtract -4x on both sides to get to -2y=-4x-8, then you should divide -2 into both sides to get to the slope of y=2x+4 since two negatives would equal to a positive when dividing and multiplying. Because the slope is positive, it is safe to assume that the first two options A and B are the best options due to their slopes being positive and going up. The y-intercept is 4 which makes the answer A because on 0 it is on the positive side.

Answer:
The length of the body is 45.
Step-by-step explanation:
The violin and bass have an equal ratio, to find the ratio find the two given lengths and divide them, 72 ÷ 24 = 3. So the ratio is 3:1. To find the body of the bass you just have to do 15 × 3. Which is 45.

I don't get this find all missing angles what does it mean how do I do it
First, you can find angle 1 by using the triangle angle formula, stating that all angles add up to 180 deg. Thus, angle 1 is equal to 180-72-57= 51 deg.
Next, you can find angle 2 by using the right angle shown. This means that angle 2 plus 72 deg = 90 deg. Thus, angle 2 is equal to 90-72= 18 deg.
For angle 3, notice that it is bordering the other angle on a straight line. A straight line is equal to 180 deg. This means that angle 3 + 57 deg = 180 deg. Thus, angle 3 is equal to 180-57= 123 deg.
Angle 4 can be found by using the triangle angle formula used for angle 1. In this case, angle 2+3+4 will equal 180 deg. Thus, angle 4 is equal to 180-18-123= 29 deg.
Answer:
1= 51
2= 18
3= 123
4= 39
Step-by-step explanation:
First you must know that all triangles equal 180. From there you can add and subtract the known numbers to get your answers. For example with angle 1, because you are give 72 and 57 you must add them together to get 129 then subtract that from 180 to get 51. You can do similar steps for all the angles to receive the answers.

Solve each equation. Check your solution.
a - 5 = -12
Answer:
A = -7
Step-by-step explanation:
Isolate the variable by adding 5 to each side. This becomes A = -7. To check your work plug -7 in for A.
-7 - 5 = -12
-12 = -12
This is true so -7 is the correct answer.

The given triangles are not similar.
What is similarity of triangles?Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.
Given a figure of two triangles, ΔWXT and ΔYXZ
Here,
28/35 ≠ 30/38
WX/YX ≠ XT/XZ
We can conclude that, the corresponding sides are not in common ratio, so triangles are not similar.
Hence, The given triangles are not similar.

A retail store makes k% profit on the selling price. What is the least integer value of k that will enable the store to make a profit of at least 30% of the cost of the item?
Answer: 10
Step-by-step explanation:
The store wants to make a 20% profit:
Multiply the cost of the toy by 1.20 ( cost plus 20%).
6.25 x 1.20 = $7.50
This means when the toy is sold at 25% off, it needs to be $7.50 to make the 20% profit.
When the item is 25% off, that means it would sell for 75% of the original price.
Now to find what the price needs to be before the 25% off divide the profit price by 75%
7.50 / 0.75 = $10
K = $10

Answer:
Y=109 X=31
Step-by-step explanation:
Alright, so the angles that you have to find the values for make up 180 degrees. Since you have 71 degrees on the bottom, and according to a certain theorem I forgot about, that means that the angles you're solving for equal 109 degrees.
X= 31 because 4 x 31 = 124 and then 124 - 15 equals 109
Answer and Step-by-step explanation:
We are told that l and k are parallel (which is shown with the || symbol).
Line n therefore, is a transversal (a line that intersects two parallel lines).
We are now told to find y and x.
Since we know the lines are parallel, we can use the vertical angles theorem to say that y is equal to 4x - 15.
With angle 71, we can say that the angle that is to the left of (4x - 15) is also 71. When these two are added together, they equal 180. So let's do that.
71 + 4x - 15 = 180
Subtract 71, add 15, then divide by 4.
4x - 15 = 109
4x = 124
x = 31
31 is equal to x.
Now, we plug it into the equation so that it will equal to y.
4(31) - 15 = y
124 - 15 = y
y = 109
109 is equal to y.
We can verify this by using the supplementary angles theorem for y and 71, when 71 is above y. When y and 71 is added together, they add up to 180. So, 180 - 71 is equal to 109, which is y.
31 is equal to x.
109 is equal to y.

whats the average rate of change from x = - 3 to x = 5
Answer:
0
Step-by-step explanation:
Average rate of change from x = -3 to x = 5.
When x = -3, y = -1. That is f(-3) = -1
When x = 5, y = -1, That is f(5) = -1
Average rate of change = [tex] \frac{f(b) - f(a)}{b - a} [/tex]
Where,
[tex] a = -3, f(a) = -1 [/tex]
[tex] b = 5, f(b) = -1 [/tex]
Plug in the values into the equation:
[tex] = \frac{-1 - (-1)}{6 -(-3)} [/tex]
[tex] = \frac{0}{8} [/tex]
[tex] = 0 [/tex]
Average rate of change = 0
