Step-by-step explanation:
Step 1: Write equation
9 + 3x - 5x = 4x - 3x
Step 2: Solve for x

Explain how you can use SSS, SAS, ASA, OR AAS with the definition of congruence to prove the statement true
Answers
Answer:
D, AAS.
Step-by-step explanation:
So basically the a's and s' mean angle and side. this means that if there is a line on both of the triangles on one side this means that those sides of the triangle are congruent. this is the same case with the angles. if you were to have one congruent side inbetween two congruent angles, you would use ASA, which stands for angle side angle, to prove that the triangles are congruent. some more examples are:
side, side, angle =SSA.
angle, angle side = AAS. (the problem in question)
hope this helps :)
The answer is option C)
What is the AAS congruence rule?If two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of a second triangle, then the two triangles are congruent. This is the AAS congruence rule.
Given here in ΔVTY and ΔWYX
VY = WX , ∠VYT = ∠WXY and ∠VTY = ∠WYX
Therefore, by AAS congruence rule , we get ΔVTY≅ ΔWYX
Accordingly, by the property of congruence of triangles we get
TV = YW
Hence, option C) ΔVTY≅ ΔWYX by AAS, so TV = YW by def of ≅

What transformation of the parent function f(x) is made to get _ f(3x)? A a vertical stretch by 3 B.a vertical stretch by 1/3 C.a horizontal shrink by 3 D. a horizontal shrink by 1/3
Answers
The transformation of the parent function f(x) that is made to get f(3x) is a horizontal shrink by 1/3.The answer should be D.
The transformation of the parent function f(x) that is made to get f(3x) is a horizontal shrink by 1/3. Main answer:The given parent function is f(x).
The new function that we have to find is f(3x).
We know that the general form of a horizontal shrink is given by:f(x/a), where a is the horizontal shrink factor. We substitute 3 for a because 3 is the shrink factor that gets us from x to 3x.
Therefore,f(x/3) = f(3x)Thus, the transformation of the parent function f(x) that is made to get f(3x) is a horizontal shrink by 1/3.The answer should be D.
e can make use of the horizontal and vertical transformations to describe a transformation of the graph of a function. The horizontal transformation can be represented by the expression f(x - a) or f(x + a), while the vertical transformation can be represented by the expression f(x) + b or f(x) - b.

At top cruising speed, a mako shark can swim 4 kilometers in 1/10 hour. A blue whale can swim 5 kilometers in 1/4 an hour which animal swims faster at a top cruising speed? How much faster? Show your work.
Answers
Answer: Mako shark
Step-by-step explanation:
We will calculate the speed of the sharks to know which is faster.
A mako shark can swim 4 kilometers in 1/10 hour.
Speed = Distance/Time
= 4/(1/10)
= 40km/hour
A blue whale can swim 5 kilometers in 1/4 an hour.
This shows that the Mako shark is faster as it swims at rate of 40km/hour and the blue whale swims at 5km/hour. It's faster by 35km.
= 40km - 5km
= 35km

please help!! If the wind is blowing at 20 miles per hour, you can find the wind-chill temperature W (in degrees Fahrenheit) by using the equation W = 1.42T - 38.5, where T is the actual temperature (in degrees Fahrenheit). Solve this equation for T and write a reason for each step. What is the actual temperature if the wind chill temperature is -24.3°F and the wind is blowing at 20 miles per hour? thank you
Answers
first, move -38.5 to the other side of the equal sign. because you’re moving to a different side, you must change the negative sign to a positive.
14.2 = 1.42T
now, you have to divide both numbers by 1.42 to isolate T.
10 = T
The actual temperature is 10°F.
If the wind chill temperature is -24.3°F, actual temperature of the wind will be 10°F.
Equation for the chill temperature has been given as,
W = 1.42T - 38.5Here, W = Chill temperature
T = Actual temperature
Solve this equation for the value of T,
W = 1.42T - 38.5
W + 38.5 = 1.42T - 38.5 + 38.5 (Add 38.5 on each side)
W + 38.5 = 1.42T
[tex]T=\frac{W+38.5}{1.42}[/tex] (Divide each side by 1.42)
For W = -24.3°F
[tex]T=\frac{-24.3+38.5}{1.42}[/tex] (Substitute the value of W in the equation)
T = 10° F
Therefore, actual temperature will be 10°F if the wind chill temperature is -24.3°F.

x² − 8 − (9x + 2) = 9x + 2 − (9x + 2) (Subtract 9x+2 from both sides)

Marsha’s scores on seven tests were: 82, 78, 77, 93, 85, 91, and 86. What does she need to score on her next test to have an 86 average?
Answers
Answer:
The score of her next test is 96
Step-by-step explanation:
If there is a set of data with x terms, then the average is the sum of their values divided by x
Average = sum of values of the x terms ÷ x
We will use this rule to solve the question
∵ Marsha's scores on 7 test were 82, 78, 77, 93, 85, 91, 86
→ Find her total scores on the seven tests
∴ Her total scores = 82 + 78 + 77 + 93 + 85 + 91 + 86 = 592
∴ Her total scores on the 7 tests is 592
∵ Her average score on the 8 test is 86
→ Use the rule of the average to find her total score in the 8 test
∵ 86 = total scores ÷ 8
→ Multiply both sides by 8
∴ 86 × 8 = total scores × 8 ÷ 8
∴ 688 = total scores
∴ Her total scores on the 8 tests is 688
∵ Her total scores on the 7 test = 592
∵ Her total scores on the 8 test = 688
→ The difference between both totals is the score of her next test
∴ The score of her next test = 688 - 592 = 96
∴ The score of her next test is 96

Answer:
The angles are congruent, not supplementary. x = 20The angles are complementary, not supplementary. x = 17Step-by-step explanation:
1. The equation should be 5x = 100, because the marked angles are congruent.
Then, dividing by 5 gives ...
x = 100/5
x = 20
__
2. The angles have a sum of 90°, not 180°. The correct equation is ...
3x +39 = 90
x + 13 = 30 . . . . divide by 3*
x = 17 . . . . . . . . subtract 13
_____
* Sometimes when the terms of the equation have the coefficient of x as a common factor, I like to divide by that first. It makes all of the numbers smaller, so more comfortable for me to deal with. The usual method would be to subtract 39 before doing the division. You get the same answer either way.
Item 11 1/1 1/1 Math (Numeric): Erin has a total of 18 coins worth $2.05. All of the coins are either nickels, dimes, or quarters.

Answers
In the first item, Erin has a total of 18 coins with a combined value of $2.05. The coins consist of nickels, dimes, and quarters. It is stated that the number of nickels is twice the number of quarters, and we are asked to determine the quantities of each coin.
Let's assign variables to represent the number of each coin. Let N be the number of nickels, D be the number of dimes, and Q be the number of quarters. We have three equations based on the given information:
N + D + Q = 18 (the total number of coins is 18)
5N + 10D + 25Q = 205 (the total value of the coins is $2.05)
N = 2Q (the number of nickels is twice the number of quarters)
To solve this system of equations, we can substitute N = 2Q into the first two equations. Substituting N with 2Q in equation 1 gives us:
2Q + D + Q = 18
3Q + D = 18
Substituting N with 2Q in equation 2 gives us:
5(2Q) + 10D + 25Q = 205
10Q + 10D + 25Q = 205
35Q + 10D = 205
Now we have a system of two equations with two variables. By solving these equations simultaneously, we can determine the values of Q, D, and N.
