Devon just became a personal trainer and is finalizing her pricing plans. One plan is to charg
$51 for the initial consultation and then $48 per session. Another plan is to charge $38 for
the consultation and $49 per session. Devon realizes that the two plans have the same cost
for a certain number of sessions. What is that cost? How many sessions is that?
The cost on either plan is $|
for
sessions.
Submit
Answer:
13 sessions
The cost for either plan: $675
Step-by-step explanation:
48x + 51 = 49x + 38

Multiple Choice Find the mean: 12, 8, 7, 10, 8, 8, 10
Answer:
The mean is 9
Step-by-step explanation:
To find the mean, all you do is add up all the numbers and then divide by how many numbers there are. In this case, adding all then numbers up gives you 63, and there are a total of 7 numbers. 63 divided by 7 =9

A square has a diagonal that is 36 mm long. What is the area of the square?
If necessary, round your answer to the nearest whole number.
Answer:
18mm
Step-by-step explanation:
in the triangle we will say:
36=x^2 +x^2
36=2x^2
so x will be = root 18
as the area = x*x
so root 18 * root18=18mm^2
Triangle ABC is reflected across the line y=2x to map onto triangle RST. Select all statements that are true.
AB = RS
AB = 2RS
ABC ~ RST
ABC = RST
m<BAC = m<SRT
m<BAC = 2m<SRT
The reflection transformation in the question is a rigid transformation,
therefore, the image and the preimage are congruent.
The statements that are true are;
AB = RS∠ABC ~ ∠RSTΔABC = ΔRSTm∠BAC = m∠SRTReasons:
The given parameter are;
Triangle ΔABC is reflected across the line 2·X, to map onto triangle ΔRST
Required:
To select the true statements
Solution:
A reflection is a rigid transformation, therefore, the distance between corresponding points on the image and the preimage are equal.
Therefore;
AB = RS
BC = ST
AC = RT
Given that the image formed by a reflection is congruent to the preimage, we have;
ΔABC ≅ ΔRST
∠ABC ≅ ∠RST
m∠ABC = m∠RST by the definition of congruency
∠BCA ≅ ∠STR
m∠BCA = m∠STR by the definition of congruency
∠BAC ≅ ∠SRT
m∠BAC = m∠SRT by the definition of congruency

A = (b1 + b2) h / 2
I'm so confused, and i need to solve for h.
Answer:
Step-by-step explanation:
Begin by multiplying both sides by 2
2*A = 2*(b1 + b2) * h/2 Cancel the 2s
2A = (b1 + b2 ) * h Divide both sides by (b1 + b2)
2A/(b1 + b2) = (b1 + b2)*h / (b1+b2) Cancel B1 + b2
2A/(b1 + b2) = h

Joseph compared the graphs of two functions. The first function wasf(x)=−2x+6. The second function fits the values in the table: x 2 5 8 11 y 2 -4 -10 -16 What is the distance between the y-intercepts of the two functions?
Answer: No difference
Step-by-step explanation:
The function f(x)=-2x+6 will produce the very same points in the table.
x y y calculated
2 2 2
5 -4 -4
8 -10 -10
11 -16 -16
The points are all on the line y=-2x+6. They describe the same line, which will have the same intercept.
(4,-3),m=-1 in standard form
Answer:
Step-by-step explanation:
m = -1 ; ( 4 , -3)
y - y1 = m(x - x1)
y - (-3) = -1(x - 4)
y+ 3 = -x + 4
Add x to both side.
x +y + 3 = 0
Subtract 4 from both sides
x + y + 3 - 4 = 0
x +y - 1 = 0

Answer:
26.6
Step-by-step explanation:
- 26.6 / - 1
- 26.6 = - 1 x 26.6
- 1 = - 1 x 1
- 26.6 / - 1
= ( - 1 x 26.6 ) / ( - 1 x 1 )

The next model of a sports car will cost 4.1%, more than the current model. The current model costs $58,000 How much will the price increase in dollars? What
will be the price of the next model?
Answer:
$60378
Step-by-step explanation:
$58,000 represents 100% of the original cost
100 + 4.1= 104.1% = 104.1/100 = 1.041
Multiplying by 1.041 gives the cost after the increase
price = 53000 x 1.041 = $60378
