triangle abc is similar to triangle aed
Answers
Answer:
9/5 or 1.8
Step-by-step explanation:
triangle aed is larger than triangle abc by a scale factor of 5; we know this because side ed is 5 units and cb, the corresponding side in triangle abc, is 1. if ad has a length of 9, the length of ab must be 9 divided by five. thus, z is equal to 9/5 or 1.8.
Write an equation for a line perpendicular to f(x)=5x−1 and passing through the point (5,20)
Answers
Answer:
y - 20 = (-1/5)(x - 5)
Step-by-step explanation:
The slope of the given line is 5. The slope of any line perpendicular to the given line is the negative reciprocal of the given slope:
Slope of perpendicular line here is -1/5.
We use the point-slope formula as a framework here:
y - 20 = (-1/5)(x - 5)

Answers
A sequence defined by the rule f(n)=4f(n-1)+2.if f(1)=3 then find f(4)=?
Answers
Answer:
f(4) = 6
Step-by-step explanation:
Given the rule f(n) = 4f (n - 1) + 2 where f(1) = 3, f(n) is just a fancy way to name the variable y. As you've seen before, there are equations that are usually y equals x and something. For example:
y = mx + b
is the same thing as
f(n) = y = mn + b.
It might be that you have multiple of the same equation where f(n) and f(x) have two different outcomes.
The f(n) part (bolded) is the "x variable" in this equation. So in f(1), n = 1.
f(n) = 4f (n - 1) + 2
f(n) = (4fn - 4f) + 2
f(n) = (n) + 2
f(1) = 1 +2
3 = 3
Now do the same thing for f(4):
f(n) = 4f (n - 1) + 2
f(n) = (4fn - 4f) + 2
f(n) = (n) + 2
f(4) = 4 + 2
f(4) = 6

Christina had a total of $120 to spend while shopping. She already spent $68 on clothes . She wants to buy some video games that are on sale for $10 each, including tax.
Answers
Answer:
5 video games.
Step-by-step explanation:
In order to find the total number of video games that Tracy can buy with the money, she has we first need to find how much money she has left after buying the clothes. To do this we subtract the amount she spent on clothes by the initial total that Christina had.
120 - 68 = 52
Now that we know Christina has a remaining $52, we can divide this amount by the value of each individual game ($10) in order to calculate how many she can actually afford.
52 / 10 = 5.2
Finally, we can see that she can afford to only buy 5 video games.

what is the value of 6(2b-4) when b+5?
Answers
Answer:
The value of 6(2b-4) is 36.
Step-by-step explanation:
Given expression: 6(2b-4)
To find the value of 6(2b-4) at b=5, we need to substitute the b=5 in the expression, we get
6(2(5)-4)
= 6(10-4)
=6(6)
= 6x6=36
⇒ 6(2(5)-4)=36
Answer:
The value of 6(2b-4) when b=5 is 36.
Step-by-step explanation:
Given expression: 6(2b-4). To find the value of 6(2b-4) at b= 5, we need to substitute the b=5 in the expression, we get….Therefore, the value of 6(2b-4) is 36, when b=5.

4. Find
A) 64.5
B) 68.5
C) 72.5
D) 76.5
Answers
Answer:
A) 64.5
Step-by-step explanation:
A circle's measurement is 360°.
It is given that arcPQ is 113° and arcQM is 118°. Subtract 113 and 118 from 360:
360 - (113 + 118) = 129°
ArcPM is 129 degrees. Note that this is a inscribed, but not a central angle. m∠PQM = (ArcPM)/2
m∠PQM = (129)/2
m∠PQM = 64.5
A) 64.5 is your answer.
