In the Exercises below, find the scale factor. Then list all pairs of congruent angles and write the ratios of the corresponding side lengths in a statement of proportionality.
Answer:
8) scale factor: 3
angles Q & L, S & N, r & M
sides 10 x 3 = 30, 6 x 3 = 18, 13 x 3 = 39
9) scale factor: 0.4
angles B & F, C & G, D & H, A & E
sides 9 x 0.4 = 3.6, 7.5 x 0.4 = 3, 10 x 0.4 = 4, 12 x 0.4 = 4.8
The scale factor for part (8) is 3, angles Q & L, S & N, R & M, for part (9) is 0.4 and angles of pair are congruent B & F, C & G, D & H, A & E
What is a scale factor?The ratio among comparable dimensions of an object and a model with that object, known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.
8)
Scale factor for the triangle LMN:
Let's suppose the scale factor is x
3x= 30 ⇒ x = 3
6x= 18 ⇒ x = 3
13x=39 ⇒ x = 3
So the scale factor is 3
Angles Q & L, S & N, R & M
39/13 = 30/10 = 18/6 = 3
9)
Scale factor for the triangle LMN:
Let's suppose the scale factor is y
12y= 4.8 ⇒ x = 0.4
9x= 3.6 ⇒ x = 0.4
10x=4 ⇒ x = 0.4
So the scale factor is 0.4
Angles B & F, C & G, D & H, A & E
4.8/12 = 3.6/9 = 4/10 = 0.4
Thus, the scale factor for part (8) is 3, angles Q & L, S & N, R & M, for part (9) is 0.4 and angles of pair are congruent B & F, C & G, D & H, A & E

Find the slope and the y-intercept of the line
y=-1/5*+9
Answer:
slope is -1/5 and 9 is the y intercept
Step-by-step explanation:
Suppose the function h(x) = 2x - 9 is translated up 5 units to become a new function,
i(x)
What's the equation of the new function?
A) i(x) = 2x - 4
B) i(x) = 77-9
C) i(x)= 2x- 14
D) i(x)= 7x- 4
Answer:
B
Step-by-step explanation:
Given that the function h(x) = 2x-9 is translated up 5 united to become a new function, i(x)
To find: Equation of new function
The graph of a function can be moved up, down, left, or right by adding to or subtracting from the output or the input.
Adding to the output of a function moves the graph up
Therefore,
Given function is:
h(x) = 2x - 9
Translated up by 5 units
Therefore, new function is:
i(x) = h(x) + 5
i(x) = 2x - 9 + 5
i(x) = 2x - 4
Thus Option B is correct

Answer:6 1/4
Step-by-step explanation:
Consider the function m(t) =-28/5t.
Angie states that the additive inverse is p(t) = 28/5t and the multiplicative inverse is r(t) = -28/5t . Is one (or both) of Angie’s conclusions correct?
Angie is correct about both inverses.
Angie is correct about neither inverse.
Angie is correct about the additive inverse only.
Angie is correct about the multiplicative inverse only.
Find the x and y intercepts of the lines 6x+y=4
Answer:
x int = (2/3,0)
y int = (0,4)
Step-by-step explanation:
x intercept y=0
6x+0=4
6x=4
x=4/6
x=2/3
(2/3,0)
y intercept x=0
6(0)+y=4
y=4
(0,4)
Answer:
(0,4) and ([tex]\frac{2}{3}[/tex], 0)
Step-by-step explanation:
6(0) + y = 4
y = 4
(0,4)
6x + 0 = 4
6x = 4
x = [tex]\frac{2}{3}[/tex]
([tex]\frac{2}{3}[/tex], 0)

Find the solution to the following system. Explain how you got your
answer, step-by-step.
3x + 4y = 36
y=-1/2x+8
Answer:
(x,y)=(4,6)
Step-by-step explanation:
3x+4y=36
y=-1/2 x+8
step 1: substitute the value of y
[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]
step 2: solve equation for x
[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]
3x-2x+32=36
x+32=36
x=36-32
x=4
step 3: substitute the value of x
[tex]y=-\frac{1}{2} (4)+8[/tex]
Step 4: solve equation for y
[tex]y=-\frac{1}{2} (4)+8[/tex]
y=-2+8
y=6
there for the answer is
(x,y)=(4,6)

The equation y=4.2x could represent a variety of situations. Write your own description of a situation represented by this equation. Decide what quantities x and y represent in your situation.
Answer:
The solution is given below:
Step-by-step explanation:
Given that
The equation is 4.2x
It could present the total price for the no of goods
Here we take an example
The price per chips is $4.2
And, the number of chips purchased be x
And, the total price would be y
So if 5 chips were purchased, so the total price would be
y = $4.2 (5)
= $21
hence, the above represent the description

Vhen flipping a coin, what is the probability of landings
meads and then heads again?
0.25% chance or 1/4th.
You have a 50/50 chance of getting heads or tails on a throw. .50 for each.
If you do get heads, there's the same chance of getting another heads.
Multiply the .50% chance of getting heads by .50 again, and you end up with a 0.25% chance total of getting heads twice in a row.
