what’s the scale factor ?
=======================================================
Explanation:
The vertical side of the blue triangle is PR = 2
The corresponding vertical side of the green triangle is P'R' = 4
The scale factor is the ratio of those two corresponding sides. So we divide the two side lengths.
scale factor = (P'R')/(PR) = (4)/(2) = 2
---------------------
We could also say:
scale factor = (R'Q')/(RQ) = (6)/(3) = 2
Or you could find the lengths of PQ and P'Q' through the distance formula, or Pythagorean theorem, and apply the same idea as shown above.
How many solutions does this system of equations have?
y = –2x + 2
2y + 4x = 4
Step-by-step explanation:
First we solve it.
I'll use substitution.
In the first equation y equals -2x+2 so we can apply that to the second equation
2y + 4x = 4
2(-2x+2) + 4x = 4
distribute
-4x+4+4x=4
simplify
4=4
To figure out how many solutions it has:
•If both side of the equal sign are exactly the same: Infinitely many
ex: 6x=6x
•If both sides of the equal sign do not match when completely simplified: No solutions
ex: 3x=-5x
•If it creates an equation: 1 solution
ex: x=3+2y
Since both sides of the equal sign are 4, we have infinitely many solutions.

Help!! ASAP!! Which ordered pair(s) are solutions to 3x − y = 1? Select all that apply.
A. (−2, −7)
B. (−1, −4)
C. (0, 1)
D. (3, 8)
Answer:
A, B, and D
Step-by-step explanation:
Substitute all the coordinates into the equation. (x, y)
3(-2) - (-7) = 1
-6 - (-7) = 1
1 = 1
3(-1) - (-4) =1
-3 - (-4) = 1
1 = 1
3(0) - (1) = 1
0 - (1) = 1
-1 does not equal 1
3(3) - (8) = 1
9 - (8) = 1
1 = 1
The ordered pairs which are solutions to the equation 3x − y = 1 are:
Choice A. (−2, −7)Choice B. (−1, −4)Choice D. (3, 8)By testing;
For A. (−2, −7); we have;
3(-2) − (-7) = 1-6 + 7 = 11 = 1 ..... SolutionFor B. (−1, -4); we have;
3(-1) − (-4) = 1-3 + 4 = 11 = 1 ..... SolutionFor C. (0, 1); we have;
3(0) − (1) = 10 - 1 = 1-1 = 1 ..... No SolutionFor D. (3, 8)
3(3) - (8) = 19 - 8 = 11 = 1..... SolutionRead more on equation solutions:

state the given statements is true or false. If areas of two rectangles are the same, then they are congruent
Hey there!
This answer to your question is it is false.
This is because you could have a rectangle with a length of 6 and a width of 4, and the area would be the same as a rectangle with a length of 8 and a width of 3. They would both be 24.
Hope it helps and have an amazing day! Stay safe!

which value for the constant c makes z =-5/4 an extraneous solution in the following equation?
[tex] \sqrt{4z + 9} = cz + 8[/tex]
Answer:
c=8
Step-by-step explanation:
The value of c that makes z = -5/4 an extraneous solution is c = 24/5.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The equation is given as:
√{4z + 9} = cz + 8
An extraneous solution is a solution that is not a valid solution to the original equation, but it is obtained during the process of solving the equation. In this case, the extraneous solution is z = -5/4.
To determine the value of c that makes z = -5/4 an extraneous solution, we can substitute -5/4 for z in the original equation. This gives us the following:
√{4 × -5/4 + 9} = -5/4 × c + 8
√{-5 + 9} = -5/4 × c + 8
√4 = -5/4 × c + 8
2 = -5/4 × c + 8
5/4 × c = 8 - 2
5/4 × c = 6
c = 6 × 4/5
c = 24/5
Therefore, the value of c that makes z = -5/4 an extraneous solution is c = 24/5.

It's that because there are 3/4 cups of honey for one cake. To use for 15 cakes, you would have to multiply it by 15.
For #3:
[tex]\frac{7}{8}[/tex] ÷ [tex]\frac{3}{4}[/tex].
It's that because the baker has 7/8 cups of honey. It takes 3/4 cups of honey for one cake. So you have to divide it by 3/4 cups in order to find out how many cakes.

Em de terminado dia, sofia voltava de sua casa 2h30min acima do horario que sua mãe determinou para sua própria segurança . Sabendo que o horário que sua mãe determinou foi as 20h, qual horário que ela estava voltando?
Responda:
22:30
Explicação passo a passo:
Dado que :
Hora definida pela mãe = 20h00
Número de horas além do tempo definido = 2 horas e 30 minutos
Hora em que ela voltou para casa:
(tempo definido pela mãe + número de horas além do tempo definido)
(20h + 2 horas e 30 minutos) = 22h30

Find the measure of the acute angle that line y=1/3x+4 makes with a horizontal line. Round your answer to the nearest tenth.
Also, I hope you are having a good day.
Answer:
The measure of the acute angle is 18.4°
Step-by-step explanation:
The angle between a line of equation y = m x + b and the positive part of the x-axis is Ф = [tex]tan^{-1}[/tex](m), which means tan Ф = m, where m is the slope of the line
Let us use this rule to solve the question
∵ A line of equation y = [tex]\frac{1}{3}[/tex] x + 4 makes with a horizontal line an acute ∠
→ Compare the equation of the line by the form of the equation above
∴ m = [tex]\frac{1}{3}[/tex]
→ Assume that the acute angle is Ф
∴ The acute angle between the line and the horizontal line is Ф
→ By using the rule above
∵ tan Ф = m
∴ tan Ф = [tex]\frac{1}{3}[/tex]
→ Use [tex]tan^{-1}[/tex] to find Ф
∵ Ф = [tex]tan^{-1}[/tex] ( [tex]\frac{1}{3}[/tex] )
∴ Ф = 18.43494882
→ Round it to the nearest tenth
∴ Ф = 18.4°
∴ The measure of the acute angle is 18.4°
