What is the solutions of the following system of equations.
y = -2x + 2
y = x - 1
Answer:
x=1
y=0
Step-by-step explanation:
(x-1)=-2x+2
3x-1=2
3x=3
x=1
-2(1)+2
-2+2=0
Answer:
x =1 y=0
-2x +2= x-1 (subtract 2 from both sides)
-2x= x-3 (subtract x from both sides)
-3x= -3 (divide each side by -3)
x=1
plug it in
y= (1) -1
y=0

Hey y’all. I’m so embarrassed and I want to hit my head so BAD:( I’m literally crying. So I had a test in math and I’ve always been cheating and I was the best math student but when the class was gonna end I told the teacher I only have two questions and she told me to still stay and when I finished the submit button didn’t work and the teacher told me to present my screen and I did but when I did the teacher face wasn’t happy because when I showed her my screen in the tabs I had tabs that help me cheat the test. But the teacher didn’t tell me anything and she told me that if I have the notes for all my questions answers and I didn’t know what to say so I said yes! But I told her if I should take pictures of the answers and she said no. And I started panicking so she told me to reload the WHOLE THING so I did and all my 18 questions answers deleted and I told the teacher I had to go to my other class and she said bye. I’m literally crying. I’m hitting my head so hard. Karma is real:( F

You stand 50 feet from a monument. The angle of depression from the top of the monument to your feet is 64 degrees. Approximately how tall is the monument
Answer:
The monument is approximately 86.6 feet tall
Step-by-step explanation:
The given monument parameters are;
The distance of the person from the monument = 50 feet
The angle of depression from the top of the monument to the person's feet = 64°
Given that the angle of elevation to the top of the monument from the person's feet = The angle of depression from the top of the monument to the person's feet, we have;
tan(Angle of depression) = tan(Angle of elevation) = (The height of the monument)/(The distance from the monument)
∴ The height of the monument = tan(Angle of depression) × The distance from the monument
Substituting the known values, gives;
The height of the monument = tan(60°) × 50 ≈ 86.6
The height of the monument ≈ 86.6 feet.

Answer:
Heredity refers to the genetic heritage passed down by our biological parents. It’s why we look like them! More specifically, it is the transmission of traits from one generation to the next. These traits can be physical, such as eye color, blood type or a disease, or behavioral. For example, the hygienic behavior of honeybees that drives them to remove sick larvae from the nest is inherited behavior.

Answer:
61
Step-by-step explanation:
a triangles angles equal 180 so 180-10-19-90 = 61
Answer:
-9
Step-by-step explanation:
Since the opposite angles of both sides are congruent we know that the sides must be congruent also. Therefore, to solve for x we can set them equal to each other.
So the equation will be x+19=10, to solve we must isolate the variable.
First, subtract 19 from both sides
x+19-19=10-19
Then, simplify
x=-9

Answer:
y = 1/8x + 25/8
Step-by-step explanation:
Which equation below and solution for x does the model represent?
A) 2x + 2x = 85, x=42.50
B) 4 + x = 85, x=21.00
C) x + x + x = 85, x=21.00
D) 4x = 85, x=21.25
Answer:
Option D
Step-by-step explanation:
Cost of 4 shirts all together = $85
Model given in the picture attached will be,
x + x + x + x = 85
4x = 85
[tex]\frac{4x}{4}=\frac{85}{4}[/tex]
x = 21.25
Therefore, Option D will be the correct option.

The price of a video game was reduced from $60 to $45. By what percentage was the price of the video game reduced?
ok now help me please!!
Answer:
x = 9
Step-by-step explanation:
The linear pair have a sum of 180°, thus
3x + 15x + 18 = 180
18x + 18 = 180 ( subtract 18 from both sides )
18x = 162 ( divide both sides by 18 )
x = 9

Mia and Evette played a game in which they scored 10 points for each correct answer and lost 20 points for an incorrect answer. Mia answered 7 questions correctly and 3 questions incorrectly. What was Mia's overall score? *
We are told that:
Correct points = 10 per answer
Incorrect points = 20 per answer
Mia answered 7 questions correctly and 3 questions incorrectly.
Hence:
7 (10) + 3(20)
= 70 points - 60 points
= 10 points
Mia's score is 10

In 25 minutes Jezebel can run 10 laps around the track. Part I) Determine the unit rate for the number of laps she can run per minute. Part II) Find the constant of proportionality for this situation.
Answer: See explanation
Step-by-step explanation:
a. Determine the unit rate for the number of laps she can run per minute.
This will be calculated as the number of minutes used divided by the number of laps which will be:
= 25 / 10
= 2.5 minutes per lap.
b. Find the constant of proportionality for this situation.
We will use the formula y = kx
where y = 25, x = 10, k = constant of proportionality.
Therefore, y = kx
25 = 10k
k = 25/10
k = 2.5
The constant of proportionality is 2.5
