y = 2x + 4
y = 3x + 6
Solve for x
Answer:
(-2,0)
Step-by-step explanation:
The system of equations is graphed on the coordinate plane.
y=-5/3x+3
y=1/3x - 3
Enter the coordinates of the solution to the system of equations
in the boxes.
Answer: The solution is (3, -2)
This means that x = 3 and y = -2 pair up together.
=====================================================
Explanation:
The solution is where the two lines cross. Note if we started at the origin (0,0) and moved to the right 3 units, and then down 2 units, we would arrive at the location (3, -2).
-----------------
As a way to check, we can plug x = 3 into each equation. We should get y = -2 as a result for each equation
y = (-5/3)x + 3
y = (-5/3)*3 + 3
y = -5+3
y = -2
The first equation is confirmed. Let's check the second equation
y = (1/3)x - 3
y = (1/3)*3 - 3
y = 1 - 3
y = -2
Both equations have the y value equal -2 when x = 3. Therefore, the overall solution is confirmed.
If p + q has a value that is exactly 1/3 less than p, what is the value of q
Answer:
- ⅓
Step-by-step explanation:
p + q = p - ⅓
q = (p - p) - ⅓
q = - ⅓

Consider the diagram and angle measures shown below What is the value of m angle 3 ?
Answer:
The answer is below
Step-by-step explanation:
m∠lon = m∠2 (vertical opposite angles are equal)
m∠lon = m∠1 (corresponding angles are equal).
Therefore; m∠2 = m∠1 (substitution property)
3x + 25 = 7x + 5
Subtracting 5 and 3x from both sides of the equation:
3x + 25 - 5 - 3x = 7x + 5 - 5 - 3x
4x = 20
dividing through by 4:
4x / 4 = 20 / 4
x = 5
Given that:
m∠3 = -2x + 70
substituting x = 5:
m∠3 = -2(5) + 70 = 60
m∠3 = 60°
Therefore:
m∠4 + m∠2 + m∠3 = 180° (substitution)
(155 - 3x) + (7x + 5) + (-2x + 70) = 180
(-3x + 7x - 2x) + (155 + 5 + 70) = 180
2x + 230 = 180
2x = -50
x = -25
Therefore; m∠3 = -2x + 70 = -2(-25) + 70 = 50 + 70
m∠3 = 120°
Which two ratios represent quantities that are proportional?
Answer:
D. 45/18 = 35/14Step-by-step explanation:
Lets simplify the ratios where possible and compare:
A. 3/4 = 9/12 ≠ 5/12B. 32/20 = 16/10 ≠ 22/10C. 7/5 = 14/10 ≠ 14/9D. 45/18 = 5/2 (divide by 9) and 35/14 = 5/2 (divide by 7)The last two ratios represent proportional quantities

Answer:{ x,y } = { - 2, - 3 }
Step-by-step explanation: 4x = 2y - 2
x = y/2 - 1/2
3. (y /2 - 1/2 ) + 2y = - 12
7y/2 = - 21/2
7y = - 21
x = y/2 - 1/2
y = - 3
x = (/2) ( - 3 ) - 1/2 = - 2

Give your answer in its simplest form
Answer:
[tex] \frac{1}{2} [/tex]
Step-by-step explanation:
[tex] \frac{130}{260} = \frac{1}{2} [/tex]
The fraction of the boys of Year 11 is 1/2.
What is a fraction?Fractions are used to represent smaller pieces (or parts) of a whole.
Given that, there are total 260 students of 11 years in which 130 are girls and 130 are boys.
The fraction of boys of 11 years = 130/260 = 1/2
Therefore, half of the strength of students are boys.
Hence, The fraction of the boys of Year 11 is 1/2.

In AABC, if m ZA = 25° and mZB = 108°, what is mZC?
Answer:
Step-by-step explanation:
Sum of all the angles of a triangle = 180°
∠A + ∠B + ∠C = 180
25 + 108 + ∠C = 180
133 + ∠C = 180
∠C = 180 - 133
∠C = 47°
In basketball, each shot made is worth 1, 2, or 3 points. Miles scored a total of 27 points in his most recent game. He made three 1-point shots
and four 3-point shots.
How many 2-point shots did he make?
Answer:6
Step-by-step explanation:
Subtract the three 1 point shots
Subtract the four 3 point shots
You are left with 12, and you split that in 2 because they're 2 point shots.

While shopping, Dawn finds a backpack that she likes on the sale rack. Its original price is $60,
but everything on the rack comes with a 30% discount. Dawn also has a coupon for 15% off of
her total purchase.
Dawn says, "Thirty percent and fifteen percent make forty-five percent and 45% of $60 is $33,
so it will cost $33."
Is Dawn correct? Explain why or why not. Be sure to support your reasoning with a
mathematical model.
No. Because 33 $ is the money deducted from the 60 $. Dawn bought everything for less than 60 $.
So, if Dawn purchases everything on the rack with a 30% discount and 15% coupon the total will indeed make 45%.
We have to take 100% - 45%= 55% to know the reduction number. Let's proceed to the calculations now.
100%= 60 $
1%=60/100
55%= 60/100 × 55 = 33 $
Now NOTE; 33 $ is the money reduced from the 60 $. So, logically, 33 $ isn't the amount which Dawn purchased the whole rack.
To find the amount at which she purchased everything, we need to do,
60 $ - 33 $ = 27 $
