Solve the following equation for y. Hint: Get y alone on one side of the equation.
4x + 2y = 4
A.
y = -2x + 2
B.
y = -4x - 4
C.
y = 2x + 2
D.
y = x - 1
Answer:
y = 2 - 2x
Step-by-step explanation:
Answer:
A. y = -2x + 2
Step-by-step explanation:
4x + 2y = 4
Move 4x to the other side of the equation.
2y = 4 - 4x
Divide the whole thing by 2 to get y by itself.
y = 2 - 2x
which can also be written as
y = -2x + 2
Hope this helps! :)

2(x + 7)2/3 = 8
A. -15 and 1
B. -15
C. 1
D. no solution
Answer:
-1 option D (no solution)
Step-by-step explanation:
2(x + 7)2/3 = 8
2(X+7)2/3=8
4(X+7)=24
4x+28=24
4x=24-28
4x=-4
X=-4/4
X=-1
So the answer is -1

How do you determine the x and y-intercepts from an equation or graph?
What is the domain of the function represented by the graph?
Answer: Choice C. [tex]x \ge -3[/tex]
============================================
Explanation:
The domain is the set of all allowed x inputs.
Here we see that x = -3 is the smallest x value possible as it is from the left-most point. The graph goes on forever to the right, so there is no largest x value. Effectively infinity is the largest x value even though infinity is not a number.
We can say the domain is [tex]-3 \le x < \infty[/tex] which can be simplified to [tex]-3 \le x[/tex] or [tex]x \ge -3[/tex]
In short: x can be -3 or larger.

Last year, the hiking club had 25 members. This year, there’s 37. What is the percent increase?
Answer:
The hiking club's member count increased by 48%.
Step-by-step explanation:
We are given two data values: 25 members and 37 members. We need to determine how many members the club gained first. We can set up an equation where we solve for an unknown, or x, in this case.
[tex]25 + x = 37\\\\x = 12[/tex]
The club increased by 12 members, so now we can divide this value by the initial amount of members and multiply the decimal we receive by 100 to express it in percentage form.
[tex]\frac{12}{25} =0.48\\\\0.48 \times 100 = 48\%[/tex]
Therefore, the club's member count increased by 48%.
Answer:
25+12=37
There would be 48%.

In triangle ABC, we can draw a perpendicular line segment from vertex C to segment AB. The intersection of AB and the perpendicular is called E. We know that BE is the shortest distance from B to and that is the shortest distance from A to CE because of the shortest distance theorem. Therefore, BC > BE and AC > AE. Next, add the inequalities: BC + AC > BE + AE. Then, BE + AE = BA because of the . Therefore, BC + AC > BA by substitution.

A hailstorm caused damage at a car lot. A compact car usually sells for
$27,500, but the damaged cars are discounted to $17,875. What was the
percent discount on a damaged compact car?
Answer:
$655.61 is the new price. it was decreased in price by 65%
Step-by-step explanation:
A percentage is a number or ratio that can be expressed as a fraction of 100.
The percent discount on a damaged compact car is 35%.
What is a percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
We have fractions for different percentages.
50% = 1/2
20% = 1/5
25% = 1/4
10% = 1/10
We have,
The selling price of the compact car = $27,500
The discounted price of the damaged compact car = $17,875
The discounted percentage of the car:
= (27,500 - 17,875) / 27,500 x 100
= 9625 / 27500 x 100
= 35%
Thus the percent discount on a damaged compact car is 35%.

find the nth term of this quadratic sequence 4, 9, 16, 25, 36
Answer:
well the sequence is the perfect squares
Step-by-step explanation:
Answer:
[tex]a_{n}[/tex] = (n + 1)²
Step-by-step explanation:
The sequence of square numbers is
n | 1 2 3 4 5 6
n² | 1 4 9 16 25 36
Given
4 , 9, 16, 25, 36 ← moved 1 place to the right
Thus
4 = (1 + 1)² , 9 = (2 + 1)² , 16 = (3 + 1)² , etc
In general the n th term is
[tex]a_{n}[/tex] = (n + 1)²
PLEASE SHOW THE WORK HELP ME OUT
Answer:
see explanation
Step-by-step explanation:
The 2 angles are adjacent and supplementary, thus
2x + x + 84 = 180 , that is
3x + 84 = 180 ← required equation
Subtract 84 from both sides
3x = 96 ( divide both sides by 3 )
x = 32
Thus
∠ 1 = 2x = 2(32) = 64°
∠ 2 = x + 84 = 32 + 84 = 116°

Maricella solves for x in the equation 4 x minus 2 (3 x minus 4) + 4 = negative x + 3 (x + 1) + 1. She begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation. Which best explains why Maricella’s strategy is incorrect?
Answer:
It is wrong because she should simplify both sides of the equation,distribute, combine like terms,subtract and divide to get the final answer.
4x−2(3x−4)+4=−x+3(x+1)+1
Step 1: Simplify both sides of the equation.
4x−2(3x−4)+4=−x+3(x+1)+1
4x+(−2)(3x)+(−2)(−4)+4=−x+(3)(x)+(3)(1)+1(Distribute)
4x+−6x+8+4=−x+3x+3+1
(4x+−6x)+(8+4)=(−x+3x)+(3+1)(Combine Like Terms)
−2x+12=2x+4
−2x+12=2x+4
Step 2: Subtract 2x from both sides.
−2x+12−2x=2x+4−2x
−4x+12=4
Step 3: Subtract 12 from both sides.
−4x+12−12=4−12
−4x=−8
Step 4: Divide both sides by -4.
−4x−4=−8−4
