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

[tex]y = - 3x + 4[/tex]
Add sides 3x
[tex]y + 3x = 3x - 3x + 4[/tex]
[tex]3x + y = 4[/tex]
_________________________________
[tex]1) \: 3x + y = 4[/tex]
[tex]2) \: - 4x + y = - 10[/tex]
Multiply sides of the (( equation 2 )) by - 1
[tex]1) \: 3x + y = 4[/tex]
[tex]2) \: 4x - y = 10[/tex]
Add up equations
[tex]3x + 4x + y - y = 4 + 10[/tex]
[tex]7x = 14[/tex]
Divide sides by 7
[tex] \frac{7x}{7} = \frac{14}{7} \\ [/tex]
[tex]x = 2[/tex]
Put the value of x in one of the (1) or (2) equations to find the value of y .
I put it in equation 1 :
[tex]3x + y = 4[/tex]
[tex]3(2) + y = 4[/tex]
[tex]6 + y = 4[/tex]
[tex]y + 6 = 4[/tex]
Subtract sides 6
[tex]y + 6 - 6 = 4 - 6[/tex]
[tex]y = - 2[/tex]
And we're done...

What is the percent of change from 5 to 9?
Hey there! It would be 44% decrease...
Explanation:
So we know that 9 would be 100%. So what is the percent of change?
So let divide 5 with 9. 5 divide 9 would be 0.56.
Great, now we can subtract 100 with 0.56 since we know that 56% is 5. 100-56 is 44. This means that the percent decrease would be 44%.
Final Result: 44%
The percent change from 5 to 9 is 80%.
What is percentage?Percentage is a measurement to find the value of a given number out of hundred.
Given that,
The original number is 5.
The number changes to 9 .
Increase in number = 9-5 = 4
The percentage change = 4/5×100 = 400/5 = 80%
The percentage change is 80% from 5 to 9.

There are 80 tickets in a bag and the ratio of winning tickets to losing tickets is 2 : 8. How many of each kind of ticket are in the bag?
Given:
Total number of tickets = 80
Ratio of winning tickets to losing tickets is 2 : 8.
To find:
The number of tickets of each kind in the bag.
Solution:
Let the number of winning and losing tickets are 2x and 8x respectively.
Total number of tickets = 80
[tex]2x+8x=80[/tex]
[tex]10x=80[/tex]
Divide both sides by 10.
[tex]x=\dfrac{80}{10}[/tex]
[tex]x=8[/tex]
Now,
Winning tickets : [tex]2(8)=16[/tex]
Losing tickets : [tex]8(8)=64[/tex]
Therefore, the winning and losing tickets are 16 and 64 respectively.

At Pizza pizzazz the cost of a square pizza depends on the total square inches. A small
Pizza is 5 inches on each side and cost four dollars plus $0.05 per square inch. A medium pizza is 8 inches on each side and cost $3.50 plus $0.04 per square inch. What is the difference in price between a small pizza and a medium pizza?
Answer:
The difference in price between a small pizza and a medium pizza is $0.81
Step-by-step explanation:
Small pizza
Side = 5inch
Area = 25 sq.in
Cost = $4 +0.04*25
= 4 + 1.25 = $5.25
Medium pizza
Side = 8inche
Area = 64 sq.in
Cost = 3.50 + 0.04*64 = $6.06
Difference = Medium pizza - small pizza
= 6.06 - 5.25
= $0.81

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.
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.

3. Write an equation in point-slope form that describes the line with a slope of 2 that contains the point (4,-3)?
Answer:
y + 3 = 2 (x - 4)
Step-by-step explanation:
y - y₁ = m (x - x₁)
substitute (4, -3) in for (x₁, y₁)
y - (-3) = m (x - 4)
substitute the slope (2) in for m (m=slope) and simplify (y - (-3)) to (y +3) because subtracting a negative is the same as adding a positive
y + 3 = 2 (x - 4)
