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! :)
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)
and that's your final answer! hope this helped :)

[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...

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

Joshua tells his friends that for there to be snow it has to be 32o F. He uses his thermometer outside and sees snow. He finds it is only is 34oF. What is his percent error? (Round to the nearest tenth)
Answer: Percentage error = -5.9%
Step-by-step explanation:
Step 1
Percentage error =Approximate Value − theoretical Value / Theoretical value × 100%
or
Percentage error = Assumed number - Result number / Result number x 100
Given Assumed number / Approximate Value= 32o F
Result number/ Theoretical value= 34o F.
Step 2---
Percentage error = (32 - 34)/ 34 x 100
= - 2/34 x 100
= - 5.88%
Joshua was in error by - 5.88 % which when rounded to nearest tenth gives - 5.9%.
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.

Hence, 47 % of the marching band is students.
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.
