Rearrange y =1/2x+1to make x the subject.
❤❤❤❤❤❤❤❤❤❤❤❤❤❤
[tex]y = \frac{1}{2} x + 1 \\ [/tex]
Multiply sides by 2
[tex]2 \times y = 2 \times ( \frac{1}{2} x + 1) \\ [/tex]
[tex]2y =( 2 \times \frac{1}{2} x) + (2 \times 1) \\ [/tex]
[tex]2y = x + 2[/tex]
[tex]x + 2 = 2y[/tex]
Subtract sides 2
[tex]x + 2 - 2 = 2y - 2[/tex]

The answer is x = 2y - 2Step-by-step explanation:
Question: y = 1/2x + 1
Given:
equation: y = 1/2x + 1
Unknown:
Equation in x = ?
1. Move the x variable to the side that the y is on.
y = 1/2x + 1
-1/2x -1/2x
2. Move the y to the side of the y-intercept
y - 1/2x = 1
-y - y
3. Divide both sides by -1/2 or multiply by -2
-1/2x = -y + 1
*-2 -2(-y + 1)
The answer is x = 2y - 2

Answer:
What problem do you need help with.
Ingrid types 3 pages in the same amount of time that Tanya types 4.5 pages. Write a proportion that could be used to find the number of pages Tanya will have typed when Ingrid has typed 11 pages, if they start typing at the same time. Use x to represent the number of pages Tanya has typed.
Answer:
16.5 pages
Step-by-step explanation:
Number of pages Ingrid types = 3
Number of pages Tanya types = 4.5
The proportion to find how many pages Tanya would have typed (x), if Ingrid typed 11 pages would be as follows:
3 : 4.5 = 11 : x
Thus:
[tex] \frac{3}{4.5} = \frac{11}{x} [/tex]
Cross multiply
[tex] 3*x = 11*4.5 [/tex]
[tex] 3x = 49.5 [/tex]
Divide both sides by 3
x = 16.5 pages

Gary's jogging average speed is represented by the equation y=3.5x where y is the distance in miles and x is the time in hours. How far can he go in 84 minutes?
Answer:
Gary can go 4.9 miles in 84 minutes.
Step-by-step explanation:
First, you need to determine the amount of hours 84 minutes represent considering that 60 minutes are equal to an hour:
60 minutes → 1 hour
84 minutes → x
x=(84*1)/60=1.4 hours
Now, 1.4 hours would be the time which is x and you can replace the value on the formula to find y:
y=3.5x
y=3.5(1.4)
y=4.9
According to this, the answer is that Gary can go 4.9 miles in 84 minutes.
the equation is: y = -32 +2
Select all of the equations that would be perpendicular to this line.
y = -31 - 2
y = 2x - 5
y = {2 – 3
y = 12 +7
y = -32 +1
y=i<+3.63917
y = –2 – 3
y = -4.1 - 32
Answer:
y = [tex]\frac{1}{3}[/tex] x - 3 ⇒ 3rd answer
y = [tex]\frac{1}{3}[/tex] x + 7 ⇒ 4th answer
y = [tex]\frac{1}{3}[/tex] x + 3.63917 ⇒ 6th answer
y = [tex]\frac{1}{3}[/tex] x ⇒ 8th answer
Step-by-step explanation:
The product of the slopes of the perpendicular lines is -1
If the slope of a line is m, then the slope of the perpendicular line to it is [tex]-\frac{1}{m}[/tex]To find the slope of a perpendicular line to a given line reciprocal the slope of the given line and change its signThe form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-intercept∵ The equation of the given line is y = -3x + 2
→ Compare it with the form of the equation above
∴ m = -3
→ To find the slope of the perpendicular line to it reciprocal it and
change its sign
∴ The slope of the perpendicular line to it is = [tex]\frac{1}{3}[/tex]
→ Choose all the equations that have m = [tex]\frac{1}{3}[/tex]
∴ y = [tex]\frac{1}{3}[/tex] x - 3 ⇒ 3rd answer
∴ y = [tex]\frac{1}{3}[/tex] x + 7 ⇒ 4th answer
∴ y = [tex]\frac{1}{3}[/tex] x + 3.63917 ⇒ 6th answer
∴ y = [tex]\frac{1}{3}[/tex] x ⇒ 8th answer
find the solution of the system equations.
10x-7y=-1
-2x-7y=-25
Answer:
[tex]x=2, y=3[/tex]
Step-by-step explanation:
Given equations:
[tex]10x-7y=-1[/tex]
[tex]-2x-7y=-25[/tex]
We can subtract the two equations from each other to eliminate [tex]y[/tex] to solve for [tex]x[/tex]:
[tex]10x-7y-(-2x-7y)=-1-(-25)[/tex]
[tex]10x-7y+2x+7y=-1+25[/tex]
[tex]12x=24[/tex]
[tex]x=2[/tex]
Now, we can use substitution to solve for [tex]y[/tex]:
[tex]10x-7y=-1[/tex]
[tex]10(2)-7y=-1[/tex]
[tex]20-7y=-1[/tex]
[tex]7y=21[/tex]
[tex]y=3[/tex]
∴ [tex]x=2, y=3[/tex]

Suppose it is 40° inside your refrigerator and 340° inside your oven when the power goes out. The refrigerator temperature starts rising at the rate of 5° per hour. The oven temperature starts dropping at the rate of 45° per hour.
Answer:
The temperature of both appliances is 70° after 6 hours.
At 6 hours, both temperatures will be equal
Step-by-step explanation:
Equations
Let's call
T1 = Temperature inside of the refrigerator
T2 = Temperature inside of the oven.
x = Time in hours elapsed since the power goes out.
We know the temperature of the refrigerator rises at 5° per hour. Thus the function that models its temperature is:
T1 = 40 + 5x
We are also given the oven temperature drops by 45° per hour, thus:
T2 = 340 - 45x
a) Find the value of x for both temperatures to be the same.
We equal T1 and T2:
40 + 5x = 340 - 45x
Adding 45x
40 + 5x + 45x = 340
Subtracting 40:
5x + 45x = 340 - 40
Operating:
50x = 300
x = 300/50
x = 6
At 6 hours, both temperatures will be equal
b)
The common temperature can be found by substituting x in any function:
T1 = 40 + 5x = 40 + 5(6) = 40 + 30 = 70
T2 = 340 - 45x = 340 - 45(6) = 70
The temperature of both appliances is 70° after 6 hours.

twice the number is greater than
125. What is the number?
Answer:
x > 25
Step-by-step explanation:
This question relates to algebra. We can solve this problem by creating a variable for the solution (which we will find). We will link the variable in an equation l with the information given.
So let's translate each piece of information mathematically. First, the question tells us "Three times a number." The first part uses multiplication (times) linked to our number (we will use x for our variable). So we write:
3x
The second part is "increased by twice the number" Increasing is adding (+) so we add two times the number. So:
3x + 2x
The final part says "is greater than 125" so we need to use the > sign
3x + 2x > 125
Now we can solve by collecting like terms and moving them to a different side.
5x > 125
x > 25

Answer: Jenns account has the greater simple interest rate
Step-by-step explanation: The formula for simple interest is:
Where A is the final amount after investment, P is the initial amount, r is the rate of interest and t is the time periods.
For Lindsey:
Solve for r
Lindsey simple interest was 1.2% annually
For Jenn:
Jenn simple interest was 1.5% annually
Therefore Jenns account has the highest simple interest rate.
A T-shirt design company charges your team an initial fee of $25 to

additional $8. How much does it cost you to buy 10 shirts? **Don't forget
the initial fee.**(hint: determine the equation first y = _X + __ and then
plug in 10 for x)
Answer
$305 hope this helps!!! :)
Step-by-step explanation:
(A)
Let [tex]x[/tex] be the number of T-Shirts and [tex]y[/tex] be the total costs so that the total cost is:
Total Cost= $25+ $8 times the number of T-Shirts
(B) [tex]y=25+8x[/tex]
