Answer:
x = -3.3333333
y = -2.666666
Step-by-step explanation:
y = 1/2 x - 1
y = 2x + 4 The second equation has the 2x moved to the right side. The y's must be equal so equation the two equations.
1/2x -1 = 2x + 4 Subtract 1/2x from both sides.
-1 = 2x - 1/2 x + 4 Combine
-1 = 1.5x + 4 Subtract 4 from both sides
-1 - 4 = 1.5x
- 5 = 1.5x Divide both sides by 1.5
-5/1.5 = x
x = - 3.333333
Now put x = - 3.333333 into either one of the two given equations. The first one will require one less step, but it does not matter.
y = 1/2 (- 3.3333333) - 1
y = - 1.6666666 - 1
y = -2.6666666

Write an equation for the description.
The length of a rectangle is twice its width. The perimeter of the rectangle is 134 feet.
Answer:
L = 2w 134 = 2L + 2w
l= length
w=width
l=2w
P=Perimeter= 134 ft
P= 2(l+w)
= 2(2w+w)
= 2(3w) = 6w=134
w=134/6=22 1/3 ft
l= 2w = 2 x 22 1/3 = 44 2/3 ft

Find the inverse of the following function g(x) = 2x+10/4
Answer:
Step-by-step explanation:
To find the inverse of the function you need to swap x and y
g(x)=y so therefore if you switch x and y, you get
x= 2y+ 10/4
Next, you need to get all of the values on the y side over to the x side. To do this you need to subtract 10/4 from the y side of the equation.
x-10/4=2y+10/4-10/4
The end product of this should be... (This is not your answer)
x-10/4=2y
Now you need to get rid of the 2 on the y side. To do this you need to divide both sides of the equation by 2
2/x-10/4=2y/2
So your answer is...
x-10/4 over 2 = y
OR
2/x + 5/4 = y

5x-6y=4 (Slope intercept form)
Answer:
y = 5x/6 + -2/3
Step-by-step explanation:
To put this equation into slope intercept form, we simply need to solve for the y variable like so:
5x - 6y = 4
-6y = 4 - 5x
y = (4/-6) + (-5x / -6)
y = 5x/6 + -2/3

. Joseph tweets 1 3 times a day. Define each variable and write an algebraic expression to describe the number of posts after any given number of days
Given :
Joseph tweets 13 times a day.
To Find :
An algebraic expression to describe the number of posts after any given number of days.
Solution :
Let, number of tweets after x days are y.
Let, the relationship is , y = mx + c.
For, x = 1
13 = m +c ...... 1)
x = 2
26 = 2m + c .......2)
So, m = 13 and c = 0.
Therefore, algebraic expression to describe the number of posts after any given number of days is y = 13x.
Hence, this is the required solution.

Donis bought a t-shirt for $15 and jeans for $35.50. If the sales tax rate is 8.25%. What is the sales tax for the t-shirt and jeans in dollars and cents? *
====================================================
Explanation:
15+35.50 = 50.50 dollars is the total before tax is applied.
Take 8.25% of this to get
0.0825*50.50 = 4.16625
and this rounds to 4.17, which is the amount of sales tax charged.
$4.17 = 4 dollars + 17 cents
---------
Extra info:
The grand total will be 50.50+4.17 = 54.67
Another way to get the grand total is to multiply 1.0825 by the previous subtotal (50.50) getting 50.50*1.0825 = 54.66625 and that rounds to 54.67
The multiplier 1.0825 effectively means "increase by 8.25%"

2) AC = x + 2, BC = 1, and AB = 2x - 4.
Find x, AB, and AC.
Answer:
x = 5 AB = 6 AC = 7Step-by-step explanation:
Points A, B, and C are collinear and point B is between A and C then
AB + BC = AC
2x - 4 + 1 = x + 2
2x - 3 = x + 2
+3 +3
2x = x + 5
-x -x
x = 5
AB = 2x - 4 = 2×5 - 4 = 10 - 4 = 6
