Solve the system of equations..
y=x +45
y= 5x + 13
Answer:
x = 8
y = 53
Step-by-step explanation:
Sub y = x + 45 into the second equation
x + 45 = 5x + 13
Rearrange by collecting the like terms
45 - 13 = 5x - x
32 = 4x
Divide both sides by 4
x = 8
Sub x = 8 into first equation (y = x + 45)
y = 8 + 45
y = 53

in and her brother each created a scale drawing of the backyard, but at different scales. Lin used a scale of 1 inch to 1 foot. Her brother used a scale of 1 inch to 1 yard. Express the scales for the drawings without units.
Whose drawing is larger?
Answer:
Lin's drawing is larger.
Step-by-step explanation:
Say that their backyard is 1 yard, her brother's scale drawing would only be 1 inch, but Lin's scale drawing would be 3 inches. From this you can take away that the smaller the scale the bigger the scale drawing, (does that sentence make any sense?)
the scale of a map says that 1 cm represents 5 km. what distance on the map (in centimeters) represents an actual distance of 45 kilometers?
Answer:
Step-by-step explanation:
1cm = 5km
?cm = 45km.
Solve by dividing 45 by 5.
If the distance is 45km, on the map this will be 9cm.

Answer:
-1/2
Step-by-step explanation:
multiply (3-6i)^2 write in standard form
-27-36i .................................................................... not sure
The result of (3 - 6i)² will be -27 -36i .
Given,
(3 - 6i)²
Now,
The multiplication is of complex number .
So,
(3-6i)(3 - 6i)
So,
Multiply the terms ,
9 - 18i - 18i -36
Simplifying further,
-27 - 36i
Thus the resultant will be -27 -36i .

Answer:
1, 210.
2. 72 minutes.
3. 42 minutes
4. 2 inches.
5. 3 cents.
Step-by-step explanation:
1. First, divide 240 by 8, which will get you 30, now multiply 30 by 7 and you will get 210 which is your answer.
2. Your keyword here is times. So you know you will multiply. So just multiply 8 and 9, and your product is 72, so 72 minutes.
3. Multiply 3 1/2 by 12, or convert your fraction to a decimal, which in decimal form is 3.50. Your product would be 42.
4. Multiply 1/7 by 14, you should get 14/7, which is an improper fraction. Divide 14 by 7 and you will get 2 inches.
5. So here you have to find the unit rate. Divide the price by the quantity.
4.86/16.2=0.297530865
Round the number up, which would be 3. So it would be 3 cents
Hope this helps :)

The Y- intercept form from the line whose slope is 2 and passes through (-7,11)
Answer:
y = 2x + 25
Step-by-step explanation:
Slope-Intercept Form: y = mx+b
Slope: m = 2
y = 2x + b
Solve for b:
y = 2x + b
11 = 2(-7) + b
11 = -14 + b
b = 25
y = 2x + 25

2. $294, $150, $175, $450
Step 2 Initial value/y-intercept = /answer options
1. $150, $450, $575, $350
Step 3: Slope intercept form :
y=450x + 575
y=294x + 450
y=150x + 575
y=450x + 150
Answer:
$150, $575, y=150x+575
Step-by-step explanation:
hi! the first answer is $150 because the slope is the change in y values divided by the change in x values.
(1625-1175)/3 = 150
the second answer is $575 because the y-intercept is the y value at x=0. the savings amount increases by 150 every month, so to get to 0, we multiply 150 by 4, which is 600. we subtract this from 1175, which is 575.
the third answer is y=150x+575 because the initial amount (y-intercept) is 575 so it is constant, and it increases by 150 every month (therefore accompanied by a variable).

Answer:
Y=112 x=45
Step-by-step explanation:
y+68=180
so 180-68=112
y=112
y+(4x-2)+30=180
112+(4x-2)+30=180
140+4x=180
-140 to both sides
4x=180
divide by 4 to both sides

Simplify your answer as much as possible.
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The first step you should take is to distribute the 2, so if you do that it'll leave you with... [tex]12=-4v+2v+4[/tex]
Then you notice the like terms and then you have to combine them and that'll give you... [tex]12=-2v+4[/tex]
Now you subtract the 4 to both sides and get... [tex]8=-2v[/tex]
Lastly the fun step is to divide the -2 to both sides and to get the answer of...
[tex]v=-4[/tex]
