Find the slope by using 2 sets of x,y values from the table.
Slope is change in y over change in x:
Slope = (-6 - -9) / (1 - -2) = 3/3 = 1
Then the y intercept is the value of y when x is 0. Looking at the table when x is 0 y is -7
The equation would be y = x-7

Solve the following system of equations using substitution.
y = 2x-2
-4x-y = 26
Answer:
x = -4
y= -10
Step-by-step explanation:
Solving for x
-4x-y = 26
-4x-(2x-2) = 26
-6x+2 = 26
-6x = 24
x = -4
Solving for y
y = 2x-2
y = 2(-4) -2
y= -8-2
y = -10

Compare 6 ⋅ 108 to 3 ⋅ 106
6 ⋅ 108 is 2,000 times larger than 3 ⋅ 106.
6 ⋅ 108 is 200 times larger than 3 ⋅ 106.
6 ⋅ 108 is 20 times larger than 3 ⋅ 106.
6 ⋅ 108 is 2 times larger than 3 ⋅ 106.
Answer:
6 ⋅ 108 is 2 times larger than 3 ⋅ 106.
(6 x 10^8) ÷ (3 x 10^6) = 200
So the answer is 6 ⋅ 10^8 is 200 times larger than 3 ⋅ 10^6.

Richard and Linda enjoy visiting Hilton Head Island, South
Carolina. The distance from their home to Hilton Head is
975 mi, so the drive takes them 2 days. Richard and Linda
travel twice as far the first day as they do the second day.
How many miles do they travel each day?
Answer:
first day: 650, second day: 325
Step-by-step explanation:
Let x be the number of miles travelled on the second day and 2x the number of miles travelled on the first day. They add up to 975.
2x+x=975
3x=975
x=325
x represents the number of miles travelled on the second day so they travelled 650 miles on the first day and 325 miles on the second day.
Answer:
650 miles the first day, 325 miles the second day
Step-by-step explanation:
We can call the distance they traveled on the first day as 2x and the distance they traveled on the second day as x. The former is 2x because they traveled twice as far the first day compared to the second day. Since the total distance traveled is 975 miles, we can write the following equation to solve for x:
[tex]2x + x = 975[/tex]
[tex]3x = 975[/tex] (Simplify LHS; 2x + x = 3x)
[tex]\frac{3x}{3}=\frac{975}{3}[/tex] (Divide both sides of the equation by 3 to get rid of the coefficient on x)
[tex]x = 325[/tex] (Simplify)
Therefore, [tex]2x = 2 * x = 2 * 325 = 650[/tex] so the final answer is they traveled 650 miles the first day and 325 miles the second day. Hope this helps!

Step-by-step explanation:
Reba works at a starbucks coffee shop where a 120z cup of coffee costs $1.65, a 160z cup costs $1.85, and a 20oz cup cost $1.95. During one busy period, Reba served 55 cups of coffee, emptying six 1440z brewers while collecting a total of $99.65. How many cups of each size did reba fill?
Answer:
Cups of 120oz sold = 17
Cups of 160oz sold = 25
Cups of 200oz sold = 13
Step-by-step explanation:
We know that:
a 120z cup of coffee costs $1.65
a 160z cup costs $1.85
a 200oz cup cost $1.95
Let's define the variables:
A = # of 120z cups that she sold
B = # of 160oz cups that she sold
C = # of 200oz cups that she sold.
We know that:
"Reba served 55 cups of coffee"
A + B + C = 55.
"emptying six 1440z brewers while"
A*120oz + B*160oz + C*200oz = 6*1440oz
"collecting a total of $99.65"
A*$1.65 + B*$1.85 + C*$1.95 = $99.65
Then we have a system of equations:
A + B + C = 55
A*120oz + B*160oz + C*200oz = 6*1440oz
A*$1.65 + B*$1.85 + C*$1.95 = $99.65
To solve this, the first step is to isolate one of the variables in one of the equations, let's isolate A in the first one:
A = 55 - B - C
Now we can replace that into the other two equations:
(55 - B - C)*120oz + B*160oz + C*200oz = 6*1440oz
(55 - B - C)*$1.65 + B*$1.85 + C*$1.95 = $99.65
Now we can rewrite those equations as:
B*40oz + C*80oz = 8640oz - 55*120oz = 2040oz
B*$0.20 + C*$0.30 = $99.65 - 55*$1.65 = $8.90
Now we have the system:
B*40oz + C*80oz = 2040oz
B*$0.20 + C*$0.30 = $8.90
Now we need to isolate another variable in one of the equations, let's isolate B in the first one:
B = 2040oz/40oz - C*80oz/40oz = 51 - 2*C
Now we can replace this in the other equation and get:
(51 - 2*C)*$0.20 + C*$0.30 = $8.90
Bow we can solve this for C.
$10.20 - C*$0.40 + C*$0.30 = $8.90
$10.20 - $8.90 = C*$0.10
$1.30 = C*$0.10
($1.30/$0.10) = C = 13
Now we can replace this in the equation:
B = 51 - 2*C = 51 - 2*13 = 25
And for A, we had:
A = 55 - B - C = 55 - 25 - 13 = 17
Then:
Cups of 120oz sold = 17
Cups of 160oz sold = 25
Cups of 200oz sold = 13
Ricardo borrows $1850 for 8 months at 12% interest.
What is the amount he will pay back at the end of the
loan period?
How do you know?
Answer:
Ricardo will have to pay $1776 at the end of the loan period.
I know this because if you multiply 12% to 1850 you get 222.
Now you multiply 222 to 8 which gives you an answer of 1776.
Hope this helps. :)
