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
In a science test. Devi scores 16 marks more than Ali. lf
Devi obtains twice as many marks as ali find the marks Ali obtains.
Let the marks of Devi be x and Ali be y.
So, the equations:
2y = x and y + 16 = x
So,
2y = y + 16. [ because we know equals are equal to equals]
=> 2y - y = 16
=> y = 16
Check
Ali's marks are half of Devi's marks.
Devi's marks are 16 more than alis.
So, Devi's marks will be 16×2 = 32 and 32 is 16 greater than 16 (16+16=32).
The tables represent the functions f(x) and g(x).
Which input value produces the same output value for the two functions?
x = –12
x = –9
x = –6
x = –3
Answer:
x = -6 has the same output for both functions
Step-by-step explanation:
Here, we want to get the x value that has the same y-value for both functions
We can simply get this by substituting
Let’s take it one after the other
if x = -12
f(x) = 2/3(-12) + 7
= -8 + 7 = -1
2(-12) + 15 = -9
This is incorrect
for x = -9
g(x) = 2/3(-9) + 7
= -6 + 7 = 1
f(x) = 2(-9) + 15 = -3
for x = -6
g(x) = 2/3(-6) + 7 = 3
f(x) = 2(-6) + 15 = 3
So as we can see our answer is x = -6
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.

The juniors and seniors at a high school are ordering class shirts. The amounts ordered in each size are shown in the two-way frequency table below.
Small Medium Large X-Large Total
Juniors 65 84 68 23 240
Seniors 51 62 79 28 220
Total 116 146 147 51 460
Which statement is true about the information represented in the table?
A The percentage of Seniors who ordered a large shirt is greater than the percentage of students who ordered a large shirt who are also in the Senior class.
B The percentage of Seniors who ordered a small shirt is the same as the percentage of students who ordered a small shirt who are also in the Senior class.
C The percentage of Juniors who ordered a medium shirt is greater than the percentage of students who ordered a medium shirt who are also in the Junior class.
D The percentage of Juniors who ordered a medium shirt is less than the percentage of students who ordered a medium shirt who are also in the Junior class.
Answer:
it b
Step-by-step explanation:
To determine which statement is true, we need to calculate the percentages for each option and compare them and option c is correct.
Option A: The percentage of Seniors who ordered a large shirt is greater than the percentage of students who ordered a large shirt and are also in the Senior class. To calculate the percentage of Seniors who ordered a large shirt, we divide the number of Seniors who ordered a large shirt by the total number of Seniors:
Percentage of Seniors who ordered a large shirt =[tex](79 / 220) * 100 = 35.91[/tex]% To calculate the percentage of students who ordered a large shirt and are also in the Senior class, we divide the number of Seniors who ordered a large shirt by the total number of students who ordered a large shirt: Percentage of students who ordered a large shirt and are also in the Senior class [tex]= (79 / 147) * 100 = 53.74[/tex]% Since the percentage of students who ordered a large shirt and are also in the Senior class is greater than the percentage of Seniors who ordered a large shirt, statement A is false.
Similarly, we can calculate the percentages for the other options: Option B: The percentage of Seniors who ordered a small shirt is the same as the percentage of students who ordered a small shirt and are also in the Senior class. Percentage of Seniors who ordered a small shirt [tex]= (51 / 220) * 100 = 23.18[/tex]% Percentage of students who ordered a small shirt and are also in the Senior class [tex]= (51 / 116) * 100 = 43.97[/tex] % Since the percentages are not the same, statement B is false.
Option C: The percentage of Juniors who ordered a medium shirt is greater than the percentage of students who ordered a medium shirt and are also in the Junior class. Percentage of Juniors who ordered a medium shirt [tex]= (84 / 240) * 100 = 35[/tex]% Percentage of students who ordered a medium shirt and are also in the Junior class [tex]= (84 / 146) * 100 = 57.53[/tex]% Since the percentage of students who ordered a medium shirt and are also in the Junior class is greater than the percentage of Juniors who ordered a medium shirt, statement C is true.
Hence the correct option is C.

y = 2x-2
-4x-y = 26
Answer:
x = -4
y= -10

Solving for x
-4x-y = 26
-4x-(2x-2) = 26
-6x+2 = 26
-6x = 24
x = -4

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.

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!

Is this correct? Please Help!
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
