Answer:
Y=4X-5
Step-by-step explanation:
The Slope is a positive 4 so you will already have the equation Y=4X and the y-intercept is the Y when X is at the origin. Since the y-intercept is negative you have to subtract from the slope instead of adding. Then you get Y=4X-5.
She had $3000. She spend 40% of the money in smart TV and 15% of the remainder on Game Set. (a) What % of the money had she left? (b) How much money had she left?
Answer: She had left 54% of the money which is $1620.
Step-by-step explanation:
40% of $3000 = $1200
15% of $1200 = $180
$3000 - ($1200 + $180)
$3000 - $1380 = $1620
$1620 is the money she had left.
$1620 is 54% of $3000
She had 54% left of the money.

Lin says that a snack machine is like a function because it outputs an item for each code input. Explain why Lin is correct.
Lin is correct.
What is a function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable, is called its function.
Given that, Lin says that a snack machine is like a function because it outputs an item for each code input.
Lin is correct because, function tells the relation between an output to its input.
A function is a relation from the set of the inputs to a set of all possible outputs, where each input is related to exactly one output.
So Lin's opinion about snack machine is correct as the snack machine is output an item for each code input.

There are 15 boys and 45 girls competing in a race. What is the ratio of girls to boys in the race , lowest terms ?
==========================================
Work Shown
45 girls : 15 boys
45/15 girls : 15/15 boys .... divide both parts by 15
3 girls : 1 boy
This tells us there are three times as many girls as there are boys.
We write this as the ratio 3 : 1. The order of the terms is important. We cannot say 1:3 since that would imply there are more boys than girls, but it's the other way around.

The only Pythagorean triple that is three integers in sequence is 3, 4, 5.
2, 3, 4 is not a Pythagorean triple (will NOT form a right triangle).

A 2-3-4 triangle is an obtuse triangle.
is 9.521521521 rational or irrational
If the numbers after the decimal terminate, yes, it's rational.
9.521521521 = 9,521,521,521 / 1,000,000,000
If they don't terminate, but the pattern continues (which I suspect is the case here), yes, it's still rational.
If x = 9.521521521…, then
1000x = 9521.521521521…
Subtract x from this to eliminate the fractional part:
1000x - x = 9521.521521521… - 9.521521521…
999x = 9512
x = 9512/999
If they don't terminate, but the pattern does not continue, meaning the next few digits could be something random like
9.52152152119484929271283583457…
then the number would be irrational.

Answer:
360 for first place and 240 for second
Step-by-step explanation:
Let's say f is the first place prize, and s is the second prize.
Amaal: 4f + 2s = 1920
Brian: f + 3s = 1080
Now we can isolate and substitute.
f = 1080 - 3s
4(1080 - 3s) + 2s = 1920
4320 - 12s + 2s = 1920
10s = 4320 - 1920
10s = 2400
s = 240
f = 1080 - 3*240
= 1080 - 720
= 360

Garrett arrived at the train station at 12:35 P.M. His train finally came at 1:30 P.M. How long
did Garrett have to wait for the train?
Answer:
55 minutes
Step-by-step explanation
He started waiting at 12:35 P.M. If we're assuming this is the same day, you're able to add the minutes until you get to 1:00 P.M., which is around 25 minutes. Afterwards, you need to add another 30 minutes to get to the train's time of arrival, which means you should get 55 minutes!

Which equation best represents the line? (4 points)
a
y = 1 over 3.x − 1
b
y = 3x − 1
c
y = −x + 1 over 3.
d
y = 3x + 1
Answer:
The equation of the line is y = 3x - 1 ⇒ b
Step-by-step explanation:
From the given graph
∵ The rule of the slope of the line is m = [tex]\frac{y2-y1}{x2-x1}[/tex]
∵ (x1, y1) and (x2, y2) are two points on the line
∵ The line passes through points (0, -1) and (1, 2)
∴ x1 = 0 and y1 = -1
∴ x2 = 1 and y2 = 2
→ Substitute them in the rule of the slope to find it.
∵ m = [tex]\frac{2--1}{1-0}[/tex] = [tex]\frac{2+1}{1}[/tex] = [tex]\frac{3}{1}[/tex]
∴ m = 3
∵ The line intersects the y-axis at point (0, -1)
∴ The y-intercept = -1
∵ The form of the equation of the line is y = m x + b
∵ b is the y-intercept
∴ b = -1
→ Substitute the values of m and b in the form of the equation
∵ y = 3x + -1
∴ y = 3x - 1
∴ The equation of the line is y = 3x - 1

Answer:
The third angle would measure 80 degrees
Step-by-step explanation
The equal measure of each angle in a triangle adds up to 180 degrees. The first two angles of 70 and 30 equal 100. Thus, the third angle will measure out to be 80 degrees. Have a great day!

Answer: the answer to this is 9 miles an hour
Step-by-step explanation: 1. What this is asking is to make the fraction a bit easier to understand. So all we do is divide the numerator by the denominator. You can use this method for any other math problems like this also.
2. All this chart is doing is multiply the input or output by 9. If you look you can see the hours is multiplied by nine. I hope this helped.
