Answer:
x = 4, y = -10
Step-by-step explanation:
if both expressions equal 'y' then you can solve by setting them equal to each other:
-5x + 10 = -2x - 2
-3x + 10 = -2
-3x = -12
x = 4
find 'y':
y = -5(4)+10
y = -20 + 10
y = -10

405 gallons of water in the tank in 45 minutes.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
Given that A water tank is filled with a hose.
The table shows the number of gallons of water in the tank compared to the number of minutes the tank was
being filled.
The line of best for this data is g = 9m - 0.17.
We need to find when it is 45 minutes.
We have to put m value as 45 to find the number of gallons
g=9(45)-0.17
g=405-0.17
g=404.83
Hence, 405 gallons of water in the tank in 45 minutes.

Answer:
y = -1
Step-by-step explanation:
1) first, you would have to substitute x, the input, with 30, y = 14-0.5(30)
2) then, you would multiply 0.5 and 30 together which gets y=14-15
3) lastly, 14-15 equals -1 so y = -1
Answer:
Answer is -1
Step-by-step explanation:
First we know that x = 30, and in 0.5x we can plug in 30 because x = 30. So the equation is 14 - 0.5(30), now multiply 0.5 * 30 which will give you 15. Now the new equation is y = 14 - 15, 14 - 15 will give you -1. And that is y, Y = -1

Answer:
x = 6
y = 6[tex]\sqrt{2}[/tex]
z = 12
Step-by-step explanation:
the ratio of sides in a 30-60-90° triangle is, respectively, 1 : [tex]\sqrt{3}[/tex] : 2
therefore, 'x' must have a measure of 6
which means the hypotenuse must have a measure of 12
other triangle is a 45-45-90° triangle whose sides are in a ratio of 1 to [tex]\sqrt{2}[/tex]
this means that 'y' must be 12/[tex]\sqrt{2}[/tex] which is 6[tex]\sqrt{2}[/tex]
'z' must be 6[tex]\sqrt{2}[/tex] · [tex]\sqrt{2}[/tex] = 12

The vertices of ΔJKL are J(–3, –2), K(1, 4), and L(4, 2). Which coordinate pairs are vertices of D5(ΔJKL)? Select all that apply.
Answer:
J' = (-15, -10)
K' = (5, 20)
L' = (20, 10)
Step-by-step explanation:
Given the coordinates J(–3, –2), K(1, 4), and L(4, 2)
D5(ΔJKL) means we need to dilate the coordinates by a constant of 5
To do that, we will multiply the coordinates by a value of 5
D5(ΔJKL)
J' = (5(–3), 5(–2)),
J' = (-15, -10)
K' = (5(1), 5(4))
K' = (5, 20)
L' = (5(4), 5(2))
L' = (20, 10)

About 1 liter of water is left in a water cooler. How much water was in the cooler when it was full
Answer:
Step-by-step explanation:
The amount of water that was in the cooler initially is dependent on the amount of water in the cooler now(that is, what is remaining). And also, the rate of which water was being used. If the rate at which water was being used was 10 liter/hour, this means that an 11 liter cooler would remain 1 liter after an hour. Because 10 liters must have been used within the said hour.
Answer:
10 liters

A triangle has one side which is 2 meters long and another side which is 5 meters
long. Write a value that could be the length of the third side, in feet.
Answer:
23 feet > m ; or m must be less than 23 feet.
Step-by-step explanation:
Let's call this final, or third side, m.
According to the Triangle Inequality Theorem, or the Gator Theorem - as some call it - "The sum of the lengths of any two sides of a triangle is greater than the length of the third side."
So,
[tex]2+5>m\\7>m[/tex]
So, we know that m must be less than 7 meters! However, we are NOT done. We must convert M's measurement of meters into feet.
A meter is about 3.28 feet, so using that conversion...
[tex]3.28 * 7 = 22.96\\[/tex]
That is about 23 feet :)
