y=-4x-9 y=3x+19

Answers

Answer:

x=-4, y=7

Step-by-step explanation:

According to the first equation, y = -4x - 9, so we can substitute y in the second equation for -4x - 9.

y = 3x + 19

-4x - 9 = 3x + 19

Add 9 to both sides

-4x = 3x + 28

Subtract 3x

-7x = 28

Divide by -7

x = -4

Plugging this into the equation, we have:

y = -4x - 9

y = -4(-4) - 9

y = 16 - 9

y = 7

Y = 500x + 38000 would be the first step, as that sets up the equation. Then, 45500 = 500x + 38000 would be the next. Third would be 7500 = 500x, as that is where we subtract 38000 from both sides. Then, finally the answer is x = 15.
To put it in a list
1. Y = 500x + 38000
2. 45500 = 500x + 38000
3. 7500 = 500x
4. 15 = x meaning 15 air conditioners must be sold

the hypotenuse of a triangle is 5in and leg one is 4in how long is leg two

Answers

So you do a^2+b^2=c^2 so hypotenuse is the longest long so it is c and other leg can be b or a it doesn’t matter as long as you have 5 for c so a^2+4^2=5^2
a^2+16=25
I squared the numbers 4times4=16 and 5times5=25
Now you minus 16 because we are trying to figure out what “a” is or other words leg two
So 25-16=9
Now a is still square so be got to take the square 2 away and square 2 is also know as square root so a= 3 the other leg is 3
Check
3^2+4^2=5^2
9+16=25
25=25

Daysi buys a video game on sale. If the video usually costs $30.00, and it
was on sale for 25% off, how much did Daysi pay?

Answers

Answer:

$22.5

Step-by-step explanation:

The original price is $30 and it's on sale for 25% off.  Since 25% is a quarter of the total price, I divided 30÷4=7.5.  $7.5 is 25% of $30, so 7.5 is the amount taken off the original price.  To find what Daysi paid, I subtracted 30-7.5=22.5.  $22.5 is the result after the 25% off, so Daysi paid $22.5.

luca sells muffins and juice boxes. muffins are $1.50 each and jucie boxes are $1.25 each. write an algebraic expression for the total income luca received from the sale of muffins and juice boxes​

Answers

Answer:

1.5m+1.25j

Step-by-step explanation:

m equals the number of muffins sold, and because each muffin sells for $1.50, 1.5m represents the income made from the muffins.

Same thing with the juice boxes, j equals the number of juice boxes sold, and because each juice box sells for $1.25, 1.25j represents the income made from the juice boxes.

Add the income from both of them to get the total income, and you get 1.5m+1.25j.

Mr. Strand mowed 2/5 of his lawn. His son mowed 1/4 of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?

Answers

Answer: Mr. Strand mowed most of the lawn, and 7/20 of the lawn still needs to be mowed.

Step-by-step explanation:

Part 1:

We can use change the fractions so that they have equivalent denominators. The Least Common Denominator that the two fractions have is 20.

2/5 = 8/20.

1/4 = 5/20.

Because of this, Mr. Strand, who mowed 2/5 of the lawn, mowed most of the lawn.

Part 2:

8/20 + 5/20 = 13/20. Therefore, 7/20 of the lawn still needs to be mowed.

In conclusion, Mr. Strand, who mowed 2/5 of the lawn, mowed most of the lawn. 7/20 of the lawn still needs to be mowed.

Answer:

Step-by-step explanation:

0.65 of the lawn was mowed

This is a bit strange how your teacher mentions the height increases at 10 inches per minute, but then doesn't refer to the time value afterward.

Ignoring that oddity, we have [tex]V = \pi*r^2*h[/tex] turn into [tex]V = \pi*4^2*h[/tex] when plugging in r = 4. This simplifies to [tex]V = 16\pi*h[/tex]

This represents the volume V for any given height h.

Let's plug in [tex]V = 80\pi[/tex] and solve for h

[tex]V = 16\pi*h\\\\80\pi = 16\pi*h\\\\80 = 16*h\\\\80/16 = h\\\\5 = h\\\\h = 5[/tex]

Note: in the jump from step 2 to step 3, I divided both sides by pi.

So we found that when the height is h = 5 feet, this leads to the volume being [tex]V = 80\pi[/tex] cubic feet.

-------------------------------

Let's convert from feet to inches

1 foot = 12 inches

5 feet = 60 inches (multiply both sides by 5)

The height of the cylinder is 60 inches when the volume is 80pi cubic feet.

We're told that the height increases by 10 inches per minute. This would mean that h = 10t assuming the height starts at 0 when the time value is t = 0.

Solving for t leads to...

h = 10t

60 = 10t

60/10 = t

6 = t

t = 6

After 6 minutes, the height is 60 inches = 5 feet.

Answers

Answer:

50 paise coin = 9

25 paise coin = 18

Step-by-step explanation:

Let :

Number of fifty paise = x

Number of 25 paise = y

50x + 25y = 900 - - - (1)

y = 2x - - - (2)

50x + 25(2x) = 900

50x + 50x = 900

100x = 900

x = 900/100

x = 9

y = 2x

y = 2(9)

y = 18
