3x + 2y = 14. X + y = 5. Work put the values of x and y
andrey2020 [161]

Answer:

x = 4 , y = 1

Step-by-step explanation:

3x + 2y = 14 → (1)

x + y = 5 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate the y- term

- 2x - 2y = - 10 → (3)

Add (1) and (3) term by term to eliminate y

x = 4

Substitute x = 4 into (2) and evaluate for y

4 + y = 5 ( subtract 4 from both sides )

y = 1

What is the point slope of an equation with slope of 3/5 that passes through the point (10,-2)
Verdich [7]
The answer would be B. It gives you the slope and a point on the graph so use that to your advantage. All of the answers show the slope and the slope in the right place, so for now it can be any of them. Then we get to the point (10,-2). For point slope form you would switch the signs for both x and y. So the Y would now be +2 and x would be -10. Y goes together with y, and X goes together with x. In this case y+-y= slope(X+-x) Substitute in for them. Y+2=3/5(X-10)

A public swimming pool that holds 45,000 gallons of water is going to be drained for maintenance at a rate of 100 gallons per mi
crimeas [40]

Answer:

450 minutes

Step-by-step explanation:

Given

w = 45000 - 100t

Required

Determine how long it'll take to empty the pool

Being empty means there's no water in the pool.

So, we have to set w to 0 to get the value of t

i.e w = 0

Substitute 0 for w in w = 45000 - 100t

0 = 45000 - 100t

Collect Like Terms

100t = 45000

Divide through by 100.

t = 450

Hence, it'll take 450 minutes to empty the pool

Write the conversion factor for converting meters to centimeters
posledela
Since we are converting meters to centimeters we are converting large to small.

Expect the answer to be a larger number.  Here are some example of large to small:
2 weeks (larger unit) = 14 days (smaller unit)   14 is larger than 2
4 days (larger unit )  = 96 hours (smaller unit)  96 is larger than 4
Since there are 100cm in a meter, when we change meters to cm, we need a bigger number.  The conversion factor is 100 and should be used as a multiplier.
Example:  47m x 100 = 4700 cm
