Answer:

(2, -1)

Step-by-step explanation:

We can add the first equation by the second

(4x + 6y = 2)+(-4x + 4y = -12)=

10y=-10

we divide both sides by 10 to get

y=-1

We plug -1 in the second equation to get:

-4x+4(-1)=-12

-4x-4=-12

-4x=-8

Now, we divide both sides by -4

x=2

Hope this helps!

The tables show linear relationships between x and y. Write an equation in slope-intercept form for each relationship.
Alenkinab [10]
The first thing you need to do is calculate the slope. pick 2 of the ordered pairs.

i'll use (1, 4) and (0, 6)

m = (6 - 4)/(0 - 1)
m = (2)/(-1)
m = -2

so the slope is -2. slope intercept form is written as y = mx + b and you have one part of that equation

y = -2x + b

to find b, use one of the selected points. i'll use (0, 6).

(6) = -2(0) + b
6 = b
b = 6

therefore:

y = -2x + 6

Patios can be made by mixing cubic meters of cement, gravel, and stones in the ratio 9:4:6. How much gravel is needed to make 20
LenKa [72]

Answer:

44 cubic meters

Step-by-step explanation

9 + 4 + 6 = 19

9/19 of the patio will be cement

4/19 of the patio will be gravel

6/19 of the patio will be stones

Work out the amount of gravel - 4/19 * 209 = 44 cubic meters

Gabe is planning on riding the roller coaster 25 times. If he has already ridden 36% of his 25 times, how many times has Gabe al
AVprozaik [17]
If you do 25 x X = 100
It would be x = 4
So we would divide 36% by 4 to get how many times he rode, which is 9
So he already has ridden 9 times.
