Answer:

Y=4 X= -6 or (-6,4)

Step-by-step explanation:

Okay so

3x+10y=22

-3x-8y=-14

  1. basically, it's like one big equation. First, subtract 3x from -3x which cancels out and gives us 0
  2. 10y minus 8y gives us 2y.
  3. 22 minus 14 gives us 8

3x+10y=22

<u>-3x-8y=-14</u>

0+2y=8

Now that we have this, we can solve for y. in order to do this, we have to divide both sides by 2.

\frac{2y}{2}  =  \frac{8}{2}

From here we know that y=4 because the 2s cancel out leaving y and 8 divided by 2 is 4.

y= 4

Now we can fill in. You can pick any equation for this but I'm going to chose the first one.

3x+10y=22

we can fill in 4 for y

3x+10(4)=22

3x+40=22

Next we are going to subtract 40 on both sides.

3x+40=22

-40 -40

3x= -18

Next, we're going to divide -18 by 3.

\frac{3x}{3}  =  \frac{  - 18}{3}

The 3s cancel out leaving us x. -18 divided by 3 is -6.

x= -6

Hope this helped!! :)

Suppose you are determining whether the depth of groves cut into aluminum by a milling machine is equal to 1.7 mm. You cut 14 gr
Gemiola [76]

Answer:

For this case we want to check if the true mean for the depth of groves cut into aluminium by a machine is equal to 1.7 (null hypothesis) and the alternative hypothesis would be the complement different from 1.7. And the best system of hypothesis are:

Null hypothesis: \mu =1.7

Alternative hypothesis \mu \neq 1.7[/tx]And the best system of hypothesis are:3.

Each tire on your bicycle has a diameter of 26 inches.About how far will you travel when the tires make on complete revolution?
ValentinkaMS [17]
Circumference of a circle is an equation

c = (pie) x d or ........ c = 2(pie) × r
c = 3.14 × d or ...... c = 2(3.14) x r

d is the diameter and r is radius


c = (3.14) x 26
c = 81.64 in.

What is the solution to -4|-2X +6|=-24
skad [1K]

Answer:

x=0 or x=6

Step-by-step explanation:

Step 1: Divide both sides by -4.

−4(|−2x+6|)

−4

=

−24

−4

|−2x+6|=6

Step 2: Solve Absolute Value.

|−2x+6|=6

We know either−2x+6=6or−2x+6=−6

−2x+6=6(Possibility 1)

−2x+6−6=6−6(Subtract 6 from both sides)

−2x=0

−2x

−2

=

0

−2

(Divide both sides by -2)

x=0.
