Solve the system by elimination method. x+y-6=0

2 answers:

4 0

X + y - 6 = 0
Take out y.
x - 6 = 0
Add 6 to both sides.
x = 6 is your first equation.

x - y - 8 = 0
Take out y.
x - 8 = 0
Add 8 to both sides.
x = 8 is your second equation.

I hope this helps!

Answer:

The answer is x=7

and y=-1

On eliminating y the resulting equation is 2x=14

Step-by-step explanation:

Given x+y-6=0 ...........[1]

and x-y-8=0 ...............[2]

On eliminating y in eq [1]

y=6-x

Putting value of y in eq [2]

x-(6-x)-8=0

x-6+x-8=0

2x-14=0

2x=14

x=7

Putting x=7 in [1]

7+y-6=0

y+1=0

y=-1

Mrs. Nguyen used 1.48 meters of netting to make 4 identical mini hockey goals. How much netting did she use per goal?

snow_tiger [21]

0.37 meters of netting

<h3>Further explanation</h3>

<u>Given:</u>

Mrs. Nguyen used 1.48 meters of netting to make 4 identical mini hockey goals.

<u>Question:</u>

How much netting did she use per goal?

<u>The Process:</u>

We will solve the problem of conversion or in other words the ratio or proportion.

Option A: the conversion

Mrs. Nguyen used 1.48 meters of netting to make 4 identical mini hockey goals.

Then for every 1 goal, she needs 0.37 meters of netting.

Because $\boxed{ \ 1 \ goal \times \frac{1.48 \ meters}{4 \ goals} = 0.37 \ meters \ of \ netting.}$

Option B: the ratio (or proportion)

In the ratio, we process as follows:

$\boxed{ \ 4 \ goals : 1.48 \ meters \ of \ netting \ }$

Both are divided by 4.

$\boxed{ \ 1 \ goals : 0.37 \ meters \ of \ netting \ }$

Thus, she uses 0.37 meters of netting per goal.

Alternative problem

How much netting did she use for 8 goals?

$\boxed{ \ 8 \ goal \times \frac{1.48 \ meters}{4 \ goals} = \ ? \ }$ meters of netting.

We cross out eight and four because they can be divided.

$\boxed{ \ 2 \times 1.48 \ meters = 2.96 \ meters \ of \ netting. \ }$

She uses 2.96 meters of netting to make 8 identical mini hockey goals.

Please help will give brainliest if correct. What’s the equation of line a?

attashe74 [19]

Answer:

y = 14/5x + 2

Step-by-step explanation:

is seems as though the y-intercept would be 2 and the slope is 2.8 which is

2 4/5 or 14/5

therefore, equation would be y = 14/5x + 2

1.) The answer is 825.75 (multiply the given tax rates to the gross pay)
2,785 x 13% federal taxes = 362.05
2,785 x 9% state tax = 250.65
2,785 x 7.65% FICA = <u>213.05
</u> 825.75
<u>
</u>2.) The answer is 288.60 (multiply the interest rate to the balance, no need to add a late payment fee since they paid on 6/1, not after)
2,748.56 x 10.5% = 288.60

3.) The answer is 182.13  (multiply the APR to the original purchase price, no need to add the sales tax)
<u /> 1,500 x 11.75% = 182.13

4.) The answer is 371.92 (deduct the reward to the interest)
Interest : 2,975.34 x 13.5% = 401.67
Reward : 2,975.34 x 1% = <u> 29.75</u>
371.92

5.) The answer is  1,339.13 (deduct the interest to the monthly payment)
Monthly payment : 2,236.00
Monthly interest : <u> 896.87</u> [(231,450 x 4.65%) / 12 months]
<u /> 1,339.13

Hope this helps! :)
