Solve the Systems of Equation using Substitution y=x-4 4x - 6y=-16​

Mathematics
1 answer:
Alborosie3 years ago
3 0

Answer:

x=20 and y=16

Step-by-step explanation:

4x - 6y= -16

since y=x -4, we substitute it in place of "y"

Then, 4x - 6(x-4) = -16

4x - 6x + 24 = -16

-2x+24= -16

-2x= -16-24

-2x= -40

Divide both sides by -2 then,

x=20

once we get the value of "x" we substitute in place of "y=x-4"

y=20-4

y=16

What’s 45 divided by 14.04
Vladimir79 [104]

Answer:

3.205

Step-by-step explanation:

convert the decimal number to a fraction

45 \div  \frac{351}{25}

To divide by fraction, multiply by the reciprocal of that fraction

45 \times  \frac{25}{351}

Reduce the numbers with the greatest common divisor 9

5 \times  \frac{25}{39}

Calculate the product

\frac{125}{39}

Now turn it to a decimal which will be

The equation of line p is y = x − 1 .
NeX [460]

Answer:

Step-by-step explanation:

The equation of a straight line can be represented in the slope intercept form as

y = mx + c

Where

m = slope = (change in the value of y in the y axis) / (change in the value of x in the x axis)

The equation of the given line p is

y = x - 1

Comparing with the slope intercept form, slope = 1

If two lines are parallel, it means that they have the same slope. Therefore, the slope of line q passing through (- 2, 8) is 1

To determine the y intercept, we would substitute m = 1, x = - 2 and

y = 8 into y = mx + c. It becomes

8 = 1 × - 2 + c

8 = - 2 + c

c = 8 + 2 = 10

The equation becomes

y = x + 10

A color printer prints 21 pages in 9 minutes. How many pages does it print per minute? Round your answer to the nearest hundredt
hichkok12 [17]

Answer:

2.33 = x

Step-by-step explanation:

pages minutes

21 9

x 1

Cross multiply.

21×1 = 9×x

<u>21</u><u> </u> <u>9x</u>

9 9

9 cancels 9 leaving x. and 21 divided by 9 equals 2.33 pages. NB. both sides are divided by 9 because we want x by itself and what you do to one side, you have to do to the other.

Elza [17]

Answer:

Step-by-step explanation:I would make them make all of them into a decimal or fraction that's how I do it like this       5/2   .45     27.5%

make them into a decimal this time because it looks easy so 5/2 into a decimal will be 2.5. and then 0.45   27.5% into a decimal will be will be 0.275

boom order it         2.5,  0.45,  0.275
