Liula [17]3 years ago

Answer:

Step-by-step explanation:

eq1.    x + 2y = 11

eq2.   6x + 4y = 34

------------------

Objective is to eliminate one of the variables, either x or y.

Let's eliminate y by multiplying the top equation with the number 2.

2x +4x = 22

Now multiply the bottom equation by -1

2x +4x = 22

-6x -4x = -34

------------------

Now add both equation and you will see that y will be eliminated.

So therefore, the answer is A.2

what is the equation of the line that is parallel to 6x-2y=4+6y and passes through the point (8, -16)?
Alisiya [41]

Answer:

y=\frac{3}{4}x-22

Step-by-step explanation:

We are given;

  • The equation of a line 6x-2y=4+6y
  • A point (8, -16)

We are required to determine the equation of a line parallel to the given line and passing through the given point.

  • One way we can determine the equation of a line is when we are given its slope and a point where it is passing through,

First we get the slope of the line from the equation given;

  • We write the equation in the form y = mx + c, where m is the slope

That is;

6x-2y=4+6y

6y + 2y = 6x-4

8y = 6x -4

We get, y = 3/4 x - 4

Therefore, the slope, m₁ = 3/4

But; for parallel lines m₁=m₂

Therefore, the slope of the line in question, m₂ = 3/4

To get the equation of the line;

We take a point (x, y) and the point (8, -16) together with the slope;

That is;

\frac{(y--16}{x-8}=\frac{3}{4}

4(y+16)=3(x-8)\\4y + 64 = 3x - 24\\4y=3x-88\\ y=\frac{3}{4}x-22

Thus, the equation required is y=\frac{3}{4}x-22

An 8-oz bottle of ketchup costs $1.39.
inna [77]
First, you need to find how much an ounce costs. To do that, you have to divide 1.39 by 8. Then you get about 0.17. Now, you multiply 0.17 by 14, and get the answer of 2.38. Therefore, a 14-oz bottle of ketchup costs $2.38.

NO LINKS !!! What are the measures of 21, 22, and 23? Enter your answers in the boxes.
frosja888 [35]

Answer:

4= 61+60=121

180-121=59

m<4= 59°

3=180-61= 119

m<3= 119°

2=180-119=61

m<2= 61°

1=61+60=121

180-121= 59

m<1= 59°

hey, I hope this was helpful:)
