Answer: See below

Explanation:

3x - 4y = 13 (1)
2x + y = 5 (2)
——————
3x - 4y = 13
4(2x + y = 5) (2) times 4
——————-
3x - 4y = 13
8x + 4y = 20
——————-
11x = 33
x = 33/11
x = 3

Plug x = 3 in (2):

2(3) + y = 5
6 + y = 5
y = 5-6
y = -1

Thus, x = 3 and y = -1

Rewrite the expression 10 to the -3 power
liberstina [14]

Answer: 0.001 or 1/1000

Since it is a negative exponent and -3 so it is in the thousandths, so 1/1000 or 0.001.

Have a good day! : )

Given the following linear functio, determine the slope of a line parallel to f(x)
andrew11 [14]

Answer:

Option C is correct.

C. 4/3

Step-by-step explanation:

Given:

The given linear function of a line.

F(x)=4/3x+2

We need to determine the slope of a line parallel to F(x)=4/3x+2

Solution:

First we compare the given function of the line with standard form of a line. y = mx + c

Where m = slope of the line.

And c = y-intercept

So, the slope of the line m=\frac{4}{3} and y-intercept c=2

We know that the slope of the parallel lines are same.

Therefore, the slope of a the parallel line m=\frac{4}{3}.

Find the slope of the line passing through the points (-4,-4) and (2,5)​
Advocard [28]

Answer:

3/2

Step-by-step explanation:

Use the slope formula:

m = (y2-y1)/(x2-x1)

m = (5-(-4))/(2-(-4))

m = 9/6

m = 3/2

Find the xx-intercept of each line defined below and compare their values.
alexandr1967 [171]

Answer:

\displaystyle greater\:than \\ Line\:B: [-6, 0] \\ Line\:A: [2, 0]

Step-by-step explanation:

The x-intercept of Line B is already given to you because it is where the graph intersects the x-axis.

Now, to get the x-intercept of Line A, plug 0 in for <em>y</em><em> </em>to get this:

0 = −2x + 4

- 4 - 4

_____________

\displaystyle \frac{-4}{-2} = \frac{-2x}{-2} \\ \\ 2 = x

So, the x-intercept of Line A is \displaystyle [2, 0],and since 2 is greater than −6, <em>greater than</em> would be your answer.

I am joyous to assist you anytime.
