Answer:

(- 4, 1 )

Step-by-step explanation:

Given the 2 equations

2.5x - 3y = - 13 → (1)

3.25x - y = - 14 → (2)

Multiplying (2) by - 3 and adding to (1) will eliminate the term in y

- 9.75 + 3y = 42 → (3)

Add (1) and (3) term by term

- 7.25x = 29 ( divide both sides by - 7.25 )

x = - 4

Substitute x = - 4 in either of the 2 equations and solve for y

Substituting in (1)

- 10 - 3y = - 13 ( add 10 to both sides )

- 3y = - 3 ( divide both sides by - 3 )

y = 1

Solution is (- 4, 1 )

A line passes through the point (-7, 5) and has a sloe of 1/2. Which is another point that the line passes through?
Mekhanik [1.2K]

The point through which the same line is passing will be (9,13) so option (C) will be correct.

<h3>What is a line segment?</h3>

A line section that can connect two places is referred to as a segment.

A line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

The equation of any line with slope m can be given as

y = mx + c

Given,

slope m = 1/2

Point of passing  (-7, 5)

So,

5 = -7/2 + c ⇒ c = 17/2

So the equation will be,

y = x/2 + 17/2

2y = x + 17

Now checking all points (9,13) is satisfying.

2(13) = 9 + 17

26 = 26

Hence point (9,13) is passing through the line.

Explain why the function of f(x)=4x^2+8x is neither even or odd
myrzilka [38]

Answer:

By putting x = -x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.

Step-by-step explanation:

We need to explain why the function of f(x)=4x^2+8x is neither even or odd

First we will understand, when the function is even and odd

Even function:

<em>A function is even if f(-x) = f(x) </em>

Odd function:

<em>A function is odd if f(-x) = -f(x) </em>

So, if we get the above result by putting x = -x, then we can say that the function is even or odd.

If we don't get any of the above results then the function is neither even nor odd.

So, for the given function: f(x)=4x^2+8x

Put x = -x

f(x)=4x^2+8x\\Put x=-x\\f(-x)=4(-x)^2+8(-x)\\f(-x)=4x^2-8x

So, by putting x=-x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.
