PLEASE ANSWER !!

Mathematics
1 answer:
ANEK [815]3 years ago

Answer:

Check the explanation.

Step-by-step explanation:

As the graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2.

As the slop-intercept form is given by:

y = mx+b

where m is the slope and b is the y-intercept.

substituting the values (-2, -10) and m = 5/2 in the slop-intercept form to determine y-intercept.

y = mx+b

-10=\frac{5}{2}\left(-2\right)+b

-\frac{5}{2}\cdot \:2+b=-10

-5+b=-10

-5+b+5=-10+5

b=-5

And the equation of the line in the slope-intercept form will be:

y = mx+b

putting b = -5 and slope = m = 5/2

y = mx+b

y=\frac{5}{2}x+\left(-5\right)

y=\frac{5}{2}x-5

Determining the zero of function.

As we know that the real zero of a function is the x‐intercept(s) of the graph of the function.

so let us determine the value of x (zero of function) by setting y = 0.

0=\frac{5}{2}x-5

\frac{5}{2}x-5=0

\frac{5}{2}x=5

5x=10

x=2

Therefore, the zeros of the function will be:

  • x = 2

Every integer number is also a. Irrational number b. Whole number c. Natural number d. Rational number
const2013 [10]

Answer:

Option d

Step-by-step explanation:

Other options are not eligible because

a) Integers are not irrational

b)Whole numbers start from 0 and consists positive integers only.But integers consist negative integers also.

c)Natural number consists of positive integers only.

If the question had been asked as some integers are also, then options b) and c) could have been written . But in this case , it is asked every integer is also.

Thank you!

What is the slope and y-intercept of line q graphed below?
beks73 [17]

The correct answer is C) 1/3 and (0, 1)

The y-intercept part is somewhat simple. In order for it to be a y-intercept, the x value of the ordered pair must be 0. That is only true in B and C, therefore they are the only possible answers.

To find the slope, we must choose two points on the line and use the slope formula. We can start by using the y-intercept (0, 1) and also (3, 2). Now we use the slope formula.

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

In this equation m is equal to slope, the first point is (x1, y1) and the second point is (x2, y2)

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

m = (2 - 1)/(3 - 0)

m = 1/3

Now knowing the slope, you can match this with answer C.
