A.The y-intercept of the function is 3.

Mathematics
1 answer:
Marrrta [24]3 years ago
8 0

Answer:

D. The slope of the function is positive.

Step-by-step explanation:

I think the best thing to start with is the slope. Lets figure it out using the slope formula, (y2-y1)/(x2-x1).

Using the points, (-4, -7) and (-3, -4),

(-4 - (-7)) / (-3 - (-4))

= 3 / 1

= 3

Right off the bat, you can see that C is incorrect.

Lets go through the other choices and check now.

Using our slope, lets write an equation in the slope intercept form.

y = -3x + b (derived from y=mx+b)

Now, lets plug in a point (let's say, (-4,-7)) to verify if 3 really is the y intercept.

-7 = 3(-4) + b

-7 = -12 +b

5 = b

Since 3 is not equal to 5, A is incorrect. That leaves us with choice B and D.

We know that the x-intercept is found as (0, a), meaning that this x intercept is (0, 5/3). Let's plug it into the equation!

0 = 3(5/3) + 5

0 = 5 + 5

0 = 10

Since this is obviously incorrect, our answer is D, the slope of the function is positive. Let me know if you have any other questions.

For the first figure the Circumference of the circle is: 5.3\ip\pi cm.

For the second figure the Circumference of the circle is: 80\ip\pi inch.

<h3>What is Circumference of the Circle?</h3>

The circumference of a circle is defined as the linear distance around it.

i.e.,  C= 2 *\pi*r

  • For First Figure,

Circumference of the circle:

= 2 *\pi*r

= 2 *\pi* \frac{5.3}{2}

= 2 *\pi*2.65

Circumference= 5.3*\pi cm

  • For the second Figure,

Circumference = 2 *\pi*r

= 2 *\pi*40

 = 80 *\pi

Circumference =80\pi \;inch

For the first figure the Circumference of the circle is: 5.3\ip\pi cm.

For the second figure the Circumference of the circle is: 80\ip\pi inch.

Put the following equation of a line into slope-intercept form, simplifying all
muminat

Answer:

y = 3/4 + 7

Step-by-step explanation:

you must put the equation into the form of y = mx + b

add 6x to both sides and put it in front of the 56

8y = 6x + 56

y must be by itself by x does not so we divide everything by 8

y = 6/8x + 7

we must simplify the fraction 6/8

y = 3/4x + 7

Description

DescriptionIn mathematics, a zero of a real-, complex-, or generally vector-valued function, is a member of the domain of such that vanishes at; that is, the function attains the value of 0 at, or equivalently, is the solution to the equation. A "zero" of a function is thus an input value that produces an output of

The width of a rectangle measures (7d + 8f) centimeters, and its
Andre45 [30]

The expression which represents the perimeter, in centimeters, of the rectangle is; (18d +10f) centimetres.

<h3>Perimeter of a rectangle</h3>

Since the perimeter of a rectangle is given by the formula;

  • Perimeter, P = 2l + 2w.

In essence, Perimeter, P = 2(2d – 3f) + 2(7d + 8f)

  • P = 4d -6f + 14d +16f

  • P = 18d +10f.

Ultimately, the perimeter of the rectangle is; (18d +10f) centimetres.
