To graph the equation of the line, find the x-intercept and the y-intercept of the function

we have

$y=4x+4$

we know that

The x-intercept is the value of x when the value of y is equal to zero

The y-intercept is the value of y when the value of x is equal to zero

Step 1

<u>Find the x-intercept</u>

For $y=0$

$0=4x+4$

$4x=-4$

$x=-1$

the x-intercept is the point $(-1,0)$

Step 2

<u>Find the y-intercept</u>

For $x=0$

$y=4*0+4$

$y=4$

the y-intercept is the point $(0,4)$

Step 3

Graph the points and draw the line

see the attached figure

therefore

the answer in the attached figure

The width of a rectangle is 22 inches and the perimeter is at least 165 inches. what inequality could be used to find the minimu

Lera25 [3.4K]

The answer is D.

We know that a rectangle has two widths that are equal and two lengths that are equal. One width is 22, so the other one is also 22.

If you wanted to find the lengths, you would add both widths together (same as multiplying a width by two) and add that to the two lengths equaled to the perimeter.

So, 22 * 2 + 2x = perimeter of rectangle. We added all four sides together.

We know that the perimeter is at least 165, so 22 * 2 + 2x = 165. Here's the twist. They want the most minimum possible length. So, what answer choice gives you 165 or less for the most minimum or smallest length while still getting to 165?
That is D.
22 * 2 + 2x < = 165.
Hope this helped!

What is the only unknown (variable) needed to find the volume of a sphere?

yuradex [85]

Sphere

The radius of the sphere is the only unknown variable need to find the volume of a sphere.

Step-by-step explanation:

Sphere is a geometrical three dimensional round figure with every point on its surface equidistant from its center. It is a three dimensional representation of a circle. A line which connects from the center to the surface is called radius of the sphere.The diameter of the sphere is the longest straight line which passes through the center of the sphere.

The volume of sphere is given by:

Volume of sphere(V) = $\frac{4}{3}\pi r^{3} \\$

where V is the volume of the sphere

r is the radius of the sphere

$\pi = \frac{22}{7}$ = 3.14

Hence the only unknown variable to find the volume of a sphere is the radius.

The odds of winning a rifle are 1:9 the probability of winning a carnival game is 0.15 does the raffle or the carnival game give

Lilit [14]

Answer:

Hence the carnival game gives you better chance of winning.

Step-by-step explanation:

Let the event of win be given by 1/10 in the game of rifle then the event of loose is given by 9/10

the

Odds in favor of a game are given by = P(Event)/ 1- P(Event)

Odds in favor of winning a rifle are given by = 1/10/ 1- 1/10

=1/10/9/10

=1/9

= 0.111

The probability of winning aa rifle game is 0.111

The probability of winning the carnival game is 0.15

Comparing the two probabilities 0.111:0.15

The probability of winning carnival game is greater than winning a rifle game

0.15>0.11

Hence the carnival game gives you better chance of winning.
