Hello! How are you today?

Answer:

x = -4 (and btw that is so cuteee)

Step-by-step explanation:

Points: (-4,-1) and (-4,-5)

m = y2 - y1/x2 - x1

m = (-5) - (-1)/(-4) - (-4)

m = -5 + 1/-4 + 4

m = -4/0

x = - 4

Answer:

5/32 & 5/128

Step-by-step explanation:

Answer:

it's 8

Step-by-step explanation:

The solution of the equation is y=8/3

Let we have to add two fractions as:

[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]

Then we will find Lowest Common Multiple (LCM) of   b_1 and

b_2. That will help to make the denominators same.

Once the denominators become same, the numerators can add up directly, giving us the final result of addition.

Given;

y-5/3=1

Solution;

    y=5/3+1

  or   y=5/3+1/1

  taking LCM of denominators;

           y=(5+3)/3

            y=8/3

Answer:

The number of computers in country A and country B is 78,650,000 and 240,600,000 respectively

Step-by-step explanation:

The computation of the number of computer for each country is as follows:

Let us assume the computer in country B is x

So, in country A it is x + 161,950,000

And, the sum of them is

x + x + 161,950,000 = 319,250,000

2x + 161,950,000 = 319,250,000

2x = 319,250,000 - 161,950,000

2x = 157,300,000

x = 78,650,000

So, the country B, the computers are 78,650,000

And, in country A it is 78,650,000 + 161,950,000 = 240,600,000

Answer:

The time that the rocket will hit the ground will be:

Step-by-step explanation:

Given the expression

[tex]f\left(x\right)\:=-16x^2+272x+110[/tex]

Here:

We know that when the rocket will hit the ground, the height will get y = 0

i.e.

[tex]0\:=-16x^2+272x+110[/tex]

solving for x to determine the time that the rocket takes when it will hit the ground.

so

[tex]-16x^2+272x+110=0[/tex]

subtract 110 from both sides

[tex]-16x^2+272x+110-110=0-110[/tex]

[tex]-16x^2+272x=-110[/tex]

Divide both sides by -16

[tex]\frac{-16x^2+272x}{-16}=\frac{-110}{-16}[/tex]

[tex]x^2-17x=\frac{55}{8}[/tex]

[tex]\mathrm{Add\:}\left(-\frac{17}{2}\right)^2\mathrm{\:to\:both\:sides}[/tex]

[tex]x^2-17x+\left(-\frac{17}{2}\right)^2=\frac{55}{8}+\left(-\frac{17}{2}\right)^2[/tex]

[tex]x^2-17x+\left(-\frac{17}{2}\right)^2=\frac{633}{8}[/tex]

[tex]\left(x-\frac{17}{2}\right)^2=\frac{633}{8}[/tex]

[tex]\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}[/tex]

solving

[tex]x-\frac{17}{2}=\sqrt{\frac{633}{8}}[/tex]

[tex]x=\frac{\sqrt{1266}}{4}+\frac{17}{2}[/tex]

x = 17.40 seconds

also solving

[tex]x-\frac{17}{2}=-\sqrt{\frac{633}{8}}[/tex]

[tex]x=-\frac{\sqrt{1266}}{4}+\frac{17}{2}[/tex]

x = -0.40 seconds

As time can not be negative.

Thus, the value of x = 17.40 seconds

Therefore, the time that the rocket will hit the ground will be:

Answer:

8 to 15

Step-by-step explanation:

2 feet times 12 inches is 24 and it is to 45 inches. You then need to simplify 24 and 45 by 3 to get 8 and 15 and to get the ratio 8 to 15.

Step-by-step explanation:

Answer:

6,802

Step-by-step explanation:

The first step in graphing a linear inequality is to graph the linear equality. The equation -x + 4y = -8 is equivalent to 4y = x - 8, which is equivalent to [tex]y = \frac{1}{4}x - 2[/tex]. This is the equation for the line in slope-intercept form, so the line will have a slope of 1/4 and a y-intercept of -2 (see the first image). Notice that the line is solid, rather than dotted. This represents that points on the line are included in the solution, because the inequality sign is ≥, which is not a strict equality (< or >).

Next, we need to figure out which side to shade. To do so, simply pick any point (I like to use the point (0,0) because it makes the calculations easy) and see whether it satisfies the inequality. If it does, shade the side with that point, and if not, shade the opposite side of the graph.

Here we see that the point (0,0) does satisfy the inequality, since -(0) + 4(0) is 0, and 0 ≥ -8, so the top half of the graph should be shaded (see the second image).

Answer:

66 miles per hour.

Step-by-step explanation:

Given that:

Distance between house to Wild Animal Park = 528 miles

Expected time to be taken in the travel = 8 hours

To find:

Average speed of the travel = ?

Solution:

First of all, let us have a look at the formula for Average Speed of any travel.

Let [tex]D[/tex] be the total distance traveled in any travel and

[tex]T[/tex] be the total time taken in this travel

Then Average Speed, [tex]S[/tex] is given by the formula:

[tex]S = \dfrac{D}{T}[/tex]

OR

[tex]Average\ Speed = \dfrac{Total\ Distance\ Traveled}{Total\ Time\ Taken}[/tex]

Here, we are given that:

[tex]D[/tex] = 528 miles

[tex]T[/tex] = 8 hours

[tex]S = \dfrac{528}{8}\\\Rightarrow S = \bold{66\ miles/hr}[/tex]

Therefore, the average speed is 66 miles/hr.
