Answer:
4. Domain: -3,-2,-1,0,1, and 2. Range: -2,0,2,4,2,0. It is a function
5. Domain: -3,-1,-1,1, 2,3 Range: 0,-1,2,0,-3,3. Not a function.
Step-by-step explanation:
Number four is a function because there is one x to one y but for five there are two x's to one y.

I really don’t get this , it’s graphing linear inequalities
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).

m = y2 - y1/x2 - x1
m = (-5) - (-1)/(-4) - (-4)
m = -5 + 1/-4 + 4

If country A has 161,950,000 more computers than country B and the total number of computers for both countries is 319,250,000 find the number of computer for each country
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
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of a second.
f(x) = -16x^2+272x+110
Answer:
The time that the rocket will hit the ground will be:
x = 17.40 secondsStep-by-step explanation:
Given the expression
[tex]f\left(x\right)\:=-16x^2+272x+110[/tex]
Here:
x represents the time in secondsy represents the height of the rocketWe 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:
x = 17.40 secondsWho ever answers gets points

How to add two fractions?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

Write the ratio as a fraction in lowest terms.
Compare in inches,
2 feet to 45 inches
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.

Tamara bought yarn for $39 and 2 pairs of knitting needles. Her total cost for the yarn and knitting needles was $69. Tamara writes an equation that represents the cost of each pair of knitting needles. If k represents the cost of each pair of knitting needles, which statements about verifying the value of k are true? Check all that apply.
0) Tamara should substitute k = 30 into the equation 39 + 2 k = 69
0) After she substitutes the correct value for k into the equation, Tamara should find that the left side of the equation is equal to the right side.
0) Tamara should substitute k = 15 into the equation 39 + 2 k = 69.
0) After she substitutes the correct value for k into the equation, Tamara should find that the left side of the equation is not equal to the right side.
0) To verify the solution to the equation, Tamara multiplies the solution by 2 and then adds it to 39. Then, she checks that it is equal to 69.
0) To verify the solution to the equation, Tamara adds the solution to 2 and then adds it to 69. Then, she checks that it is equal to 39.
