Answer:
The first one is a function, the second one is a function, and the third one is not a function.
Domain for the first one, just list the x values. Same for range.
Domain and range for the second one are both all real numbers.
For the last one, solve the quadratic, and find the vertex. The range will be all numbers greater than the y on the vertex, while the domain is all real numbers.
Step-by-step explanation:
An easy way to tell if something is a function or not is to check that each input (or x-value) has a different output (or y-value.) The first one is not a function because in the table, we see that 1 gives an output of 9, but later on you see 1 also gives an output of 20.
If you're ever given a graph and asked this question, do the vertical pencil test. Start at the left of the graph, and slide your pencil over the graph (vertically) and if your pencil ever hits more than one point at a time, it's not a function. Hope this helped!

help please (: this has something to do with geometry!!
Answer: x=64°
Step-by-step explanation:
According to the diagram, the two intersecting lines are perpendicular. That means each part is 90°. Since the left side is labelled to be 180°, we know that the sum of the right side is also 180°.
26+x+90=180 [combine like terms]
116+x=180 [subtract both sides by 116]
x=64°
Now, we know that x=64°.
On the other hand, we can see that 26+x=90. We can also use that to solve for x.
26+x=90 [subtract both sides by 26]
x=64°

1. linear pair
2. Substitution Property of Equality
3. Subtraction Property of Equality
4. <1 ≅ <3
Step-by-step explanation:
1. linear pair
A linear pair is a pair of angles that that are adjacent and add to 180 degrees
linear Pair Postulate states: "If two angles form a linear pair, then the angles are supplementary.
2. Substitution Property of Equality
<1 + <2 = 180 and <2+ <3 = 180
<1 + <2 = <2 + <3
3. Subtraction Property of Equality
<1 + <2 - <2= <2 - <2+ <3
<1 = <3

Answer:
your answer should be 2 and 1/4ths
Step-by-step explanation
2 and 1/4ths bc 5 is more than 4 and there is already a whole so there for there are going to be 2 wholes then there are still parts left over and its out of 4 and there is only one left over so there for it would be 1/4ths.

−5(−8x − 8) − 4 = 5(5 + 8x) + 11 please show work
Answer:
all values of x makes the equation true
Step-by-step explanation:
-5(-8x-8)-4 = 5(5+8x)+11
40x + 40 - 4 = 25 + 40x + 11
40x + 36 = 40x + 36
all values of x makes the equation true
Please please help asap!!!! Solve for the indicated variable. 3a + 6b = 4 for b
Answer:
b = (4/6) - a/2
Step-by-step explanation:
6b + 3a = 4
6b = 4 - 3a
b. = (4 - 3a)/6
b. = (4/6) - a/2
The value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
In the provided expression, variable and constant are there
It is given that:
The equation in a and b, where a and b are the variables:
3a + 6b = 4
Here the indicated variable is b.
To find the value of b in terms of a make the subject as b:
Subtract 3a on both the sides in the equation 3a + 6b = 4:
The equation becomes:
3a + 6b -3a = 4 - 3a
6b = 4 - 3a
Divide by 6 on both sides:
The equation becomes:
6b/6 = (4 - 3a)/6
b = (4 - 3a)/6
Thus, the value of b is (4 - 3a)/6, or the equation in terms of a is (4 - 3a)/6 after making the subject as b.

Answer:
1. The radius is 90 ft.
2. 31.4 cm.
Step-by-step explanation:
1. The way to find the radius with just the diameter, is to divide by two.
2. When finding circumference, you need to multiply the diameter by 3.14 (pi), making it 10 x 3.14.
Answer:
The radius is 90
Step-by-step explanation:
the line in the middle of the circle is the diameter so in order to find the radius you need to find half of the diameter. Half of the diameter (180) is 90 90 the radius is 90.

the solution of the equation y+2=_2 is
Answer:
the answer is y= -4
Step-by-step explanation:
in this you basically just isolate the variable which means that you get rid off all the numbers that are applied to the varible by preforming the opposite opperation. In this case if you subtract 2 from both sides, the 2 on the left gets cancelled out and the -2 on the right turns into -4, so your equation would look like y=-4
What is the greatest number that will divide 307 and 330 having the reminder 3 qnd 7
Answer:
19.
Step-by-step explanation:
Answer:
The required number = 19
Step-by-step explanation:
307 - 3 = 304
330 - 7 = 323
Find GCF of 304 & 323
304 = 2* 2 *2 * 2 * 19
323 = 17 *19
HCF = 19
The required number = 19
When you divide 307 by 19, you will get an remainder 3
When you divide 330 by 19, you will get an remainder 7
A ticket to see your favorite baseball team costs $45.65. That price decreases by $0.25 for every game lost during the regular season. What equation could you use to find the cost of a ticket after L losses? Represent the total change in the cost of a ticket after the team loses 42 games. What is the price of a ticket after the team loses 42 games?
Answer:
Cost = $45.65 - $0.25L
after 42 losses:
45.65 - 0.25(42) = $35.15

Answer: (1) -3/4 (2) 7 (3) y = (-3/4)x + 7 (4) 1/2
Step-by-step explanation:
1) COUNT the number of spaces from one point to the other point.
from (0, 7) to (4, 4) is: down 3 and right 4 → m = -3/4
2) the y-intercept is where the line crosses the y-axis (when x = 0).
The line crosses the y-axis at (0, 7) → b = 7
3) Slope-Intercept form is y = mx + b
m = -3/4 and b = 7 → y = (-3/4)x + 7
4) COUNT the number of spaces from one point to the other point.
from (-2, -4) to (2, -2) is: up 2 and right 4 → m = 2/4 = 1/2 when simplified
Please just explain/show how to set up #1. I want to do the work on my own
and please someone check my work on 2 and 3
please hurry this is due in an hour and a half
Answer:
See below.
Step-by-step explanation:
We have:
[tex]\frac{\sqrt3}{\sin(\theta)}=2[/tex]
And we want to find two different angles between 0 and 180 that satisfy this equation.
First, let's get our sine out of the denominator. Notice that this is the same as:
[tex]\frac{\sqrt3}{\sin(\theta)}=\frac{2}{1}[/tex]
Cross-multiply:
[tex]2\sin(\theta)=\sqrt{3}[/tex]
Divide both sides by 2:
[tex]\sin(\theta)=\frac{\sqrt{3}}{2}[/tex]
Here you go! I'll have the answer for you if you scroll down, so check it when you're ready!
#2 is correct. However, double check #3. The answer's down there too... :)
[Blank space...]
[More blank space...]
[And more...]
Answer for 1)
We have:
[tex]\sin(\theta)=\sqrt{3}/2[/tex]
So, at what points between 0 and 180 does sine equal √3/2?
If we refer to the unit circle, we can see that this happens twice: at 60.
Thus, the second time it occurs will be at 180-60 or 120.
So:
[tex]\theta=60\textdegree\text{ or } 120\textdegree[/tex]
Answer for 3)
So you are correct for the first three. So:
[tex]\sin(54)=t[/tex]
However, sine stays positive. So, our angle must be between 0 and 180.
So, instead of 180+54, it should be 180-54, giving us:
[tex]\sin(54)=\sin(126)=t[/tex]
An airplane is flying at an altitude of 3,000 ft. The pilot dives 988 feet and then rapidly climbs 748 feet. The pilot then dives again 885 feet before making another climb of 1,099 feet.
