Determine whether or not the relation is a function. Please help asap
Answer:
A function can have many x values for a given y value and still be a function but it cannot have many y values for a given x value. You can easily test this by graphing the equation and doing the vertical line test by seeing if a vertical line will intersect the graph only once at all x values, if it passes it is a function. In short what you have here is a function

Which statement about the following equation is true. 2x^2 -9+2=-1
Step-by-step explanation:
2x² - 9x + 2 = -1
2x² - 9x + 3 = 0
D = b² - 4ac
D = (-9)² - 4.2.3
D = 81 - 24
D = 57
D > 0 , so there are two real roots
Option → C
_________
[tex] \: [/tex]
2x² - 9x + 2 = -1
2x² - 9x + 2 + 1 = 0
2x² - 9x + 3 = 0
a = 2 b = -9 c = 3Soo :
D = b² - 4ac
D = (-9)² - 4(2)(3)
D = 81 - 4(6)
D = 81 - 24
D = 57

Answer: x = 90°, therefore 3x = 270°
Step-by-step explanation:
The null space on the left of the shape is a 45-45-90 triangle. Since the internal angle is therefore 90°, 3x = 360°-9°, solving for x this yields x= 90°.
Find f(-2) and g(5)
f(x)=-2x³-5 g(x)=-4x+2
Answer:
f( -2) = 11
g(5) = - 18
Step-by-step explanation:
#1. Solving for f(-2)We're given a function "f" such that when it accepts a variable x, it's output, f(x), is:
[tex] \boxed{ \mathsf{f(x) = - 2 {x}^{3} - 5}}[/tex]
The value of f(x) depends upon what value of x is being inserted.
If x = -2
All the places taken by x will be given to -2
[tex] \implies \mathsf{f( - 2) = - 2( { - 2}^{3} )- 5 }[/tex]
(-2)³ is the cube of (-2) with -8 as it's result
[tex] \implies \mathsf{f( - 2) = - 2( { - 8}^{} )- 5 }[/tex]
when there's no operating sign between two numbers from different origin, they're multiplied
[tex] \implies \mathsf{f( - 2) = 16 - 5 }[/tex]
[tex] \implies \mathsf{f( - 2) = 11 }[/tex]
That gives us the value of f(-2) :
11
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
#2. Solving for g(5):Here's another function, "g", taking x as input and giving us an output g(x), such that:
[tex] \boxed{ \mathsf{g(x) = - 4x + 2}}[/tex]
If x = 5
All the positions taken by x will be given to 5:
[tex] \implies \mathsf{g(5) = - 4(5) + 2}[/tex]
no sign between two numbers from different origin results in their product.
[tex] \implies \mathsf{g(5) = - 20+ 2}[/tex]
[tex] \implies \mathsf{g(5) = - 18}[/tex]
Thus, the value of g(5) is:
-18

Awnsehthrhdhdhehdhsbgsgshdhdhdgsh
Answer:
B
Step-by-step explanation:
Let's eliminate the incorrect answers. C and D are incorrect, since anything to the power of 0 is equal to 1. A is incorrect, because -1 * -1 = 1 since the negatives cancel out. B is correct, because -1*-1*-1*-1*-1 has an odd number of negatives, and thus you are left with -1 instead of 1. Therefore, the answer is B.

-5 ( x - 1 ) - x + 1 = -18
Answer:
x=4
Step-by-step explanation:
-5x+5-x+1=-18
combine like terms
-6x+6=-18
subtract 6 from both sides
-6x=-24
divide both sides by -6
x=4
Answer:
x=-4
Step-by-step explanation:
-5 ( x - 1 ) - x + 1 = -18
-5x+5-x+1=-18
6x+6=-18 <- -6 from both sides
6x=-24 <- divide 6 by both sides
x=-4

A box contains 6 black pens, 4 blue pens, and 7 red pens. Without looking, Clarissa randomly picks a red pen out of the box. If she chooses another pen out of the box without replacing the first one, what is the probability that she will pick a red pen both times? Write your answer as a percent rounded to the nearest whole.
Answer:
37.5%
Step-by-step explanation:
without replacing 7 becomes 6 so
6+6+4=16
and you have 6 red pens in the box so. 6/16 as a decimal is 37.5%

If two angles of one triangle equal in measure to two angles of another triangle then the third angles of the triangle
Answer:
Are also equal
Step-by-step explanation:
Say triangle A has the angles 30 and 60. triangle b also has those angles. Total angle of any triangle is 180 so 180-60-30 = 90 for triangle A and it is also the same for triangle b. Thus 90 = 90 angles are the same.

Okay, So we're given that the amount of time it takes for class one to end is normally distributed. The amount of time it takes for the class to to start is normally distributed. And the amount of time it takes to get from class one to class two is also normally distributed. And they have these normal distributions, I have been down here. X one is the time that it takes to get to The time it takes for the first class to end. X two is the time it takes for the second class to begin. An X three is the time It takes to get from Class 1 to class too. So what I'm gonna do is I'm gonna let t equal X one plus X three and X one plus X three is the time it takes for the first class to end, added to the time it takes to get from class one to class too. So this will be equal to This will be equal to do one of these lines is equal to a normal distribution where we add the main values and we add the variances and this is allowed because all three of these are normally distributed and they're all independent of each other. We can do that when they're independent of each other. So if we add 902-6 minutes we get 908 and if we add one squared to 1.5 squared 1.5 squared is 2 to 5. So this is 3 to 5. And now that we have this normal distribution of the time it takes to get to class two added to the time it takes for the first class to end. We can now set this up With this 3rd distribution. So what we're trying to find is we want this time this normal distribution to be less than at the time it takes for the class to to start. So this normal distribution, so we want t To be less than X two. And so what we're gonna do now is I'm gonna rewrite this by just minus ng ti from both sides. So you get zero Is less than X two -T. And now we can set this up as another normal distribution by minus ng the two means and then we still add the variances. So this would be normal Where we have 908. We're sorry, we have 9 10 minus 98 just to two minutes and we have 3.25 Added to one squared up here. So that is 4.25 as our variants. And now what we can do is just set up a Z score. So right now we want to find the probability that X two minus T is greater than zero, but I'm going to change this. So we've found the probability of Z is greater than 0-. Are you divided by our variance? I'm sorry, our standard deviation and this will let us use then the standard normal distribution table to find our probability. So if we let zero minus you, if we set up this, so we actually find zero minus, you will use to so we know zero minus you is negative two and the standard deviation, It's just the square root of our variance, which is 4-5. So we're trying to find the probability that Z is greater than -2 over the square to 4.25. And we can do this by setting this up a different way, we can say that this is equal to one minus the probability that Z is actually less than or equal to -2 over the square to 4.25. And this will make it. So we can actually look at our distribution table And find the value that we need to, which is the value at -2 divided by the square to 4.25. So if we simplify this further, We'll see that -2 divided by the square Of 4-5, goes to about -97. And now if we go and look at our Normal distribution table, we'll see that the value at negative .97 Is just about .16 60 And so now all we have to do is take one and subtract this value of .1660. And we'll get a resulting value of .834, which is then our probability.

solve 6y + 8y =17 + 81
Answer:
y= 7
Step-by-step explanation:
6y + 8y =17 + 81
Combine like terms
14y = 98
Divide by 14
14y/14 = 98/14
y =7
Answer:
y=7
Step-by-step explanation:
Add 17 and 81 which is 98
then add 6y and 8y because they are also like terms which is 14y
now you have 14y = 98
then divide by 14 on both sides to get y by itself
then you will need to do 98/14 which is 7
answer is y=7
To convert miles per hour to feet per second, which conversion factor would not be used?
1 hr60 min
1 hr60 min
1 min60 sec
1 min60 sec
5280 ft1 mi
5280 ft1 mi
1 mi
5280 ft
I'm doing this right now too :)
You start by writing the original numbers given into a proportion, which would be
miles
_____
hours
Then you have to convert the top unit, miles, into feet. You have to use the rate 1mile:5280 feet. You write that as a proportion too.
miles 1
_____ = ___
hours 5280
Next, you have to add a conversion rate for changing the hours into seconds. You'd use the rate 1 hour: 60 seconds.
miles 1 60
_____ = ___ = ____
hour 5280 1
Then you'd cross multiply to solve.

y= 10x +2 and -5x + 4y=-27
Answer:
x = -1
y = -8
Step-by-step explanation:
if y=10x+2 then we can substitute that expression in for 'y' in the second equation to solve for 'x':
-5x + 4(10x+2) = -27
-5x + 40x + 8 = -27
35x + 8 = -27
35x = -35
x = -1
now solve for 'y':
y = 10(-1) + 2
y = -10 + 2
y = -8
