Answer: B) 19
Step-by-step explanation:
To solve this problem, simply plug in -4 for x:
[tex]f(x)=x^{2} +3\\f(x)=(-4)^{2} +3\\f(x)=16+3\\f(x)=19[/tex]
Hope it helps :) and let me know if you want me to elaborate/explain further
Answer:
D. -13
Step-by-step explanation:
If you substitute -4 in for x you get -4^2+3, so when you simplify you get -16+3 which equals -13.
f(x)=x^2+3
f(-4)= -4^2+3
f(-4)= -16+3
f(-4)= -13

Solve for the given variable.
3s - 17 = 19
Add 17 to both sides-
3s - 17 = 19
+17 +17
Now, divide both sides by 3-
3s/3 = 36/3
Which gives the answer of s = 12

15.38 x 10-2 in standard form
Answer:
[tex]15.38 \times {10}^{ - 2} = 0.1538[/tex]
I hope I helped you^_^
15.38x10^-2 isn't proper scientific notation.
The coefficient must be between 1 and 10.
Proper scientific notation would be
1.538 x 10^-1
Convert into standard form:
0.5138 is our answer.
And we're done!
Hope it helps you! :)

A side of the triangle below has been extended to form an exterior angle of 135º. Find
the value of x.
xo
135
115
Answer:
X = 45
Step-by-step explanation:
x + 135 = 180 {Linear pair}
x = 180 - 135 {Subtract 135 from both sides}
x = 45
Question: All of the following trigonometric functions have the same value except
Answers: Pick one.
cos180°
sin270°
tan90°
Answer:
[tex]\tan{90^{\circ}}[/tex]
Step-by-step explanation:
Because [tex]\cos{x}[/tex] and [tex]\sin{x}[/tex] are defined for all [tex]x[/tex](i.e. their domain is [tex](-\infty, \infty)[/tex]), so they can never be undefined. However, [tex]\tan{90}=\sin{90}/\cos{90}=\sin{90}/0[/tex], which is undefined, because you can't divide by [tex]0[/tex]. So, the answer is [tex]\boxed{\tan{90^{\circ}}}[/tex]
Use the graph and the translation (x,y) (x+1,y+4) to answer parts a and b below
Answer:
Use the translation formula to determine the new points.
A' → ( 5 + 4, -8 + 2) = ( 9, -6 )
B' → ( 1 + 4, -1 +2) = ( 5, -1 )
C' → ( -7 + 4, -3 + 2 ) = ( 3, -1 )
A' = (9, -6)
B' = (5, 1)
C' = (-3, -1)

At the beginning of the year, Grayson had $45 in savings and saved an additional $19 each week thereafter. Jacob started the year with $90 and saved $16 every week. Let GG represent the amount of money Grayson has saved tt weeks after the beginning of the year and let JJ represent the amount of money Jacob has saved tt weeks after the beginning of the year. Write an equation for each situation, in terms of t,t, and determine the who has more money saved after 18 weeks.
Answer:
The will have the same amount $ 387
Step-by-step explanation:
Grayson: y = 19x + 45
Jacob: y = 16x + 90
Grayson: y = 19(18) + 45
342 + 45 = $387
Jacob: y = 16(18) + 90
288 + 90 = $378
The theater sells two types of tickets: adult tickets for $14 and child tickets for $8.
Last night, the theater sold a total of 159 tickets for a total of $1794. How many adult tickets did the theater sell last night?
Answer:
87 Adult tickets were sold
Step-by-step explanation:
This type of question relates to a system of equations. These types of questions are pretty easy to spot and they are just about solved all the same way.
So what we first want to do is see that there is a total of 159 tickets sold. Now obviously that number consists of the adult and children tickets, therefore we need to add those two unknown numbers to get 159, so x will be for adults and y will be for children tickets. this will give us the equation x + y= 159.
Next, we want to associate the amount those tickets are with those variables, because you can only have so many adult tickets and children tickets with the given $1794. So what we need to do is similar, we just have those totals added to get the equation 14x + 8y = 1794.
Now we want to use the process of elimination to find the value of x (because we are solving how many adult tickets were sold). IN order to do elimination, we need to have the equation x + y= 159 cancel the y value to leave us with the x value. In order to do this, you need to multiply y by a value that cancels 8y in 14x + 8y = 1794, which is -8.
So we multiply the entire equation of x + y= 159 by -8 to get. Now we would add these equations together where you subtract by like terms so:
[tex]14x + 8y = 1794\\-8x - 8y = -1272[/tex]
This leaves us with 6x=522 now you would divide by 6 to isolate x which leaves you with 87.
