you plug the number for the variable into the equation (3(2)²+6order of operations say exponents first so you do 2²=4 so you have 3(4)+6then you multiple 3•4=12 so 12+6finally you add 12+6=1823
plug in the number for the variable so 5–(-5)so a negative and a minus will make it addition (negative + negative = positive)do it is 5+5 which equals 10Related Questions

Which of the following graphs shows the solution set to t > 4 or t < -1?
Answers
Answer:
The second graph
Step-by-step explanation:
t is greater than 4 and less than -1 but doesn't include the points 4 and -1 (thus the open circles)
The second graph represents the solution set to t > 4 or t < -1.
What are open and closed interval ?In open interval we do not include the point and represented by open circle in close interval we do include the points and represented by closed interval.
According to the given question we have to determine which graph represents the solution set t > 4 or t < -1.
We know when we represent less than or greater than in the number line we represent it as an open circle.
So, t > 4 will be represented by an open circle on the number line starting at 4 but not including which goes to positive infinity and t < -1 will be represented by an open circle at -1 not including which goes to negative infinity.

Answer:
A
Step-by-step explanation:
Tran earns $16 per hour and is paid a flat fee of $46 each week. At
the end of the week her total salary can be represented by the
equation y=16x + 46, where x is the number of hours, and y is the
total weekly salary. Write this relationship in functional notation, as a
function S(h), where S(h) represents the salary for h number of hours.
Answers
Answer:
[tex]S(h)=16h+46[/tex]
Step-by-step explanation:
We just need to substitute the variables here! You already have the equations so instead of [tex]x[/tex] for hours, we use [tex]h.[/tex] And since it's a function the result is not [tex]y[/tex] but rather [tex]S(h)[/tex].
So we get the answer of: [tex]S(h)=16h+46[/tex]
The height of a building is 72 m. Find the angle of elevation from a point on ground level that is 55 m away from the base of the building
Answers
Answer:
52.6 degrees
Step-by-step explanation:
tan^-1(72/55)
Angle of elevation is equals to 52°7'(approximately).
What is angle of elevation?
" Angle of elevation is the angle between the horizontal plane and line of sight from the point of observation."
Formula used
In a right angled triangle,
tanθ = ( opposite side) / adjacent side)
According to the question,
As shown in diagram
Height of the building (AB) = 72m
Distance between base of the building and point of observation
(BC)= 55m
Angle of elevation = θ
Substitute the value in the formula we have,
tanθ = AB / BC
= 72 / 55
⇒ θ = tan⁻¹ (72 /55)
= tan ⁻¹(1.3091)
= 52° 7' (approximately)
Hence, angle of elevation is equals to 52°7'(approximately).

Find the intercepts of the graph given the following equation 4x – 3y = 12
Answers
Answer:
y-intercept: -4 or (0, -4)
x-intercept: 3 or (3, 0)
Step-by-step explanation:
4x - 3y = 12
we can convert this to slope-intercept form (y = mx+b) given that m is the slope and b is the y-intercept
4x - 3y = 12
-3y = -4x + 12
y = 4/3x - 4
So the intercept is -4 or (0, -4).
For the x-intercept, we can make the y value 0 to solve for x.
4x - 3y = 12
4x - 3(0) = 12
4x = 12
x = 3
So the x-intercept is 3 or (3, 0).

The expression 4x − 2(5x − 1) is equivalent to the expression 2 + 6x.
True
or
False
Answers
Answer:
False
Step-by-step explanation:
Let us evaluate the problem using the proper order of operation:
4x − 2(5x − 1)
To solve this problem, we use the order of operation called PEMDAS;
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
Now, since operations inside the parentheses are of the utmost priority, let us solve this;
4x − 2(5x − 1)
= 4x - 10x +2
= -6x + 2 or 2 - 6x
We see that the solution give is false.

Answers
Answer:
5. 34% 6. $190.73
Step-by-step explanation:
trust man just trust
Answer:
5) 52
6) $190.73
Step-by-step explanation:
5)
Let the unknown number be x.
40 is 77% of x
40 = 0.77x
Divide both sides by 0.77
x = 52
Answer: the number is 52.
6)
We first calculate the amount of tax which is 6.875% of $178.46.
6.875% of $178.46 =
= 0.06875 * $178.46
= $12.27
The amount of tax is $12.27.
Now we add the amount of tax to the price before tax.
$178.46 + $12.27 = $190.73
Ok last one my sis needs help on lol again I’m doing my homework and cAnT HeLp rn pls just help lol
Answers
Answer:
Part A: 15.55
Part B: 0.45
Step-by-step explanation:
Part A:
The giraffe is already 14.29 so when you add the length of its tongue (equation 14.29 + 1.26) then that would equal 15.55
Part B:
The giraffe is trying to eat some leaves that are 16 feet above the ground so you would subtract 16 - 15.55 to see how much farther it needs to reach, so the answer is 0.45.
(This is what I got, I apologize if I get this wrong. If I messed up on something, someone please correct me, thank you and have a nice day!)
Answer:
Part A: It can reach 15.55 feet.
Part B: Need to reach 0.45 feet farther to get to the leaves of a 16 feet tree.
Step-by-step explanation:
giraffe + tongue = reach
14.29 + 1.26 = 15.55
tree height - giraffe reach = extra distance
16 - 15.55 = 0.45 feet
