simplify (3 * -8) plus (2x+5)-(4x-8)
The simplified value of the given expression is -11 - 2x.
BODMAS stands for Brackets of Division, Multiplication, Addition and Subtraction.
Here, we are given an expression as follows-
(3 * -8) + (2x+5) - (4x-8)
According to the rules of BODMAS, brackets must be solved first. Hence, we simplify the terms in brackets first as given below-
(-24) + (2x + 5) - (4x - 8)
Opening up the brackets we get-
-24 + 2x + 5 - 4x + 8
= -24 + 5 + 8 + 2x - 4x
= -24 + 13 -2x
= -11 - 2x
Thus, the simplified value of the given expression is -11 - 2x.

whats the simplest form of b⁴ b²?
Answer:
Step-by-step explanation:
Simplify ((b^4)^4) / ((b^2)^3).First lets simplify the numerator. ((b^4)^4). The notation is b to the fourth power, to the fourth power, which is multiplying sixteen b’s. That explains why we multiple the exponents, to get b^(16) for the numerator.Similarly we simplify the denominator by multiplying the exponents for ((b^2)^3) = b^6.Putting the simplified numerator and denominator together is (b^(16))/(b^6).The six b’s in the denominator cancel six b’s in the numerator for (b^(16))/(b^6) = b^(10). Final answer b^(10).Note, another way to view (b^(16))/(b^6) = (b^(16)) * (b^(-6)) then add the exponents to have the same answer (b^(10))

How many degrees must figure A be rotated counterclockwise around the origin in order to line up with Figure B?
Answer:
270
Step-by-step explanation:
One turn would put you in quadrant 2 and would be 90. A second turn would put you in quadrant 3 and that would be 180. A third turn would put you in quadrant 4 and that would be 270. I know that it is hard to see what I mean by a turn. It would be if you had a piece of tracing paper with the figure drawn on it and you turn the paper at the origin so that the lines at the corners would like up, each turn would be 90 more degrees.

Teresa received a gift card of $70 for a different pizza restaurant .the restaurant charges $10 per pizza .let X be the number of pizzas purchase. for each card write an expression for the amount of money left on the card after purchasing X pizzas.
a)Amount of money left on Pablo's card in dollars = $100 - $15x
= $(90 - 15x)
b) Amount of money left on Teresa's card in dollars= $70 - $10x
= $(70 - 10x)
c) Write an equation to show that the two cards have the same amount of money left on them [don't know how to do this part.
$100 - 15x = $70 - 10x
Let x be the number of pizzas purchased. For each card, write an expression for the amount of money left on the card after purchasing x pizzas.
For Pablo
Keith received a gift card of $100 for a pizza restaurant. The restaurant charges $15 per pizza.
x numbers of pizza costs = $15x
Hence, the amount of money left on Pablo's card after purchasing x pizzas = $100 - $15x
For Teresa,
Mary received a gift card of $70 for a different pizza restaurant. The restaurant charges $10 per pizza.
Hence, x number of pizzas cost =$10 × x
= $10x
Therefore, the amount of money left on Mary's card after she buys x pizzas =
$70 - $10x
Amount of money left on Pablo's card in dollars = __________
Amount of money left on Teresa's card in dollars=____________
Write an equation to show that the two cards have the same amount of money left on them.
To find the equation that shows that the two cards have the same amount of money =
Equation 1 = Equation 2
$100 - 15x = $70 - 10x
Collect like terms
-15x + 10x = $70 - $100
-5x = -30
x = 30/5
x = 6
Hence, anytime Pablo and Teresa buys ,6 pizzas their gift card will have the same amount of money left on them.

Tristan used his graduation money of $2000 to set up a savings account. He wants to determine which investment would make the most money.
Find the amount of money each investment would yield after 5 years.
How much would Tristan earn with Account A: 5.7% interest compounded monthly
The amount that Tristan would earn in 5 years is $657.30.
How much would Tristan earn?When an amount is compounded monthly, it means that both the amount invested and the interest that has already accrued increases in value every month or 12 times in a year.
The first step is to determine the future value of the investment.
The formula for calculating future value:
FV = P (1 + r)^nm
Where:
FV = Future value P = Present value R = interest rate : 5.7% / 12 = 0.475%m = number of compounding = 12N = number of years$2000 x (1.00475)^(12 x 5)
$2000 x (1.00475)^60
= $2,657.30
Amount he would earn = $2,657.30 - $2,000 = $657.30

Which of the following must be a factor of the function
Answer:
(A) (x -2)
Step-by-step explanation:
You want to know a factor of the function whose values given in the table include (x, y) = (2, 0).
Polynomial zerosA polynomial function y = p(x) will have a factor of (x-a) if and only if p(a) = 0.
The table shows y=0 for x=2, so this polynomial function will have a factor of (x -2).
__
Additional comment
The function shown in the table is ...
y = (x -2)²
so it actually has two factors that are (x -2).
You can tell this is a polynomial function of degree 2 because the 2nd differences are constant.
First differences between successive y-values: -7, -5, -3, -1, 1, 3
Second differences between successive first differences: 2, 2, 2, 2, 2.

A ball was thrown off a bridge. The table relates to the height of the ball above the ground in feet to the time in seconds after it was thrown. Use the data to enter a quadratic model in vertex form and convert it to standard form. Use the model to find the height of the ball at 1.5 seconds.
The peak height reached at 144 feet, and the graph passing through points (0, 120), (1, 144), (2, 120), gives;
1. The vertex form of a quadratic equation is f(x) = a•(x - h)² + k
Where;
a = The leading coefficient
(h, k) = The coordinates of the vertex.
Let t represent the time of travel of the ball and let h represent the height.
From the given table, we have;
f(t) = a•(t - h)² + k
f(0) = 120 = a•(0 - h)² + k = a•h² + k
120 = a•h² + k
f(1) = 144 = a•(1 - h)² + k = a•(h² - 2•h + 1) + k
f(1) = a•(h² - 2•h + 1) + k
f(1) - f(0) = 144 - 120 = 24 = -((2•h - 1)•a
24 = -((2•h - 1)•a
f(2) = 120 = a•(2 - h)² + k
f(2) - f(1) = -24 = -((2•h - 3)•a
(f(1) - f(0)) - (f(2) - f(1)) = 48 = -2•a
Therefore;
a = -24
24 = -((2•h - 1)•a
24 = -((2•h - 1)×(-24)
-1 = -((2•h - 1)
2•h - 1 = 1
h = 2/2 = 1
h = 1
120 = a•(2 - h)² + k
120 = (-24)•(2 - 1)² + k
k = 120 + 24 = 144
k = 144Which gives;
The vertex form is y = -24•(x-1)² + 144
From the vertex form, we have;
y = -24•(x-1)² + 144 = -24•(x²-2•t+1) + 144
y = -24•(x²-2•tlx+1)+ 144 = -24•x²+48•x - 24 + 144
y = -24•x²+48•x + 120
y = -24•x² + 48•x - 24 + 144 = -24•x²+ 48•x + 120
y = -24•x² + 48•x + 120
The height of the ball after 1.5 seconds is
y = -24×1.5² + 48×1.5 + 120 = 138
The height of the ball at t = 1.5 seconds is 138 feetLearn more about quadratic equations here:

Use the fact that 1 kilometer = 0.62 miles to convert 3,070 meters to miles.

Step-by-step explanation:
The conversion rate for meters to kilometers is 1 meter for 0.001 kilometers. Using this rate you can do, [tex]3070m*\frac{0.001km}{1m}[/tex]. The m units cancel and you're left with 3.07km. Since we are given the conversion rate of 1 kilometer = 0.62 miles, we can do, [tex]3.07km*\frac{0.62mi}{1km}[/tex]. again the km units cancel and you're left with 1.9034 mi.

Oscar is building a fence and purchases three boards that each measure
2.91 meters long. How many meters of fence board did Oscar purchase?
Oscar bought 8.73 meters of fence board to build the fence.
The metric system and the International Systems of Units both use the metre (m), also spelt as meter, as the basic unit of length (SI). In the British Imperial and American Customary systems, it is equivalent to roughly 39.37 inches.
A fence is a building used to enclose a space, usually outdoors. It is often made of posts joined by boards, wire, rails, or nets.
Oscar purchases three boards that measure 2.91 meters long each to build a fence.
Let say the length of one board be x = 2.91 meters.
Then the total length of fence board Oscar purchases is:
= 3x = 3 × 2.91 meters = 8.73 meters
Hence Oscar purchased 8.73 meters of fence board.
