Answer:
True
Step-by-step explanation:
When you plug in -2 for the x-values, it should be like this -3(-2)^3 + 2((-2)+2). When using the method of PEMDAS, you want to do the parentheses/exponents first since it is in order. -2 to the power of 3 is -8 for this case. Distribute 2 in -2 and 2 to get -4 + 4. Obviously. they will cancel in which you are left with -3(-8). Two negatives multiplied together equals a positive, so your final answer should be 24, in this case it is true.

x-7y= -49 (ANSWER?)
Answer:
[tex]y = \frac{1}{7} x + 7[/tex]
Step-by-step explanation:
x-7y = -49
i) move x to the right-hand side and change its sign
-7y = -49-x
ii) change the signs on both sides of the equation
7y = 49+x
iii) divide both sides of the equation by 7
[tex] \frac{7y}{7} = \frac{49}{7} + \frac{x}{7} [/tex]
[tex]y = 7 + \frac{1}{7} x[/tex]
iv) use the commutative property to reorder the terms
* commutative property: a+b = b+a
[tex]y = \frac{1}{7} x + 7[/tex]

1 1/4 + 2 2/4 + 3 3/4 + 1/4 + 2 1/4 = ?
The answer is 10.
Step-by-step explanation:
We need to solve 1 1/4 + 2 2/4 + 3 3/4 + 1/4 + 2 1/4.
Every fraction has a denominator as 4. So, the denominator of the whole fraction is 4.
[tex]\dfrac{5}{4}+\dfrac{10}{4}+\dfrac{15}{4}+\dfrac{1}{4}+\dfrac{9}{4}\\\\=\dfrac{5+10+15+1+9}{4}\\\\=\dfrac{40}{4}\\\\=10[/tex]
So, the value of the given expression is 10.

3 * 2 * 2 possible combinations
For example:
S = 3 sizes
F = 2 flavours
T = 2 toppings
Then there are 3 * 2 * 2 = 12 possible combinations
Write each fraction as a decimal Use abar as needed.

2x+5y =-20, 2x-3y=28
Answer:
x=5 and y=-6
Step-by-step explanation:
2(5) + 5(-6) = -20 (so true)
and
2(5) - 3(-6) = 28 (true)
Answer:
2x=-20-5y
divide both sides by 2
x=-20-5y/2
2x-3y=28
-3y=28-2x
divide both sides by -3
y=28-2x/-3

1. It is the capacity to direct and discipline one's
activities and the behavior using reason that is
cautious and, as much as possible, keeps
from any risks.
Answer:
The answer is "Prudence".
Step-by-step explanation:
It is the capacity, through the use of justification, to regulate or control yourself. Although pragmatism does not perform any actions and seems to be concerned primarily with information, it would have to control certain values. It is also the desire, utilizing purpose, to direct the control from one's activities and behavior.
If [tex]\sf a = log_92[/tex] and [tex]\sf b = log_54[/tex], find [tex]\sf log_615[/tex] in terms of a and b.
Answer:
(4a + b)/(2ab + b)Step-by-step explanation:
Givena = log9 2b = log5 4To findlog6 15 in terms of a and bSolutionRewrite the given
log9 2 = a ⇒ log2/log9 = a ⇒ 1/2*log2/log3 = a ⇒ log3 = 1/2*log2/alog5 4 = b ⇒ log4/log5 = b ⇒ log5 = 2*log2/bRewriting the log6 15:
log6 15 = log15/log6= (log 5 + log3)/(log2 + log3)Substitute as follows:
(log 5 + log3)/(log2 + log3) =(2*log2/b + 1/2*log2/a)/(log2 + 1/2*log2/a) =(2/b + 1/(2a))/(1 + 1/(2a)) =(4a + b)/2ab ÷ (2a + 1)/2a =(4a + b)/(2ab + b)Which method listed below would NOT be used to prove that two triangles are congruent?.

Equality PropertiesStep-by-step explanation:
Step 1: Define
7x - 9 < 12
Step 2: Solve for x
Add 9 to both sides: 7x < 21Divide 7 on both sides: x < 3Here we see that any value x smaller than 3 would work as a solution to the inequality.
Answer:
x < 3

Estimate the number of words in your textbook, without using a calculator.(The book has about 500 pages, with an average of 38 lines on a page, 12 words on a line.)
Answer:
[tex]500\ Pages = 228000[/tex]
Step-by-step explanation:
Given
[tex]Pages = 500[/tex]
[tex]Lines = 38[/tex]
[tex]Words = 12[/tex]
Required
Determine the number of words in the book
First, we need to calculate the number of words in a page.
[tex]1\ Page = Words * Lines[/tex]
[tex]!\ Page = 12 * 38[/tex]
[tex]1\ Page = 456[/tex]
Next, we calculate number of words in 500 pages
Multiply both sides by 500
[tex]500 * 1\ Page = 456 * 500[/tex]
[tex]500\ Pages = 228000[/tex]
Hence, there are 228000 words in the book

Rachel and David were shopping for holiday gifts when they noticed a Thanksgiving sweater on the discount rack. Rachel really wanted the sweater, even though she wouldn’t be wearing it until Thanksgiving of 2021! Part A: If the original price of the sweater was $24.00, and the sweater is on sale for 60% off, what is the sale price?
Answer:
[tex]Sales\ Price = \$9.60[/tex]
Step-by-step explanation:
Given
[tex]Price = \$24.00[/tex]
[tex]Discount = 60\%[/tex]
Required
Determine the sales price
First, we calculate the discount price
[tex]Discount\ Price = Price * Discount[/tex]
[tex]Discount\ Price = \$24.00 * 60\%[/tex]
[tex]Discount\ Price = \$14.4[/tex]
The sales price is then calculated by subtracting the discount price from the original price of the item
[tex]Sales\ Price = Price - Discount\ Price[/tex]
[tex]Sales\ Price = \$24.00 - \$14.40[/tex]
[tex]Sales\ Price = \$9.60[/tex]
