According to the synthetic division below, which of the following statements
are true?
Check all that apply
=================================================
Explanation:
The number in the upper left corner of the synthetic division table is the test root we're trying out. If it leads to a remainder of 0 (bottom right corner), then we have a winner. In this case, we have a root. Choice A is one of the answers.
Since 4 is a root, this leads to x-4 being a factor. Think of x = 4 becoming x-4 = 0 when we subtract 4 from both sides. Choice C is another answer.
The remaining stuff in the bottom row forms the quotient polynomial. The coefficients 3 and -1 lead to 3x+(-1) which simplifies to 3x-1.
So this means dividing 3x^2-13x+4 over x-4 yields the quotient 3x-1 with a remainder of 0. Therefore, choice E is the correct equation compared to choice D which is close but not quite there.
Solve for x: x − 2 > 2x + 12. (1 point) x > 14 x < 14 x > −14 x < −14
Answer:
Step-by-step explanation:
x<-14
Answer:
x < -14 is correct.
Step-by-step explanation:
Here is the work:
x - 2 > 2x + 12
I will start by getting rid of the 2x , so subtract 2x from both sides.
-x -2 > 12
Add 2 to both sides.
-x > 14.
Multiply by negative 1 on both sides because -1 times -1 is 1, so you get 1x (x).
When multiplying by a negative, you switch the sign around.
x < -14.
What is (x+3)(x-3) in standard form ?
Answer:
x² - 9
Step-by-step explanation:
(x + 3)(x - 3)
= x(x - 3) + 3(x - 3) Distributive property
= x² - 3x + 3x - 9
= x² +( -3x + 3x) - 9 Associative
= x² + 0x - 9 Addition
= x² - 9

[2−∣∣−14−2(−35)∣∣]÷(−6)
What is the value of the expression?
Enter your answer as a simplified fraction in the box.
Answer: its - 7/40
Step-by-step explanation: i took the test
The value of the expression after simplifying the given expression [2−∣∣−14−2(−35)∣∣] ÷ (−6) is 0.141
What is Expression?An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. For example -
5x + 7 = 6
7r + π = 4
Given is the following expression -
[2 - | - 1/4 - 2 - 3/5|] ÷ (-6)
Assume that -
[A] = 2 - | - 1/4 - 2 - 3/5|
[B] = - 6
First, we will simplify [A] as follows -
2 - | - 1/4 - 2 - 3/5|
2 - | - 2.25 - 3/5|
2 - | - 2.25 - 0.6|
2 - | - 2.85|
2 - 2.85
- 0.85
We got -
[A] = - 0.85
Now, we can easily find the value of -
[A] ÷ [B] = (- 0.85)/(- 6)
[A] ÷ [B] = 0.85/6
[A] ÷ [B] = 0.141
Therefore, the value of the expression after simplifying the given expression [2−∣∣−14−2(−35)∣∣] ÷ (−6) is 0.141

Simon spent 1/4 of his wages on rent.
He spent 20% of his wages on food.
He spent 0.15 of his wages on clothes
Work out the fraction of his wages that he had left.
Answer:
2x/5 wages is remaining.Step 1: Lets say 'x' is the total wage. Then we subtract 1/4 from the total wages.
=> 4x/4 - x/4
=> 3x/4 = Remaining Wages Left.
Step 2: Subtract 20% from 3x/4.
3x/4 - x/5 = Remaining Wages Left. [20% = 20x/100 = x/5]
=> 11x/20 = Remaining Wages Left.
Step 3: Subtract 0.15x from his remaining wages left.
=> 11x/20 - 3x/20 = Remaining Wages Left. [0.15 = 15/100 = 3/20]
=> 8x/20 = Remaining Wages Left.
Step 4: Simplify
8x/20 = 2x/5 = 0.40x
=> Simon has saved 2x/5 of the wages.

Mrs. Speas has $138 in her bank account during Week #1. At the end of each week, she deposits $55 into her bank account. What is the first term?
What is the difference?
What is the iterative rule for the amount of money Mrs. Speas has after n weeks? (you are NOT required to simplify)
Answer:
24
Step-by-step explanation:
is the answer.
The first term is 138
The difference is 55
The iterative rule for the amount of money Mr Speas has after n weeks is
55/2 n² + 221/2 n
During the first week she has $138 in his bank account. At the end of each week she deposited $55 into her bank account.
The first term will be 138 .
The common difference is 55 because her bank always increase by $55 dollars every week. The sequence will be 138, 193, 248, 303, 358...…
The difference = 193 - 138 = 55.
The iterative rule for the amount of money Mr Speas has after n weeks can be represented below
n = number of weeks
a = first term = 138
d = common difference = 55
Using AP formula,
sₙ = n/2(2a + (n - 1)d)
sₙ = n/2 (2(138)+ (n - 1)55)
sₙ = n /2(276 + 55n -55)
sₙ = n /2(221 + 55n)
sₙ = 55/2 n² + 221/2 n

You earn $20 for washing 5 cars how much do you earn for washing 2 cars
Answer:
$8
Step-by-step explanation:
First we have to see how much you are paid per car. To do this we divide the money earned ($20), by the number of cars washed (5).
20÷5=4
This tells us you earn $4 per car. So, to find the amount you would earn buy washing 2 cars, you multiply the money earned per car by 2.
4·2=8
This means you would earn $8.

costs $2.454 on average per gallon for gas, how much money should the family plan to spend on gas to
drive the hybrid car for a year? Please round all work to the thousandths place when working out solutions
with final answers rounded to the nearest hundredth.
Given:
high ways :
