Write the absolute value equation given the transformations
shifts right 5 units
shifts up 2 units
is reflected
is stretched by 0.5
Answer:
y = - 0.5 | x - 5 | + 2
Step-by-step explanation:
g(x) = |x|
[tex]1^{st}[/tex] step - shifts right 5 units: g(x + 5) = | x - 5 |
[tex]2^{nd}[/tex] step - shifts up 2 units: g(x + 5) + 2 = | x - 5 | + 2
[tex]3^{rd}[/tex] step - reflected: - g(x + 5) + 2 = - | x - 5 | + 2
[tex]4^{th}[/tex] step - stretched by 0.5: y = - 0.5 | x - 5 | + 2
y = - 0.5 | x - 5 | + 2

General Formulas and Concepts:
Pre-Alg
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
-17 = -3/2b
Step 2: Solve for b
Rewrite: -3/2b = -17Divide both sides by -3/2: b = 34/3Step 3: Check
Plug in b to verify it's a solution.
Substitute: -17 = -3/2(34/3)Multiply: -17 = -17What is the value of k?

Answer:
6z - 6
Step-by-step explanation:
When you expand you are removing brackets. This means you multiply the outer number by the ones inside thus:
2(3z-3)
2 times 3z is 6z .
2 times 3 is 6.
So the answer is 6z - 6.

Painter A charges $70 to start a job and $80 per hour he/she is there. Painter B charges $100 per hour. Write an inequality that would determine how many hours would the job take for Painter A to be less expensive and solve.
Let the number of hours be x.
70 + 80x < 100x
20x > 70
x > 3.5

You have $18 to buy peppers. Peppers cost $1.50 each. Write and solve an inequality that represents the numbers of peppers you can buy.
the inequality would be 18>1.5x
this basically means $18 is greater than or equal to 1.5x, where x is the number of peppers you buy at $1.50 for each pepper. So you can buy any amount of peppers from 0 to 12. If you want to make the inequality better it would be 18>1.5x>0 because you can't buy less than 0 peppers

is it exponential growth or decay ?
what’s the initial value ?
what is the rate of growth or rate of decay ?
Answer:
You should probably double check the problem. The equation you have is just 100-1.25
Rob can lift less than 135 pounds at the weight room. There is already 48 pounds of weights on the bar. Write an inequality that shows the additional weight that Rob can add, w, without being over his maximum.
Answer:
[tex]x + 46 < 135[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Weight = 48lb[/tex]
He can lift less than 135 implies that, his maximum is:
[tex]Total < 135[/tex]
Required
Determine the additional weight
Let the additional weight be x
Such that
[tex]Total = x + Initial\ Weight[/tex]
[tex]Total = x + 46[/tex]
Substitute x + 46 for Total in [tex]Total < 135[/tex]
[tex]x + 46 < 135[/tex]
Hence, the inequality that describes the scenario is: [tex]x + 46 < 135[/tex]

help me please and thank you
factorise the following:
[tex]{3x}^{2} + 5x - 12[/tex]
Answer:
(x + 3)(3x - 4)
Step-by-step explanation:
Given
3x² + 5x - 12
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 12 = - 36 and sum = + 5
The factors are + 9 and - 4
Use these factors to split the x- term
3x² + 9x - 4x - 12 ( factor first/second and third/fourth terms )
= 3x(x + 3) - 4(x + 3) ← factor out (x + 3) from each term
= (x + 3)(3x - 4)
Thus
3x² + 5x - 12 = (x + 3)(3x - 4) ← in factored form
guys please help/ no answers from google!
it's for tomorrow
Answer:
Length --> x
Width --> y
Perimeter of a rectangle --> 2x + 2y
The length is always 4 cm more than double the width
x - 4 = 2y
y = (x-4)/2
x = 2y + 4
a. The polynomial equation to give the perimeter --> 2(2y+4) + 2((x-4)/2)
b. x - 4 = 2·6 --> x - 4 = 12 --> x = 16
Perimeter --> 2·16 + 2·6 = 44 cm
Jamie buys a ring that is priced at $900. What is the sales price of the ring, if Jamie uses the coupon below?
A.$885
B.$15
C.$765
D.$135
Answer:
D= $135
Step-by-step explanation:
We have to use proportions in order to figure this out. We know that 15% is equal to 15/100.
work:
15/100=x/900.
We cross multiply so its 13,500/100. This is not the answer so we divide which equals to $135

Answer two questions about Equations AAA and BBB: \begin{aligned} A.&&\dfrac x4+1&=-3 \\\\ B.&&x+4&=-12 \end{aligned} A. B. 4 x +1 x+4 =−3 =−12 1) How can we get Equation BBB from Equation AAA? Choose 1 answer: Choose 1 answer: (Choice A) A Rewrite one side (or both) using the distributive property (Choice B) B Rewrite one side (or both) by combining like terms (Choice C) C Multiply/divide only one side by a non-zero constant (Choice D) D Multiply/divide both sides by the same non-zero constant 2) Based on the previous answer, are the equations equivalent? In other words, do they have the same solution? Choose 1 answer: Choose 1 answer: (Choice A) A Yes (Choice B) B No
The given equations are as follows
[tex]\begin{aligned} A.&&\dfrac x4+1&=-3 \\\\ B.&&x+4&=-12 \end{aligned}[/tex]
(1) First, multiply both sides of equation A by 4, we have
[tex]4\times\left(\frac{x}{4} +1\right)=4\times(-3)[/tex]
Then, rewrite the left-hand side of the above equation by using the distributive property, we have
[tex]4\times\frac{x}{4}+4\times1=4(-3)[/tex]
[tex]\Rightarrow x+4=-12[/tex]
This is the required equation B.
In this way, first use choice D: Multiply both sides by the same non-zero constant, i.e 4.
Then, apply choice A to solve the equation, i.e using the distributive property to solve the left-hand side of the equation.
(2) In the previous answer, equation B has been derived from equation A, hence, both the equations are equivalent.
As both the equations are the same, so both will have the same solution.
Yes, they have the same solution.
