write an equation represented by the graph shown !
Answer:
y = |x+1.5|
Step-by-step explanation:
Start with the graph of y = |x|. To shift it left by 1.5 units, replace x with x+1.5.
General rules for shifting graphs:
Shift y = f(x) up by a units: y = f(x) + aShift y = f(x) down by a units: y = f(x) - aShift y = f(x) left by a units: y = f(x + a)Shift y = f(x) right by a units: y = f(x - a)Answer:
y=abs(x+1.5)

What should be done to these equations in order to solve a system of equations by elimination?
I- 3x + 2y = 16
12x + 5y = 21
Choose one correct answer:
Multiply the first equation by 2 and the second equation by 3.
Multiply the first equation by 3.
O Nothing needs to be done, since they both equal have 2's and 3's for coefficients.
O Multiply the first equation by
3 and the second equations by 2
Answer:
B is the correct answer
Step-by-step explanation:
Since it gets rid of the y so you could find the x and then work around to find the Y.
Answer:
Multiply the first equation by 3.
Step-by-step explanation:
What is wrong with this solution? -6t + 16 = -8 Step One: -6t + 16 = -8 - 16 Step Two: -6 • -6t = -24 • -6 Solution: t = 144
Answer:
t = 4
Step-by-step explanation:
In step two, instead of multiplying by -6 on both sides, you need to divide by -6 to isolate t.
-6t = -24
÷-6 ÷-6
t = 4
When you multiply by -6 on both sides, the equation would be 36t = 144, which is not what we want. The opposite of multiplication is division, and in order to get the answer, you divide by the number multiplied.

Four equivalent forms of a quadratic function are given. Which form displays the zeros of function h?
Answer:
[tex]h(x) = -4(x - 2)(x + 2)[/tex]
Step-by-step explanation:
Given
[tex]h(x) = -4(x - 2)(x + 2)[/tex]
[tex]h(x) = -2(2x^2 - 8)[/tex]
[tex]h(x) = -4(x^2 - 4)[/tex]
[tex]h(x) = -4x^2 + 16[/tex]
Required
Which shows the zeros of h(x)
To determine the zeros of a function, the function must be written as:
[tex]h(x) = n(x \± a)(x \± b)[/tex]
Where
[tex]n \ne 0[/tex]
[tex]\± a,\± b[/tex] are the zeros
Of options (a) to (d), only (a) is written in the form:
[tex]h(x) = n(x \± a)(x \± b)[/tex]
i.e.
[tex]h(x) = -4(x - 2)(x + 2)[/tex]
Other options do not show the zeros

Find the interquartile range.
A. 2 - 1 = 1
B. 11 - 1 = 10
C. 10 - 2 = 8
D. 11 - 5 = 6
Answer:
C. 10 - 2 = 8
Step-by-step explanation:
[tex] = (Q _{3} - Q _{1}) \\ = ( \frac{3}{4} \times 7) - ( \frac{1}{4} \times 7) \\ = (6 {}^{th} - {2}^{nd} ) \\ = (10 - 2) \\ = 6[/tex]

Each table in a library can seat up to 5 people. There are enough tables for 75 people. How many tables are there in the library?
Answer:
15 tables
Step-by-step explanation:
75/5 = 15
Answer:
There are 15 tables in the library.
Step-by-step explanation:
You know this because you know the library holds 75 people and you know how many people can sit at a table so to find the answer you divide 75 by 5 and you get 15. To check this you can multiply 15 by 5 and you will get 75.

A container must contain at least 40 pounds of potatoes and at least 20 pounds of onions. The combined amounts of potatoes and onions
must be at least 80 pounds but must not exceed 160 pounds.
Let z represent the number of pounds of potatoes and y represent the number of pounds of onions.
Which system of inequalities can be used to find the values of r and y?
(x240
OA
y2 20
x + y s 80
(x + y 2 160
x 540
y s 20
x + y s 80
(x + y 2 160
x 240
y2 20
x + y 2 80
(x + y s 160
OD
x 540
y s 20
x + y 2 80
x + y s 160
Answer:
The system of inequalities can be used to find the values of x and y is
z ≥ 40
y ≥ 40
x+y ≥ 80
x+y ≤ 160
Step-by-step explanation:
Let z represent the number of pounds of potatoes and y represent the number of pounds of onions.
In mathematics at least means equal or greater than ,
So applying this property we get
z ≥ 40 → at least 40 pounds of potatoes
y ≥ 40 → at least 20 pounds of onions
x+y ≥ 80 → combined must be at least 80 pounds
x+y ≤ 160 → but must not exceed 160 pounds.
So the correct choice is B

THE FASTEST AND MOST ACCURATE GETS THE BRAINLIEST NO LINKS PLS. Hannah and Harold are making cookies for a bake sale, and they need to make a lot of them. They need to make 70 baggies of cookies that each have 4 cookies in them. The recipe they are using says that one batch will make 2 dozen cookies.
Answer:
They need to make at least 12 batches.
Step-by-step explanation:
First, we need to find how many cookies in total, so we multiply 70 by 4.
70*4 = 280.
Secondly, 1 batch makes 2 dozen cookies, or technically 24 cookies. So we need to find how many batched with 280 divided by 24. This results in 11.6 repeating. But if you round it up, you get 12.
Time to check:
12 * 24 = 288. So it's the amount of cookies needed with 8 remaining.
Hope this helps.
