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
Choose the best graph that represents the linear equation: -2y = x + 6 Graph A On a coordinate plane, a line goes through (negative 6, 0) and (1, negative 3). Graph B On a coordinate plane, a line goes through (0, 3) and (2, 4). Graph C On a coordinate plane, a line goes through (0, 3) and (2, 2). Graph D On a coordinate plane, a line goes through (0, negative 3) and (6, 0). a. Graph A c. Graph C b. Graph B
Answer:
i think its A
Step-by-step explanation:
divide both sides by -2 which makes the y int -3 and A has a negative slope

Find the median, first quartile, third quartile, and interquartile range of the data.
68, 74, 67, 72, 63, 70, 78, 64, 76
Given:
The data set is:
68, 74, 67, 72, 63, 70, 78, 64, 76
To find:
The median, first quartile, third quartile, and interquartile range of the data.
Solution:
We have,
68, 74, 67, 72, 63, 70, 78, 64, 76
Arrange the given data in ascending order.
63, 64, 67, 68, 70, 72, 74, 76, 78
Now divide the data in two equal parts.
(63, 64, 67, 68), 70, (72, 74, 76, 78)
So, the median of the given data set is 70.
Divide each parenthesis in two equal parts.
(63, 64), (67, 68), 70, (72, 74), (76, 78)
Now, the first quartile is:
[tex]Q_1=\dfrac{64+67}{2}[/tex]
[tex]Q_1=\dfrac{131}{2}[/tex]
[tex]Q_1=65.5[/tex]
The third quartile is:
[tex]Q_3=\dfrac{74+76}{2}[/tex]
[tex]Q_3=\dfrac{150}{2}[/tex]
[tex]Q_3=75[/tex]
The interquartile range (IQR) is the difference between third quartile and first quartile.
[tex]IQR=75-65.5[/tex]
[tex]IQR=9.5[/tex]
Therefore, median is 70, first quartile is 65.5, third quartile is 75 and the interquartile range is 9.5.

What is the domain of the function y = l n (x + 2)
A. x < -2
B. x > -2
C. x < 2
D. x > 2
Answer:
Option B.
Step-by-step explanation:
For a function f(x), the domain is the set of all the possible values of x that can be used in the function.
We know that the natural logarithm is only defined for positive real numbers.
So, the function:
Ln(x + 2)
Works always that
x + 2 > 0
So we can just solve this inequality for x, and that will give us the domain of the function.
To isolate x, we just need to subtract 2 in both sides of the inequality.
x + 2 - 2 > 0 - 2
x > - 2
This is the domain of the function.
The correct option is B.
Answer:
b.x>-2

Benji is writing some observations of different samples in his mineral collection. Which of the following terms can both be used to describe luster?
Group of answer choices

Shane uses a hand lens to examine a piece of granite rock. He observes that the granite is made up of very large crystals.
Group of answer choices
minerals
fossils
soils
shells
Answer: Hope This Helps!
Step-by-step explanation:
1: Igneous: Igneous rocks are formed by cooling magma. The location of the formation of the rock, as well as how fast the magma cools will determine the type of igneous rock.
2: Glassy and Metallic: Luster definition; the state or quality of shining by reflecting light; glitter, sparkle, sheen, or gloss: the luster of satin.
3: Minerals: The large mineral crystals in granite are evidence that it cooled slowly from molten rock material.

Function “p” is in the form y=ax^2 + C. If the values of “a” and “c” are both less than 0, which graph could represent “p”?
A. Graph A
B. Graph B
C. Graph C
D. Graph D
Answer:
B
Step-by-step explanation:
Since the value of a is less than 0, the graph of the parabola would be opening downwards. Because of this we can rule out option C. In a quadratic equation, c represents the y-intercept, and, in this case c is negative, meaning the y-intercept is less than 0. Only option B has a downward-opening curve and a y-intercept less than 0, so it is the answer.
Answer:
B. Graph B

At Edison Middle School, 54.4% of the
72
students chose chicken tacos as their
favorite school lunch, and 36% chose fish
tacos. There are 750 students in the
school. How many did NOT choose a type
of taco?
PLZ HELPP (7th grade math) ASSAAPPP
Answer:
6.912 students did NOT choose a taco type out of the 72 students.
Step-by-step explanation:
I got the number of kids for 54.4% of 72 and 36%, and added them, then subtracted that from 72 to get the total amount
750 - 750 * 0.544 - 750 * 0.36 = 72.

What is the average rate of change of f(x) on the interval [-3, -1]?
Answer:
To get a more specific answer, you'll need a specific function formula.
Step-by-step explanation:
The average rate of change in a function is the slope of a segment connecting two points on the graph of the function. If a formula (rule) for the function is given, then a graph is not usually necessary.
Example: Given the function [tex]f(x)=x^2[/tex], what is the average rate of change on the interval [tex][-3,1][/tex]?
Find the value of the function at each endpoint.
[tex]f(-3)=9\\f(-1)=1[/tex]
Then find
[tex]\frac{f(-1)-f(-3))}{-1-(-3)}=\frac{1-9}{-1+3}=\frac{-8}{2}=-4[/tex]
The average rate of change in f on the interval is 4.

A flower box is 3 ft. Long, 2 3/4 ft. Wide, and 1/2 ft. Deep. How many cubic feet of dirt can it hold? A. 4 1/8 B. 5 3/4 C. 6 1/2 D. 6 3/8
Answer:
The box can hold 4 1/8 cubic feet of dirt
Step-by-step explanation:
What we simply have to find here is the volume of dirt it can take
To get this, we have to multiply the dimensions of the box
We have this as follows
Volume or box = length * width * height
Volume of box = 2 3/4 * 1/2 * 3
Volume of box = 11/4 * 3 * 1/2 = 33/8 = 4 1/8 cubic feet
find the rate of change
