Step-by-step explanation:
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 + 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
Rewrite using a fractional exponent
[tex]\sqrt[3]{7^2}
Answer:
9π cm³
Step-by-step explanation:
We require to find the height (h) of the cylinders
The volume (V) is calculated as
Ah ( A is the base area and h the height ), then
3πh = 18π ( divide both sides by 3π )
= 6
Then the height of the smaller cylinder = 6 - 3 = 3 cm
3π × 3 = 9π cm³ ← volume of smaller can

Write an equation for a circle with center at (5,-2) and diameter of 8 centimeters.
I’ll give Brainlessly or whatever it’s called
Answer:
[tex](x-5)^2+(y+2)^2=16[/tex]
Step-by-step explanation:
lol brainlessly...
General Circle function: [tex](x-h)^2+(y-k)^2=r^2[/tex], where h is the x-coordinate of the center, k is the y-coordinate of the center, and r is the radius.
The radius of the circle is half the diameter so: 8 / 2 = 4
The x-coordinate of the circle is 5
The y-coordinate of the circle is -2
Plug in.
[tex](x-5)^2+(y-(-2))^2=4^2[/tex]
[tex](x-5)^2+(y+2)^2=16[/tex]

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:
We need to plug in -1 for x. Here's what we get:
[tex]-5(-1)+2[/tex] multiplying two negative numbers gives us a positive number
[tex]5+2[/tex]
= 7
Answer:
g(-1) = 7
Step-by-step explanation:
this is a function, when it says f(x) or g(x), whatever, and then gives, in this case g(-1), it wants you to substitute -1 into all the x values.
Therefore, our equation is g(-1)= -5 (-1) +2
this simplifies to g(-1)= 7
