Answer = B) x = 2, y = 1
As, x + 3y = 5 = 2 + 3(1) = 5, so 2 + 3 = 5
-x + 6y = 4
-2 + 6(1) = 4
-2 + 6 = 4
So, answer = (B)

z varies jointly with w, x, and y. z=24 when w=2, x=3, and y=8.
Answer:29739
Step-by-step explanation:
neosbs elenelend sidn
if z varies jointly with w, x, and y. z=24 when w=2, x=3, and y=8 then z=1/2wxy
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
z varies jointly with w, x, and y
z=kwxy
Where k is constant.
k=z/wxy
Now plug in values of z=24, w=2, x=3, and y=8.
k=24/2.3.8
k=24/48
k=1/2
So z=1/2wxy
Hence, if z varies jointly with w, x, and y. z=24 when w=2, x=3, and y=8 then z=1/2wxy

Jalil and Victoria are each asked to solve the equation ax – c = bx + d for x. Jalil says it is not possible to isolate x because each x has a different unknown coefficient. Victoria believes there is a solution, and shows Jalil her work:
Answer:
[tex]x=\frac{d+c}{a-b}[/tex]
Step-by-step explanation:
The equation is:
a x - c = b x + d
so we subtract b x from both sides to group the terms that contain x on the left:
a x - b x - c = d
add c to both sides to isolate the terms in x on the left:
a x - b x = d + c
extract "x" as common factor on the left using distributive property backwards:
x (a - b) = d + c
divide both sides by the quantity (a - b) to isolate the "x":
x = (d + c) / (a - b)
or: [tex]x=\frac{d+c}{a-b}[/tex]
When the value of the y-intercept(b) change by subtracting a number from "b" in the equation "y=mx+b", the graph will move of shift down ? true or false
Answer:
True. The graph will shift down if we subtract a number from "b"
Step-by-step explanation:
"b" represents the y-intercept, or how high up on the y axis the graph intersects.
If we don't change anything except for the y-intercept, then the graph should only move up or down.
Because we are decreasing the value of "b" the y intercept will decrease, dragging the graph of y down.

Marcelina uses a blend of white corn and yellow corn to make tortilla chips at her restaurant. She needs to buy
50 kg of corn in total for her next order. White corn costs $0.30 per kilogram, yellow corn costs $0.15 per
kilogram, and she wants to spend $12 total.
Here's a graph that shows a system of equations for this scenario where is the amount of white corn she buys
and y is the amount of yellow corn she buys.
What does D represent in this context?
CORRECT (SELECTED)
Marcelina spends less than the intended amount of money and buys the correct amount of corn.
Point DDD is below line aaa, so it represents a scenario where she spends less than \$12$12dollar sign, 12. Also, point DDD is on line bbb, so it represents a scenario where she does buy 50\,\text{kg}50kg50, start text, k, g, end text of corn.

Marcelina spends less than the intended amount of money and buys the correct amount of corn.
What is an equation?An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
The system of equations for the given scenario is:-
0.30x + 0.15y = 12
x + y = 50
Point D is below line a, it represents a scenario where she spends less than $12. Also, point D is on line b, it represents a scenario where she does buy 50kg of corn.

If f(x) = -x^2 + 6x - 1 and g(x) = 3x^2 - 4x-1, find (f - g)(x).
A. (f- g)(x) = -4x^2 - 2x
B. (f- g)(x) = 2x^2 + 2x-2
C. (f- g)(x) = 4x^2 - 10x
D. (f - g)(x) = -4x^2 + 10x
Answer:D
Step-by-step explanation:
(f-g)(x)= -x^2+6x-1- (3x^2-4x-1)
(f-g)(x)= -x^2+6x-1 -3x^2+4x+1
(f-g)(x)= -x^2-3x^2+6x+4x-1+1
(f-g)(x)= -4x^2+10x
