You plug in x = 1 and y = -4 into the system of equations and see if they fit:-
y = -4x
- 4 = -4 * 1 = -4 This fits
y = 2x - 2
-4 = 2*1 - 2 = 0 Does NOT fit.
So (1, -4) is not a solution.
540 is the answer because the doubled the first number to get the second number and multiplyed that by 3 to get the third number

There are 22 large cups in total
And 5 cold large cups in total
There is a 5 in 22 chance it will be cold
5/22 put into decimal form is 22.7273%
Rounded to the nearest % is 22.7
A linear equation is an equation in which the highest power of the variable is always
Answer:
Surface area is, 478 square centimeter
Step-by-step explanation:
Surface area (S)of rectangle is given by:
.....[1]
where,
l is the length
w is the width
h is the height of the rectangle respectively.
As per the statement:
A rectangular solid has sides of 7 cm, 9 cm, and 11 cm
⇒ l = 7 cm , w = 9 cm and h = 11 cm
Substitute in [1] we have;

⇒
Therefore, the surface area is, 478 square centimeter
