If 2x+3y=6 and -5x+2y=4 then what is x and y??
Answers
Answer:
x=0 y=2
Step-by-step explanation:
2x+3y=6 .... 1
-5x+2y=4 .... 2
Multiply 5 with equation 1 and multiply 2 with equation 2
Then we get
10x+15y=30
-10x+4y=8
-10x and +10x get canceled so 19y=38
y=38/19=2
substitute y value in equation 1 or 2 and find the value to get x

PLEASE ACTUALLY HELP AND BE SERIOUS I DONT CARE IF YOU DONT KNOW THE ANSWER.
Answers
Volume is a three-dimensional scalar quantity. The volume of water through is 88 ft³.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
1. The measurement of A and B can be written as,
The value of A = 8ft - 3ft = 5ft
The value of B = 8ft - 4ft = 4ft
2. The volume of the water through = (8×3×2)+(5×4×2) = 48ft³+40ft³ = 88ft³
Hence, the volume of water through is 88 ft³.

Ruby says that 4/5 divided by 2/15 = 14/15. What error did Ruby make? A. Ruby added instead of divided. B. Ruby divided 2/15 by 4/5 instead of 4/5 by 2/15. C. Ruby divided by 2 instead of dividing by 2/15. D. Ruby multiplied by 2/15 instead of 15/2 multiplying by .
Answers
Answer:
A. Ruby added instead of divided
Step-by-step explanation:
You must find a common denominator (15), and then multiply by the reciprocal and simplify your final answer
12/15 times 15/2 equals 180/30 which, when simplified equals 6
Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.
What is simplification?Using mathematical operations it is to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
Ruby says that 4/5 divided by 2/15 = 14/15, which is incorrect.
4 / 5 divided by 2/15 is 6,
When we add both numbers,
= 2 / 15 + 4 / 5
= [2 + 12] / 15
= 14 / 15
Thus, Ruby added 4/5 and 2/15 instead of dividing. Option A is correct.

Linear: 3x +9 =2x
Non Linear: x+2y=1 and x = y
Answer:
Examples, solutions, videos, and lessons to help Grade 8 students learn how to interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear.
For example, the function A = s2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line.
