Answer:
16
Step-by-step explanation:
Write the expression in algebraic form:
3x² + 4y²
Notice we only have variables "x" and "y".
Given these variables: x = 2, y = 1, and z = –3
We can <u>ignore "z"</u> because the variable is not in the equation.
<u>Substitute</u> x = 2 and y = 1 in the expression. In other words, replace "x" and "y" with the numbers they give you.
3x² + 4y²
= 3(2)² + 4(1)²
Then, simplify the expression. Remember to follow <u>BEDMAS order</u> (brackets, <u>exponents</u>, division and <u>multiplication</u>, <u>addition</u> and subtraction).
= 3(2)² + 4(1)² Solve exponents first
= 3(4) + 4(1) Solve multiplication
= 12 + 4 Solve addition
= 16 Answer
The value of 3 x squared plus 4 y squared is 16, if x = 2, y = 1, and z = -3.
Answer:
$730.08
Step-by-step explanation:
22% = 0.22
1 - 0.22 = 0.78
Value after 2 years
v = 1200(0.78)²
v = 730.08
$730.08
Answer:
Infinitely many solutions (or 2=2 which isnt related)
Step-by-step explanation:
2+4x=4x+2
Distribute the 2 to the numbers inside.
Secondly, Minus the 4x on the right side and also minus the 4x on the right side.
You would end up with 0x.
The answer would be 2=2, but the real answer would be "infinitely many solutions."
If your teacher thinks this is wrong, I don't know what else. I could be wrong but really, I don't care.
C + 9 because you are adding o mode cars and an expression doesn't have an equal sign (=)
No association because the dots are just scattered all over the graph
Negative association would be when the dots are going toward downwards
Positive association would be when the dots are going toward upwards
