Answer:
x=6 and y=0
Step-by-step explanation:
1. 15-3=12
2. 12÷2=6 6=x
3. 6-6=0 0=y
Answer:
8
Step-by-step explanation:
1) Divide both sides by 2
2x+12^2/3 =16
2) Solve the exponent
2x+12^2/3 =16
(2x+12^2/) ^3/2 =16^3/2 ( raise both sides to power)
2x+12 = 64
3) Subtract 12 from both sides
2x + 12 - 12 = 64-12
2x = 52
4) divide both sides by 2
2x/2 = 52/2
x = 26
Final answer : x = 26
X is the number
<span>The sum of two numbers is 11, so other number is : 11 - x
</span><span>The sum of their squares is 65
</span>
x^2 + (11 - x)^2 = 65
x^2 + 121 - 2(x)(11) + x^2 = 65
2x^2 - 22x + 121 = 65
2x^2 - 22x + 121 - 65 = 0
2x^2 - 22x + 56 = 0
2(x^2 - 11x + 28) = 0
2(x - 7)(x -4 ) = 0
x - 7 = 0
x = 7
x - 4 =0
x =4
answer: the numbers are 4 and 7
double check:
<span>sum of two numbers is 11:
4 + 7 = 11
</span><span>The sum of their squares is 65
</span><span>4^2 + 17^2 = 16 + 49 = 65

Answer:
y = -4x + 5.
Explanation:
Count rise/run to find the slope, find the y-intercept.
