Answer:
(-2, -3)
(3, 12)
Step-by-step explanation:
To solve this, we're gonna get rid of the y's with substitution
x² + 2x - 3 = 3x + 3
Let's make this equation equal to zero
Subtract 3 from both sides
x² + 2x - 3 = 3x + 3
- 3 - 3
x² + 2x - 6 = 3x
Subtract 3x from both sides
x² + 2x - 6 = 3x
- 3x - 3x
x² - x - 6 = 0
Factor the equation
(x - 3)(x + 2) = 0
This means x can be -2 or 3
Let's solve it with -2 first, plug the new x in y = 3x + 3
y = 3(-2) + 3
y = -6 + 3 = -3
Do the same for x = 3
y = 3(3) + 3
y = 9 + 3 = 12
Answer:
32
Step-by-step explanation:
You use angle chasing. Since a triangle's angle has to add up to 180, the other angle is 180-79-69. This gives 32. So angle E is 32 degrees. Since they are parallel, that means that E equals to D. That means that D is 32, so 32 is now the answer.
HAPPY NOW BRAINLY? I JUST DIDN'T ADD AN EXPLANATION ON THE OTHER ONE AND YOU DELETED IT! I GOT BRAINLIEST! HE STILL GOT THE ANSWER ANYWAYS.
Answer:
if she question 1 spend $25 out of the $150, then you would do 150 sub 25 to get 125
Kevin has 10 signs. he's adding 5 signs, so divide 10 to 5 to get 2
Harvey has 5 in 1 minute, i would say in 2 minutes he'll have 10
Fran adds $25 to her $150 then she'll get $175.
Step-by-step explanation:
P= Parentheses
E= Exponent
M= Multiplication
D= Division
A= Addition
S= Subtraction

FIRST PROBLEM AS GENIUS!!!
The 45-45-90 triangle theorem states that each leg equals x, and the hypotenuse equals
. Using this, we can find that the height is 10. Take the average of the lengths to get l = 27.
The area = 270.
Area of square = a^2 = 4^2 = 4 x 4 = 16
answer
16
