Hi help me (2·4)²= this is other (6:2)²+
Answers
Answer:
(2·4)² = 64 / (6*2)² = 144
Step-by-step explanation:
Follow PEMDAS :
Parenthesis first, so:
2 * 4
==> 8
Then Exponent:
8 ^2
==> 64
(2·4)² = 64
Do the same for (6:2)² :
Parenthesis first :
6 * 2
==> 12
Then Exponent:
12^2
==> 144
(6:2)² = 144
Answer:
1. 64 is the answer.
2. 144 is the answer
Step-by-step explanation:
First, multiply the numbers inside the parenthesis. So
1. 2*4 = 8
2. 6*2 = 12
Next, Use the exponents
1. 8^2
2. 12^2
Finally, solve using exponents.
1. 8^2 = 64
2. 12^2 = 144
So 64 and 144 is the answer.

(I have a graphing calculator capble of matrices so yo don't have to solve the system of equations by hand, use rref (reduced row echelon form))
values of a, b, and c and the equation of the graph of the parabola
y=ax^2+bx+c
such that is passes through the points
(2,-15)
(-5,-29)
(-3,5)
rewrite it in the form (x-h)^2=4P(y-k)
show all work
if I were to sub the points in I would ge
(2,-15): -15=4a+2b+c
(-5,-29): -29=25a-5b+c
(-3,5): 5=9a-3b+c
then solve for a, b and c
I don't know how to solve, please help
(if I don't undestand your answer, I will either report or ask you to explain more)

y =ax² + bx + c
Since parabola passes through the point (2,−15) then
−15 = 4a + 2b + c
Since parabola passes through the point (-5,-29), then
−29 = 25a − 5b + c
Since parabola passes through the point (−3,−5), then
−5 = 9a − 3b + c
Thus, we obtained following system:
4a + 2b + c = −15
25a − 5b + c = −29
9a − 3b + c = −5
Solving it we get that
a = −2, b = −4, c = 1
Thus, equation of parabola is
y = −2x²− 4x + 1

Rewriting in the form of
(x - h)² = 4p(y - k)
i) -2x² - 4x + 1 = y
ii) -3x² - 7x = y - 11
(-3x² and -7x are isolated)
iii) -3x² - 7x - 49/36 = y - 1 - 49/36
(Adding -49/36 to both sides to get perfect square on LHS)
iv) -3(x² + 7/3x + 49/36) = y - 3
(Taking out -3 common from LHS)
v) -3(x + 7/6)² = y - 445/36
vi) (x + 7/6)² = -⅓(y - 445/36)
(Shifting -⅓ to RHS)
vii) (x + 1)² = 4(-1/12)(y - 445/36)
(Rewriting in the form of 4(-1/12) ; This is 4p)
So, after rewriting the equation would be -
(x + 7/6)² = 4(-⅛)(y - 445/36)

The y-intercept is 4.
What is linear equation?
A linear equation is defined as an equation in which the highest power of the variable is always one.
GIven equation,
y = 7x+4
Comparing to the equation of Line y=mx+b,
Whereas the y-intercept is the b.
So, 7 is the slope and 4 is the y-intercept
Hence the y-intercept is 4.
