Solve for x
Ax + B = C

Answers

Answer:

(C - B)/A = x

Step-by-step explanation:

Ax + B = C

-B -B

Ax = C - B

Divide both sides by A

x = (C - B)/A

(C - B)/A = x

Identify the turning point of the function f(x)=x^2-2x+8 by writing its equation in vertex form.Show work

Answers

$f(x)=x^2-2x+8 \n \n To \ convert \ the \ standard \ form \ y = ax^2 + bx + c \n \n of \ a \ function \ into \ vertex \ form \n \n y = a(x - h)^2 + k \n \n Here \ the \ point \ (h, k) \ is \ called \ as \ vertex \n \n h=(-b)/(2a) , \ \ \ \ k= c - (b^2)/(4a)\n \n a=1 ,\ b=-2 , \ c = 8$

$h=(-b)/(2a)=(-(-2))/(2 )=(2)/(2)=1 \n\n k=c - (b^2)/(4a) =8 - ( (-2)^2)/(4 ) = 8-1 = 7 \n \n y= (x-1)^2 + 7 \n \n So \ the \ turning \ point \ is \ (1,7)$

Two lines, A and B, are represented by the following equations: Line A: 2x + 2y = 8
Line B: x + y = 3

Which statement is true about the solution to the set of equations?

It is (1, 2).
There are infinitely many solutions.
It is (2, 2).
There is no solution.

Answers

Line A: 2x+2y=8 ⇒2y=-2x+8 ⇒ y=-x+4
Line B: x+y=3 ⇒y=-x+3

Therefore: y=y then:
-x+4=-x+3
-x+x=3-4
0≠-1 ⇒There is no solution because the lines are parallels

Eisha is making trail mix. The ratio of raisins to granola in the mix is 2 to 5. If Eisha adds 4 cups of raisins to her trail mix, how many cups of granola should she add? A 5 cups C 10 cups

B 7 cups D 20 cups

Answers

2:5=rasins:granolas

if rasins=4
4=2 units
divid 2
2=1 uit

granola=5 units
1 unit=2
5 times 2=10

answer is 10 cups

answer is C 10 cups

The zeros of the function f(x)=(x+2)^2 - 25 are?

Answers

Zeros of the function
f(x) = (x + 2)² - 25
f(x) = (x + 2)(x + 2) - 25
f(x) = x(x + 2) + 2(x + 2) - 25
f(x) = x(x) + x(2) + 2(x) + 2(2) - 25
f(x) = x² + 2x + 2x + 4 - 25
f(x) = x² + 4x + 4 - 25
f(x) = x² + 4x - 21
x² + 4x - 21 = 0
x = -(4) +/- √((4)² - 4(1)(-21))
      2(1)
x = -4 +/- √(16 + 84)
   2
x = -4 +/- √(100)
   2
x = -4 +/- 10
2
x = -2 + 5
x = -2 + 5 x = -2 - 5
x = 3    x = -7
f(x) = x² + 4x - 21
f(3) = (3)² + 4(3) - 21
f(3) = 9 + 12 - 21
f(3) = 21 - 21
f(3) = 0
(x, f(x)) = (3, 0)
or
f(x) = x² + 4x - 21
f(-7) = (-7)² + 4(-7) - 21
f(-7) = 49 - 28 - 21
f(-7) = 21 - 21
f(-7) = 0
(x, f(x)) = (-7, 0)

Vertex
X - Intercept
-b/2a = -(4)/2(1) = -4/2 = -2

Y - Intercept
y = x² + 4x - 21
y = (-2)² + 4(-2) - 21
y = 4 - 8 - 21
y = -4 - 21
y = -25
(x, y) = (-2, -25)

y=x^2+4x+4-25
y=x^2+4x-21
y=(x+7)(x-3)
zeros are -7 and 3
