A quadratic equation has an axis of symmetry at x = 7 and has a
maximum value at -3. Write the equation.
g(x) = -3(x – 7)?
O g(x) = -(x + 7)2 – 3
O g(x) = -(x – 7)2 – 3
og(x) = (x – 7)2 – 3

Answers

Answer 1

Answer:

g(x) = (x - 7)² - 3

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (7, - 3) and a = 1, thus

g(x) = (x - 7)² - 3

If ∆TIK ≅ ∆TOK and < I = (5x + 8), < K = 92, and < O is 50. What is the measure of < I?

Answers

Answer:

<I = 50

Step-by-step explanation:

Sum of angles in ∆TOK is 180

Given

< I = (5x + 8),

< K = 92, and

< O is 50.

<T + <O+<K = 180

<T +92+50 = 180

<T + 142 = 180

<T = 180-142

<T = 38

Also <T+<I+<K = 180

38+5x+8+92 = 180

5x+138 = 180

5x = 42

x = 42/5

x = 8.4

Since <I = 5x+8

<I = 5(8.4)+8

<I = 42 + 8

<I = 50

=50

How do you do
3x-5y=-2
x+3y=4
Please show work

Answers

3x-5y=-2
-3(x+3y=4)
You multiply the whole equation by three so you can cancel out the three x
3x-5y=-2
-3x-9y=-12
Now you can cancel out the 3x
-5y=-2
-9y=-12
Now add them together
-14y=-14
So y=1

Oliver has of a gallon of water. He pours all of the water into 6 containers. If he pours the same amount of water into each container, how many gallons of water does Oliver pour into each container?

Answers

Answer:

Step-by-step explanation:

because he pours it into 6 containers (which make each container hold 1/6 of a gallon)

then he pours the same amount again which will make it 2/6 of a gallon and 2/6 simplified is 1/3

3x+ 2y= 14 4x- 2y= 16 Elimination.

Answers

If you set the problem like you are going to add it, it will look like this:

3x+2y=14
+4x-2y=16
——————

2y+(-2y) will cancel out leaving you with:

7x=30

Divide by seven to get x by itself, you will get:

x=5

Now plug that in to 4x-2y=16

4(5)-2y=16

20-2y=16

Minus 20 on both sides

-2y=16

Divide by -2 to get y by itself

y=8

Thus,

x=5 and y=8

Find the slope of the line that passes through the points. (10,8) and (4,12) is as a simplified fraction

Answers

Answer:

- 2/3

Step-by-step explanation:

Slope m = (y2-y1) / (x2-x1)

= (12-8) / (4-10)

= 4 / (-6)

= - 2/3

The slope as a simplified fraction is : - [tex]\frac{-2}{3}[/tex]

Meaning of slope

Slope or gradient is the degree of steepness of a line.It is the ratio of the chance in the y- coordinates to the change in the x-coordinates of a line.

m( slope) = [tex]\frac{y2-y1}{x2-x1}[/tex]

Given data

x1 = 10, x2 = 4, y1 = 8, y2 = 12

Therefore the slope can be calculated as :

m = [tex]\frac{y2-y1}{x2-x1}[/tex]

m = [tex]\frac{12-8}{4-10}[/tex] = -4/6 = -2/3

In conclusion the slope of the points (10,8) and (4,12) as a simplified fraction is -2/3
