Answer:

x=-13

Step-by-step explanation:

If we have a quadratic function and the vertex is

(h,k) then our axis of symmetry is x=h.

So here our axis of symmetry is x=-13

Its simple, graph them.

For the first equation, go on the Y-Axis (the vertical one) and go to 4. Then from there go up 1, right 6.

For the second equation go on the Y-Axis (the vertical one) and plot a point at 1 (aka 0,1) Now you go up 1, right 3.

When you see an equation like y=2x+3, the 3 represents the point (0,3) as when the x is 0, y=3. Just plug the numbers in. And as for the "2x" 2 is the slope. Slope is always rise/run or up, then right. So if its 2 your slope is 2/1, rise 2, over 1. If it "-2x" is your slope then all you have to do is go down 2, right 1.

I hope this cleared up your confusion, brainliest/heart would help.

Licemer1 [7]

Answer:

1/12

Step-by-step explanation:

Since 1/4 drank fanta orange and 1/3 took coca cola, the. remainder will be:

= 1 - (1/4 + 1/3)

= 1 - 7/12

= 5/12

Therefore, 1/5 of the remainder drank sprite, the fraction that drank sprite will be:

= 1/5 × 5/12

= 1/12

Nat2105 [25]

Answer:

The number is -2

Step-by-step explanation:

12 less than 7 times a number can be express as follows,

let the number = a

7a - 12

According to the question the number 7a - 12 is equals to 32 less than the product of - 3 and the number.

32 less than the product of -3 and the number can be express below.

-3a - 32. Therefore,

7a - 12 = -3a - 32

collect like terms

7a + 3a = - 32 + 12

10a = -20

divide both sides by 10

a = -20/10

a = -2

The number is -2
