Can someone explain what to do

Mathematics
1 answer:
castortr0y [4]2 years ago
7 0

Answer:

8

Step-by-step explanation:

The equation of the parabola can be represented as

y = a(x + 1)(x - 5)

for some constant a.

Since the coefficient of x² is 2, a = 2, so

y = 2(x  + 1)(x - 5) \\  \\ y = 2( {x}^{2}  - 4x + 5) \\  \\ y = 2 {x}^{2}  - 8x + 10

So, the answer is 8.

Answer:

1. 14/15

2. 5 7/8

3. 81.25%

Step-by-step explanation:

1. (fraction) 7/9 divided by 5/6 (fraction)

7/9 ÷ 5/6 =

= 7/9 * 6/5

= (7 * 6)/(9 * 5)

= 42/45

= 14/15

2.

1 3/8 + 4 1/2 =

= 1 + 3/8 + 4 + 1/2

= 1 + 4 + 3/8 + 4/8

= 5 + 7/8

= 5 7/8

3.

percent = part divide by whole times 100

13/16 * 100 =

= 81.25%

PLEASE HELP I WILL MARK!!
Rina8888 [55]

answer is D

Explamation:

given points are (7,9) and (12,11)

mid \: point \: of \: x =  \frac{x1 + x2}{2 }  =  \frac{7 + 12}{2}  = 9.5 \\ midpoint \: of \: y =  \frac{y1 + y2}{2}  =  \frac{9 + 11}{ 2} = 10

therefore the mid point is (9.5,10)

The coordinates of A and B are (3k, 8) and (k, -3) respectively. Given that the gradient of the line segment AB is 3, find the v
Vladimir [108]

Step-by-step explanation:

gradient = slope or several other words.

it describes how strongly a line (or tangent to a bent curve) is going up or down or ... if it is changing at all.

it is represented by the ratio

(y coordinate change / x coordinate change)

when going from one point on the line to another.

in our case, when going from A to B we have

x changes by -2k (from 3k to k).

y changes by -11 (from 8 to -3).

so, the gradient or slope is

-11/-2k = 3

11/2k = 3

11 = 3×2k = 6k

k = 11/6

A = (33/6, 8) = (11/2, 8)

B = (11/6, -3)

PilotLPTM [1.2K]

Answer:

If g(x) is a translation of f (x) =x^2 right by 5 units and down 3 units which is g(x) ? Please help me ASAP
Contact [7]

Answer:

C

Step-by-step explanation:

Given f(x) then f(x + h) represents a horizontal translation of f(x)

• If h > 0 then a shift to the left of h units

• If h < 0 then a shift to the right of h units

Here the shift is 5 units right, thus g(x) = (x - 5)²

Given f(x) then f(x) + c represents a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here the shift is 3 units down, thus g(x) = f(x) - 3

Hence

g(x) = (x - 5)² - 3 → C
