How many roots do u thinn

Mathematics
1 answer:
hram777 [196]3 years ago
6 0

Answer:

  • 2 roots
  • 1 root

Step-by-step explanation:

Each equation is in vertex form, so you can easily determine the number of real roots. The leading coefficient tells you whether the parabola opens upward (positive) or downward (negative).

  y = a(x -h)^2 +k

has leading coefficient "a" and vertex (h, k).

__

<u>f(x) = 1/3(x +5)^2 +7</u>

  vertex: (-5, 7), opens downward

The vertex is above the x-axis, so there are two real roots.

__

<u>f(x) = -5(x -3)^2</u>

  vertex: (3, 0), opens downward

The vertex is on the x-axis, so there is one real root.

I'd say option D because you can just tell right off the bat that if x = 0, then f(x) = 43.75.

How do i solve divide 5/8 by 50%
Ede4ka [16]
50% is \frac{50}{100}
We have two ways to do this, pick your favor:
either by fractions:
\frac{5}{8} ÷ \frac{1}{2}
(\frac{50}{100} =  \frac{1}{2}
Multiply by the reciprocal of \frac{1}{2} which is 2(flip it)

\frac{5}{8} × 2 = \frac{5}{4} = 1.25

Or change them to decimals:
\frac{5}{8} = 0.625
\frac{50}{100} = 0.5

0.625 ÷ 0.5

0.5 I 0.625
multiply by 10 to make it easier to divide(it still gives us the same answer)
0.5 × 10 = 5
0.625 × 10 = 6.25
     1.25
5 I 6.25
    -5
     12
    -10
       25
      -25
         0

0.625 ÷ 0.5 = 1.25

PLEASE ANSWER ASAP CORRECT ANSWER GETS BRAINLIST
geniusboy [140]

I guess the number 2 is to indicate the question...

Then the equation would be 1/3 - 1/2x = -2/3

1/3 - 1/2x - 1/3 = -2/3 - 1/3

-1/2x = -3/3

-1/2x = -1

-1/2x *2 = - 1*2

-x = -2

-x * -1 = -2 * -1

x = 2

Good luck
