Answer:

Step-by-step explanation:

It's an isosceles triangle so it means two sides are equal or better term congruent .

So PR is equal to PQ

You can write

X+1=2x+1

Solve the equation

2x+1-x-1=0

X=0

In order to find PQ plug X in place of 2x+1

To find

QR do the same for its expression .

Find the perimeter of the figure. round all figures to the nearest hundredth Place
slavikrds [6]

Answer:

C

Step-by-step explanation:

The perimeter of a figure is found by adding the sides of all the figures. The figure has sides 13 and 9. Its height is 4 so each of those sides is about 4 feet. So the perimeter is 13+9+4+4 = 30

C is the best solution.

-| 15| simplify the expression
Viefleur [7K]

Answer:

-15

Step-by-step explanation:

The negative is outside of the absolute value signs/lines. The absolute value is how far the number is from 0. So, it doesn't matter whether or not there is a negative sign inside of the absolute value lines it will always be positive. But, if it's outside of it, then it will be negative.

Use the method of completing the square to write the equation of the given parabola in this form:
siniylev [52]
Formula is y = a(x-h)^2 + k

Where h is 1 and k is 1

f (x) = a(x-1)^2 + 1

-3 = a(0-1)^2 + 1

-3 = a(-1)^2 + 1

-3 = a(1) + 1

-3 - 1 = a

-4 = a

a = -4

A must be equal to -4

y = -4(x-1)^2 + 1

0 = -4(x-1)^2 + 1

4(x^2 - 2x + 1) - 1 = 0

4x^2 - 8x + 4 - 1 = 0

4x^2 - 8x + 3 = 0

4x^2 - 8x = -3

Divide fpr 4 each term of the equation....x^2 - 2x = -3/4

We must factor the perfect square ax^2 + bx + c which we don't have. We must follow the rule (b/2)^2 where b is -2....(-2/2)^2 = (-1)^2 = 1 and we add up that to both sides

x^2 - 2x + 1 = -3/4 + 1

x^2 - 2x + 1 = 1/4

(x-1)^2 = 1/4

square root both sides x-1 = (+/-) 1/2

x1 = +1/2 + 1 = 3/2

x2 = -1/2 + 1 = 1/2

x-intercepts are 1/2 and 3/2, in form (3/2,0); (1/2,0)
