Answer:

Y = a(x-h)^2 +k

Step-by-step explanation:

The first one, since the vertex form is in subtraction form. You need the a, the x, the h, and the k for the formula.

Answer:

y=a(x-h)^2+k

Step-by-step explanation:

This is the answer because numbers in the -h and k is the vertex point in this form.

e.g. y=2(x-4)^2+5

the vertex here is (4,5)

(btw, for h, when there's a negative sign in front of it, it's the opposite and when there's a plus sign in front of h, it's the opposite.)

Answer:

10 1/4

Step-by-step explanation:

Carls age = 12 5/6 - 1 1/3

12 5/6 - 1 1/3

11 (5 - 2) / 6 = 11 3/6

Jane's age = carl's age - 1 1/4

11 3/6 - 1 1/4

10 (12 - 6) / 24 = 10 6/24 = 10 1/4

Answer:

(2x-7)^2

Step-by-step explanation:

you need to find two numbers that add up to -28, but multiply to 196, so -14, then spread out your equation and sub in -14, then divide out common factors, and then you have your answer

if you have any questions, leave them in the comments, i will try to answer them, if this helped, pls give brainliest

Answer:

[tex]g(x)=4x^2-28x+49[/tex]

[tex]=4(x^2-7x)+49[/tex]

[tex]=4(x^2-7x+(7/2)^2-(7/2)^2)+49[/tex]

[tex]=4(x-7/2)^2+4(-(7/2)^2)+49[/tex]

[tex]=4(x-7/2)^2+4(-49/4)+49[/tex]

[tex]=4(x-7/2)^2+0[/tex]

[tex]4(x-7/2)^2+0[/tex]

-------------------------------

so,

[tex]g(x)=4(x-7/2)^2+0[/tex]

Answer:

8:18

Step-by-step explanation:

Answer:

-22/9

Explanation:

Just turn -2 4/9 into an improper fraction. 2 x 9 = 18 and 18 + 4 = 22.

22/9, and just add the negative sign to make it -22/9.

Try this process when you see a right triangle

Answer:

a) A =( x^2 -4x)/2

b) 16 cm^2

Step-by-step explanation:

Let the base of the triangle be x cm

since it is longer, then the height would be (x-4) cm

Mathematically, the area of a triangle is the product of the base and the height divided by 2

So, we have this as;

A = 1/2(x-4)x

A = x(x-4)/2

A = (x^2 - 4x)/2

A =( x^2 -4x)/2

To find the area, we only need to substitute 8 cm for x

we have this as;

A = (8^2 -4(8))/2

A = (64-32)/2 = 32/2 = 16 cm^2

We will begin by converting the word problem to relatable mathematical expression in the first part, in the second part, we will substitute for x and find the area which is 48cm^2

Given data

Let the height be x cm

and let the base be y cm

Going by the word problem statement "base that is 4cm longer than its height."

y = x+4

a. the polynomial expression for the area of the triangle is

We know that the area of triangle is given as

Area = 1/2*Base*Height

Area = 1/2*(x+4)*x

Area = 1/2*x^2+4x

Simplify

Area = x^2/2 + 2x

b. The Area when the height is 8cm

We will substitute x= 8cm

Area = (8)^2/2 + 2(8)

Area = 64/2 +  16

Area = 32+16

Area = 48 cm^2
