The vertex of the parabola below is at the point (3,2) and the point (4,6) is on the parabola. What is the equation of the parab
nata0808 [166]

Answer:

\large\boxed{y=4(x-3)^2+2\ \bold{vertex\ form}}\\\boxed{y=4x^2-24x+38\ \bold{standard\ form}}

Step-by-step explanation:

The vertex form of a parabola:

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

(h, k) - vertex

We have the vertex at (3, 2) → h = 3 and k = 2.

Substitute:

y=a(x-3)^2+2

The point (4, 6) is on athe parabola. Put the coordinates of this point to the equation:

6=a(4-3)^2+2       <em>subtract 2 from both sides</em>

6-2=a(1)^2+2-2

4=a\to a=4

Finally:

y=4(x-3)^2+2          <em>vertex form</em>

<em>use (a - b)² = a² - 2ab + b²</em>

y=4(x^2-6x+9)+2          <em>use the distributive property</em>

y=4x^2-24x+36+2

y=4x^2-24x+38             <em>standard form</em>

Operation for <br><br>w/7 = 14<br><br>addition<br>subtraction<br>multiplication<br>division​
NikAS [45]

Answer: Multiplication

Step-by-step explanation:

Given

w/7=14

Multiply 7 on both sides

w/7 × 7=14 × 7

w=98

In order to isolate w on one side, we should times 7 as the numerator in order to eliminate the 7 in the denominator. To promise equality, we need to multiply 7 on both sides in order to isolate w and solve the equation.

<h2>Thus, it is multiplication.</h2>

The sum of the digits of a two-digit number is 11. When the digits are reversed, the new number is 45 more than the original num
Crank

Answer:

Step-by-step explanation:

Let the 10s digit = x

Let the units digit = y

x +y = 11                                   Sum of the digits = 11

10x + y + 45 = 10y + x             Reversed number is 45 more  than original #

10x - x + y + 45 = 10y              We subtracted x from both sides.

9x + y + 45 = 10y                    Subtract y from both sides.

9x + 45 = 10y - y                     Combine the right

9x + 45 = 9y

Put x +  y = 11 into the equation just found.

9x + 45 = 9(11 - x)                     divide through by 9

x + 45/9 = 11 - x                        add x to both sides

2x + 5 =     11                            Subtract 5 from both sides

2x = 11 - 5

2x = 6                                       Divide by 2

x = 6/2

x = 3

x + y = 11

3 + y = 11        

y = 11 - 3

y = 8

Now check it out.

the original number is 38

the new number is 83 which the digits are reversed.

83 - 38 = 45 just as it should.
