Answer:

x = -9

Step-by-step explanation:

2x - 3(2x - 3) = 45

2x - 6x + 9 = 45

-4x + 9 = 45

-4x + 9 - 9 = 45 - 9

-4x = 36

-4x/-4 = 36/-4

x = -9

2 1/4 x2 1/4 in mixed number
maks197457 [2]

Answer:

5 \frac{1}{16} is the answer.

Step-by-step explanation:

Given:

2 \frac{1}{4} \times 2 \frac{1}{4}

<u>Step 1: Converting the mixed fraction into  fraction:</u>

Multiply  4 by 2 add  1 to the result.

<u></u>2\frac{1}{4}  =  \frac{4 \times 2+1}{4}

=\frac{8+1}{4}

=\frac{9}{4}

<u>Step 2: Performing the multiplication using the fraction</u>

= >\frac{9}{4} \times \frac{9}{4}

=> \frac{81}{16}

<u>Step 3: Converting the product back to  mixed fraction </u>

divide 81 by 16 and find the remainder

=>quotient \frac{remainder}{divisor}

Dividing 81 by 16 we get  5 as quotient and 1 as remainder

Thus the result in  mixed fraction will be

=> 5 \frac{1}{16}

Use the function f(x) = −16x2 + 60x + to Completely factor f(x). <br>Pls include steps ​
Elodia [21]

Answer: -4x(4x - 15)

Step-by-step explanation:

f(x) = -16x^{2} + 60x

y = -16x^{2} + 60x

=> - (16x^{2} - 60x)

=> -4x(4x - 15)

determine the vertex and axis of symmetry for the following: f(x) = 2x to the power of 2 - 12x + 24 ?
Vikki [24]

Answer:

vertex = (3,24)  Axis of symmetry = 3

Step-by-step explanation:

Use the vertex formula to find x: x=-b/2(a)

x= 12/2(2) = 3 (this is your axis of symmetry)

Substitute 3 for x in the equation to get y: y = 42

Once you have both x and y you have your vertex.
