One way to find a common denominator is by

Lena [83]

Answer:

Step-by-step explanation:

a). $1\frac{3}{5}=1+\frac{3}{5}$

$=1+\frac{3}{5}\times \frac{4}{4}$

$=1+\frac{12}{20}$

$=1\frac{12}{20}$

$1\frac{3}{4}=1+\frac{3}{4}$

$=1+\frac{3}{4}\times \frac{5}{5}$

$=1+\frac{15}{20}$

$=1\frac{15}{20}$

Therefore, common denominator of 20.

b). $2\frac{1}{2}=2+\frac{1}{2}$

$=2+\frac{1}{2}\times \frac{5}{5}$

$=2+\frac{5}{10}$

$=2\frac{5}{10}$

$\frac{4}{5}=\frac{4}{5}\times \frac{2}{2}$

$=\frac{8}{10}$

Common denominator of 10.

c). $\frac{3}{8}=\frac{3}{8}\times \frac{6}{6}$

= $\frac{18}{48}$

$\frac{1}{6}=\frac{1}{6}\times \frac{8}{8}$

= $\frac{8}{48}$

Common denominator of 48.

Consider the quadratic function f(x) = x2 – 5x + 12. Which statements are true about the function and its graph? Select three op

Rashid [163]

Answer:

I will assume the equation is supposed to be f(x) = <u>x^2</u> – 5x + 12 since it is said to be a quadratic equation.

Step-by-step explanation:

<u>See attached graph.</u>

The value of f(–10) = 82 <u><em>False</em></u>

f(-10) = (-10)^2 - 5*(-10) + 12

f(-10) = (100) +50 + 12

f(-10) = 162

The graph of the function is a parabola. <u><em>True</em></u>

The graph of the function opens down. <u><em>False</em></u>

The graph contains the point (20, –8). <u><em>False</em></u>

The graph contains the point (0, 0). <u><em>False</em></u>

scoundrel [369]

Hey You!

12/40 = Candidate A.

18/40 = Candidate B.

12 + 18 = 30

40 - 30 = 10

10/40 = Those who didn't vote.

ANSWER:

12 ÷ 40 = .3 (30%) So 30% voted for Candidate A.

18 ÷ 40 = .45 (45%) So 45% voted for Candidate B.

10 ÷ 40 = .25 (25%) So 25% didn't vote at all.

What is f(-1)? Show your work.<br><br> Question 4 options:

adelina 88 [10]

F(-1) = 3

How did I figure this out?

f(-1) is substituted for f(x) so you must look at -1 on the x axis.

Once you've located -1 on the x-axis, locate what it equals to answer the question.

The answer should be the y-axis number that corresponds to -1 which is 3.
