Answer: Third multiple choice

Step-by-step explanation:

First answer:

Since the fraction is increased by 7, we need to check if the increasing factor is the same for the bottom part of the fraction:

$2.54*7=17.78\neq 17.68$

The first answer doesn't match, we do the same for all three remaining answer.

2) $12*7=84\neq 74$

3) $36*7=252$

4) $3.28*7=22.96\neq22.86$

In this case, the answer is the third multiple choice.

Use t = 4x + 1 to write the parametric equations that can represent y = 12x + 5.

e-lub [12.9K]

Answer:

Answer C: $x=\frac{t-1}{4}$ and $y=3t+2$

Step-by-step explanation:

Solve for x in the first equation given:

$t=4x+1\\t-1=4x\\\frac{t-1}{4} = x\\$

Now use this expression to replace x in terms of t in the second equation:

$y=12x+5\\y=12(\frac{t-1}{4}) +5\\ y=3(t-1)+5\\y=3t-3+5\\y=3t+2$

Factor completely 3x^4 - 3x ^3 - 18x ^2. Which of the following is one of the factors?

Otrada [13]

Answer:

$3x^4 - 3x ^3 - 18x ^2=3x^2(x+2)(x-3).$

Step-by-step explanation:

The expression $3x^4 - 3x ^3 - 18x ^2$ consists of three terms:

$3x^4;$
$-3x^3;$
$-18x^2.$

These three terms have common factor $3x^2.$ Thus,

$3x^4 - 3x ^3 - 18x ^2=3x^2(x^2-x-6).$

Consider the expression $x^2-x-6.$ You can rewrite it as

$x^2-x-6=x^2+2x-3x-6=x(x+2)-3(x+2)=(x+2)(x-3).$

The whole expression takes look

$3x^4 - 3x ^3 - 18x ^2=3x^2(x+2)(x-3).$

Find the equation of the circle whose center is at (4, 5) and that contains (13, −1).

zepelin [54]

The equation of circle is
(x-4)^2+(y-5)^2=R^2
if you replace the (13, -1) with x and y the R^2 will be 117
(x-4)^2+(y-5)^2=117
