Y = -5x -5

To check, we can insert 0 for y and -1 for x

0 ? (-5X-1) - 5
0 ? 5 - 5
0 = 0

So yes, the equation is correct

Fatima earned an 85 average in her science class. The average is based on 6 tests that she takes over the span of the marking pe

Answer:

Fifth Score = 87

Sixth Score = 95

Step-by-step explanation:

Given

$Average = 85$

$Scores = 83, 78, 87, 80$

$Fifth\ score = x$

$Sixth\ Score = 8 + x$

Required

Set up an equation

Solve for the fifth and sixth score

Average is calculated as thus:

$Average = \frac{\sum x}{n}$

$Average = \frac{83 +78 + 87 + 80 + x + 8 + x}{6}$

Substitute 85 for Average

$85 = \frac{83 +78 + 87 + 80 + x + 8 + x}{6}$

$85 = \frac{83 +78 + 87 + 80 + 8+ x + x}{6}$

$85 = \frac{336+ 2x}{6}$

Multiply both sides by 6

$85 * 6 = 336 + 2x$

$510= 336 + 2x$

Solve for 2x

$2x = 510 - 336$

$2x = 174$

Solve for x

$x = 174/2$

$x = 87$

Hence:

$Fifth\ Score = 87$

$Sixth\ Score = 87 + 8$

$Sixth\ Score = 95$

How do you simplify this equation?

faust18 [17]

Answer:

The answer is B --> $\frac{x^{2} }{3x^{2} -1}$

How I got that:

These are really easy, you're simply looking for numbers that you can factor down. Like here:

I took:

$\frac{4x^{2} }{12x^{2} -4}$

and saw that I could factor out 4 from the denominator:

$\frac{4x^{2} }{4(3x^{2} -1)}$

and then I canceled out the common factor (4 because its on both sides):

$\frac{x^{2} }{3x^{2} -1}$

And there ya go!
