In a video game, Agnes scored 20% fewer than Amy. Amy scored 860

vovangra [49]

Answer:

$\huge\boxed{\sf Agnes\ Score = 688\ points}$

Step-by-step explanation:

$\sf = 20 \% \ of \ 860 \\\\= \frac{20}{100} * 860\\\\= 2 * 86\\\\= 172 \ points$

Since, Agnes scored 20 % fever than Amy.

So,

Agnes Score = Amy's Points - 20 % of Amy's Points

Agnes Score = 860 - 172

Agnes Score = 688 points

$\rule[225]{225}{2}$

Hope this helped!

How do you convert set notation to interval notation?

Semenov [28]

Answer:

Imagine we are to express [ a , b ] in set notation

A = [ a , b ] , then A = { x ∈ R / a ≤ x ≤ b }

In this notation we define the characteristics of all x belonging to this set A ....x must be greater or equal to a and simultaneously smaller or equal to b...

Interval notation is other way to say the same but assuming that means the extreme a is IN the interval and means extreme a is not.

14. The equation of the line that passes through the

KIM [24]

Answer:

5. y = -x

Step-by-step explanation:

First, you need to find the slope of the line.

$m = \frac{2 - (-3)}{-2 - 3} = \frac{5}{-5} = -1$

Now, using either point substitute into the point-slope form for a line:

$y - y_{1} = m(x - x_{1} )$

Using (-2,2) for $(x_{1} , y_{1} )$ we get y - 2 = -1(x +2)

y - 2 = -x - 2

y = -x

Answer 5 is the correct answer
