X-intercept ⇒ When y = 0

(x – 3)² + (y – 4)²<span> = 24

When y = 0,
</span>(x – 3)² + (0 – 4)² = 24

(x – 3)² + 16 = 24

(x – 3)² = 8

(x - 3) = ±√8

x = √8 + 3 or x = -√8 + 3 

x = (3 + 2√2) or (3- 2√2)        [Radical Form]

x = 5.83 or 0.17                     [Decimal Form]

Answer: (5.83, 0) and (0.17, 0)

2x-14+2y=24
2x=24+14-2y
2x=38-2y
x=19-y

A school bought pens, each costing $1, and pencils, each costing $0.5. The cost of the whole purchase was $220. How many pens an
Aleks [24]

Answer:

<u>The number of pens = 120 and the number of pencils = 200</u>

Step-by-step explanation:

Let the number of pens x, and the number of pencils is y

the cost of one pen $1, and the cost of one pencil $0.5

The cost of the whole purchase was $220

1 * x + 0.5 * y = 220

x + 0.5 y = 220 ⇒ eq.(1)

there were 80 more pencils than pens

y - x = 80 ⇒ eq.(2)

from eq.(2) x = y - 80

By substitution with x from the last equation at eq.(1)

∴ (y - 80) + 0.5 y = 220

1.5y = 220 + 80 = 300

y = 300/1.5 = 200

x = y - 80 = 200 - 80 = 120

<u>So, the number of pens = 120 and the number of pencils = 200</u>

What is 0.3636363636 to the nearest thousandth?
Bad White [126]

Answer: 0.364

The reason that it would be 0.364 is because the thousandths place is the third decimal place, which would leave you with a 3 but since there is a 6 after the 3, the 3 would be rounded up to a 4.

If Ashley is in the 85th percentile and the mean of her test scores is 180 with a standard deviation of 15, which of the followi
ioda
<span>B would be the most appropriate response for this. We don't need to worry about Ashley being in the 85th percentile, that is just extra information they have provided us. What we need to look at is her mean test score is 180, so that is the average score she normally gets on her tests, but then they say she has a standard deviation of 15 which means her scores are normally no lower than 165 and no higher than 195 because she normally doesn't deviate or change her score more than 15 points for her normal 180. So if you take 180 minus 15 you get 165 and if you take 180 plus 15 you get 195, therefore we can determine that the most appropriate answer would be between 165 and 195. The only option that fits in this category is B 185</span>
