<span>Complete the slope-intercept form equation of the line with slope − 8 that passes through the point (0,−2) (don't mention (0,-2) more than once)
y = mx + b, with m= -8, comes out to y = -8x + b.
Subst. 0 for x and -2 for y and then calculate b: -2 = 0 + b => b = -2
Then the equation is y = -8x - 2.</span>
They sell 18 costumes per day, times 5 days.
So,
18 costumes per day * 5 days
18*5 =90
These are vertical angles so they are equal.
3x + 50 = 6x - 10
50 + 10 = 6x - 3x
3x = 60
x = 20 answer
Answer:
Step-by-step explanation:
Sarah is selling bracelets. The inequalities are a > 10 and 2a + 3b ≥ 60.
<u>Solution:</u>
Given, Sarah is selling bracelets and earrings to make money for summer vacation.
bracelets cost = $2
earrings cost = $3
She needs to make at least $60.
Sarah knows she will sell more than 10 bracelets.
We have to write inequalities
Now, according to given information,
Total money ≥ $ 60
Money earned from bracelets + money earned by earrings ≥ 60
2 x number of bracelets + 3 x number of earrings ≥ 60
2a + 3b ≥ 60
[ where a is number of bracelets and b is number of earrings]
And, number of bracelets is more than 10 ⇒ a > 10
Hence, the inequalities are a > 10 and 2a + 3b ≥ 60
