Answer:
3
Step-by-step explanation:
(x₁ , y₁) = (-1 , -2) & (x₂ , y₂) = (3 , 10)

![= \frac{10-[-2]}{3-[-1]}\\\\=\frac{10+2}{3+1}\\\\=\frac{12}{4}\\\\=4](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B10-%5B-2%5D%7D%7B3-%5B-1%5D%7D%5C%5C%5C%5C%3D%5Cfrac%7B10%2B2%7D%7B3%2B1%7D%5C%5C%5C%5C%3D%5Cfrac%7B12%7D%7B4%7D%5C%5C%5C%5C%3D4)
m = 4
y - y₁ = m (x - x₁)
y - [-2] = 4(x - [-1])
y + 2 = 4(x + 1)
y + 2 = 4x + 4
y = 4x + 4 - 2
y = 4x + 2
If you would do this in whole number form, it'll be 40/7.
Answer:
C, 12
Step-by-step explanation:
least common multiple of 4 and 6 is:
prime factorization of 4: 2*2
prime factorization of 6: 3*2
common factors: 2, so you should only multiply one of the common 2s when multiplying the factors to get the least common multiple
2*2*3=12
12 is a common denominator of 1/4 and 5/6
Answer:

Step-by-step explanation:
we are given a trapezoid
we want to figure out the area
remember that,

where a and b represent the parallel lines and h represents the height
we get from the pic that a and b are 5 and 15 respectively and h is 7
so substitute:

simplify addition:

simplify division:

simplify multiplication:

since we multiply two same units we of course have to use square unit
hence,

Use a variable to represent the number of hours the technician will work, plus the $50.
50+25x
This would be the expression used to find the amount of money the technician needs.
