8 0

Step-by-step explanation:

a. (0.60x + 0.70y)- 50 = 10

<=> 0.60x + 0.70y = 60

b. (x+y) = 5(x-y)

x+y=5x-5y

<=> 4x - 6y = 0

Find the equation of the line that pass through the points (4,8) and (6,2

jeyben [28]

Answer:

3x + y = 20

Step-by-step explanation:

The equation of line passing through two points is determined by formula:

$y-y_{1}=\frac{y_{2}-y_{1}}{x_{2} - x_{1}}(x - x_{1})$

Here, (x₁ , y₁) = (4, 8)

and (x₂, y₂) = (6, 2)

Putting these value in above formula. We get,

$y-8=\frac{2-8}{6 - 4}(x - 4)$

⇒ $y-8=\frac{-6}{2}(x - 4)$

⇒ ( y - 8) = -3 (x - 4)

⇒ y - 8 = -3x + 12

⇒ 3x + y = 20

which is required equation.

If h(x)=x-7 and g(x)= x^2, which expression is equivalent to (goh)(5)

Finger [1]

Answer:

(goh)(5) = 4

Step-by-step explanation:

(goh)(x) = g(x-7)

g(x-7) = (x-7)^2

g(x-7)= x^2 - 14x + 49

(goh) = x^2 - 14x + 49

(goh)(5) = 5^2 - 14(5) + 49

(goh)(5) = 25 - 70 + 49

(goh)(5) = 4
