A line passes through the points (−3,1) and (1,−2). This line can be modeled by the equation y=ax+b. What are the values (in fra
victus00 [196]

Answer:

see explanation

Step-by-step explanation:

y = ax + b is the equation in slope- intercept form

where a is the slope of the line and b is the y- intercept

To find a use the slope formula

a = (y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 1) and (x₂, y₂ ) = (1, - 2)

a = \frac{-2-1}{1+3} = - \frac{3}{4} = - 0.75, hence

y = - 0.75 + b

To find b substitute either of the 2 points into the equation

using (1, - 2), then

- 2 = - 0.75 + b ⇒ b = - 2 + 0.75 = - 1.25 = - 1 \frac{1}{4}

2. Given h(x) = x2 +11 and g(x) = √ x-2 evaluate : (h ∘ g) (38)
slavikrds [6]

Step-by-step explanation:

By the definition of composition we have that h(g(x))=h(5x-2)=(5x-2)^2+11=25x^2+4-20x+11=25x^2-20x+15.

PLEASE HELP!
kiruha [24]

Answer:

A) The second day

B) 9/16 inches

A) Elsa reached farther on the second day because -1/16 > -5/8

B) To calculate this we must first put both fractions above the same denominator. We can then subtract the smaller one from the bigger one:

-1/16 - (-10/16) = 9/16

Elsa reached 9/16 inches farther on the second day then she did on the first.

Hope this helps and have a great day!

Also stay safe! :))))
