Complete the equation of the linear function.

1 answer:

5 0

The two points we are given will tell us the slope of the line, and the first point even tells us the y intercept.

slope = (y2 - y1) / (x2 - x1) = (1 - 4) / (1 - 0) = -3/1 = -3

Since the function goes through (0,4), our y intercept is 4.

Now we can fill in our function:
y = _ x + _
y = -3x + 4

How do exponets allow u to communicate more Prescisey to others

Vikentia [17]

Exponents allow for shorter, more concise answers. Say you needed to state the number 88,209. 9^5 is a much shorter number, and still gets the point across.

solve for x in the rhombus sin(42)= x/50

Hunter-Best [27]

Answer:

x = 33.45

Step-by-step explanation:

We need to find the value of x in the given expression i.e.

$\sin(42)=\dfrac{x}{50}$

Multiplying both sides by 50. So

$\sin(42)\times 50=\dfrac{x}{50}\times 50\\\\x=\sin(42)\times 50\\\\x=33.45$

So, the value of x is equal to 33.45.
