The Y intercept is approx 4. The Y intercept represents the number of matches won. I do not know Part B: (

A.
y-intercept is where the line crosses the y axis
it seems to cross at y=4

B. seems to be linear, so
y=mx+b is equation
m=slope
b=y intercept
we know that yintercept=4=b

slope=rise/run=z/t
it for every z units it goes up, it goes to the right t units
seems to go up 17 for every 11 units it goes to the right
so slope=17/11

equation is $y=\frac{17}{11}x+4$
so predict that after 13 months (x=13), we have y=(17/11)13+4=221/11+4≈24 games won

I need help with this question (Trigonometry)

Solnce55 [7]

A)2.8
b1) 4.5/2.8
b2)impossible because if you want to do trigonometry you can't have that is an angle (Which is 148.1) larger than 90 degrees.
but if its angle BAF then the angle would be 2.8/5.3
c)41.32

Question 1

kenny6666 [7]

The inequality is given by 20x + 25y ≤ 1100 and x + y > 50

<h3>What is an inequality?</h3>

An inequality is an expression that shows the non equal comparison of two or more numbers and variables.

Let y represent the number of soccer balls and x represent the number of volleyballs.

The coach can spend a maximum of $1,100, hence:

20x + 25y ≤ 1100

Also, The coach plans to order at least 50, hence:

x + y > 50
