Answer:
x = 3.86
a = 5.86
Step-by-step explanation:
From the triangles attached,
By applying cosine rule in triangle 1,
cos(50)° = 
cos(50)° = 
x = 6cos(50)°
x = 3.86
Now we apply sine rule in the second triangle,
sin(23)° = 
sin(23)° = 
a = 15sin(23)°
a = 5.86
It's increasing cause it's going higher if it's decreasing it's going lower
F(x)=y=2x+3
P (1,5)
Substitute x and y:
5=2*(1)+3
5=5 true
Point P (1,5) is on the graph of f.
Answer:
y = 3/8x +29/8
Step-by-step explanation:
First we need to find the slope
m= (y2-y1)/(x2-x1)
= (1-4)/(-7-1)
= -3 /-8
= 3/8
Then we can use the slope intercept form of the equation of a line
y = mx+b where m is the slope and b is the y intercept
y = 3/8x +b
Substitute a point into the equation to find b
4 = 3/8(1) +b
Subtract 3/8 from each side
32/8 -3/8 = 3/8-3/8+b
29/8 = b
Substitute b back into the equation
y = 3/8x +29/8
