Answer:
-3x + 5.
Step-by-step explanation:
(f + g)(x) = x + 8 - 4x - 3
= -3x + 5.
Answer: 0.75
Step-by-step explanation:
We can do this by drawing a terminal side in a standard position and then drawing the associated triangle. We then use the Pythagoras theorem to find the missing side the hypotenuse. Then, this will give a Pythagorean Triplet of 3, 4 and 5.
We now have a triangle with the values of:
x = 4
y =3
h^2= 4^2 + 3^2
h^2 = 16 + 9
h^2 = 25
h = 5
h = 5
Tangent = opposite/adjacent
= y/x
= 3/4
= 0.75
To find 10per cent just divide by 10, the answer is 8
Answer:
y=1/2x+3
Step-by-step explanation:
-4x+8y=24
Slope-intercept form: y=mx+b
Add -4x on each side
-4x+8y=24
+4x +4x
8y=4x+24
Divide by 8 on each side
<u>8y</u>=<u>4x+24</u>
8 8
y=4/8x + 3
Simplify 4/8x
y=1/2x+3
