Answer:
y ≈ 5.2
Step-by-step explanation:
∠ F = 180° - (42 + 48)° ← sum of angles in a triangle
∠ F = 180° - 90° = 90°
Thus Δ DEF is right at F
Using the sine ratio in the right triangle
sin48° = 
= 
= 
( multiply both sides by 7 )
7 × sin48° = y , then
y ≈ 5.2 ( to the nearest tenth )
Answer:
6 is 100 times 0.06
Step-by-step explanation:
0.06 times 100 = 6
Y=-10 and the second one is 13 I think
Answer:
= -x^2 -x +6
D: all real values
Step-by-step explanation:
f(x) = 4-x^2
g(x) = 2-x
f+g = 4-x^2+ 2-x
Combine like terms
= -x^2 -x +4+2
= -x^2 -x +6
The domain is what values can x take
D: all real values
Answer:
y=-3.5x+9
Step-by-step explanation:
the slope is determined by the y1-y2/x2-x1 which is equaled to -5-2/4-2 which is equaled to -7/2 which is -3 1/2 which is your m value in y=mx+b and you graph to get your b value (y-intercept) which is 9
