Answer:
look up answer key realy would help
Step-by-step explanation:
Cos(x)= adjacent/hypotenuse
cos(18)=x/25 (cross multiply)
25*cos(18)=x
x= 23.78 cm <--- this is rounded to the nearest hundredth.
Answer:
y = 2x+8
Step-by-Step Explanation:
The equation should be in the form of y=mx+b
So you already know it's not A. Also you already know it's not D because the line goes at an angle, if "m"(slope) was 0 then the line would be straight horizontal or straight vertical. So that leaves B and C. And finally you know it's not B because the line is going in the positive direction not negative, so the slope has to be positive, also "b" in the equation is the y-intercept, and that's where the line intersects with the y-axis, and you can see that the line intersects at 8 on the graph. Therefore, the answer is C, y=2x+8
Hope this helps!! :)
If your equation is 2v + 7 = 3,
Subtract 7 from both sides to get 2v = -4
Then divide 2 on both sides and get v = -4/2
Then simplify to get v = $-2
Answer:
$20
Step-by-step explanation:
25 x (20/100) = 5
25 - 5 = 20
