-x-y=-5
-x+y=1
adding up the equations gives;
-2x=-4
x=2
replacing in the first equation;
-2-y=-5
-2+5=y
y=3
They would intersect at (2,3)
Answer:
m<DBE =50°
m<ABD=150°
Step-by-step explanation:
Because of Straight Angles, All the angles will add up to 180 degrees
Let x be m<DBE
40+x+70+20=180
x+130=180
x=50
m<DBE will be 50 degrees
To find the m<ABD, we add m<FBA, m<FBE, m<DBE.
70+50+30=150
m<ABD = 150
Answer:
0.25feet
Step-by-step explanation:
The equation is not well written. Let the equation of the height be modelled as;
h = -16d²+8d+4
The velocity of the ball is zero at its maximum height.
Velocity = change in displacement/time
v = dh/dd
Differentiate
v = -32d+8
Since dh/dd = v = 0
0 = -32d+8
Add 32d to both sides
0+32d = 8
32d = 8
Divide both sides by 32
32d/32 = 8/32
d = 1/4
d = 0.25feet
Hence the maximum height of the tennis ball is 0.25feet
Note that the modeled equation was assumed. You can apply the same calculation to any equation given
