Answer: It's probably 4.
Step-by-step explanation:
7-3=4
Answer:
4 hits in the second game
Step-by-step explanation:
If he hit 3 in the first game and 7 total, then the remainder (7-3) would be 4 for the second game,
12x−5y=−20
y=x+4
Answer:
12x-5(x+4)=-20
7x=0
x=0
so,y=4
−2/3
−3/2
−1/2
3x + 2y + 1 = 0
subtract 3x+1 from each side
3x + 2y + 1 - 3x -1= -3x -1
2y = -3x-1
divide by 2 on each side
2y/2 = -3x/2 -1/2
y = -3/2 x -1/2
this is in the form y = mx +b where m is the slope
m = -3/2
the slope is -3/2
solve system by substitution y=3x-20 y=-x^(2)+34

Answer:
CD = 10
AD = 22
EC = 13
AC = 26
∠CAD = 23°
∠BAC = 47°
∠ADC =110°
Step-by-step explanation:
A parallelogram is a quadrilateral with two sets of opposite parallel lines.
Which mean in ABCD parallelogram given AB is parallel to DC and BC is parallel to AD.
Now lets find the values required,
CD = AB (Opposite sides are equal in length)
But, AB= 10 (given) therefore CD = 10.
AD = BC (Opposite sides are equal in length)
But, BC= 22 (given) therefore AD = 22.
EC = AE (Diagonals bisect each other)
But, AE= 13 (given) therefore EC = 13
AC = AE + EC
=
AC =
∠CAD = ∠BCA (Alternate interior angles are equal)
But, ∠BCA = 23° therefore, ∠CAD = 23°
∠BAC = ∠ACD (Alternate interior angles are equal)
But, ∠ACD = 47° therefore, ∠BAC = 47°
∠ADC + ∠BCD = 180° (Consecutive interior angles)
But, ∠BCD = 23°+47°=70°
∠ADC = 180°- ∠BCD
=180°-70°
∠ADC =110°
Answer:
A = 62.5
Step-by-step explanation:
I would break this up into two easier cases. the square at the top where three vertices are A,B, and C. and then the triangle for the rest of the area. we can use the distance formula to find the side length of the square.
sqrt((y2-y1)^2 + (x2-x1)^2)
sqrt((5-2)^2 + (-1-3)^2)
sqrt(3^2 + (-4)^2)
sqrt(9 + 16)
sqrt ( 25)
5
so the area of the square is 5^2 =25
now for the triangle. the formula for the area of a triangle is (1/2)bh.
so we can plug in our b=5, but we need to find h.
we use the distance formula between point A and D to find the distance to be 20, but we have to subtract the 5 we already counted in the area of the square. so the height is 15.
so The triangle has area (1/2)×5×15
37.5.
add the two areas together and we get our answer
25+37.5 = 62.5
