The ordered pair (7, 19) is only a solution to the first equation, 14-19= -5. the ordered pair is not a solution to the second equation 7 + 57 does not equal 22.
Answer:
The area of the triangle is 28 square units
Step-by-step explanation:
First we have to calculate the length of the base of the triangle and the length of the height
To calculate the base we have to subtract point (-1 , 2) from point (7 , 2)
(7 , 2) - (-1 , 2) = ((7 - (-1)) , (2 - 2)) = (8 , 0)
because it has no component in y this means that the length of the base is 8
b = 8
To calculate the height we have to subtract point (-1 , 2) from point (-1 , 9)
(-1 , 9) - (-1 , 2) = (((-1) - (-1)) , (9 - 2)) = (0 , 7)
because it has no component in x this means that the length of the base is 7
h = 7
To calculate the area of a triangle we have to multiply the base by the height and then divide it by 2
a = (b * h)/2
a = (8 * 7)/2
a = 56/2
a = 28
The area of the triangle is 28 square units
Answer:
ok sure lol

Answer:
C.12
Step-by-step explanation:
Apply the formula for tangent-secant
Let the cord length inside the circle to be y
According to the tangent-secant relation
(3+y)/6 = 6/3
cross multiply
3(3+y)=6*6
9+3y=36
3y=36-9
3y=27
y=27/3
y=9
Distance x = y+3
x=9+3=12
