Which proportion can be used to show that the slope of AC Is equal to the slope of DF? A 6-(-3) -7-(-3) = -3-(-9) 5-13 B. 6-3 -7-(-3) -3-(-9) 5-13 C. 6-(-3) -7-3 -3-9 5-13 D. 6-3 -7-3 -3-9 5-13

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

it is x=-4

step-by-step explanation:

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

answer: c

(2, -4)

goes 7 to the

(9, 4)
