Point slope means
y-y1=m(x-x1)
where the slope is m and a point on the graph is (x1,y1)
we are given
slope=-3
therefor
y-y1=-3(x-x1)
eliminate choices A and D
they gave us point (5,-7)
x1=5
y1=-7
y-(-7)=-3(x-5)
y+7=-3(x-5)
C is answer
AB+AT=BT
(7Y+9)+(3Y+4)= 143
10Y+13= 143
10Y= 130
Y=13
AB= 7Y+9
AB= 7*13+9
AB=100
Answer:
an expression is the one with out the equal sign.
Step-by-step explanation:
Answer:
15 q4. + 7p2q2 is the correct answer
15/124 is 1860 multiply
230/30 is 6900 multiply
