Answer:
x = 40 , y = 70
Step-by-step explanation:
y = 70°
x° = 180° - 2 × 70° = 40°
I think it’s A sorry if I’m wrong
Answer:
768,543, and 8,451
Step-by-step explanation:
The 8 is in the hundreds place, so when multiplied by 10 it would be in the thousands place.
Answer:
Correct choice is C). mn=ac
Step-by-step explanation:
Given statement is that the first step in factoring a trinomial of the form is to find two numbers, m and n, such that m + n = b and _____.
We know that when we factor polynomial of type
,product of both numbers m and n must be same as product of a and c.
Hence correct choice is C). mn=ac
Finding gradient:
m = y2 - y1
x2 - x1
= -1 - 6
1 - 3
= -7 / (-2)
= 7/2
y = m(x - x1) + y1
y = 7(x - 3) + 6
2
2y = 7x - 21 + 12
2y = 7x - 9
