Answer:
(cx)2-(dy) 2
Step-by-step explanation:
Formula a2-b2= (a+b) (a-b)
By given formula
(cx)2 - (dy) 2 = (cx+dy) (cx-dy)
Answer:
- b. 25.7 + 13.2 + 6.4 = 45.3
Step-by-step explanation:
25.65 ≈ 25.7, 13.23 ≈ 13.2, 6.35 ≈ 6.4
- 25.65 + 13.23 + 6.35 =
- 25.7 + 13.2 + 6.4 =
- 45.3
Correct choice is b.
Answer:
y= -3/4x - 3
Step-by-step explanation:
-3/4 is the slope, so you replace m with the slope.
The y intercept is -3. If x is 4, and y is -6, we can plug that into an equation to find the y intercept. y=mx+b can change to -6= -3/4 * 4 + b. B = -3.
(0,6)(4,3)
slope = (3 - 6) / (4 - 0) = -3/4
ur y int (where the line crosses the y axis) is (0,6)
in y = mx + b form, the slope will be in the m position and the y int will be in the b position.
Therefore, ur equation is : y = -3/4x + 6 <==
