Answer:
-1.25
Step-by-step explanation:
(3,8) (7,3)
(8-3)/(3-7)= 5/-4= -1.23

Answer:
x intercept=2
y intercept=6
Step-by-step explanation:
to find x and y intercepts, plug in 0 for x and y
x intercept-
6x+2(0)=12
6x=12
x=2
y intercept-
6(0)+2y=12
2y=12
y=6
Answer:
C) 4.01
Step-by-step explanation:
When rounding to 2dp, you look at the third digit after the decimal. If it is 5 or larger, you round the second digit up, if it is less than 5, you round it down.
Answer:
7
Step-by-step explanation:
Use secant-tangent product theorem.
1. Set up the equation
(x-3)(x-3+5) = (x-1)²
2. Solve
(x-3)(x+2) = (x²-2x+1)
(x²-x-6) = (x²-2x+1)
3. Solve for x
Subtract x² from both sides
-x-6 = -2x+1
Add 2x and 6 to both sides
x = 7
Answer:
4 1/4
Step-by-step explanation:
the additive inverse is a number that when you add it with the number you already had, makes 0
-2 is the additive inverse of 2
so 4 1/4 is the inverse of -4 1/4
