Answer:
(3, -8) and (2, -10)
Step-by-step explanation:
Given
Required
Select the true coordinate points in (3, -8) (2, 5) (-5, 1) (10, 3) (2, -10)
(3, -8)
x = 3 and y = -8
--- True
--- True
(2, 5)
x = 2 and y = 5
--- False (No need to check the other inequality)
(-5, 1)
x = -5 and y = 1
--- True
--- False
(10, 3)
x = 10 and y = 3
--- False (No need to check the other inequality)
(2, -10)
x = 2 and y = -10
--- True
--- True
Hence, the solution to the inequalities are:
(3, -8) and (2, -10)
First you need to simplify the left side of the equation to get
Then you add by two on both sides to get
Finally you divide by 2 on both sides to get
First, do what's in the paranthesis:
(4*4-12)
Multiplication first:
16-12
Then subtract:
4
We get:
5-1+2*4*8
Multiply:
2*4
8
Multiply, again:
8*8
64
We get:
5-1+64
Subtract:
5-1
4
Add:
4+64
Answer: 68
Answer:
y = 2x - 1
Step-by-step explanation:
Slope
for every increase of 3 in x
there's an increase of 6 in y
m = rise/run
m = 6/3
m = 2
----------------------------
Slope intercept form is
y = mx + b
To find "b" plug in m = 2 and any of the given points
using (1, 1)
1 = 2(1) + b
1 = 2 + b
b = -1
The equation is
y = 2x - 1
1 millimetre = 1/1000 = 1×10^-3 m
