Answer:
Step-by-step explanation:
If the value of y is same for both then we have equal right sides of equations
Solve this for x
- 50x - 30x = 70 - 10
- 20x = 60
- x = 60/20
- x = 3
Find the value of y
- y = 50*3 + 10 = 150 + 10 = 160
Correct choice is A
8:5:3 this is the simplest ratio
The only of these that is a proper set of ordered pairs for this equations is A) (0,-4) (1,2) (3,14)
In order to prove this, you need to put each ordered pair into the equation and prove that it is a true statement. Below are the examples of this for A.
(0, -4)
y = 6x - 4
-4 = 6(0) - 4
-4 = 0 - 4
-4 = -4 (TRUE)
(1, 2)
y = 6x - 4
2 = 6(1) - 4
2 = 6 - 4
2 = 2 (TRUE)
(3, 14)
y = 6x - 4
14 = 6(3) - 4
14 = 18 - 4
14 = 14 (TRUE)
Therefore, each of these ordered pairs works in the equation.
Answer:
D. 65°
Step-by-step explanation:
The measure of the angle at crossed chords is the average of the measures of the intercepted arcs:
m∠XYZ = (1/2)(arc XZ +arc WV)
m∠XYZ = (1/2)(86° +44°) = 130°/2
m∠XYZ = 65°
Answer:
Slope = 5/2
Step-by-step explanation:
The equation of the line
y = mx + c
y = intercept point y
m = slope of the line
x = intercept point x x
c = intercept
Given
Points ( 6 , 8) ( 4 , 3)
x1 = 6
y1 = 8
x2 = 4
y2 = 3
Insert the values
m = y2 - y1 / x2 - x1
m = 3 - 8 / 4 - 6
= -5/-2
Minus cancel minus
= 5/2
The slope of the line is 5/2
