Answer:
C. 22 cm, 8 cm, 27 cm
Step-by-step explanation:
In order to make a triangle with given side lengths, sum of any two side lengths must always be greater than the third side.
here,
22 + 8 = 30 > 27
8 + 27 = 35 > 22
27 + 22 = 49 > 8
Hence, C. 22 cm, 8 cm, 27 cm is the correct option.
Answer:
3 friends played golf
Step-by-step explanation:
33-12=21
21/7=3
A- 4/6, B- 3/6
If both events happen, the probability is A*B= 4/6 * 3/6 = 12/36= 1/3
P(AnB)= 1/3
Answer:
2. y = -1/2x - 1
Step-by-step explanation:
First we want to find the slope of the line.
To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values using two points (-4, 1) & (2, -2)
(-2 - 1) / (2 - (-4))
Simplify the parentheses.
= (-2 - 1) / (2 + 4)
= (-3) / (6)
Simplify the fraction.
-3/6
= -1/2
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = -1/2x + b
b is the y-intercept when the line crosses the y-axis.
From the graph, we can see that the point on the y-axis is (0, -1)
Therefore, b is -1.
Plug this into the equation.
y = -1/2x - 1
Hope this helps!
