Answer:
D
Step-by-step explanation:
General Equation: y = mx + b
You need two pieces of data to solve this.
When x = 1, y = 8
8 = 1x + b
When x = -1, y = 3
3 = - x + b
==================
8 = x + b
3 = -x + b If we add we get b so let's add.
11 =2b Divide by 2
11/2 = b
==================
y = mx + b
y = mx + 11/2 Now we can solve for m
3 = -m + 11/2 Subtract 11/2
3 - 11/2 = - m
- 2 1/2 = -m multiply by - 1
2 1/2 = m
m = 5/2
The answer is D
Answer:
Jamal hiked = 44/3 miles
Step-by-step explanation:
Mixed numbers are given in this question which can be changed into fractions by multiplying the denominator by quotient and adding numerator to it.
Given that:
Length of first trail: 5 1/3 = (3*5 + 1)/3 = 16/3 miles
According to given condition:
Length of second trail: 1 3/4 * 16/3 = (4*1+3)/4 * 16/3 = 7/4*16/3
By simplifying:
Length of second trail = 28/3 miles
So the total miles Jamal hiked = 16/3 + 28/3
Jamal hiked = 44/3 miles
i hope it will help you!
If the angles of the triangle are 50, 90, 40 degrees, then only 1 triangle can be made. Because if you change the sides, the angles would change
:)
Notice that both equation has a 2f term in them
solve for 2f for both eqs.
2f= 736-6n
2f= 920-10n
since they both equal to 2f, yo can set them equal to each other
736-6n = 920-10n
and solve for n if you want
