Answer:
y=-8
Step-by-step explanation:
From the information given, we know that the slope of the line is 0. Let's make an equation in y=mx+b form with what we know.
y=0x+b
We also have a point on the line, (5, -8). We can plug these two numbers for x and y to find b and complete the equation. -8 goes in as y and 5 goes in as x.
-8=0(5)+b
Now just solve for b.
-8=0+b
b=-8
We now know that b is -8 and can complete the equation.
y=0x-8
y=-8
The number is 6
4x-9=15
4x=24
X=6
20 / 4 = 5 miles per hour
5 x 10 = 50 mile in all 10 hours
Fred can hike 50 miles in 10 hours total
Answer:
x = 30
Step-by-step explanation:
The two angles add to a right angle which is 90 degrees
30 +2x = 90
Subtract 30 from each side
30 +2x - 30 =90-30
2x= 60
Divide each side by 2
2x/2 = 60/2
x = 30
