Answer:
The slope <em>m</em> is 1.9 and the y-intercept <em>b</em> is 2.5.
Step-by-step explanation:
This is in slope-intercept form, y=<em>m</em>x+<em>b</em>, where <em>m</em> is slope and <em>b</em> is the y-intercept.
y = 1.9x + 2.5 means that <em>m </em>is 1.9 and <em>b</em> is 2.5.
Answer:
The slope of the line is: 3
Step-by-step explanation:
Given the points
(-3, -6) and (3, 12)
Determine the slope between (-3, -6) and (3, 12) using the formula

where
m is the slope between (x₁, y₁) and (x₂, y₂)
In our case,
now substitute (x₁, y₁) = (-3, -6) and (x₂, y₂) = (3, 12) in the slope formula





Therefore, the slope of the line is: 3
Answer:
5.43×10^14 or

Step-by-step explanation:
Scientific notation, the number must always be less than 10, in this case 5.43. The exponent represents how much times I moved the decimal point to the left.
11. 2x+3x+1=21
5x+1 =21
5x=20
x=4
TU= 2(4) which is 8
UB= 3(4)+1 which is 13
12. 4x-1 +2x-1=5x
6x-2=5x
-2=-1x
2=x
X=2
TU= 7
UB= 3
TB=10
Problem 13:
2x-8=x+17
2x=x+25
x=25
AB =42
BC=42
AC=84
Problem 14:
3x-31
-x+6
=
2x-37 for BC part now we solve for x
x+6=2x-37
6=x-37
43=x
So :
X=43
AB=49
AC=98
BC=49
Answer:
186 mph
Step-by-step explanation:
Miles per hour means miles divided by hour(s), so 558/3 is 186 miles per hour.
