Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (2, 4) ← 2 points on the line
m = 
=
Area=1/2bh
add them
(1/2)ab+(1/2)c^2+(1/2)ab=
ab+(1/2)c^2
ab+(1/2)(a^2+b^2)
not sure which option to pick there are different preferences on what counts as 'simplified'
4. find area
area=LW
area=105*45=4725
depends on the area of the signs
answer is
4725/(areaof1sign)
anyway, round down your answer because you will have an incomplete sign if you don't
5. area=pir^2
1/2 of it is
area=1/2pir^2
area=(1/4)^2pir^2
area=pi((1/4)r)^2
the radius is now 1/4 of what it was originally, meaning that the diameter is also 1/4 of what it is now
we need to know diamater
answer is 1/4 of current diameter
3. unclear
4. area of 1 sign not given, answer is 4725/(areaof1sign), rounded DOWN to nearest integer
5. (404 error, diameter not found) answer is 1/4 of current diameter
Answer:
21,800
Step-by-step explanation:
I'm assuming you meant 2.18 x 10^4
Since the exponent is positive, you will move the decimal point 4 spaces to the right.
Answer:
(2,9)
Step-by-step explanation:
To do this you have to solve one of the equations for a variable.
-x+y=7
2x+3y=31
Because the first equation doesn't have any numbers attached to the variables I decided to solve for the y in that equation.
-x+y=7
y=x+7
With this now one would have to plug this into the second equations:
2x+3(x+7)=31
Use the distributive property.
2x+3x+21=31
simplify.
5x+21=31
Isolate the x.
-21 -21
5x=10
solve for the x.
x=2
Plug the x into one of the equations and solve for y.
-x+y=7
-2+y=7
isolate the y.
+2 +2
y=9
This is the point of solution.
