Answer: distance from earth to moon is 4x10^5= 4,000,000
The distance from Earth to Mars is about 5x10^7= 50,000,000.
Step-by-step explanation:
Part A: Explain why the x-coordinates of the points where the graphs of
the equations y = 4-x and y = 2x + 3 intersect are the solutions of the
equation
4-x = 2x + 3.
Because the point where the graphs intersect is a point that meets both rules (functions) y = 4 - x and y = 2x + 3 meaning that y from y = 4 - x equals y from 2x + 3 and also both x have the same value.
Part B: Make tables to find the solution to 4-x = 2x + 3. Take the integer values of x between -3 and 3.
x values 4 -x 2x + 3
-3 4-(-3)=7 2(-3)+3 =-3
-2 4-(-2)=6 2(-2)+3 =-1
-1 4-(-1)=5 2(-1)+3 = 1
0 4-0=4 2(0)+3 = 3
1 4-1=3 2(1)+3=5
2 4-2=2 2(2)+3 = 7
3 4-3=1 2(3)+3 = 9
The the solution is between x = 0 and x =1
Part C: How can you solve the equation 4-x = 2x + 3 graphically?
Draw in a same graph both functions y= 4 - x and y = 2x +3.
Then read the x-coordinates of the intersection point. That is the solution.
There is a square and a triangle
the area of a square is
A = b * h
A = 2*2
A = 4
the area of the triangle is
A = (b*h)/2
A = (2 *2)/2
A = 4/2
A = 2
Now we add them up to find the total area
4 + 2 = 6
The shape has an area of 6 units^2
Answer:
the answer i got was 1159.1
Step-by-step explanation:
cos75 = 300/x
0.25881905 = 300/x
multiply everything by x
0.25881905x = 300
Divide everything by 0.25881905
x = 1159.1
is that close to any of your answers?
I believe D. 180. I am sorry if I am wrong though
