Answer:
x=−48.541019
Step-by-step explanation:
4+√5x+66=x+10
Simplifies to:
2.236068x+70=x+10
Let's solve your equation step-by-step.
2.236068x+70=x+10
Step 1: Subtract x from both sides.
2.236068x+70−x=x+10−x
1.236068x+70=10
Step 2: Subtract 70 from both sides.
1.236068x+70−70=10−70
1.236068x=−60
Step 3: Divide both sides by 1.236068.
1.236068x
1.236068
=
−60
1.236068
x=−48.541019
Answer:
Step-by-step explanation:
A standard form equation is when it is set up
Ax + By = C.
6x + 2y = 4
A slope-intercept form equation is when it is set up y=mx+b.
Y = - 3x + 2
In order to go from one form to another, all you have to do is change the order of the given numbers. First you want to move the Ax to the opposite side of the equation, by either adding or subtracting it. At this point your equation will be set up By = -Ax + C. Then you want to divide the B from the By and the rest of the equation. Therefore you will have y = - Ax/B + C/B. This is the same thing as the slope-intercept form, just a few of the letters are different.
Example 1:
Change from standard to slope form
8x + 4y = 16
8x + 4y = 16 first subtract 8x
4y = -8x + 16 then divide all by 4
y = -2x + 4 slope form
Example 2:
6x + 3y = 21
6x + 3y = 21 subtract 6x
3y = -6x + 21 then divide all by 3
y = -2x + 7 slope form
C. I think so I don't know but that's what I think...
I think #1 is -1/2 but im not sure i dont know about the other answers
Answer:
The height of tree house is 70.71 feet
Step-by-step explanation:
We are given that A 100-foot rope from the top of a tree house to the ground forms a 45∘ angle of elevation from the ground
Refer the attached figure
Length of rope AC = Hypotenuse =100 feet
The top of a tree house to the ground forms a 45∘ angle of elevation from the ground =
We are supposed to find the height of tree house i.e.AB = Perpendicular
So, Using trigonometric ratio
Hence The height of tree house is 70.71 feet
