Answer:
8.090169944 or rounded 8.1
Step-by-step explanation:
Use SOH CAH TOA
Look at x and where it is and what you have.
First thing is to get an angle to use, 36, then to set up your equation.
___(36)=___
Figure out what you have.
You have the hypotonouse, 10, and need the adjacent,x, so you use the equation that involves H for hypotonouse and A for adjacent.
You set up your equation using COS, as you are using CAH.
Cos(36)=x/10
X is over ten sure to CAH C-cos A-adjacent and H-hypotonouse
Switch it around to make it equal to x
10*Cos(36)=x
You input it into your calculator. [10] [COS] [36] [ENTER] and you get the answer.
Round however is needed.
Answer:
18
Step-by-step explanation:
mack has 18cats because she has 2×9 cats as Wayne 2×9 is 18
This is what it is 7 + 6=12-2=10
Convert the equation to the slope-intercept form.
![4y-6x+12=0 \\ 4y=6x-12 \ \ \ |\div 4 \\ y=\frac{6}{4}x-\frac{12}{4} \\ y=\frac{3}{2}x-3](https://tex.z-dn.net/?f=4y-6x%2B12%3D0%20%5C%5C%0A4y%3D6x-12%20%5C%20%5C%20%5C%20%7C%5Cdiv%204%20%5C%5C%0Ay%3D%5Cfrac%7B6%7D%7B4%7Dx-%5Cfrac%7B12%7D%7B4%7D%20%5C%5C%0Ay%3D%5Cfrac%7B3%7D%7B2%7Dx-3)
In the
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
form,
![m](https://tex.z-dn.net/?f=m)
is the slope.
![y=\frac{3}{2}x-3 \\ m=\frac{3}{2}=1\frac{1}{2}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B3%7D%7B2%7Dx-3%20%5C%5C%0Am%3D%5Cfrac%7B3%7D%7B2%7D%3D1%5Cfrac%7B1%7D%7B2%7D)
The slope is equal to
![1 \frac{1}{2}](https://tex.z-dn.net/?f=1%20%5Cfrac%7B1%7D%7B2%7D)
.
