Answer:
C = 125
Step-by-step explanation:
Since a straight line is 180 degrees. We can conclude that:
10x + 15 + 5x = 180
And that:
C = 10x + 15
First we need to find the value of x to find C. So,
10x + 15 + 5x = 180
15x + 15 = 180
- 15 -15
15x = 165
15x/15 = 165/15
x = 11
So now, we need to substitute the values of x into C and solve it.
C = 10(11) + 15
= 110 + 15
= 125
Answer:
(-1 / 4)x + y = -1.75
Step-by-step explanation:
Standard form is Ax + By = C
First I'm going to write it in point slope form, then I'm going to simplify.
Slope: (-3 + 1) / (-5 - 3) = 1 / 4
(y + 1) = 1 / 4(x - 3)
y + 1 = x / 4 - 3 / 4
(-1 / 4)x + y = -1.75
This might be wrong because I don't really like to use standard form.
Answer:
A
Step-by-step explanation:
A cube has 6 sides
Only one side of the cube has 2 on it
The probability of getting 2 would be 1/6
Only one side of the cube has 6 on it
The probability of getting 6 would be 1/6
For both events to happen together
1/6 x 1/6 = 1/36
This is the equation which you can add:
![[c + (3(c + 2))] + [5c]](https://tex.z-dn.net/?f=%5Bc%20%2B%20%283%28c%20%2B%202%29%29%5D%20%2B%20%5B5c%5D)
Simplify:
![[c + 3c + 6] + [5c] = 9c + 6](https://tex.z-dn.net/?f=%5Bc%20%2B%203c%20%2B%206%5D%20%2B%20%5B5c%5D%20%3D%209c%20%2B%206)
And, that's your answer!
Answer:
line1:y=2x+3
Gradient1=2
Let line2 be the line passes through (-4,1)and perpendicular to line1.
Because line2 and line1 are perpendicular, (gradient of line2) (gradient of line1) =-1
Gradient of line2=-1/2
Equation of line2:y-y1 =m(x-x1)
:y-1 =(-1/2)[x-(-4)]
:(y-1)(-2)=(x+4)
:-2y+2 =x+4
:-2y+2-x-4=0
:-x-2y-2 =0
:x+2y+2 =0
*notes:gradient=m
