Answer: hello! have a good day! :)))

<em>P = 2</em>

F (x) = cx + 3
algol13

<em>If f(1) = 1 that means c is -2 because when you substitute x = 1 and when c = -2, you'll get f(1) = -2(1)+3 = -2+3 = 1</em>

<em>So the constant c is -2 and that means the value of f(-4) is</em>

<em>f(-4)=-2(-4)+3=8+3=11</em>

<em />

<em>Thus, the value of f(-4) is 11.</em>

<em />

<em>About why does "c" have to be -2, here's the proof.</em>

 <em>Given y = f(x), therefore.</em>

<em>y=cx+3</em>

<em>Since when x = 1 and y = 1, then Substitute x = 1 and y = 1, thus 1 = c+3</em>

<em>1 - 3 = c and therefore, -2 = c #</em>

<em>So this is the proof that c = -2</em>

In the rhombus, m angle 1 = 18x, m angle 2 = x+y and m angle 3 = 30z. Find the value of x+y+z. The diagram is not drawn to scale
Ratling [72]

The value of x+y+z = 93

<u>Explanation:</u>

<u></u>

angle 1 = 18x

angle 2 = x+y

angle 3 = 30z

In rhombus, the diagonals intersect at 90°

Therefore,

angle 1 : 18x = 90

                  x = 90/18 = 5

angle 2: x+y = 90

              5+y = 90

                  y = 85

angle 3: 30z = 90

                   z = 90/30 = 3

Value of x+y+z = 5+85+3 = 93

Thus, the value of x+y+z = 93

In a highway building project, 32 miles of a new highway have been
pychu [463]

Answer: 105 miles

Step-by-step explanation:

You can write an equation for this problem and solve it.

32 miles=1/3x-3, where x is equal to the total length of the highway.

35=1/3x, and then you multiply by 3, to get x=105
