A triangle has sides with lengths of 5x-7,3x-4 and 2x-6. What is the perimeter of the triangle?

boyakko [2]

The perimeter is the sum of all the sides, so P = (5x -7) + (3x-4) + (2x -6). Then group like terms so you have p = 5x + 3x + 2x -7-4-6 and end up with P = 10x - 17

Solve negative 5 over 2, the whole multiplied by x minus 5 equals negative 55.

astraxan [27]

Answer:

-24

Step-by-step explanation:

$- \frac{5}{2} x \: - 5 = 55$

Multiply through by the denominator (that is, 2)

$= 2 \times ( - \frac{5}{2} x) \: - 5(2) = 55(2)$

$= - 5x - 10 = 110$

Collect like terms

$- 5x \: = 110 +10$

$- 5x = 120$

Divide through by - 5x

$\frac{ - 5x}{ - 5} = \frac{120}{ - 5}$

$x = - 24$

Anyone help me ASAP, its due in an hour, plz show all the working, THANK YOU SO MUCH

Answer:

Step-by-step explanation:

First, start out with the parent function:

$y = b^{x}$

Now, we look at the transformations, and make the equation.

We see that the graph shifted down 4 units, since the graph's horizontal asymptote is at y = -4.

$y = b^{x} - 4$

We see point (0, -3) to point (1, -1). The value of b would be 3. The reason is that when you plug 0 in, you get 1, then 1 - 4 equals 3. (0, -3),

Then, when you plug in 1, you get 3, then 3 - 4 equals -1. This matches up with the graph.

This is the answer:

$y = 3^{x}-4$
