Answer:

C. y+4=-3(x-3)

Step-by-step explanation:

The point-slope format is a way to represent the equation of a line. It involves using a point on the line and relating it to the slope in such a way that one can find any point on the line using the equation. One is asked to find the equation of a line in point-slope form. The general format for the point-slope form of a line is the following;

y-h=m(x-k)

Where the point on the line that is being used is (h,k). The parameter (m) represents the slope or rate of change in the line. The slope is often referred to as the (\frac{rise}{run}) and can be found using the following formula.

\frac{y_2-y_1}{x_2-x_1}

Where (x_1,y_1) and (x_2,y_2) are points on the line. As one can see the following points can be found on the line:

(3,-4), (0, 5)

Substitute these points into the slope formula and solve for the slope;

\frac{y_2-y_1}{x_2-x_1}

= \frac{(5)-(-4)}{(0)-(3)}

= \frac{5+4}{0-3}\\

= \frac{9}{-3}

= -3

Now substitute the slope into the given formula. As per the problem, one is supposed to use the point (3, -4) in the formula.

y-h=m(x-k)

Substitute the slope;

y-h=-3(x-k)

Substitute the point;

y+4=-3(x-3)

Doug bought a new car for 25,
pentagon [3]
This is exponential decay which can be expressed as:

y=ab^t, y=final value, a=initial value, b=rate, t=time

In this case a=25000, r=(100-20)/100=0.8 so

y=25000(0.8^t), so in 4.5 years...

y=25000(0.8^4.5)

y≈$9158.93  (to nearest cent)

The expression below is the factorization of what trinomial-1(x+5)(x+6)
Nadya [2.5K]

Answer:

-x^2 - 11x -30

Step-by-step explanation:

Solve using foiling. Ignore the -1 to begin with and just look at the part in parenthesis. Do x from the first parenthesis times the stuff in the second parenthesis.

ie: x(x) and x(6)

ie: x^2 + 6x

Then do the 5 times the things in the second parenthesis.

ie: 5(x) and 5(6)

ie: 5x + 30

Then add what you got from multiplying the first value to what you got from multiplying the second.

ie: x^2 + 11x + 30

This is a trinomial because it has three different variables. Now change all the signs to negative because of the -1 out front.

ie: -x^2 - 11x -30

Definition of transposition of formulae​
neonofarm [45]

The process of expressing w in terms of A and l is called transposition or changing the subject of the formula. The methods used to change the subject of the formula are the same as those used for solving equations.
