Hello! :)

Answer:

$\huge\boxed{x = (\frac{b}{a})(P+c)}$

$\frac{a}{b}x - c = P$

Solve for x:

Begin isolating the variable by adding "c" to both sides:

$\frac{a}{b}x - c + c= P + c$

$\frac{a}{b}x = P+ c$

Divide both sides by a/b, or multiply by the reciprocal (b/a)

$(\frac{b}{a}) \frac{a}{b}x = (\frac{b}{a})(P + c)$

Therefore:

$x = (\frac{b}{a})(P + c)$

You are putting away money to spend at the school carnival. On day 6, you had $5. You were able to save

skad [1K]

Answer:

We have the equation of the line as;

y = 1.80x - 5.80

Step-by-step explanation:

Let us have a plot of the amount saved in dollars to the day number

So we have the amount as y axis values and the day as x axis values

from the question, we can identify the points as;

(6,5) and (11,14)

Mathematically the equation of a straight line can be represented by the equation;

y = mx + b

where m is the slope and b is the y intercept

So, we calculate the slope using the two points above

We have the formula as;

m = (y2-y1)/(x2-x1)

(x1,y1) = (6,5)

(x2,y2) = (11,14)

m = (14-5)/(11-6) = 9/5 = 1.8

So we have the equation as;

y = 1.80x + c

To get the value of c, we use any of the two points

Let us use the point (6,5)

we substitute 6 for x and 5 for y

So, we have ;

5 = 1.8(6) + c

c = 5-1.8(6)

c = -5.8

So we have the equation as;

y = 1.80x - 5.80

A triangle has an area of 900m2 . If a parallelogram has the same height and base as the triangle, what is the area of the paral

timama [110]

Answer:

1800 $m^{2}$ is the area of parallelogram.

Step-by-step explanation:

Given that:

Area of a triangle = 900 $m^{2}$

To find:

Area of a parallelogram which has same height and base as that of the given triangle.

Solution:

First of all, let us have a look at the formula for Area of a parallelogram:

$Area_{Par} = Base \times Height$ ...... (1)

So as to find the area of a parallelogram, we need to have the product of Base and Height of Parallelogram.

Now, let us have a look at the formula for area of a triangle:

$Area_{Tri} = \dfrac{1}{2} \times Base \times Height$

Given that height and base of triangle and parallelogram are equal to each other.

So,the product of base and height will also be equal to each other.

$900 = \dfrac{1}{2} \times Base \times Height\\\Rightarrow Base \times Height = 2 \times 900\\\Rightarrow Base \times Height = 1800\ m^2$

By equation (1):

Area of parallelogram = 1800 $m^{2}$
