Answer:

25X + 25Y = 1700

25X + 100Y = 3200

Step-by-step explanation:

Given that the principal of a high school spent $1700 for X desk and Y chairs at $25 each. Then, the equation will be

25X + 25Y = 1700 ....... (1)

If he had bought half the number of desk in twice the number of chairs he would have spent 1600. That is

25(X/2) + 25(2Y) = 1600

25X/2 + 50Y = 1600

Find the LCM and cross multiply

25X + 100Y = 3200 ........(2)

Y = – 1.3(x + 3)2 – 9
Naddika [18.5K]

Given equation, y = – 1.3(x + 3)2 – 9 is in slope intercept form.

Step-by-step explanation:

Slope intercept form standard formula:

                          y = mx + c

where,

         y= y intercept

         x= x intercept

        m = slope

        c = constant

We are given:

                          y = - 1.3(x + 3)2 - 9

                          y = - 2.6x + 7.8 - 9

                          y = -2.6x -1.2

So,

                 Slope = m = -2.6

                  constant = 1.2
