Use substitution             3x-7=x^2+6x-17
                            x^2+3x-10=0
                            (x-2)*(x+5)=0
x=2 or -5, plug in back in, y= -1 or -22
check answers--both correct.

the answer is (2,-1) or (-5,-22)

Pls help me !!!!!!!!!!!!!!!!!!!!!!!!!!
marysya [2.9K]

Answer:

1. y^12/y^12=1

2. q^15*1/q^15=1

3. (7(123456.789)^4)^0=1

4. 2^2*1/2^5=1/2^3

5 (x^41/y^15)*(y^15/x^41)=1

Step-by-step explanation:

1. when dividing exponents, subtract the exponents. y^12/y^12=y^(12-12)=y^0=1

2. you do the same as #1

3. Any number to the power of 0 is always 1

4. 1/2^3=1/8

5. since the numerator and denominator is the same, the divide to equal 1

Hope I helped

I need help on part c !!!
expeople1 [14]

The volume of a cone with diameter d (and hence radius d/2) and height h is

V_{\rm cone} = \dfrac\pi3 \left(\dfrac d2\right)^2 h

so each scoop holds

V = \dfrac\pi3 \left(\dfrac{1\,\rm in}2\right)^2 \left(2\,\mathrm{in}\right) = \dfrac\pi6 \, \mathrm{in}^3

of coffee.

The volume of a cylinder with base diameter d and height h is

V_{\rm cylinder} = \pi\left(\dfrac d2\right)^2 h

so the coffee can contains

W = \pi \left(\dfrac{6 \, \rm in}2\right)^2 \left(6\dfrac14 \, \mathrm{in}\right) = 2025\pi \,\mathrm{in}^3

of coffee.

One full scoop then uses up \frac VW = \frac1{12,150} of the total amount of coffee in the can, so you can make 12,150 cups of coffee.
