Answer:

Option c

Step-by-step explanation:

A system of equations are given to us. And we need to solve them . The given system is

$\begin{cases} y = 2x - 3\dots 1 \\ y = x^2 - 3\dots 2 \end{cases}$

We numbered the equations here . Now put the value of equation 1 in equation 2 that is substituting y = 2x - 3 in eq. 2 .

$\implies y = x^2 - 3 \\\\\implies 2x - 3 = x^2 - 3 \\\\\implies x^2 - 2x = 0 \\\\\implies x(x-2) = 0 \\\\\implies\red{ x = 0 , 2 }$

We got two values of x as 0 & 2 . Alternatively substituting these values we have ,

$\implies y = 2 x - 3 \\\\\implies y = 2(0)-3 \qquad or \qquad y = 2(2)-3 \\\\\implies y = 0-3 \qquad or \qquad 4 - 3 \\\\\implies \red{ y = -3 , 1 }$

Thefore the required answer is ,

$\red{Option\:c} \begin{cases} (0,-3) \\ (2,1) \end{cases}$

Y = –A system of equations. y equals negative StartFraction one-half EndFraction x plus 4. x plus 2 y equals negative 8.x + 4

laila [671]

Y = -1/2x + 4

X + 2y = -8

Replace y in the second equation with the first one:

X + 2(-1/2x +4)=-8

Simplify:

X -X +8 = -8

Simplify:

8 = -8

Subtract 8 from both sides:

0 = -16

This is a false statement, so there are no solutions.

Roger and Tina took a test. Roger finished in 2 2/3 hours. Tina finished in 2 5/6 hours. Who finished first?

Roger finished first.
2 2/3 is equal to 2 4/6. And then 2 and 4/6 is less than 2 and 5/6.

Answer:

Profit = $\frac{80p+170}{p}$

Step-by-step explanation:

Cost of the Yield = $\frac{100p+200}{p}$

Cost of the labour = $\frac{10p+50}{p}$

Cost of the fertilisers = $\frac{10p - 20}{p}$

Total expenses = $\frac{10p + 50}{p} + \frac{10p - 20}{p} = \frac{20p + 30}{p}$

Profit = Cost of yield - Total expenses

$=>\frac{100p + 200}{p} - \frac{20p + 30}{p}$

$=> \frac{80p + 170}{p}$
