Use graphing to find the solution of the system of equations. -x^2+y=1, -x+y=2

ANSWER

or

EXPLANATION

For

We make y the subject to obtain,

We can easily graph this function, because we just have to transform the graph of by shifting the intercept up to .

As for the straight line, ,

We find the intercepts as follows,

When .

When .

We plot the points and

.

We now draw the two graphs on the same graph sheet. The intersection of the two graphs gives the solution to be

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

answer: 1 + 1 = 11
