Use graphing to find the solution of the system of equations. -x^2+y=1, -x+y=2
vladimir2022 [97]

ANSWER


x=-0.62 or x=1.62




EXPLANATION


For -x^2+y=1



We make y the subject to obtain,



y=x^2+1


We can easily graph this function, because we just have to transform the graph of y=x^2 by shifting the intercept up to 1.



As for the straight line, -x+y=2,


We find the intercepts as follows,



When y=0,x=-2.


When x=0,y=2.


We plot the points (-2,0) and


(0,2).



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


x=-0.62 or x=1.62


See graph

What is 15% of 135, show your work
SIZIF [17.4K]

Answer:

20.25

Step-by-step explanation:

Percentage solution with steps:

Step 1: Our output value is 135.

Step 2: We represent the unknown value with $x$

.

Step 3: From step 1 above,$135=100\%$

.

Step 4: Similarly, $x=15.\%$

.

Step 5: This results in a pair of simple equations:

$135=100\%(1)$.

$x=15.\%(2)$

.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{135}{x}=\frac{100\%}{15.\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{135}=\frac{15.}{100}$

$\Rightarrow x=20.25$Therefore, $15.\%$ of $135$ is

sorry if it took to long have a great day and brainliest is appreciated!!!!!

Practice solving quadratic equations.
goldfiish [28.3K]

Answer:

x=4, 3/2

Step-by-step explanation:

3(x-4)(2x - 3) = 0

Using the zero product property

x-4 = 0    2x-3 =0

x=4           2x = 3

                    x = 3/2
