How can x^2=x^2+2x+9 be set up as a system of equations

Mathematics
1 answer:
Nikitich [7]3 years ago

Answer: \left \{ {{y=x^{2} } \atop {y=x^2+2x+9}} \right.

Step-by-step explanation:

1. As you can see, x^{2} is equal to the other quadratic equation x^2+2x+9.

2. Then, this would the same as write the quadratic equations as following:

y=x^{2}

y=x^2+2x+9

3. And then set them equal to each other, as you can see below:

y=y

Substituting, you obtain:

x^{2}=x^2+2x+9

3. Keeping the above on mind, you can set up the given equations as a system of equations as folllowing:

\left \{ {{y=x^{2} } \atop {y=x^2+2x+9}} \right.

Sam used his calculator to find cos 1.75. he wrote down cos 1.75 = .999. how could sam recognize that his answer is incorrect?
ZanzabumX [31]

Answer:

Step-by-step explanation:

Since π=3.14 and 1.75 should be half of π so cos(1.75) should be in the approximation of \frac{\sqrt{2}}{2} or 0.7.

Clearly Sam's calculator is in the degree mode since cos(1.75^{\circ})

is about .999 and obviously, \frac{{\pi}}{2}, So on the unit circle, it will be in the second quadrant.

Thus, cos(1.75) is negative.

Which associations best describe the scatter plot?
LenKa [72]

Answer: Here you go hope this helps

If a line is drawn through (twenty, seventy) and (twenty-five, sixty), then you can use the points in getting the equation.

Slope is = (60-70)/(25-20) = -2

Using the two-point slope form, y – y1 = m(x – x1)

               y – 70 = -2(x – 20)

               y – 70 = -2x + 40

               y = -2x + 110

PLS HELP ASAP THANKS ILL GIVE BRAINLKEST PLS THANKS
Amanda [17]

Answer:

Step-by-step explanation:

The y intercept is where x = 0.

X and y are both increasing by 5.

If you add five to the bottom row of the table we see that the next row of the table is x = 0 and y = 13.

This means that (0,13) is the y-intercept and 13 is your correct answer.
