So you could find the answer for A and B two different ways by adding and subtracting the answers for example 180 subtracted by 75 gives you an answer and then 75 + and answer use 180

Compute the value of the discriminant and give the number of real solutions of the quadratic equation.

Sergio039 [100]

$-2x^2+6x-3=0 \\ \\
a=-2 \\ b=6 \\ c=-3 \\ \Delta=b^2-4ac=6^2-4 \times (-2) \times (-3)=36-24=12$

The value of the discriminant is 12.
Since the discriminant is greater than zero, the equation has two real solutions.

How many people swam fewer than 30 laps?

Bas_tet [7]

Answer:

3 people

Step-by-step explanation:

Reading a stem & leaf plot can be hard!

Remember in the middle or whichever side is single digits divided by the line is your tens place values.

The 2 has two values on the other side, giving us 23 & 29 laps.

The 1 has one value on the other side, giving us 11 laps.

The 0 has no other value, so there is no data for that row.

There were 3 data points below 30, & these were 11, 23, & 29.

Hope this helped. :)

Eric was rock climbing. At one point, he stopped and climbed straight down 2\dfrac{1}{2}2 2 1 2, start fraction, 1, divided by

podryga [215]

Answer:

Hence, Eric's elevation changed $4\frac{1}{4}$ meters above. So after the 2 moves, he is up by $4\frac{1}{4}$ meters.

Step-by-step explanation:

Let us assume "negative" as climbing up and "positive" as climbing up. Here we need to find the change in elevation.

$2\frac{1}{2}$ meters down means $-2\frac{1}{2}$ .
$6\frac{3}{4}$ meters up means $+6\frac{3}{4}$ .

Now we have:

$=-2\frac{1}{2} + 6\frac{3}{4}\\\\=-\frac{5}{2} +\frac{27}{4} \\\\=\frac{-5(2)+27}{4} \\\\=\frac{-10+27}{4} \\\\=\frac{17}{4} = 4\frac{1}{4}$
