What is the image of (2, 4) after a reflection over the x-axis?

1 answer:

5 0

If we reflect about a line that is parallel to the x-axis, then the x-coordinate of the point (that is reflected) will remain the same, thus the image of (2,-4) has x-coordinate 2 and thus the point is of the form (2,b).

Jax has a weekly math test. His scores on the last 5 tests are 78,92,86,94,95. What score does he need to have an average of 90

lara [203]

Answer:

x = 95

Step-by-step explanation:

Given that,

Jax scores on the last 5 tests are 78,92,86,94,95.

We need to find the score he need to have an average of 90.

The formula for average of few number is given by :

Average = sum of observations/total no of observation

Let he score x in test 6. So,

$90=\dfrac{78+92+86+94+95+x}{6}\\\\90=\dfrac{445+x}{6}\\\\540=445+x\\\\x=95$

So, he must score 95 in the next test so that its average is 90.

azamat

Answer:

(x + 2)²(x - 3)² = 0

Step-by-step explanation:

Since we have a degree of 2 and double of the same roots, we know that each root would have a multiplicity of 2. Therefore, our answer is(x + 2)²(x - 3)² = 0
