Does the point (0,4) make either equations y=-2x and y=x+3 true? Explain.

Nikolay [14]

Answer:

Neither

Step-by-step explanation:

To verify, we substitute the values in the equations:

$y = -2x\\y = -2 \times 0\\y = 0$

however, the value should be 4. Hence this equation does not satisfy the co-ordinate.

$y = x+3\\y= 0+3\\y = 3$

however, the value should be 4. Hence this equation does not satisfy the co-ordinate.

Which of the following expressions is equivalent to the radical expression?

qwelly [4]

The correct answer is B) $m^{2/3}n^{5/3}$ .

The denominator of the exponent is the root we are taking. The numerator is the exponent of the radicand. This means 3 will be the denominator, since it is a cubed root, and 2 will be the numerator of m while 5 will be the numerator of n.

john read the first 114 pages of a novel which is 3 pages less than 1/3 of the novel. write the equation

tatyana61 [14]

The equation is:

$114=\frac{p}{3}-3$

And

Total number of pages are 351

Step-by-step explanation:

The equation has to be formed by using the given information.

Let p be the total number of pages in the novel

Then

1/3rd of the p will pe:

$\frac{p}{3}$

Total pages read by John = 114

Then according to the statement

$114=\frac{p}{3}-3$

We can solve the equation to get the total pages of the novel

$114=\frac{p}{3}-3\\Adding\ 3\ on\ both\ sides\\114+3=\frac{p}{3}-3+3\\117=\frac{p}{3}\\Multiplying\ both\ sides\ by\ 3\\3*117 = \frac{p}{3}*3\\p=351$

The equation is:

$114=\frac{p}{3}-3$

And

Total number of pages are 351

According to Greek mathematician Zeno, if each bounce of a ball is half the height of the bounce before it,the ball will never s

vovikov84 [41]

From the diagram associated with this question it can be seen that the first bounce was 1 units high, thus the second bounce is 1 / 2 = 0.5 units high and the third bounce is 0.5 / 2 = 0.25 = 1/4 units high.

Given that B represents the second bounce and C represents the first bounce, the <span>fractions in hundredths that should be written at points B is 0.50 while at point C is 0.25</span>
