Solve the following :- 2n > 14. n > _____ . 2. n/5≥ 11. n ≥ _______. 3. –3y ≤ –18. y ≥ _______

ahrayia [7]

The answers to the numbers are shown below.
1.) Divide both sides by two to yield an answer of n > 7.
2.) Cross multiply by multiplying the denominator, 5, by 11. This gives an answer of n ≥ 55.
3.) Divide both sides by -3. Since we have an operation involving a negative number, we invert the sign. Thus, the answer is y ≥ 6.

Solve each equation by finding all roots x^4-16=0

Alexandra [31]

Add both sides by 16
so you'll have x^4 =16
take the 4th root of both sides and you'll get x= 2

Sophia uses 18 beads to make a necklace. Three sixths of the beads are purple. How many beads are purple?

tatuchka [14]

Answer:

9 beads are purple

Step-by-step explanation:

we know that

To find out how many beads are purple, multiply the total beads by the fraction of the beads that are purple

so

$18(\frac{3}{6})=9\ beads$

therefore

9 beads are purple

Another way to solve the problem is convert the fraction in percentage

we have

$\frac{3}{6}=\frac{1}{2}=0.50*100=50\%$

so

If the total are 18 beads

50% is 9 beads

therefore

9 beads are purple

Find equations of the line that is parallel to the z-axis and passes through the midpoint between the two points (0, −3, 7) and

tia_tia [17]

Answer:

$\vec{r}(t)=\left$

In parametric form:

$x=-1, y=\displaystyle\frac{1}{2}, z=4+t$

Step-by-step explanation:

We first find the mid point:

$\displaystyle\left(\frac{0+(-2)}{2},\frac{-3+4}{2},\frac{7+1}{2}\right)=\left(-1,\frac{1}{2},4\right)$

Then, a vector parallel to the z-axis is:

$\vec{v}=\left< 0,0,1 \right>$

Then remember the equation of a line passing through point $(x_o,y_o,z_o)$ and parallel to the vector $\vec{v}=\left$ is:

$\vec{r}(t)=\left+t\left$

So, in this problem we get:

$\vec{r}(t)=\left+t\left$

After combining the two vectors:

$\vec{r}(t)=\left$

In parametric form:

$x=-1, y=\displaystyle\frac{1}{2}, z=4+t$
