The y-intercept of

f(x) = -2x - 1

is y = -1 .

This function is in slope-intercept form, which uses the following formula:

$y = mx + b$

m is the slope, and b is the y-intercept of the line.

In f(x) = -2x - 1, the slope is 2, and the y-intercept is -1, or (0, -1).

What is the square root of 16x^<br> 36?

Vsevolod [243]

Note that $\sqrt[2]{x}=x^{\frac{1}{2}}$

$\sqrt[2]{16x^{36}}=\sqrt[2]{4^2x^{18\cdot2}}$

$4^{2\cdot\frac{1}{2}}x^{18\cdot2\cdot\frac{1}{2}}=4^{\frac{2}{2}}x^{\frac{18\cdot2}{2}}$

$\boxed{4x^{18}}$

Hope this helps.

* 4. A circle is divided into ten equal sectors.

Fiesta28 [93]

Answer:

a. Find the measure of each central angle.

The central angle of a circle = 360 °

Now Pie is cut into 10 equal sectors

Angle of each sector is given by

Angle of sector = Total central angle/number of sectors

$= {360}^{0} \div 10$

$= {36}^{0}$

Hence , the central angle of one slice of pie is 36°

b. If the diameter is 50 in., find the length of an arc of one of the sectors.

length of an arc of one of the sectors =

$= \frac{1}{n} \times 2\pi \times r$

$= \frac{1}{10} \times 2\ \frac{22}{7} \times 50$

$= 31.42 \: in$

Step-by-step explanation:

Total amount of apples in one bag:

$x + y + z$

Hence, total amount of apples in two bags:

$2(x + y + z)$

$2x + 2y + 2z$

$x + x + y + y + z + z$

Hence, B, D and E are correct.

A is incorrect because you are adding 2 more apples on top of the total amount of apples in one bag, and you cannot assume that there are 2 apples in each bag.

C is incorrect because you are multiplying the apples together, but you are supposed to add them up to find the total.

F is incorrect because you are finding 1/2 a bag.
