The y-intercept of 

f(x) = -2x - 1

is  y = -1 .
zloy xaker [14]3 years ago
4 0
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

I will pick brainliest first come, first serve! I need help! Give me an answer that makes sense!
nordsb [41]

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)

or

2x + 2y + 2z

or

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.
