Answer:

y = (-1)*2^(x + 1)

Step-by-step explanation:

This one is not a line. It is something raised to a power. In addition, there is an ugly minus sign somewhere.

First of all, every answer is some sort of power of 2. All of them are 2^x but we don't exactly know how x words. It is not a simple y = 2^x because the first one is - 4 not - 2.

So there is an extra power somehow.

Try

y = 2^(x + 1) That looks promising

x = 1

y = 2^(1 + 1)

y = 2^2

y = 4

===============

Try another one

x = 2

y = 2^(2 + 1)

y = 2^3

y = 8

==============

I think you'll find that the other two are well behaved. and come to the answer (except for the minus) as they should.

What about that minus.

y = (-1)*2^(x + 1) should give a minus y value for any term.

(1,-4) (2,-8)

(-8+4)/(2-1)= -4/1= -4

y + 4 = -4(x - 1)

y + 4 = -4x + 4

y = -4x

the answer is linear

Consider the circles shown. Circle A has a radius of 6 inches. Circle B has a radius 20% greater than
butalik [34]

Answer:

Answer should be D and E

Step-by-step explanation:

First, you need to figure out the radius of B.

As radius of A is 6 in, 20% of 6in would be 1.2in. So total radius of B = 6+1.2 = 7.2

Now you get the radius of B, calculate th area of B using the formula πr^2.

= π(7.2)^2 = 162.86 = area of B

Now, all answers except D and E is smaller than B. So, the answer would be D and E.

Choch Question 3 3.1 Construct the following triangles: 3.1.1 ADEF with EF = 7cm, ​
olasank [31]

We have to construct a triangle DEF with EF = 7 cm. It is given that we have to make an angle of 50⁰ at E and at F.

Steps to make a triangle DEF:

Step 1: Draw a line segment EF equal to 7 cm, using a ruler.

Step 2: Put the center of the protractor on the one end of the line segment that is at E and make the given angle that is 50⁰.

Step 3: Make the angle of 50⁰ at F by using protractor.

Step 4: Extend the line from E and F in the direction of 50⁰. After extending the line segments, we get an intersection point, name that point D..

Step 5: The point D, is made from the intersection of the line segment from E and F.

Step 6: Hence, triangle DEF is constructed.

Simplify (8j^3-10j^2-7)-(6j^3-10j^2-j+12)
Y_Kistochka [10]
The first step for solving this expression is to remove the first set of parenthesis.
8j³ - 10j² - 7 - (6j³ - 10j² - j + 12)
When there is a "-" sign in front of the parenthesis,, you must change the sign of each term in the parenthesis. This will look like the following:
8j³ - 10j² - 7 - 6j³ + 10j² + j - 12
Eliminate the opposites in the expression
8j³ - 7 - 6j³ + j - 12
Collect the first set of like term (ones with j³) 
2j³ - 7 + j - 12
Calculate the difference between basic numbers
2j³ - 19 + j
Lastly,, use the commutative property to reorder the terms
2j³ + j - 19
Since you cannot simplify this expression any further,, the correct answer to your question is 2j³ + j - 19.
