Answer:

Graph 1

Step-by-step explanation:

Given : Inequality y\leq 1-3x

To find : Which is the graph of the equation?

Solution :

Inequality y\leq 1-3x

We determine the x-intercept and y-intercept,

  • For x-intercept, put y=0

0\leq 1-3x                  

Add 3x both side,

3x\leq 1            

Divide both side by 3,

x\leq \frac{1}{3}        

x\leq 0.33            

Point is (0.33,0)

  • For y-intercept, put x=0

y\leq 1-3(0)              

y\leq 1                

Point is (0,1)

As there is equal and less than so there is a complete line not dotted line.

The graph is passing through the points (0.33,0) and (0,1) and drawn LHS of the graph.

Therefore, The correct option is graph 1.

Refer the attached figure below.

<u>it is the first one</u>, because y CAN be 1-3x, so the line is solid. then, it is a simple matter of placing it correctly based on the y-intercept, which is one. the shading goes under the line because it is <u>less than </u>or equal to

If a1=10 and an+1=-5an-1 then find the value of a4<br><br>Please explain!
Umnica [9.8K]

Answer:

a_4=-1271

Step-by-step explanation:

We are given that:

a_1=10

And:

a_{n+1}=-5a_n-1

And we want to find:

a_4

This is a recursive formula. So we can simply substitute in each value. For instance, a₂ will be:

a_2=a_{(1)+1}=-5a_{1}-1=-5(10)-1=-51

Thus, a₃ will be:

a_3=a_{(2)+1}=-5a_2-1=-5(-51)-1=254

Finally, a₄ will be:

a_4=a_{(3)+1}=-5a_3-1=-5(254)-1=-1271

Can tell me if it's correct? If it's wrong, can you tell me the correct answer and how to solve it?
Sergio [31]

Answer:

C is a right triangle

Step-by-step explanation:

To determine if the triangle is right use Pythagoras' identity

A

9.4² = 88.36

6.4² + 7.1² = 91.37

88.36 ≠ 91.37 , thus not a right triangle

B

8.4² = 70.56

5.2² + 6.3² = 66.73

70.56 ≠ 66.73 , thus not a right triangle

C

9.7² = 94.09

6.5² + 7.2² = 94.09

Thus C is a right triangle

D

8.4² = 70.56

5.1² + 7.3² = 79.3

70.56 ≠ 79.3 , thus not a right triangle

A point has coordinates A(-2, 4). Find the coordinates of its image if it's translated by (x - 2, y - 1). A'(0, 5) A'(0, 3) A'(-
Setler79 [48]

Answer:

A'(-4, 3)

Step-by-step explanation:

The given point is A(-2,4).

If this point is translated by the rule:

(x,y)\to (x-2,y-1), then we can obtain the image of A(-2,4) by plugging x=-2 an y=4 into the rule.

\implies A(-2,4)\to A'(-2-2,4-1)

\implies A(-2,4)\to A'(-4,3)

The correct choice is  A'(-4, 3)

PLEASE HELP ASAAP 25 PTS + BRAINLIEST TO RIGHT/BEST ANSWER
Nutka1998 [239]

Let i = sqrt(-1) which is the conventional notation to set up an imaginary number

The idea is to break up the radicand, aka stuff under the square root, to simplify

sqrt(-8) = sqrt(-1*4*2)

sqrt(-8) = sqrt(-1)*sqrt(4)*sqrt(2)

sqrt(-8) = i*2*sqrt(2)

sqrt(-8) = 2i*sqrt(2)

<h3>Answer is choice A</h3>
