Answer:o

Step-by-step explanation:o

Answer:

1) INF

2) NS

Because:

1 is INF because both sides of the equation are the same

x can be replaced with any number therefor, there are infinite solutions.

2 is NS because you are left with 12=2 so there would not be a solution.

Answer:

-1/2? i dunno

Step-by-step explanation:

Answer:

[tex]-1/2[/tex]

Step-by-step explanation:

[tex]-1/2[/tex] is the answer because [tex]-1/2[/tex] is the gradient of the line in the slope. 3 is the y inter. Which is where the line goes over the y-axis.

Hope this helps! (^-^)

Answer:

c

Step-by-step explanation:

90+ (50-10)= 130+50=180

Firstly, let's write these out to help us see:

[tex]\pi[/tex] = 3.1415

3

[tex]\sqrt{11}[/tex] = 3.3166

We can see that [tex]\sqrt{11}[/tex] is 0.3166 greater than 3, and 0.1751 greater than pi. Therefore, it's the biggest number.

Pi is second biggest because it is less than [tex]\sqrt{11}[/tex] but greater than 3.

Therefore, your order would be:

3, [tex]\pi[/tex], [tex]\sqrt{11}[/tex]

Hope this helps! :)

simple interest formulae = PRT/100

where

p stands for percentage (2%)

r stands for rate ( 900)

t stands for time (2 years )

2×900×2/100

=3600/100

=36

Deposit interest

Deposit Interest in 2 years

= D × i × T/365 days

= 900 pounds × 2% × (365 × 2 years)/365 days

= 900 pounds × 0.02 × 730 days/465 days

= 900 pounds × 0.02 × 2

= 36 pounds

Her Deposit in 2 years

= 900 pounds + 36 pounds

= 936 pounds

So, her deposit if she will withdraw is 936 pounds

the last choice

Step-by-step explanation:

i mean, you judt gotta find the points of the letters.

you can first find the coordinates of point A, which is 3, 2

based off of that, the rest of the answer choices don't have A as 3, 2.

so, with Process of Elimination, its the last one.

The translation preserves side lengths and angles, but the vertical stretch does not preserve side lengths and angles of the preimage is correct statement.

A translation is a type of transformation that takes each point in a figure and slides it the same distance in the same direction.

A transformation allows something(shape) to  moves, flip, or changes a shape (called the preimage) to create a new shape.

The length or angle of the image is not changed by translation but stretching will change the angle of image.

By  transformation rules A,B C are false.

The translation preserves side lengths and angles, but the vertical stretch does not preserve side lengths and angles of the preimage. is correct statement.

Hence, The translation preserves side lengths and angles, but the vertical stretch does not preserve side lengths and angles of the preimage.

b<-21

Step-by-step explanation:

1/3b+1<-6

1/3b<-7

b<-21

Answer:

b <  - 21

Step-by-step explanation:

[tex]\frac{1}{3}[/tex] b + 1 < - 6 ( subtract 1 from both sides )

[tex]\frac{1}{3}[/tex] b < - 7 ( multiply both sides by 3 to clear the fraction )

b < - 21
