Which following is not a function

Answer:

Hey there!

15x-43+8x+18=90

23x-25=90

23x=115

x=5

RSQ=15(5)-43, or 32

TSQ=8x+18, or 58

Let me know if this helps :)

Step-by-step explanation:

Answer:

The answer is 45i + 18

since i *i=-1

Answer:

y = -10x + 5 and y = 2/5x + 1

Step-by-step explanation:

slope-intercept form is y = mx + b, where m = slope and b = y-intercept.

for your first problem, just plug in the m and b values to complete the equation.

1.) y = mx + b ⇒ y = -10x + 5

plug in -10 for x (slope) and 5 for b (y-intercept)

and for the second problem...

since you're given a value for slope as well as a coordinate pair, all you need to do is plug those values into the equation for their respective variables and then solve for b. (it doesn't matter what order you plug values in, but i'm going to fill them in in the order of the equation; y, m, and x)

1.) plug in -1 for y

y = mx + b ⇒ -1 = mx + b

2.) plug in 2/5 for m

-1 = mx + b ⇒ -1 = 2/5x + b

3.) plug in -5 for x

-1 = 2/5x + b ⇒ -1 = 2/5(-5) + b

now it's time to solve for b! start by multiplying 2/5 and -5.

-1 = 2/5(-5) + b ⇒ -1 = -2 + b

add 2 to both sides of the equation. on the right side, it cancels itself out. on the left side, adding 2 to -1 gives you 1.

and you're left with 1 = b! :)

therefore, y = 2/5x + 1

i hope this helps! have a great day <3

Answer:

-5.7-4.2=-9.9 is answer

Answer:

3.6 hours

Step-by-step explanation:

The computation of the number of hours will the battery last is given below:

Given that

The capacity of her battery is 2 by 5

And, it declines 1 by 9 for every hour

So,

[tex]= \frac{2}{5}\times \frac{9}{1}\\\\= \frac{18}{5}\\\\= 3\frac{3}{5}[/tex]

= 3.6 hours

Answer:8x+2

Step-by-step explanation:

Answer:

5(4) = 20

Answer:

300

Step-by-step explanation:

Given data

P=5000

R= 6%

T= 1 year

The simple interest formula is

SI= PRT/100

SI= 5000*6*1/100

SI= 30000/100

SI= 300

Hence the simple interest is 300

Answer:

>

Step-by-step explanation:

-12 is closer to 0 than -41 would be therefore -12>-41.

Answer:

>

Step-by-step explanation:

Looking at a number line, -41 is farther from 0 than -12.

See the image below.

The farther left a number is on a number line, the smaller it is.

The farther right a number is on the number line, the larger is it.

So:

-12 > -41

Answer:

The sequence is geometric

The common ratio is 0.5

Step-by-step explanation:

In the arithmetic sequence, there is a common difference between each two consecutive terms

In the geometric sequence, there is a common ratio between each two consecutive terms

Let us check the given sequence

The first 3 terms are 12, 6, 3

6 - 12 = -6

3 - 6 = -3

There is no common difference between the consecutive terms

The sequence is not an arithmetic sequence

6 ÷ 12 = 0.5

3 ÷ 6 = 0.5

There is a common ratio between each two consecutive terms

The sequence is a geometric sequence

The common ratio is 0.5

Answer:

An arithmetic

Common difference

Marbles:

5 red

3 green

4 yellow

Total marbles = 5 + 3 + 4 = 12.  

The probability of picking a green marble is 3/12, since there are 3 green marbles possible to grab and 12 total.  3/12 can be reduced to 1/4, or .25.  Devon has a 25% chance of picking a green marble.

Step-by-step explanation:

----------------------------------

1)

Fact :: Reason

∠DCE = 90° :: sin ∠EDC = sin 30° = 1/2 = 8/16 = CE/DE

∠ACB = 90° :: ∠DCE and ∠ACB are vertical angles

∠ABC = 60° :: 180 - ∠CAB - ∠ACB = 60°

∠CED = 60° :: 180 - ∠EDC - ∠DCE = 60°

△CDE ⁓ △ABC :: Same angles (AAA)

2)

Let's solve for AB

sin 30° = 1/2

sin 30° = BC/AB = 15/AB

1/2 = 15/AB ⇒ AB = 30

AB = 30 in

Let's solve for AC (using another way)

AC/12 = 15/8

AC = 12 * 15 / 8   = 22.5

AC = 22.5 in
