Answer:

k = -3x

Step-by-step explanation:

To find the slope, use rise over run

I started from (0, 0)

To get to the next whole number point, you must go up (rise) 3 and go back (run) 1

Since we are going back, the slope is negative.

The rise over run is -3/1 which simplifies to -3

To find y-intercept, we look at the point when x = 0. When x = 0, y = 0 so the y-intercept is 0 (which means you don't have to include it into the equation

y = -3x or k if that's what you use

Answer:

393.70

Step-by-step explanation:

350x.04= 14 for 1st year

350+14= 364 for 1st year

364×.04= 14.56 for 2nd year

364+14.56= 368.56 for 2nd year

368.56×.04= 15.14 for 3yr

368.56+15.14= 393.70 yr 3 yrs

Answer:

The answer is 42.

Step-by-step explanation:

We start by using the Simple Interest Formula.

I=P x R x T

Key

P: Principal, R: Rate and T: Time

>P=$350

>R=4% or .04

>T= 3 (for 3 years)

Finally, multiply everything (350)(.04)(3)

| I= 42 |

Answer:

y=10x+5

Step-by-step explanation:

because if x=1 then y=10(1)+5 then 10+5 and it is 15, so it is true

Given parameters:

Number of boxes Athena bought for the party  = x

Number of cookies per box = 10

Number of cookies she brought to the party = 70

Number removed  = 2 boxes

Unknown:

Equation of the number of boxes = ?

Solution:

    1 box of cookies contains 10 cookies

If Athena, removed 2 boxes, in those two boxes, we have 20 cookies

 Total number of cookies  = 70 + 20 = 90 cookies;

So;

    x  = [tex]\frac{total number of cookies}{number of cookies per box}[/tex]

   Therefore;

                    x  = [tex]\frac{90}{10}[/tex]boxes

Answer:

the value of x is 23..

Step-by-step explanation:

(5x+4)+(2x+15) = 180. [being supplementary angle]

7x+19 = 180

7x = 180-19

x = 161÷7

x = 23

Answer:

3

Step-by-step explanation:

so you set up an equation because the sides are equal

10+x=4x+1

then you solve

10=3x+1

9=3x

x=3

Answer:

y=1.5x+1; x= -0.6

y= -0.25x-6; x= -24

Step-by-step explanation:

y=1.5x+1

0=1.5x+1 (To find x-intercept/xero, substitute y=0)

-1.5x=1

x= -2/3 or x= -0.6

y= -0.25x-6

0= -0.25x-6

0.25x= -6 (Move variables to the left-hand side and change its sign)

x= -24

Answer:

it was a incomplete question

Answer:

x<10

Step-by-step explanation:

Isolate X:

2x-8+8<12+8 = 2x<20

Then divide by 2:

2x/2<20/2 = x<10

x<10

[tex]f(x) = {x}^{2} + 7 [/tex]

[tex]y = {x}^{2} + 7 [/tex]

Subtract the sides of the equation minus 7

[tex]y - 7 = {x}^{2} [/tex]

Take the square root of both sides of the equation

[tex]x = \sqrt{y - 7} [/tex]

So ;

[tex] {f}^{ - 1}(x) = \sqrt{x - 7} [/tex]

Answer:

B multiply -6 and 3

Answer:

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

We have

[tex]m = \frac{0 - 4}{1 - - 3} = - \frac{4}{4} = - 1 \\ [/tex]

We have the final answer as

Answer:

[tex]\angle 1=39\textdegree[/tex]

Step-by-step explanation:

Remember that the sum of the interior angles of a triangle always equal 180. Therefore:

[tex]\angle 1+\angle Y+102=180[/tex]

Let's subtract 102 from both sides. This yields:

[tex]\angle 1+\angle Y=78[/tex]

Now, notice the that both ∠1 and ∠Y have exactly one arc mark.

Arc-marks denote congruence. Therefore, ∠1 and ∠Y are congruent to each other. In other words:

[tex]\angle 1=\angle Y[/tex]

So, we can substitute ∠Y for ∠1 for our equation. This yields:

[tex]\angle 1+\angle 1=78[/tex]

Combine like terms:

[tex]2\angle 1=78[/tex]

Divide both sides by 2. So, the measure of our angle is:

[tex]\angle 1=39\textdegree[/tex]

And we're done!

Yes; The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

The side lengths  8, 15, and 20 form the sides of a .triangle

In order to determine whether the length of the sides forms a triangle, we will use the theorem that states that:

Given the side lengths 8, 15 and 20

Taking the sum of any two sides;

8 + 15 = 23

Since 23 > 20 (third side), this shows that the theorem is true

Similarly;

Also;

Since all the conditions are met, hence the side lengths form a triangle.
