Answer:

x = 15

Step-by-step explanation:

Let the number be x.

(x - 14) x 3 = 3

3x - 42 = 3

3x = 45

x = 15

This is a question on forming and solving an algebraic equation. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)

The unknown number could be 15.

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given; I subtract 14 from a certain number. I multiply the result by 3. The final answer is 3 .

Let the unknown number be x.

(x - 14) x 3 = 3

3x - 42 = 3

3x = 45

x = 15

Hence, the unknown number could be 15.

Answer:

y= 10x+50

Step-by-step explanation:

x is an increasing variable so, if 10 members are joining each month, x equals 10. 50 is a non increasing number so it has no variable. and y equals all members in total, so y= 10x+50

Answer:

Y=5x

Step-by-step explanation:

Y=mx+b, or y=rise/run+starting value

as there is no starting value, we would simply add no variable

rise/run in this equation would 5/1 because when it rises 5, it goes right 1, simplifying that would be 5

Answer:

For each x, the y increases by 10 so ur equation will be y= 5x

SAS

Step-by-step explanation:

If you flip the first triangle right side up, we can see that they are congruent in the same exact spots. The two sides are congruent, as well as the angle.

Answer:

They are congurrent by SAS criterion. SAS stands for side-angle-side where the angle is in between the 2 lines. In this we can see that 2 lines have been marked as well as the angle in both triangles. SAS is a valid criterion for proving congrurency and therefore these are congurent.

Answer:

Grace jumped for 9 minutes and Zoe jumped for 12 minutes

Step-by-step explanation:

Let Grace jumped for x minutes and Zoe jumped for y minutes

Grace jump no. of times in 1 minute = 66

Grace jump no. of times in x minutes = 66x

Zoe jump no. of times in 1 minute = 56

Zoe jump no. of times in x minutes = 56x

We are given that Their jumps today and together they jump 1266 times in the total of 21 minutes

So, x+y=21  ----1

66x+56y=1266  ---2

Substitute the value of x from 1 in 2

66(21-y)+56y=1266

y=12

x+y=21

x+12=21

x=21-12

x=9

Hence Grace jumped for 9 minutes and Zoe jumped for 12 minutes

Answer:

Grace jumped for 9 minutes and Zoe jumped for 12 minutes

Step-by-step explanation:

The coordinates of reflected points are:

(a) (4, 1)

(b) (-4, -1)

Use the concept of coordinate points defined as:

A pair of numbers that describe the exact position of a point on a cartesian plane by using horizontal and vertical lines are called the coordinates.

The given points are

(4, -1)

The objective is to find the point of reflection:

(a) Along the X-axis

(b) Along the Y-axis

(a) The reflection along the X-axis,

For the point  (4, -1)

x coordinate is 4

y coordinate is -1

Keep the x coordinate the same and take the negative of the y coordinate.

Therefore,

The negative of y coordinate is -(-1) = 1

Hence,

The reflection of the point along x-axis is (4, 1).

(b) The reflection along the Y-axis:

Keep the y coordinate the same and take the negative of the x coordinate.

Therefore,

The negative of x coordinate is -(4) = -4

Hence,

The reflection of the point along y-axis is (-4, -1).

Answer:

x + 2x = 9

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

Since we are using substitution, we must replace one variable in 1 equation as the 2nd equation.

We are given:

y = 2x

x + y = 9

Here we see that y equals 2x. We can go ahead and replace in the 2nd equation y.

x + 2x = 9

And we would solve from there.

Step: Solvey=2x+6for y:

y=2x+6

Step: Substitute2x+6foryin3y=x−2:

3y=x−2

3(2x+6)=x−2

6x+18=x−2(Simplify both sides of the equation)

6x+18+−x=x−2+−x(Add -x to both sides)

5x+18=−2

5x+18+−18=−2+−18(Add -18 to both sides)

5x=−20

5x/5=−20/5

(Divide both sides by 5)

x=−4

Step: Substitute−4forxiny=2x+6:

y=2x+6

y=(2)(−4)+6

y=−2(Simplify both sides of the equation)

Answer:

x=−4 and y=−2

Answer:

y=2x

Step-by-step explanation:

compute the slope  first-

(-2,1) and (2,9)

m = 9-1/2-(-2) = 8/2+2= 8/4 = 2

knowing the slope take a given point  and substitute  it's x and y values into the equation to solve for 'b' the y-intercept-

y = mx + b,

1 = 2(-2) + b,

1 = -4+ b,

b = 5

our  equation is  y = 2x + 5

if you want an equation parallel  to the line  it  has to have the same slope. Take y = 2x

Answer: y=2x+5

Step-by-step explanation:

To find line a in slope-intercept form, we first want to find the slope. The formula for slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].

[tex]m=\frac{9-1}{2-(-2)} =\frac{8}{4}=2[/tex]

Now that we know the slope, we can plug in any point to find the y-intercept.

y=2x+b       [plug in any point]

9=2(2)+b    [multiply]

9=4+b         [subtract both sides by 4]

b=5

The final equation is y=2x+5.
