(1, -2) is the coordinates that exists on the line y = 2x - 4

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given is an equation of a line, we need to find that on which of the given points it lies,

So, we will put the points one by one, the point which stratify the equation will be the answer.

The equation :- y = 2x-4

1) (1, -2)

Put x = 1, y = -2 in the equation,

2(1)-4

= 2-4 = -2

LHS = RHS

Since, point (1, -2) satisfy the equation therefore, the line will pass through it.

Hence, (1, -2) is the coordinates that exists on the line y = 2x - 4

Answer:

where is the answer

Step-by-step explanation:

Answer:

We have to find the equation of the red line

To get the equation of the line in the slope-intercept form,

we need its slope and its y-intercept

Finding the Slope

we know that the slope of a line is the rise of the line / run of the line between 2 points

here, the 2 points are already marked on the graph

So, slope = rise / run

we notice that the line rises only 2 units and runs 8 units between the points: (-5 , 3 ) and (3 , 5)

Slope = rise  / run

now that we know the values of rise and run, we can plug the values to get the slope

Slope  = 2 / 8

Slope = 1 / 4

Finding the y-intercept

We will now look at the point (-5 , 3) , we know that the slope is 1/4.

which means that every time the line moves 1 unit to the right, it also moves 1/4 units up

So, until the point (-1 , 4), the line has finally ascended 1 unit and now is at a proper coordinate

We can see that the line is only 1 unit to the left of the y-axis, so the y-coordinate of the line after moving 1 unit to the right is the y-intercept

since the line ascends 1/4 units every time it moves 1 unit to the right,

the ordinate of the line at the y-axis will be 1/4 more than the last ordinate (which was 4)

y-intercept = (4 + 1/4)

y-intercept = 17 / 4

Equation of the line

From the question, we know that the general form of the slope-intercept form is :

y  = mx + b (where m is the slope and b is the y-intercept)

y = (1/4)x + (14/4)

y = (x + 14) / 4

Answer:

9

Step-by-step explanation:

The absolute value of any number is just its distance from 0.

-4 is 4 away from 0, so its absolute value is 4.

-5 is 5 away from 0, so its absolute value is 5.

Therefore, the equation is basically just asking what is 4 + 5, which is 9 :D.

Answer:

9

Step-by-step explanation:

The bars around the two numbers imply that it wants you to find the absolute value. Absolute value is the distance a number is from zero since distance is always positive to find the answer just make the number positive. Following this rule l-4l=4 and l-5l=5. Then add them together 4+5=9.

Answer:

(-7, 5)

Step-by-step explanation:

Since both of them are equal to y, you could just set them equal to each other.

5/7x + 4 = -1/7x - 2

6/7x = -6

x = -7

Now just plug x back to one of the equations:

y = -1/7*(-7) - 2 = 7 - 2 = 5

Therefore, the solution to the system is (-7, 5)

Answer:

Slope of line g = [tex]1\frac{1}{3}[/tex]

Step-by-step explanation:

* Mathematics rule: If two lines are perpendicular to each other, then the product of their slopes is equal to -1 .

∴ [tex]-\frac{3}{4}[/tex] × slope of line g = -1

Slope of line g = -1 ÷ [tex]-\frac{3}{4}[/tex] = 4/3 = [tex]1\frac{1}{3}[/tex]

Answer:

36

Step-by-step explanation:

4(x+7) = 6(3x)

2(x+7) = 3(3x)

2x+14 = 9x

14 = 7x

x = 2

Plugging it back into the equation:

Hexagon = 6(3*2) = 6*6 = 36

Square = 4(2+7) = 4*9 = 36

Therefore, the perimeter of each figure is 36.

-8(x+1)=-5(x+10)

-8x-8=-5x-50

-8x+42=-5x

Answer:

-8

Step-by-step explanation:

Answer:

.

Step-by-step explanation:

Use the distance formula

d = vt

where:

d = distance (miles)

v = speed (mph)

t = time (hours)

Let  x = run time

Let  y = bike time

Total time:      x + y = 4

Using these variables we can write an equation representing the formula.

dTotal = drun + dbike

49 = 9x + 22y

Next, we get the equation in terms of only x or y.  We'll get it in terms of x.

49 = 9x +22(4 - x)

49 = 9x + 88 - 22x

-39 = -13x

 3 = x

Plug in this value of x into the variables to find the distance for each part.

run distance = 9x

bike distance = 22(4 - x)
