The system of equations can be solved using linear combination to eliminate one of the variables.

2x − y = −4 → 10x − 5y = −20
3x + 5y = 59 → 3x + 5y = 59
13x = 39
Which equation can replace 3x + 5y = 59 in the original system and still produce the same solution?

2x – y = –4
10x – 5y = –20
7x = 39
13x = 39

The slope of the line whose equation is y - 4 = (x - 2) is,

⇒ m = 1

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Equation of line is,

⇒ y - 4 = x - 2

Now, We can simplify for slope as;

⇒ y - 4 = x - 2

⇒ y = x + 2

⇒ dy/dx = 1

⇒ m = 1

Thus, The slope of the line whose equation is y - 4 = (x - 2) is,

⇒ m = 1

Step-by-step explanation:

4x-3x-12=7

x-12=7

x=7+12

x=19

Answer:

x=19

Step-by-step explanation:

first you would distribute the -3 to the x and the 4 which would give you

4x-3x-12=7

next you would combine like terms (there's always an invisible 1 one front of a variable)

x-12=7

then to get the variable by itself you would add 12 on each side

x=19

Answer:

y+2=6x+2

Step-by-step explanation:

[tex]y+2=2(3x+1)\\y+2=6x+2\\y=6x+2-2\\y=6x[/tex]

Since the exponent/degree of x and y both the variables are 1 the equation is linear and y=6x represents a proportional relationship between x and y

Answer:

The slope of a line is a measure of its steepness. In math, slope is calculated as "rise over run" (change in y divided by change in x).

The kite is approximately 345 feet above the ground.

The height of the kite above the ground is 287 ft

The length of the string, the height of the kite (h) above ground and the perpendicular distance from the end of the kite string to the man forms a right angled triangle.

Trigonometric shows the relationship between the lengths and angles of a right angled triangle.

Therefore using trigonometric ratios:

sin(55) = h / 350

h = 287 ft

Therefore the height of the kite above the ground is 287 ft.

Step-by-step explanation:

well you need to multiply 1/4*114 and that should give you your answer

which would be 28.5

By simplifying the given equation, we can see that the ratio a:b is:

8:1

We start with the equation:

(a + 3b)/5 = (a - 2b)/2

The first thing we need to isolate each variable in one side of the equation.

(a + 3b)/5 = (a - 2b)/2

2*(a + 3b) = 5*(a - 2b)

2a + 6b = 5a - 10b

6b + 10b = 5a - 2a

16b = 2a

So, 16 times b is equal to 2a

We can write this as:

b/2 = a/16

b = a/8

Then the ratio a to b is:

8:1

3.75

Water flows through a pipe at a rate of 3.75 fluid quarts per minute.

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

Water flows through a pipe at a rate of 2 fluid ounces per second.

2 ounces = 0.0625 quarts

And 1 second = 0.0166667 minutes

So, water flows through a pipe at a rate of 0.0625 quarts per 0.0166667 minutes.

Water flows through a pipe at a rate of 3.75 fluid quarts per minute.

Therefore, the rate is  3.75 fluid quarts per minute.

5 video games bought.

Explanation:

Step one) identify all variables.

> y = money in bank acc AFTER buying (x) video games.

Step two) y = $40

Step three) substitute

> 40 = 90 - 10x.

Step Four) solve for x

> subtract 90 both sides.

-50 = -10x

DIVIDE by -10 on both sides ( to isolated x)

This equals 5 = x

x is number of video games bought meaning >> 5 video games bought
