Answer:

y=6/5x-8

Step-by-step explanation:

Hi there!

We want to find the equation of the line that passes through (5, -2) and has the slope of 6/5

We can write the equation of the line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept.

Since we are already given the slope of the line, we can immediately plug it into the equation:

y=6/5x+b

Now we need to find b

Since the equation passes through the point (5, -2), we can use it to solve for b

Substitute 5 as x and -2 as y:

-2=6/5(5)+b

Multiply

-2=6+b

Subtract 6 from both sides

-8=b

Substitute -8 as b.

y=6/5x-8

Hope this helps!

Step-by-step explanation:

-8 < -4x ≤ 12

-8/-4 < x ≤ 12/-4

2 < x ≤ -3

x ≤ -3 or x > 2

Option → A

Answer:

The unit rate is -4

Step-by-step explanation:

For each increase of 1 unit in x there is a change of -4 in y

Applying statistical concepts, it is found that the values are:

When a constant is added to each data in a variable:

When a constant is multiplied to each data in a variable:

Hence, mean of 12, added with p and multiplied with q, for a mean of 51:

[tex](12 + p)q = 51[/tex]

Variance of 84, after the operations, 756:

[tex]84\sqrt{q} =756[/tex]

[tex]\sqrt{q} = \frac{756}{84}[/tex]

[tex]\sqrt{q} = 9[/tex]

[tex](\sqrt{q})^2 = 9^2[/tex]

[tex]q = 81[/tex]

For p:

[tex](12 + p)q = 51[/tex]

[tex](12 + p)81 = 51[/tex]

[tex]12 + p = \frac{51}{81}[/tex]

[tex]12 + p = 0.63[/tex]

[tex]p = -11.37[/tex]

The resulting expression after expansion is 110x - 1200

Given the function P(x) = 140x - (30x + 1200)

To solve the literal equation, we will have to simply expand the bracket using the distributive law.

According to the law  a(b+c) = ab+ac

You can see that a was distributed over "b" and "c"

For the expression, we will distribute -1 over 30x and 1300 to have;

P(x) = 140x -(30x) - (+1200)

P(x) = 140x - 30x - 1200

P(x) = 110x - 1200

Hence the resulting expression after the expansion is 110x - 1200

Once you know the slope of the line, plug it in for m in y = mx +

Step-by-step explanation:

Answer:

Linear function, zero slope

Step-by-step explanation:

A horizontal line neither rises nor falls and has a zero slope.  Hence, the equation y = mx + b becomes y = b, where b is the y-intercept. The selected option for the equation of the given graph is correct, that y = 5.

A function is a relation where any x-coordinate cannot be paired with more than one y-coordiante.  Consequently, if a graph contains two or more different points with the same first coordinate, the graph cannot represent a function.  

A great way to test whether a given graph represents a function is by performing the vertical line test.  The vertical line test states that if each  vertical line drawn intersects the graph at exactly one point, then the relation is a function.

Attached is an edited screenshot of the given graph, showing the results of the vertical line test. The given graph is a function since each vertical line crosses the graph at most once.  This implies that each x-coordinate corresponds to exactly one y-coordinate.

Therefore, the given graph represents a linear function with a zero slope.

Answer:6.27

Step-by-step explanation: 22.8 increased by 27.5%

27.5% × 22.8 = 6.27

27.5 ÷ 100 × 22.8 = 6.27

27.5 × 22.8 ÷ 100 = 6.27

627 ÷ 100 = 6.27

Answer:

Since both equations equal to f(x), you can set 4x+11 equal to -1 and solve for x.

4x+11=-1

Subtract 11 from both sides.

4x=-12

Divide both sides by 4.

Answer:

The shortest distance from a point to a line is the perpendicular from the line to the point

The equation of the given line is -x + 2·y = 14, which can be written in slope and intercept form as follows;

-x + 2·y = 14

2·y = 14 + x

y = 14/2 + x/2 = x/2 + 7

y = x/2 + 7

The slope, m₁ = 1/2 and the y-intercept = 7

Therefore, the slope, m₂, of the perpendicular line to the line -x + 2·y = 14 which was rewritten as y = x/2 + 7 is m₂ = -1/m₁ = -1/(1/2) = -2

Therefore, we have that the slope of the line from A(-1/4, 5) to the line -x + 2·y = 14, is -2

The equation of the line is therefore;

y - 5 = -2(x - (-1/4))

y - 5 = -2·x - 1/2

y = -2·x - 1/2 + 5 = -2·x + 9/2

y = -2·x + 9/2

The coordinates of the point on the line -x + 2·y = 14 (y = x/2 + 7) that coincides with the perpendicular from the point A(-1/4, 5) is therefore given as follows;

-2·x + 9/2 = x/2 + 7

9/2 - 7= x/2 + 2·x

-2.5 = 2.5·x

x = -2.5/2.5 = -1

x = -1

y = x/2 + 7 = -1/2 + 7 = 6.5

y = 6.5

The coordinates of the point on the line -x + 2·y = 14 (y = x/2 + 7) that coincides with the perpendicular from the point A(-1/4, 5) is (-1, 6.5)

The distance from A(-1/4, 5) to B(-1, 6.5), is given as follows;

Where;

(x₁, y₁) = (-1/4, 5), and (x₂, y₂) = B(-1, 6.5)

Plugging in the values, we have;

Therefore, the distance from A(-1/4, 5) to the line -x + 2·y = 14 ≈ 1.7 units, rounding to the nearest tenth.

The linear term is the term with a degree of 1, hence the coefficient of the linear term is -11

Given the functions (3x-2) (2x^2 + 7x-1)

Taking the product of the functions will give:

(3x-2) (2x^2 + 7x-1) = 3x(2x^2) + 3x(7x) + 3x - 4x^2 - 14x + 2

(3x-2) (2x^2 + 7x-1) = 6x^3+21x^2 -11x - 4x^2 + 2

(3x-2) (2x^2 + 7x-1) =6x^3+17x^2 - 11x + 2

The linear term is the term with a degree of 1, hence the coefficient of the linear term is -11
