The system of linear inequalities as shown in the given graph is:

y < 1/3x + 2

y ≤ -2x + 2

Depending on the inequality sign, we can express the linear inequality in slope-intercept form as, y = mx + b. The sign "=" would be placed by the appropriate inequality sign, the m represents the slope and b represents the y-intercept of the line.

One of the lines is dashed, and the shaded part is beneath it, therefore, the inequality sign for the dashed line would be "<".

For the solid line, the inequality sign to use would be "≤" because the shaded part is also beneath it.

Both lines intercept the y-axis at y = 2, therefore, the y-intercept (b) for both lines would be: b = 2.

Slope of the dashed line (m) = rise/run = 1/3

Slope of the solid line (m) = rise/run = -2/1 = -2

The inequality for the dashed line would be written by substituting m = 1/3 and b = 2 into y < mx + b:

y < 1/3x + 2

The inequality for the solid line would be written by substituting m = -2 and b = 2 into y ≤ mx + b:

y ≤ -2x + 2

The system would be:

y < 1/3x + 2

y ≤ -2x + 2

Answer:

[tex]{ \tt{f(x) = - 3x + 8}} \\ \\ { \tt{f( - 4) = - 3( - 4) + 8}} \\ \\ { \tt{f( - 4) = 12 + 8}} \\ \\ { \tt{f( - 4) = 20}}[/tex]

For the function f(x) = -3x + 8, f(-4) is 20.

Given,  f(x) = -3x + 8 and f(-4)

Put the value -4, wherever x is present,

f(x) = -3x + 8

f(-4) = (-3 × -4) + 8

f(-4) = 12 + 8

f(-4) = 20

∴ The value of f(-4) is 20 for function f(x) = -3x + 8

Answer:

20

Step-by-step explanation

We need to find the multiples of 10 and 20 (multiples of 10 = 10, 20, 30, 40; multiples of 20 = 20, 40, 60, 80) and choose the smallest multiple that is exactly divisible by 10 and 20, i.e., 20.

Answer:

20

Step-by-step explanation:

First, find the factors of both 10 and 20

Factors of 10: 1, 2, 5, 10

Factors of 20: 1, 2, 4, 5, 10, 20

Notice any common factors?: 1, 2, 5, 10

Now multiply the greatest common factor, 10, with another even number to hopefully get 20: 10*2=20.

Hence, the least common multiple is 20.

The equation of the line that passes through the point (-9, 2) and is perpendicular to the line 10x - 5y = 6 is y = - 1 / 2 x - 5  /2

The equation of a line can be represented in slope intercept form.

Therefore,

y = mx + b

where

Therefore, the equation of the line is perpendicular to 10x - 5y = 6.

5y = 10x - 6

y = 2x - 6 / 5

Perpendicular lines follows the rule below:

m₁m₂ = -1

Therefore,

2m₂ = -1

m₂ = -1 / 2

The slope of the line is - 1 / 2. Now, let's find the equation of the line as it passes through (-9, 2)

y = - 1 / 2 x + b

2 = - 1 / 2 (-9) + b

2 = 9 / 2 + b

b = 2 - 9 / 2

b = 4 - 9 / 2

The new dimensions of the box are 5 feet, 4 feet, and 6 feet.

Given:

A rectangular box has dimensions of 4 feet by 3 feet by 5 feet.

So, Length = 4 feet ,width = 3 feet and height = 5 feet.

Volume of rectangular box = length × width × height

                                             = 4 × 3 × 5 = 60 feet³

Now, increasing each dimension by the same amount yields a new box.

Let the increase in dimension be x feet.

The dimensions of the new box are,

Length = (4 + x) feet ,width = (3 + x) feet and height = (5 + x) feet.

Volume of new box = length × width × height

                                 = (4 + x) (3 + x) (5 + x)

It is given that the volume of the new box is twice the volume of the old box, 2 × 60 feet³ = 120 feet³

So, equate the volume to find the value of x.

(4 + x) (3 + x) (5 + x) = 120    

(12 + 7x + x²) (5 + x) = 120

60 + 12x + 35x + 7x² + 5x² + x³ = 120

60 + 47x + 12x² + x³ = 120

x³ + 12x² + 47x - 60 = 0  

x = 1

Hence each dimension was increased by 1 foot.

Step-by-step explanation:

Since the lowest common multiple of 2 and 3 is 6, so let's find the cost of 6 bags of chips from each store.

Store A

cost for 6 bags of chips

= 3(2.5)

= $7.50

Store B

cost for 6 bags of chips

= 2(3.25)

We have the following;

Distance of the object = 125 meters

Step-by-step explanation:

If Lisa and Joey put the same amount of money every month in the savings account for David's future and the situation is plotted in a graph where time is on the x-axis, then there will be straight line with a constant slope.

As per the question statement, Lisa and Joey just became parents to their son, David and they decided to start a savings account for their newborn's future, where they agreed to put an equal amount of money every month.

We are required to determine the condition of the variables if the above-mentioned situation is plotted into graph and the account gets constantly filled with money as David grows older.

To solve this question, first let us consider the time to be plotted on the X-axis (As mentioned in question statement that "Time" is almost always on the x-axis) and the money collected to be plotted on the Y-axis.

Since, an equal amount of money is put into the account every month, therefore, taking 1 month as unit time to plot our graph, the money will grow diagonally in a straight line with a constant slope. Hence, both the variables (abscissa and ordinates) will increase on a constant ratio along the first quadrant.

EXPLANATION:

Given;

We are given a parallel pair of lines m and n, and a transversal that cuts both lines.

Required;

We are required to find the value of x.

Step-by-step solution;

When a pair of parallel lines are cut by a transversal, the angle formed by the point of intersection of one line and the transversal is equal to that formed by the other line and the transversal when they both lie on the same side of the transversal.

This means on the diagram given;

This means angle 167 on line n is equal to angle 167 on line m. These are called corresponding angles.

The same applies to angle x on the line m and the other angle on line n. They both are also corresponding angles.

Next, take note that angles that lie on either side of a vertex where two lines intersect are called vertically opposite angles (or just opposite angles).

Therefore, angle x = 167 and angle 167 = x.

The time of Trip 2 is 0.8 hours

The distance of trip 1 is 32 km

Given,

The speed of the bus = 40 km/h

Talia's walked at a speed = 5 km/h

To determine the time,x for her walk here used the equation; 40(0.9 – x) = 5x.

We have to find the time from Talia's home to bank in bus and the distance.

Here,

Equation is already given, we can simplify it and get x which is the time.

40(0.9 – x) = 5x.

36 - 40x = 5x

36 = 40x + 5x

36 = 45x

x = 36/45

x = 0.8 hours = 0.8 x 60 = 48 minutes

Now,

Distance from Talia's home to bank;
