Which expression is equivalent to the one shown?2.75x + 0.25(x + 4) – (x – 3.8)

A 2x + 4.8
B 2x – 2.8
C 2x + 13.8
D 4x + 4.8

Answer:

30

Step-by-step explanation:

Answer:

a = -6, b = 48

Step-by-step explanation:

a(3x - 8) = b - 18x --> 3ax - 8a = b - 18x, then comparing two sides for the x part, only 3ax and -18x has x, so there are equivalent 3ax = -18x, solve for a = -6, then the part left is -8a = b, let a = -6 into the equation, get -8 * -6 = b = 48.

If c varies directly as l and inversely as a, then which of the equations describe the relationship among the three variables c, l and a is  [tex]\rm c = k \dfrac{l}{a}[/tex].

Given ;

c varies directly as l and inversely as a.

The following steps can be used to determine the equation that describes the relationship among the three variables c, l, and a:

Step 1 - According to the given data, 'c' is directly varying as 'l'.

[tex]\rm c\; \alpha \; l[/tex]

Step 2 - Also given in the data that 'c' is inversely varying with 'a'.

[tex]\rm c \; \alpha \; \dfrac{1}{a}[/tex]

Step 3 - Combine the expression obtained in steps 1 and 2, that is:

[tex]\rm c\;\alpha \; \dfrac{l}{a}[/tex]

Step 4 - The mathematical expression of the above conclusion is given by:

[tex]\rm c = k \dfrac{l}{a}[/tex]

where k is the proportionality constant.

So, the correct option is B).

Step-by-step explanation:

f(x)= x²-3x-8

f(-6)= (-6)²-3(-6)-8

=36+18-8

= 46

Answer:

okay i got you

x²-3x-8

now you replace every x with 6 and you have

(-6)²-3×(-6)-8

36+18-8

so f(-6)=46

Answer for A:

x = -56/31

Step-by-step explanation:

The total angle for a pentagon is 360°

100 + 20(-56/31) + 140 + 160 - 5(-56/31) + 16(-56/31) + 16 = 360

100 + -36.1290322581 + 140 + 160 + 9.03225806452 + 28.9032258065 + 16 = 360

If you copy that into a calculator you will get

360°

The inequality represented by the graph below is y > 2x - 3.

Option B is the correct answer.

An inequality is a mathematical statement that compares two expressions using an inequality symbol such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).

We have,

To graph an inequality, you need to identify the equation of the line or boundary that separates the two regions defined by the inequality.

This boundary can be a line, a curve, or even a plane in three dimensions.

Next, you need to determine which region to shade, based on whether the inequality symbol is less than (<), greater than (>), less than or equal to (≤), or greater than or equal to (≥).

If the inequality symbol is less than (<) or greater than (>), the boundary line should be drawn as a dashed line since the points on the line are not included in the solution set.

Then, shade the region above the line if the symbol is greater than (>), or below the line if the symbol is less than (<).

If the inequality symbol is less than or equal to (≤) or greater than or equal to (≥), the boundary line should be drawn as a solid line since the points on the line are included in the solution set.

Then, shade the region above the line if the symbol is greater than or equal to (≥), or below the line if the symbol is less than or equal to (≤).

Finally, label the shaded region as the solution set and write the inequality symbol next to it.

From the given graph we see that,

y > 2x - 3 has the same graph.

Thus,

The inequality represented by the graph below is y > 2x - 3.

Answer:

ladder is leaning against a building so that the distance from the ground to the top of the latter is 1 foot less than the length of the latter find the length of the latter if the distance from the bottom of the ladder to the building is 9 feet

Step-by-step explanation:

Let :

Length of ladder = l

Height = l - 1

distance from the bottom of the ladder to the building, d = 9 feets

Lenght of ladder = hypotenus

l² = height² + distance²

l² = (l - 1)² + 9²

l² = l² + 1 + 9²

l² = l² + 1 + 81

l² = l² + 82

Answer:

w = 4 ft

diagonal= 13 ft

l= 13^2-4^2=169-16 = sq root 153

=12.4 ft (approx)

Answer:

8 cubes

Step-by-step explanation:

Given

Prism

Dimension: 6 ft by 3 ft by 1 ft

Cube

Dimension: 1.5 ft by 1.5 ft by 1 ft

Required

The number of cubes in the prism

First, calculate the volume of the prism

[tex]V_1 = 6 * 3 * 1ft^3[/tex]

[tex]V_1 = 18ft^3[/tex]

Next, the volume of the cube

[tex]V_2 =1.5 * 1.5 * 1ft^3[/tex]

[tex]V_2 =2.25ft^3[/tex]

The number of cubes is calculated by dividing V1 by V2

[tex]Cubes = \frac{V_1}{V_2}[/tex]

[tex]Cubes = \frac{18}{2.25}[/tex]

[tex]Cubes = 8[/tex]
