What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

We have to given the function is,

3 (x - 2) - 4 (x + 1) = -22

Now, We can solve the expression as,

3 (x - 2) - 4 (x + 1) = -22

Use Multiplicative property;

3x - 6 - 4x - 4 = -22

Use addition and subtraction property,

- x - 10 = - 22

Use addition property and Add 22 both sides;

- x - 10 + 22 = - 22 + 22

- x + 12 = 0

Use subtraction property, Subtract 12 both sides;

- x + 12 - 12 = 0 - 12

- x = - 12

Multiply by -1 in both sides,

x = 12

Therefore, The solution of the equation 3 (x - 2) - 4 (x + 1) = -22 is,

⇒ x = 12

If triangle JKL is rotated 180° clockwise, the location of J’ is: B. (6, 7).

Generally, there are different types of transformation and these include the following:

A rotation can be defined as a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.

From the graph (see attachment), we have the following data:

In Geometry, rotating a point 180° about the origin in a clockwise or counterclockwise (anticlockwise) direction would produce a point that has the coordinates (-x, -y).

By applying a rotation of 180° clockwise to triangle JKL, the location of J’ is given by:

Points at J = (-6, -7)   →  Points at J' = (-(-6), -(-7))

Points at J = (-6, -7)   →  Points at J' = (6, 7).

A. (-7, 6)

B. (6, 7)

C. (7,-6)

D. (7,6)

Answer:

  (d)  (-6, 0)

Step-by-step explanation:

Given graphed inequalities and a list of points, you want the point that is a "solution."

We assume the graphed inequalities are part of a system of two inequalities and that a "solution" is one that must satisfy both of them. Any solution point will be in the doubly-shaded area, or on the solid blue boundary next to that area.

Each of the given points is 6 units from the origin on one of the coordinate axes. The only such point that lies in the doubly-shaded area is (-6, 0) on the negative x-axis.

The point (-6, 0) is a solution.

__

Additional comment

We know the kinds of inequalities that can give rise to a graph like this, but we don't know the question for which one of these points would be a solution. That is why assumptions are necessary.

The point (0, 6), for example, could be a solution to the question, "what set of values satisfies x-y ≤ 1, but not x+y < 3?"

Step-by-step explanation:

t = number of t-shirts

n = number of notebooks

n + t = 70

5n + 11t = 500

n = 70 - t

5(70 - t) + 11t = 500

Step-by-step explanation:

The function that represents the total charge for renting a truck for a certain number of hours is c(h) = $90 + $20(h) and the value of the function for an input of 5, is $190 and this represents the total charge for a rental of 5 hours.

Given,

A truck rental company charges $90 plus $20 per hour.

Here we need to  identify a function that represents the total charge for renting a truck for a certain number of hours. And we also need to find the value of the function for an input of 5.

The problem statement tells you the total charge is the sum of $90 and a charge of $20 per hour. That is, for h hours, the total charge is ...

c = 90 + 20h

In functional form, this is

c(h) = 90 +20(h) . . . . . . total charger for a rental of h hours

The function value with an input of 5 is ...

c(5) = 90 +20(5)

c(5) = 90 + 100

c(5) = 290

Since the input is the number of hours of rental, and the function value is the total charge, this represents the total charge for a rental of 5 hours.

Answer: Q=Er^2/k ==> 1st option

g=4lπ^2/T^2 ==> 4th option

C=AJs^3/(km^2) ==> 2nd option

A=Fl/(Gx) ==> 4th option

w=m/(plh) ==> 1st option

Step-by-step explanation:

1. E=kQ/r^2

E*r^2=r^2 * kQ/r^2

Er^2=kQ

Er^2/k=kQ/k

kQ/k=Er^2/k

Q=Er^2/k

2. l=gT^2/(4π^2)

l*4π^2=gT^2/(4π^2) * 4π^2

4lπ^2=gT^2

4lπ^2/T^2=gT^2/T^2

g=4lπ^2/T^2

3. s^3=kCm^2/(AJ)

AJ*s^3=kCm^2/(AJ) * AJ

1/p=lwh/m

m*1/p=m*lwh/m

m/p=lwh

The area of the triangle is 6√3 units.

given that the altitude to the hypotenuse of a triangle with angles of 30 and 60 degrees is 3 units.

The hypotenuse of a triangle with angles of 30°, 60°, and 90° is always twice as long as the side opposite the 30° angle, and it is almost three times as long as the side opposite the 60° angle.

so, let the shorter side of triangle is x.

the longer side of triangle is x√3.

the hypotenuse of the triangle is 2x.

now find the value of side of triangle

[tex]x \sqrt{3} = 3 \\ \frac{x \sqrt{3} }{ \sqrt{3} } = \frac{3}{ \sqrt{3} } \\ x = \frac{3 \sqrt{3} }{3} \\ x = \sqrt{3} [/tex]

so, the length of shorter side is √3 units.

now, find the value of hypotenuse of triangle

2x = 2√3

so, the length of hypotenuse of the triangle is 2√3 units.

now, find the base of the triangle

base = a√3 = (2√3) (√3) = 2(3) = 6

base = 6 units.

now, find the area of triangle

formula 1/2 (base)(height)

A = 1/2 (6) (2√3)

A = 6√3

Hence,the area of the triangle is 6√3 units.

the answer is 1.5

Answer: Incorrect.

Step-by-step explanation: 24 out of 30 is 80.00%.

Step 1: We make the assumption that 30 is 100 % since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100 % = 30.

Step 4: In the same vein, x % = 24 .

Step 5: This gives us a pair of simple equations:

100 % = 30(1).

x % = 24(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100 % / x % = 30/24

Step 7: Taking the inverse (or reciprocal) of both sides yields

x/100 = 24/30

x = 80 %

The coordinates of the missing endpoint are (11 / 3, 14).

Herein we find the coordinates of a endpoint and a midpoint of a line segment and the location of missing endpoint can be found by using the midpoint formula, whose definition is shown:

B(x, y) = 0.5 · A(x, y) + 0.5 · C(x, y)           (1)

If we know that B(x, y) = (8 / 3, 4) and C(x, y) = (5 / 3, - 6), then the location of the missing endpoint is:

(8 / 3, 4) = 0.5 · A(x, y) + 0.5 · (5 / 3, - 6)

(16 / 3, 8) = A(x, y) + (5 / 3, - 6)

A(x, y) = (16 / 3, 8) - (5 / 3, - 6)

A(x, y) = (11 / 3, 14)
