Answer:

23a) x=-y+9/2

23b) x=1/2 y+3/2

Step-by-step explanation:

23a:

Let's solve for x.

2x+2y=9

Step 1: Add -2y to both sides.

2x+2y+−2y=9+−2y

2x=−2y+9

Step 2: Divide both sides by 2.

2x/2 = -2y+9/2

x = -y+9/2

23b:

Let's solve for x.

2x−y=3

Step 1: Add y to both sides.

2x−y+y=3+y

2x=y+3

Step 2: Divide both sides by 2.

2x/2=y+3/2

x = 1/2 y+3/2

On selling the article there is a loss of 25% hence it is obvious value would be higher than 150. Let's take a round figure 200. Hence, the cost price is 200, on selling for a loss of Rs. 50, 25% selling price becomes Rs. 150.

Answer:

Step-by-step explanation:

Step-by-step explanation:

if BC is the diamater and angle BAC is inscribed, that means that BAC=90degrees, because the chord of the angle(BC) is equal to half a circle or 180 degrees and each inscribed angle is 1/2 of its respective chord. so angle B's value would be equal to 180-BAC-ACB=90-ACB(or angle C)

Therfore he can buy 4 pairs of shorts.

B. No, if he wanted to buy 6 pairs of shorts it would be $87.00 with the sneakers. If he wanted to buy the shorts by themselves then it would only be $48.00 WITHOUT the sneakers.

C. The most amount of shorts he can buy would be 4 WITH the sneakers.

Answer:

x = 5, x = -7

Step-by-step explanation:

If you mean find the roots, then x = 5 and x = -7

Because roots makes the equation equal to 0 and 5 - 5 = 0 and -7 + 7 = 0

Answer:

y=-3x+2

y = [tex]\frac{1}{5}[/tex]x - 5

Step-by-step explanation:

Question 1

It is given that;

- one of the lines has an equation of; y = -3x-7

- the given line's y-int is (0, 2) ~(The y-int is when the line crosses the y axis, hence x is zero)

- these two lines are parallel

When two lines are parallel, their slope is the same, hence  the equations of the given line would look like this;

y = -3x + 2

In the slope-intercept format (which is; y = mx + b, where "m" is the slope, and "b" is the y-intercept).

Questions 2

It is given that;

- one of the lines has an equation of y = -5x + 1

- the given line's y-int is (0, -5) ~(The y-int is when the line crosses the y axis, hence x is zero)

- these two lines are perpendicular

When two lines are perpendicular, their slopes are the negatives reciprocal of each other, hence the equations of the given line would look like this;

y = [tex]\frac{1}{5}[/tex]x - 5

In the slope-intercept format (which is; y = mx + b, where "m" is the slope, and "b" is the y-intercept).

Answer:

Option (1)

Step-by-step explanation:

From the triangles given in the picture,

Since, JK ≅ KL [Given]

JM ≅ ML [Given]

KM ≅ KM [Reflexive property of congruence]

ΔJMK ≅ ΔLMK [SSS property of congruence]

Therefore, ∠JKM ≅ ∠LKM [CPCTC]

(2x + 5) = (3x - 6)

3x - 2x = 5 + 6

x = 11

m∠JKL = m∠JKM + m∠LKM

            = (2x + 5) + (3x - 6)

            = 5x - 1

            = 5(11) - 1

             = 54

Option (1) will be the answer.

Answer:

C is approximately 10.3

Step-by-step explanation:

To get the length of c, we use the cosine rule

This is;

The square of the missing side is equal the sum of the squares of the other sides minus 2 multiplied by the product of the two other sides and the cos of the angle facing the missing side

We have this as;

c^2 = 7^2 + 9^2 - 2(7)(9) * Cos 79

c^2 = 49 + 81 - 126 cos 79

c^2 = 130 - 24.042

c^2 = 105.96

c = √105.96

c = 10.29 which is approximately 10.3

Answer:

7362.49 yards

Step-by-step explanation:

Mauricio has a height of 2 yards

The building has a height of 906 yards from the ground

The height of the building from Mauricio's eye will be : 906 - 2 = 904 yards

The angle of elevation of the top of building from the viewer = 7°

Apply the formula for tangent of an angle where;

Tan ∅ = Opposite side height/Adjacent length

Tan 7° = height of building / viewer distance from base of building

Tan 7° = 904 / viewer distance from base of building

Viewer distance from base of building = 904/Tan 7°

=7362.48917089

=7362.49 yards

Answer:

126 inches

Step-by-step explanation:

If your drawing is on a 1 : 40 scale, to find the scale's height, divide the ride's height by 40.

420 / 40 = 10.5

So the drawing will be 10.5 feet tall.

To convert 10.5 feet to inches, multiply it by 12.

10.5 * 12 = 126 inches

Step-by-step explanation:

slope = 4

Answer:

x=-5 and y=-3

Step-by-step explanation:

-6y+2=-4x convert this into standard form

  y=x+2

  plug in the slope intercept form in to y

  -6(x+2)+4x=-2

  -6x-12+4x=-2

  -2x-12=-2 now solve for x

  -2x-12+12=-2+12

  -2x=+10

  x=-5 now solve for y

  y=-5+2

  y=-3

  so basically x=-5 and y=-3

Answer:

Area of rectangle = [tex]\mathbf{x^2-4x}[/tex]

Perimeter of rectangle = [tex]\mathbf{4x-8}[/tex]

Step-by-step explanation:

We are given:

Length of rectangle = x

Width of rectangle = x-4

We are not given if we want to find area of rectangle or perimeter of rectangle.

So, I will be finding both

Area of rectangle

The formula used is: [tex]Area\: of\: rectangle=Length \times Width[/tex]

Putting values and finding area

[tex]Area\: of\: rectangle=Length \times Width\\Area\: of\: rectangle=x \times (x-4)\\Area\: of\: rectangle=x^2-4x[/tex]

So, we get area of rectangle = [tex]\mathbf{x^2-4x}[/tex]

Perimeter of rectangle

The formula used is: [tex]Perimeter \: of\: rectangle=2(Length+ Width)[/tex]

Putting values and finding perimeter

[tex]Perimeter \: of\: rectangle=2(Length+ Width)\\Perimeter \: of\: rectangle=2(x+ x-4)\\Perimeter \: of\: rectangle=2(2x-4)\\Perimeter \: of\: rectangle=4x-8[/tex]

So, we get perimeter of rectangle = [tex]\mathbf{4x-8}[/tex]

I hope, it can help in solving the question.

Answer:

8

Step-by-step explanation:

this 3 qub root of 512 is 8

Answer:

An arithmetic sequence has a constant difference between each term. ... A geometric sequence has a constant ratio (multiplier) between each term. An example is: 2,4,8,16,32,… So to find the next term in the sequence we would multiply the previous term by 2.
