What is the solution to this system of linear equations?

y − x = 6

y + x = −10

A. (−2, −8)
B. (−8, −2)
C. (6, −10)
D. (−10, 6)

Thank you if you can help me!

Answers

Answer 1
It’s B
If y-x=6
Y +X =_10
then y= 6 + x, instead of y insert this no
6+ x+ x =-10
6 + 2x =-10 then collect like terms
2x =-10-6
2x=-16 then multiple both side by 1/2
X=-8
Y=6+x instead of x insert -8
Y=6-8
=-2

A sequence has the recursive definition f(1)= 2/3, f(n)= f(n-1)•
3/2 for n > 2

Write the first 5 terms of the sequence. Keep the answers as fractions.

Answers

Answer:

Explanation:

f(3) = (3 - 1) • 3/2
f(3) = 2 • 3/2
f(3) = 3

f(4) = (4 - 1) • 3/2
f(4) = 3 • 3/2
f(4) = 9/2

f(5) = (5-1) • 3/2
f(5) = 4 • 3/2
f(5) = 6

f(6) = (6-1) • 3/2
f(6) = 5 • 3/2
f(6) = 15/2

f(7) = (7-1) • 3/2
f(7) = 6 • 3/2

Answer:

What is an y-intercept ?

A y-intercept is in analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x= 0.

The difference between six, and a number divided by four is sixteen

Answers

Answer:

'The difference between six, and a number divided by four is sixteen' will be translated into an equation such as:

[tex]\frac{6\:-\:x}{4}=16[/tex]

Step-by-step explanation:

Let 'n' be the number

The difference between six and a number 'n' is written in an algebraic expression such as:

[tex]6 - x[/tex]

[tex]6-x[/tex] is obtained by 'subtracting, starting with 6'.

Dividing 6-x by 4 will become:

[tex]\frac{6\:-\:x}{4}[/tex]

so the sentence the difference between six, and a number divided by four is sixteen will become:

[tex]\frac{6\:-\:x}{4}=16[/tex]

Therefore, 'The difference between six, and a number divided by four is sixteen' will be translated into an equation such as:

Answers

See Explanation

Step-by-step explanation:

The question has unclear information.

So, I'll answer from scratch

Given

ABC = Right angled triangle

DB bisects ABC

Required

Prove that CBD = 45

From the question, we have that:

ABC is right angled at B

So, when DB bisects ABC, it means that DB divides ABC into two equal angles.

i.e.

[tex]CBD = ABD[/tex]

and

[tex]CBD + ABD = 90[/tex]

Substitute CBD for ABD in [tex]CBD + ABD = 90[/tex]

[tex]CBD + CBD = 90[/tex]

[tex]2CBD = 90[/tex]

Divide both sides by 2

[tex]\frac{2CBD}{2} = \frac{90}{2}[/tex]

[tex]CBD = \frac{90}{2}[/tex]

[tex]CBD = 45[/tex]

Hence, it is proved that [tex]CBD = 45[/tex]

Answer:

  6x^2 +64x yd²

Step-by-step explanation:

The total horizontal width is ...

  w = (x -2) +(3x) = 4x -2 . . . yards

So, the width of the downward-extending leg at right is ...

  (4x -2) -(2x -2) = 2x

The total vertical height is ...

  10 yds + 40 yds = 50 yds

So, the height of the downward-extending leg at right is ...

  50 -3x . . . yards

__

Then the empty rectangle at upper right has an area of ...

  A = LW = (3x yds)(10 yds) = 30x yd²

and the empty rectangle at lower left has an area of ...

  A = LW = (2x -2 yds)(50 -3x yds) = -6x^2 +106x -100 yd²

__

The total area is the product of overall width and overall height, less the areas of the two empty rectangles:

  A = (4x -2 yds)(50 yds) -30x yd² -(-6x^2 +106x -100) yd²

  A = 6x^2 +64x yd² . . . . . area of the proposed parking lot

The cost in dollars, y, to participate x days in a bike tour is a linear function. Lin's bike tour is described by the equation y = 5x + 50. The cost of Max's bike tour is $120 for a 14-day bike tour. If both Lin and Max take 14-day tours, whose bike tour costs less? Lin Max They cost the same amount

Answers

Answer:

They cost the same amount

Step-by-step explanation:

Given

Lin: [tex]y = 5x +50[/tex] where x = 14

Max: [tex]\$120[/tex] for 14 days

Required

Which is less expensive?

Max charges has been given from the question as; $120 for 14 days.

To determine Lin's, we simply substitute 14 for x in [tex]y = 5x +50[/tex]

[tex]y = 5 * 14 + 50[/tex]

[tex]y = 70 + 50[/tex]

[tex]y =120[/tex]

The above result of y shows that Max charges for 14 days is also $120.

Hence, they (Lin and Max) cost the same because they both equal to $120 for 14 days

A number increased by 15 is greater than 124. find the smallest integer that satisfies the inequality,

Answers

Answer:

This description translated into an inequality is

x + 15 > 124

x > 109

X is greater than 109

This means that the smallest integer that satisfies this inequality is 110 because X cannot be 109 or less; it is greater than 109.

We did not say 109.1 or 109.2 or 109.99 because it is asking for an integer, which cannot be a decimal.

Answer is 110

The dependent variable (200,300,400) are considered to be the range

Step-by-step explanation:

The computation is shown below:

As we know that

1 m = 100 cm

So

2 m = 200 cm

3 m = 300 cm

4 m = 400 cm

The function rule be 100 × x

The independent variables i.e. (2, 3, and 4) are considered to be the domain

The dependent variable (200,300,400) are considered to be the range

If 4(r + 2) – 13 = 11, what is the value of r?

Answers

Answer:

r = 4

Step by step explanation :

Step 1 : Add 13 to both sides.

4(r + 2) - 13 + 13 = 11 + 13

4(r + 2) = 24

Step 2 : Divide by 4 on both sides.

[tex]\frac{4(r+2)}{4} = \frac{24}{4}[/tex]

r + 2 = 6

Step 3 : Subtract 2 from both sides.

r = 4

The value of r is 4 in the given expression and this can be determined by using the arithmetic operation.

Given :

Expression -  4(r + 2) – 13 = 11

The following steps can be used to evaluate the given expression:

Step 1 - Write the expression.

4(r + 2) – 13 = 11

Step 2 - Add 13 on both sides in the above equation.

4(r + 2) – 13 + 13 = 11 + 13

4(r + 2)  = 24

Step 3 - Multiply 4 by (r + 2) in the above expression.

4r + 8 = 24

Step 4 - Subtract 8 on both sides in the above expression.

4r + 8 - 8 = 24 - 8

4r = 16

Step 5 - Divide 4 on both sides in the above equation.

r = 4

The value of r is 4.

did Marco buy?
HELP

Answers

Answer:

5 Hamburgers  = $12.50 4 Chicken sandwiches $8.00( $12.50 + $8.00 = $20.50

Step-by-step explanation:

Answer:

Marco bought 5 hamburgers and 4 chicken sandwiches.

Step-by-step explanation:

Set up a system of equations:

2c + 2.5h = 20.5

c + h = 9

Solve by elimination by multiplying the bottom equation by -2:

2c + 2.5h = 20.5

-2c - 2h = -18

Add the equations together and solve for h:

0.5h = 2.5

h = 5

So, he bought 5 hamburgers. Plug in 5 as h into the second equation to solve for c:

c + h = 9

c + 5 = 9

c = 4

So, Marco bought 5 hamburgers and 4 chicken sandwiches.

ITS EASYRead the following passage carefully and answer the questions given below:i. Polythene shopping bags and wrappers are a potential threat to urban environment. Once you have discarded them after use, you do not lose your link with them. They return to you in a variety of ways, though you do not realise it. For example, they choke your drains and provide breeding facilities to deadly germs.ii. A recent study has shown that about 250 tonnes of plastic waste come out of various colonies of major cities every day. This disrupts the sewer system, the essential arteries of city life, choke the land mass and clog the pores of the wetlands.iii. Unfortunately, even the villages and small towns are not free from this danger. Millions of people returning to their home towns everyday carry their shopping in colourful bags. This pleases their family and children, who after preserving them for a time dispose them in wells, rivers, tanks and drains. Many throw them off into the fields. They do it with a sense of pride, to show off. When their neighbours see that their men from the cities regularly send them those good things of life, they are impressed.iv. All over the world the worst offenders are the upper income groups of the so-called posh colonies. Though educated, the residents of these affluent areas are unaware of the damage done by the plastic bags. Millions of children in schools carry their lunch boxes in plastic bags. They callously throw them away and cause an unhealthy environment.v. As it is convenient for mothers to wrap the food in plastic, it is difficult to persuade them against doing this.
