Answer:

Area = 76[tex]m^{2}[/tex]

Step-by-step explanation:

you can cut into two rectangles

first one:

top and bottom sides = 4m

two sides = 9m

Area = b*h = 9m * 4m = 36 [tex]m^{2}[/tex]

second one

top and bottom sides = 8m

two sides = 14m - 9m = 5m

Area = b*h = 8m * 5m = 40[tex]m^{2}[/tex]

Now add both rectangle areas for the total shaded Area = 36 + 40 = 76[tex]m^{2}[/tex]

Answer:

Step-by-step explanation:

-3x + 4y = -20

y = x - 4

Put the second equation into the first equation in place of y.

-3x + 4 (x - 4) = -20

Multiply everything in the parenthesis by 4.

-3x + 4x - 16 = -20

Combine like terms.

x - 16 = -20

Add 16 to both sides.

x = -4

Put this into the second equation in place of x.

y = -4 - 4

y = -8

Your solution set is (-4,-8).

Hope this helps!

Answer:

  62, 64, 66

Step-by-step explanation:

I like to work "consecutive integer" problems by considering the average, or middle value. If we call that x, then the problem statement tells us ...

  (x -2) +(x +2) = 128

  2x = 128 . . . . . collect terms

  x = 64 . . . . . . . divide by 2

The middle integer is 64, so the three even integers are 62, 64, 66.

I'm very sorry but i don't know the answer to this queshtion

Answer:

im assuming slope : 5/4 is slope

Step-by-step explanation:

the formula (y₂ - y₁) / (x₂ - x₁) is how you get slope. plug stuff in and you get (9 - 4) / (8 - 4) and thats 5/4

y=1.25x-1

Answer:

for question 7 : I think it is no

Step-by-step explanation:

if you plot the points on a quick rough sketch you will find that none of the coordinates are on the same line (which they would have to be for a straight line). No points in those 3 coordinates are the same so the there cannot be two points on the same x or y coordiante therefore there is no right-angles triangle.

If you plot the points roughly there will not be two perpendicular lines so there is no right-angles triangle.

sorry I realise   this is confusing :(

Also for Question 5:

Parallel should be anything y= for example, y=6

Perpendicular should be anything x= for example x=6 as y=7 is a horizontal line and x=6 is a vertical line. Y=6 would be parallel because y=(any number with no gradient e.g. 1,2,3,4,etc.) is horizontal.

Answer: False

Step-by-step explanation:

To see if (-2,0) is a solution to the given equation, we can plug in the point and solve. If we get the same answer, then it is a solution.

2(-2)-3(0)=6            [multiply]

-4-0=6                     [subtract]

-4≠6

Now, the doesn't equal sign tells us that -4 is not equal to 6. This means the given point is not a solution to the equation, making it false.

Question:

Sal is trying to determine which cell phone and service plan to buy for his mother. The first phone costs $100 and $55 per month for unlimited usage. The second phone costs $150 and $51 per month for unlimited usage.

The inequality that will determine the number of months, x, that are required for the second phone to be less expensive is .

The solution to the inequality is .

Sal’s mother would have to keep the second cell phone plan for at least months in order for it to be less expensive.

Answer:

a. [tex]150 + 51x < 100 + 55x[/tex]

b. [tex]x > 12.5[/tex]

c. At least 13 months

Step-by-step explanation:

Given

First Phone;

[tex]Cost = \$100[/tex]

[tex]Additional = \$55[/tex] (monthly)

Second Phone;

[tex]Cost = \$150[/tex]

[tex]Additional = \$51[/tex] (monthly)

Solving (a): The inequality

Represent the number of months with x

The first phone is expressed as:

[tex]100 + 55x[/tex]

The second phone is expressed as:

[tex]150 + 51x[/tex]

For the second to be less expensive that the first, the inequality is:

[tex]150 + 51x < 100 + 55x[/tex]

Solving (b): Inequality Solution

[tex]150 + 51x < 100 + 55x[/tex]

Collect Like Terms

[tex]51x-55x<100 - 150[/tex]

[tex]-4x<-50[/tex]

Solve for x

[tex]x > -50/-4[/tex]

[tex]x > 12.5[/tex]

Solving (c): Interpret the solution in (b)

[tex]x > 12.5[/tex] implies 13, 14, 15....

Hence, She'll keep the second phone for a period of at least 13 months
