The answer is -24.5 because...

[tex]\frac{1}{2}[/tex] = [tex]0.5[/tex]

and

[tex]-24[/tex] = [tex]-24[/tex]

Answer:

a) x = 10

b) DA = 24

c) perimeter = 110

Step-by-step explanation:

a) Since it's a parallelogram, the opposite sides are of equal length. This means that line DC = AB, so u can substitute in the values and solve for x:

DC = AB

5x - 18 = 2x + 12           (move terms so that like terms are on the same side)

5x - 2x = 12 + 18           (simplify like terms)

3x = 30                         (divide by 3 on both sides to isolate the x)

x = 10

b) now that u know the value of x, you can use it to find the length of DA. again, opposite sides are equal, so DA = BC, which means DA = 3x - 6. substitute in your known value of x and solve:

3x - 6

= 3(10) - 6

= 30 - 6

= 24

Therefore, the length of DA - 24

c) Since u know the length of DA (and therefore BC), u just have to find the length of either DC or AB and then multiply that by 2 and add it.

First, substitute in the value of x for either DC or AB (i'm gonna use AB)

2x + 12

= 2(10) + 12

= 20+12

= 32

now, to find the perimeter use this formula: 2(AB) + 2(DA)

this equals to 2(32) + 2(24) = 64+46 = 110

and that's the perimeter!

Answer:

(Base x Height)/2

Step-by-step explanation:

Think of a triangle as a square. Use the height times the base, but divide by two because a triangle is 1/2 of a square.

Answer:

In linear functions, rate of change is constant: as x goes up, y will go up a consistent amount. In exponential functions, the rate of change increases by a consistent multiplier- it will never be the same but there will be a pattern. Exponential functions are used in real world situations such as bacterial growth/decay, population growth/decline, and compound interest. Linear functions/equations can be used for comparing rates of pay. Hope this helped!

Answer:

Total number of cat and dogs = 32

Step-by-step explanation:

Missing:

Total number of puppies = 18

Puppies percent = 36%

Find:

Total number of cat and dogs

Computation:

Total number of Animals = 18 (100/36)

Total number of Animals = 50

Total number of cat and dogs = Total number of Animal - Total number of puppies

Total number of cat and dogs = 50 - 18

Total number of cat and dogs = 32

Answer:

Y= -2x + 5000

Step-by-step explanation:

The linear equation which model the situation is y = 5000 - 2x

Given:

Total water remaining in the pool = Total quantity of water in the swimming pool - (Leakage per minute × Number of minutes)

y = 5000 - (2 × x)

y = 5000 - 2x

Therefore, the linear equation which model the situation is y = 5000 - 2x

To find:

The standard form of the given quadratic equation.

Solution:

We have,

[tex]y=-5(x+2)^2-10[/tex]

Using the formula [tex](a+b)^2=a^2+2ab+b^2[/tex], we get

[tex]y=-5(x^2+2(x)(2)+(2)^2)-10[/tex]

[tex]y=-5(x^2+4x+4)-10[/tex]

Using distributive property, we get

[tex]y=-5x^2-20x-20-10[/tex]

[tex]y=-5x^2-20x-30[/tex]

Therefore, the standard form of the given equation is [tex]y=-5x^2-20x-30[/tex].
