help me please. real answers only. Write an equation for the line parallel to the given line that contains C.
C(2,8); y = - 4x + 5
y =
(Type your answer in slope-intercept form.)

Answers

Answer:

y = -4x + 16

Step-by-step explanation:

The slope of the given line is -4

when two lines are parallel, their slopes are equal

That means the slope of the second line is -4 too

Thus, we have to use the point-slope form to write the equation

That will be

y-y1 = m(x-x1)

y-8 = -4(x-2)

y -8 = -4x + 8

y = -4x + 8+8

y = -4x + 16

3n - 2n- 6h + 9

Pls help ASAP

Answers

Answer:

n-6h+9

first you subtract the ns from each other because those are the only like terms

3n-2n-6h+9

So first you get all the like terms together from calculating the addition sequence here from their coefficients

So

(3-2-6)x+9

Now you calculate the difference in the parenthesis

-5x+9 is your answer and you leave it like that because you can’t really do anything else just leave it how it is

The half-life of a radioactive kind of iodine is 60 days. How much will be left after 240 days, if you start with 480 grams of it?

Answers

Answer:

30 grams

Step-by-step explanation:

half life is 60 days so every 60 days the amount 480 grams will be half

in 240 days will decay  240 /60 = 4 times

once 480 /2 = 240

twice 240 /2 = 120

trice 120 / 2 = 60

four times 60/2 = 30 grams will be left

???????????????i didn’t learn this what’s the answer ?

Answers

Answer:

24 inches squared

Step-by-step explanation:

That is a triangle, and the area of a triangle is 1/2(b)(h), which is one half times the base times the height. Let's identify those things.

1/2: the area of a rectangle can be calculated base times the height, and a triangle is half of that rectangle, hence the 1/2

(b) or base: base is usually identified as the horizontal line in the triangle, which is 6 inches in this case.

(h) or height: height is usually the vertical line, and in this case, the vertical line is 8 inches.

Now time for the math:

1/2(6)(8) = 24 inches squared

The cost for 5 adults and 3 children to attend a show is $210. ( /5)
For 2 adults and 5 children the cost is $160.
Form a pair of simultaneous linear equations and solve them to find the cost of:
i. an adult ticket
ii. a child ticket

Answers

Answer: i. Cost of adult ticket = $ 30

ii.  Cost of child ticket = $20

Step-by-step explanation:

Define variables:

Let x= cost of 1 adult tickets , y= cost of 1 child tickets.

Form linear equations:

5x+3y = 210      (i)

2x+5y= 160  (ii)

Multiply (i) by 2 and (ii) by 5

10x +6y = 420       (iii)

10x+25y = 800        (iv)

Eliminate (iii) from (iv)

19y = 380

⇒ y= 20

Put this in (i)

[tex]5x+3(20)=210\Rightarrow\ 5x+60 = 210\\\\\Rightarrow\ 5x=150\\\\\Rightarrow\ x=30[/tex]

Hence, Cost of adult ticket = $ 30 and Cost of child ticket = $20

QUICK PLZ!!! Use the number line below, where RS = 6y + 3, ST = 4y + 7, and RT = 60.​

Answers

Step-by-step explanation:

[Diagram in image attached]

RS + ST = RT

(6y +3) + (4y + 7) = 60

6y + 3 + 4y + 7 = 60

10y + 10 = 60

10y = 60 - 10

10y = 50

y = 50/10

y = 5

RS = 6y +3 = 6(5) + 3 = 30 + 3 = 33

ST = 4y +7 = 4(5) + 7 = 20 + 7 = 27

RT = 60

{RS + ST = RT

33 + 27 = 60}
