PLEASE HELP! DUE TOMORROWWrite each equation in standard form.

y - 4 = -3(x - 3)

and

y + 9= 2(x + 5)

Answers

Answer 1
Answer: I think you do not want to find the value of x and y from the two given equations. Only thing you want is to write the equations in their standard form only. Let us take one equation at a time and then write them in their standard form.
In case of the first equation:
y - 4 = - 3(x - 3)
y - 4 = - 3x + 9
3x + y = 9 + 4
3x + y = 13
Now we take the second equation
y + 9 = 2(x + 5)
y + 9 = 2x + 10
2x - y = 9 - 10
2x - y = -1
These are the two standard form of the given equations.
Answer 2
Answer: For the first equation...
y-4 = -3x+9 \n 3x+y = 13

For the second equation...
y+9 = 2x+10 \n -2x+y = 1 \n 2x -y = -1

If this helped, please consider making this the brainliest answer! :)

The formula for the area of a ∆ is 1/2bh. So since you already have the area, solve for x.
24=(1)/(2)(8)x
24=4x
6=x

What expression represents five time the quotient of some number and ten?A: 5 ( 10 - z )
B: 5 ( z / 10 )
C: z ( 10 / 5 )
D: 5 ( z - 10 )

Answers

Answer: B

Step-by-step explanation:

First off, choices A and D can be elimination because you are not subtracting. In choice C, we have 10 divided by 5 as opposed to z divided by 5. The answer is B.

What is the area of the shaded region to the nearest tenth of a foot?Part a) Explain what formulas you will use to find the area of the shaded area.

Par b) Explain how you find the area of the shaded region. What was your thought process?

Answers

a) The shaded region is that portion of the rectangle that is not in the circle. You need the formulas for the area of a rectangle and a circle.
 Area of rectangle = length*width
 Area of circle = (π/4)*diameter²

b) The figure shows the width of the rectangle is 14 ft, the same as the diameter of the circle. The length of the rectangle is shows as 21 ft. The shaded area is the difference ...
 Shaded Area = Area of rectangle - Area of circle
 Shaded Area = (21 ft)*(14 ft) - (π/4)*(14 ft)²
Evaluating this expression, we have
 Shaded Area ≈ 294 ft² - 153.9 ft² = 140.1 ft²

A bag holds 6 tiles: 2 lettered and 4 numbered. Without looking, you choose a tile. What is the probability of drawing a number?

Answers

The bag contains 6 tiles: 2 lettered and 4 numbered. The probability of drawing a number without looking is 2/3.

Probability is the ratio of the number of favorable outcomes and a total number of outcomes. it deals with finding out the likelihood of the occurrence of an event.

Given that,

The bag holds 6 tiles.

Among the tiles, 2 are lettered and 4 are numbered.

The task is to choose a tile from the bag without looking.

The bag contains a total of 6 tiles: 2 lettered and 4 numbered.

Therefore,

The probability of drawing a number can be calculated by dividing the number of numbered tiles by the total number of tiles.

Probability of drawing a number = (Number of numbered tiles) / (Total number of tiles)

Probability of drawing a number = 4 / 6

Simplifying this fraction, we get:

Probability of drawing a number = 2 / 3

Hence,

The probability of drawing a number from the bag is 2/3.

you take the total number as the denominator and the amount of each become your numerators.For numbered it's 4/6 then you divide both the top and bottom number by two and you get 2/3 or 66%.
