What is a situation in which you might locate points on a coordinate grid?

Answers

Answer 1

Answer: A situation could be when you have a y=axsquared+bx+c equation. You'd find the X, or vertex, by doing x=-b divided by 2•a. Then you'd plug in x and find y. Now you have a point you can plot. To find another, you can find the y-intercept by plughing in 0 for x and finding another y.

The product of two numbers is 32. The first number, x, is one-half of the second number, y. Which system of equations can be used to find the two numbers? A. xy=32 x=1/2y B. xy=32 x=y-1/2 C. x+y=32 x=y-1/2 Dxty=32 x=1/2y

Answers

Answer:

Option A - xy=32, x=1/2y

Step-by-step explanation:

Given : The product of two numbers is 32. The first number, x, is one-half of the second number, y.

To find : Which system of equations can be used to find the two numbers.

Solution: Since, first number =x and second number = y

Situation 1 - 'The first number, x, is one-half of the second number, y'.

$\Rightarrow x=(1)/(2)y$

Situation 2 - 'The product of two numbers is 32'

$\Rightarrow x* y=xy=32$

The above two situation matches with Option A.

Therefore, Option A is correct → xy=32 x=1/2y

Solving Situation 1 and 2 we get,

Put x value in situation 2

$xy=32$

$(1)/(2)y* y=32$

$y^2=64$

$y=\pm8$

put value of y in x,

$x=(1)/(2)*(\pm8)$

$x=\pm4$

Values are → $x=\pm4$ , $y=\pm8$

X+7x+4-5x+8=12 please help meeee!

Answers

Answer:

THERE

Step-by-step explanation:

To solve the equation x + 7x + 4 - 5x + 8 = 12, we can combine like terms on both sides of the equation:

Starting with the left side of the equation:

x + 7x - 5x + 4 + 8 = 12

Combining like terms:

3x + 12 = 12

Next, we can isolate the variable by subtracting 12 from both sides of the equation:

3x + 12 - 12 = 12 - 12

Simplifying:

3x = 0

To solve for x, we divide both sides of the equation by 3:

(3x)/3 = 0/3

Simplifying further:

x = 0

Therefore, the solution to the equation x + 7x + 4 - 5x + 8 = 12 is x = 0.

Can you slove this 6=2(y+2)

Answers

Answer:

y=1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6=2(y+2)

6=(2)(y)+(2)(2)(Distribute)

6=2y+4

Step 2: Flip the equation.

2y+4=6

Step 3: Subtract 4 from both sides.

2y+4−4=6−4

2y=2

Step 4: Divide both sides by 2.

2y/2 2/2
