Answers

4,6 would be the correct answer

(A) (4, 6)

Step-by-step explanation:

Since the 2nd stage light is above P, then its x-coordinate is also the same as that of P, which is 4. We know that there are 2 units per grid and since the 2nd stage is 8 units above P, the conversion to the number of grids is

[tex]8\:\text{units}×\dfrac{1\:\text{grid}}{2\:\text{units}} = 4\:\text{grids}[/tex]

So count 4 grids above the location of P, which is (4, -2) and you will get the coordinate (4, 6).

Gina wants to solve the following proportion.


a / 5/8 = 3/5 / 2/3


A. explain how to solve the problem.

B. solve the proportion. show your work.

Answers

Step-by-step explanation:

please don't understand the question. will be happy if you take a shot of it.

Thanks

a/5/8 = 3/5 / 2/3

We can take the reciprocal of the denominator, since the denominator itself is a fraction

The above equation can be rephrased as,
(a) / (5/8) = (3/5) / (2/3)

Taking reciprocal

8a / 5 = 3*3 / 5*2

8a / 5 = 9 / 5*2

a = 9 * 5 / 5*2*8

5’s get canceled, 2 and 8 gets multiplied in the denominator.

We will then be left with,

a = 9 / 16

HELP PLEASE! Write an equation with variables on both sides that has a single solution "-1." Explain how to find that solution

Answers

ANSWER : HEY MATE

The solution to the equation 2x + 3 = x + 2, where x = -1, is found by isolating the variable "x" and simplifying the equation step by step

Let's create an equation with variables on both sides that has a single solution of "-1."

Let's call the variable "x."

An equation that meets these criteria is:

2x + 3 = x + 2.

We want to isolate the variable "x" on one side of the equation to find the solution.

Start by simplifying both sides of the equation.

On the left side, we have; 2x + 3;

And, on the right side, we have x + 2.

Now solve the equation as;

2x + 3 = x + 2

Subtract x on both sides;

2x - x + 3 = 2

x + 3 = 2

Subtract 3 on both sides;

x = 2 - 3

x = - 1

So, the solution to the equation 2x + 3 = x + 2, where x = -1, is found by isolating the variable "x" and simplifying the equation step by step.

Fergus has 3 1/4 cups of oats

= 13/4 cups of oats

Oatmeal bars = 2 2/3

= 8/3 cups of oatmeal used

Therefore cups of oats left = 13/4 - 8/3

= 39/12 - 32/12

= 7/12 cups of oats left

She borrowed 1 cup of oats from neighbour

7/12 + 1/1

= 7/12 + 12/12

= 19/12 cups of oats

Blueberry oats muffin = 1 3/4 cups of oats

= 7/4 cups of oats

Total she will have now = 19/12-7/4

= 19/12 - 21/12

= - 2/12

= -1/6

Which means she needs 1/6 cup of oats more

Where do the slope and y-intercept show up in the tables and graphs?

Answers

Answer:

Solution: The general form of the line on a graph is y = mx+c,

where y is the coordinate of the point along the y-axis,

x is the coordinate of the point along the x-axis,

m is the slope of the line or arc tan of the angle the line makes with the x-axis, and

c is the intercept the line makes on the y-axis.

Suppose we want a line having a slope of 45º with the x-axis and passes through point P (4,6), the equation of the line is

y = mx + c

6 = tan 45 * 4 + c, or

6 = 4 + c, or

c = 6–4 = 2.
