4. Which of these points does not lie on the graph of y=-2x+7?
(A) (-1,9
(B) (4,-1)
(C) (-3,1)
(D) (-2.11)

Answers

c.) -3, 1. is the answer because when you look at the graph it’s the only one that doesn’t touch the line through the graph.

The point (-3,1) is not passing through the graph y = -2x + 7 so option (C) will be correct.

How to plot a graph?

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

Given that a line  y=-2x+7

Now in order to satisfy any point of this function then the value or

coordinate should satisfy the function or line.

So by checking option (A) 9 = -2(-1) + 7 = 9 so its satisfy.

So all options except (C) are satisfying.

Option (C) ⇒

-2(-3) + 7  ≠ 1

Hence "The point (-3,1) is not passing through the graph y = -2x + 7".

Answers

Answer:

x > 1

Step-by-step explanation:

Subtract 3 from both sides

8x + 3 - 3 > x + 10 - 3

Simplify

8x > x + 7

Subtract x from both sides

8x - x > x + 7 - x

Simplify

7x - 7

Divide both sides by 7

7x/7 > 7/7

Estimate 154 divide 7
​

Answers

Answer:

22

Step-by-step explanation:

The result of 154 divided by 7 will be 22.

What is the rule of division?

The rules of the division include easy memory tricks that make division calculations easier by generating patterns you may use to deconstruct both simple and complex situations. The guidelines establish requirements that a number must meet in order to neatly divide into another number. While some division rules only require one or two steps to evaluate a number's divisibility, others require two or three steps. Even though some of these formulas are lengthy, division rules help hasten the process of dividing huge numbers.

Remember to continue using the divide, multiply, subtract, and drop-down method for long division problems until all of the dividend's digits have been divided. The solution to the division puzzle is the quotient.

Since the given problem is not a large division. We can solve it by breaking 154 into two parts

    ______

7 / 154     \    2 2

   14

 ---------

   1 4

   14

---------

    0

Therefore, 22 will come from dividing 154 by 7.
