Solve for x in the equation below.(x – 2) = –14(x – 8)

Answers

Answer:

x =38/5

Step-by-step explanation:

(x – 2) = –14(x – 8)

Distribute

x-2 = -14x+112

Add 14x to each side

x-2+14x = -14x+14 +112

15x-2 = 112

Ad 2 to each side

15x-2+2 = 112+2

15x= 114

Divide each side by 15

15x/15 = 114/15

x=114/15

Divide top and bottom by 3

x =38/5

Answer:

x = 7.6

y = x +

Answers

Answer: y=5x + 5

Step-by-step explanation:

The standard form of an equation for a straight line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).

The slope is given as 5, so we have y = 5x + b.

To find b, enter the given point (1,10) and solve for b:

y = 5x + b

10 = 5(1) + b

b = 5

The equation of a line with slope 5 and point (1,10) is y=5x + 5.

What is a expression? What is a mathematical equation? What is Equation Modelling?

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have the following equation as -

x + 7 = 5

We can write -

x + 7 = 5

x = 5 - 7

x = - 2

Now, we have to find -

3x + 2

3(-2) + 2

- 6 + 2

- 4

Therefore, the value of (3x + 2) when (7 + x = 5) is -4.

Answer:

x = 15

y = 9

Step-by-step explanation:

( 4y + 9 ) and 15y are co - interior angles.

Sum of co - interior angles is 180,

4y + 9 + 15y = 180

4y + 15y = 180 - 9

19y = 171

y = 171 / 19

y = 9

( 6x - 15 ) and ( 4x + 15 ) are alternate exterior angles.

Alternate exterior angles are equal,

6x - 15 = 4x + 15

6x - 4x = 15 + 15

2x = 30

x = 30 / 2

x = 15

What would life be like? Write a response that describes how your life would change. As always, write in complete sentences! Busy as his life now was, Ben still found time to keep company with his former schoolfellows. He and the other boys were very fond of fishing, and spent any of their leisure hours on the margin of the mill-pond, catching flounders, perch, eels, and tom-cod, which came up thither with the tide. The place where they fished is now, probably, covered with stone-pavements and brick buildings, and thronged with people, and with vehicles of all kinds. But, at that period, it was a marshy spot on the outskirts of the town, where gulls flitted and screamed overhead, and salt meadow-grass grew under foot. On the edge of the water there was a deep bed of clay, in which the boys were forced to stand, while they caught their fish. Here they dabbled in mud and mire like a flock of ducks. "This is very uncomfortable," said Ben Franklin one day to his comrades, while they were standing mid-leg deep in the quagmire. "So it is," said the other boys. "What a pity we have no better place to stand!" If it had not been for Ben, nothing more would have been done or said about the matter. But it was not in his nature to be sensible of an inconvenience, without using his best efforts to find a remedy. So, as he and his comrades were returning from the water-side, Ben suddenly threw down his string of fish with a very determined air: "Boys," cried he, "I have thought of a scheme, which will be greatly for our benefit, and for the public benefit!" It was queer enough, to be sure, to hear this little chapthis rosy-cheeked, ten-year-old boytalking about schemes for the public benefit! Nevertheless, his companions were ready to listen, being assured that Ben's scheme, whatever it was, would be well worth their attention. They remembered how sagaciously1 he had conducted all their enterprises, ever since he had been old enough to wear small-clothes. They remembered, too, his wonderful contrivance of sailing across the mill-pond by lying flat on his back, in the water, and allowing himself to be drawn along by a paper-kite. If Ben could do that, he might certainly do anything. "What is your scheme, Ben?what is it?" cried they all. It so happened that they had now come to a spot of ground where a new house was to be built. Scattered round about lay a great many large stones, which were to be used for the cellar and foundation. Ben mounted upon the highest of these stones, so that he might speak with the more authority. "You know, lads," said he, "what a plague it is, to be forced to stand in the quagmire yonderover shoes and stockings (if we wear any) in mud and water. See! I am bedaubed to the knees of my small-clothes, and you are all in the same pickle. Unless we can find some remedy for this evil, our fishing-business must be entirely given up. And, surely, this would be a terrible misfortune!" "That it would!that it would!" said his comrades, sorrowfully. "Now I propose," continued Master Benjamin, "that we build a wharf, for the purpose of carrying on our fisheries. You see these stones. The workmen mean to use them for the underpinning of a house; but that would be for only one man's advantage. My plan is to take these same stones, and carry them to the edge of the water and build a wharf with them. This will not only enable us to carry on the fishing business with comfort, and to better advantage, but it will likewise be a great convenience to boats passing up and down the stream. Thus, instead of one man, fifty, or a hundred, or a thousand, besides ourselves, may be benefited by these stones. What say you, lads?shall we build the wharf?" Ben's proposal was received with one of those uproarious shouts, wherewith boys usually express their delight at whatever completely suits their views. Nobody thought of questioning the right and justice of building a wharf, with stones that belonged to another person. "Hurrah, hurrah!" shouted they. "Let's set about it!"There is enough information in the passage to show that Hawthorne depicts Franklin as A. a determined fisher. B. a busy person. C. a problem solver.
