у = 4х – 1
у = 2х – 5
How do you solve this, by using substitution?!

Answers

Answer 1

Answer:

x = -2, y = -9

Step-by-step explanation:

You can substitute the value of y into y. The first equation shows that y is equal to 4x -1, so we can switch this with the y in the second equation.

y = 2x -5 will become

4x - 1 = 2x - 5

Add 5 to both sides

4x + 4 = 2x

Subtract 4x from both sides

4 = -2x

Divide both sides by -2

-2 = x

Now we plug this number into an equation to find y.

y = 4x - 1 becomes

y = 4(-2) - 1

Simplifying it, we have:

y = -8 - 1

y = -9

Ann and Ruth bowled together and had a combined score of 410 points. Ann's score was 44 points less than Ruth's score. Write a system of equations that can be used to determine x, Ann's score and y, Ruth's score.

Answers

Answer:

x=y-44 and x+y=410

Step-by-step explanation:

So, you want to use the equations x=y-44 and  x+y=410 when x is Ann's score and y is Ruth's score. This is because x (Ann's score) is Ruth's score (y) but 44 less, so you subtract y-44 to get x. Then x+y would also have to equal 410 so that's the other equation. Graphing the 2 equations gets you to the point  (183,227) in which Ann's score is 183 points and Ruth's score is 227 points.

A man is walking 3 miles per hour toward point B

from point A. At the same time, a woman is

running 6 miles per hour toward point A from

point B. If point A and point B are 15 miles apart,

how far from point B will they meet?

E. 5 miles

F. 6 miles

G. 9 miles

H. 10 miles
PLEASE PLEASE HELP I NEED THIS ANSWER

Answers

Answer:

6 miles

Step-by-step explanation:

because the common denominator is 12 so the man will walk 12 miles in 4 hours and the woman will walk 12 miles in 2 hours so they will meet in the middle

If point A and point B are 15 miles apart, they will meet H) 10 miles from point B.

The answer to the question is H: 10 miles.

To solve this problem, we can use the concept of relative velocity. Relative velocity is the velocity of one object as seen by another object. In this case, the man and the woman are moving towards each other, so their relative velocity is the sum of their individual velocities.

The man's velocity is 3 miles per hour and the woman's velocity is 6 miles per hour, so their relative velocity is 3 + 6 = 9 miles per hour.

We know that point A and point B are 15 miles apart, so they will meet when the distance between them is 0. The time it takes them to meet is 15 / 9 = 5/3 hours.

In 5/3 hours, the man will travel 3 * 5/3 = 5 miles and the woman will travel 6 * 5/3 = 10 miles. Therefore, they will meet 10 miles from point B.

Answers

Answer:

98 - 24√3 is your answer dear.

Step-by-step explanation:

Let the length of broken part of the tree = 14 - x

For finding x

sin60° = √3/2 = x /14-x

14√3 - √3x = 2x

14√3 = 2x + √3x

14√3 = (2 + √3)x

x = 14√3/(2 + √3)x

after rationalisation

x = 24√3 - 84

substract it 14 - (24√3 - 84)

Write an equation of the line that passes through (3, 7) and is parallel to the line shown. (1, 4) (- 2, - 2)

Answers

Answer:

y=2x+1.

Step-by-step explanation:

You first need to find the slope of the line already graphed. -2 to 1 would be three units to the right, and -2 to 4 would be six units up. You would use the equation (y2-y1)/(x2-x1), where x1 and y1 would be the x and y values of the first coordinate of the graphed line, and x2 and y2 would be the second coordinate. This would be 6/3, which can be simplified to 2/1, which can be simplified to 2, which would mean the slope of the given line would be 2, as well as the parallel line. Now, you could use a pretty complicated equation to find the y-intercept of the line you need to graph, but I would recommend using the slope to find it. Since the given point is (3, 7), you would need to go to the left, meaning you would reverse the slope until you reach the y-axis, so you would use -2 as the slope. 3*-2=-6, and 7-6=1, so the y-intercept would be 1. The answer would be y=2x+1. Hope this helps.

So here, 3/5 is already a fraction and 2 and 1/2 can be written as 5/2.

as multiplying by the reciprocal of that fraction.

In other words, 3/5 ÷ 5/2 can be rewritten as 3/5 · 2/5.

Finally, multiplying across the numerators and the

denominators, we have 6/25.

Freed by the Emancipation Proclamation in 1865, former slave Henry Adams testified before the U.S. Senate fifteen years later about the early days of his freedom, describing the process of sharecropping.The white men read a paper to all of us colored people telling us that we were free and could go where we pleased and work for who we pleased. The man I belonged to told me it was best to stay with him. He said, The bad white men was mad with the Negroes because they were free and they would kill you all for fun. He said, stay where we are living and we could get protection from our old masters. I told him I thought that every man, when he was free, could have his rights and protect themselves. He said, The colored people could never protect themselves among the white people. So you had all better stay with the white people who raised you and make contracts with them to work by the year for one-fifth of all you make. And next year you can get one-third, and the next you maybe work for one-half you make. We have contracts for you all to sign, to work for one-twentieth you make from now until the crop is ended, and then next year you all can make another crop and get more of it.I told him I would not sign anything. I said, I might sign to be killed. I believe the white people is trying to fool us. But he said again, Sign this contract so I can take it to the Yankees and have it recorded. All our colored people signed it but myself and a boy named Samuel Jefferson. All who lived on the place was about sixty, young and old. On the day after all had signed the contracts, we went to cutting oats. I asked the boss, Could we get any of the oats? He said, No; the oats were made before you were free. After that he told us to get timber to build a sugar-mill to make molasses. We did so. On the 13th day of July 1865 we started to pull fodder. I asked the boss would he make a bargain to give us half of all the fodder we would pull. He said we may pull two or three stacks and then we could have all the other. I told him we wanted half, so if we only pulled two or three stacks we would get half of that. He said, All right. We got that and part of the corn we made. We made five bales of cotton but we did not get a pound of that. We made two or three hundred gallons of molasses and only got what we could eat. We made about eight-hundred bushel of potatoes; we got a few to eat. We split rails three or four weeks and got not a cent for that.1.
