Solve the system by substitution.

-5x+2y=-42

6x=y

Answers

Answer 1

Step-by-step explanation:

since y=6x

by substitution

-5x+ 2 (6x)= -42

-5x+ 12x=-42

7x= - 42

divide both sides by 7

x= 6

y=6x

y =6*6

y=36

A system of equations is shown.

y = 2x – 7

y = -x + 5

What is the solution to the system of equations?

Answers

Answer:

x = 4

Step-by-step explanation:

Eliminate y by setting the first equation equal to the second:

2x - 7 = -x + 5

Combining like terms, we get:

3x = 12, so that x must be 4.

Becky and Keith run for exactly 20 minutes on a treadmill keith's treadmill said he had run 10,000 ft Becky's treadmill had said she had run 2 miles who ran farther and how much farther?​

Answers

Answer:

Becky ran farther and farther by 560 ft.

Step-by-step explanation:

1 mile = 5280 ft

Becky: 2 * 5280 = 10560 ft

Keith: 10000 ft

10560 ft > 10000 ft, so Becky ran more distance than Keith.

10560 - 10000 = 560 ft, so Becky ran 560 ft more than Keith.

Steps:

ALI = 48×12/2 = 48×6 = 288 in²

AIEN = 48×32 = 1536 in²

ALIEN = ALI + AIEN

Find the distance from the point P(4,1) to the line segment joining the points Q(1,-8) and R(-4,2). Show your steps.

Answers

Answer:

7,8

Step-by-step explanation:

Distance Formula:

The distance between two points is the length of the path connecting them. The shortest path distance is a straight line. In a 2 dimensional plane, the distance between points (X1, Y1) and (X2, Y2) is given by the Pythagorean theorem:

d=(x2−x1)2+(y2−y1)2−−−−−−−−−−−−−−−−−−√

Calculate Distance

To calculate the distance between 2 points, (X1, Y1) and (X2, Y2), for example, (5, 6) and (-7,11), we plug our values into the distance formula:

d=(−7−5)2+(11−6)2−−−−−−−−−−−−−−−−−√

combining terms inside parentheses we get:

d=(−12)2+(5)2−−−−−−−−−−−√

squaring both terms we get,

d=144+25−−−−−−−√

adding the 2 results,

d=169−−−√

finally,

d=13

[tex]15 = \sqrt{121 + 2y + y^2 + 4}[/tex]

[tex](15)^{2} =( \sqrt{121 + 2y + y^2 + 4})^{2}[/tex]

Answers

Answer:

See Explanation

Step-by-step explanation:

Let us assume that [tex] 5\sqrt 7[/tex] is a rational.

Therefore, it can be expressed in the form of [tex] \frac{p}{q}[/tex], where p and q are integers.

[tex] \implies 5\sqrt 7=\frac{p}{q}[/tex]

[tex] \implies \sqrt 7=\frac{p}{5q}[/tex]

[tex] \because [/tex] p and q are integers.

[tex] \therefore \frac{p}{5q}[/tex] is a rational number.

[tex] \implies \sqrt 7[/tex] is rational ([tex] \because [/tex] quotient of a rational number is rational)

But, it contradicts the fact that [tex]\sqrt 7[/tex]is irrational.

So, [tex]5\sqrt 7[/tex] is also irrational, because the product of rational and irrational is irrational.

This contradiction is arising out because of our wrong assumption that [tex] 5\sqrt 7[/tex] is rational.

Hence, [tex] 5\sqrt 7[/tex] is irrational.
