For the equation y=7x+3 the value of X changes from 1 to 2

Mathematics

When x=1, 7x+3 = 10. When x=2, 7x+3 = 17. When the value of 'x' changes from '1' to '2', the value of 7x+3 changes from '10' to '17' . . . a distance of '7' . That's what the ' 7x ' in the equation means, and that's what we mean when we say that the 'slope' of the equation is '7'. 'y' changes '7' for every '1' that 'x' changes. Hope this helps :))

When x=1, 7x+3 = 10.

When x=2, 7x+3 = 17.

When the value of 'x' changes from '1' to '2', the value of 7x+3 changes
from '10' to '17' . . . a distance of '7' .

That's what the ' 7x ' in the equation means, and that's what we mean
when we say that the 'slope' of the equation is '7'.  'y' changes '7' for
every '1' that 'x' changes.

If a digit is 4 or smaller, it rounds down.
If a digit is 5 or more, it rounds up.
The number is 2, 746, 052 so it stays at 700,000.

TLDR: 2,700,000

the length of a new rectangle playing field is 6 yards longer than quadruple the width. if the perimeter of the rectangle plaing
Vika [28.1K]

The length and width of a new rectangle playing field are 214 yards and 52 yards respectively.

<h3>What is the area of the rectangle?</h3>

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

We have:

The length of a new rectangle playing field is 6 yards longer than quadruple the width.

Let's suppose the length is l and width is w of a rectangle:

From the problem:

l = 6 + 4w

Perimeter P = 2(l + w)

532 = 2(l + w)

Plug l = 6+4w in the above equation:

532 = 2(6 + 4w + w)

266 = 6 + 5w

260 = 5w

w = 52 yards

l = 6 +4(52) = 214 yards

Thus, the length and width of a new rectangle playing field are 214 yards and 52 yards respectively.

Laila and Bryson are finding the slope of a line that passes through the two points (3, -5) and (-4, -6). Who is correct and why
snow_tiger [21]
Slope formular = (y2-y1)/(x2 - x1)
so
slope = (-6 +5)/(-4-3) 
slope = -1/-7
slope = 1/7

You are making a welding fixture and must cut down a length of copper tubbing from 15 1/8 inches to 8 3/4 inches. If the leftove
Bumek [7]

Answer:   6\dfrac{3}{8}\text{ inches}

Step-by-step explanation:

Given: Original length = 15\dfrac{1}{8} inches

=\dfrac{8\times15+1}{8}=\dfrac{121}{8} inches                      ( In improper fraction )

Length of piece cut from original = 8\dfrac{3}{4} inches

=\dfrac{4\times8+3}{4}= \dfrac{35}{4} inches                 ( In improper fraction )

Length of piece leftover piece =  (Original length ) - (Length of piece cut )

=\dfrac{121}{8}-\dfrac{35}{4}\\\\=\dfrac{121-2\times35}{8}\\\\=\dfrac{121-70}{8}\\\\=\dfrac{51}{8}\\\\=6\dfrac{3}{8}\text{ inches}

Hence, the leftover piece will be 6\dfrac{3}{8}\text{ inches}  long.

Use a negative factor to factor the expression - 7a+49b - 35
Helen [10]

Answer:

using a negative facto to factor the expression will be:

- 7a+49b - 35 = -7(a-7b+5)

Step-by-step explanation:

Given the expression

- 7a+49b - 35

Rewrite -35 as 5 · 7

Rewrite 49 as 7 · 7

so

= -7a + 7 · 7b - 5 · 7

as -7 is the common factor, so factoring out

= -7(a-7b+5)

Thus, using a negative facto to factor the expression will be:

- 7a+49b - 35 = -7(a-7b+5)
