Answer:

Slope = 8.000/2.000 = 4.000

x-intercept = 10/4 = 5/2 = 2.50000

y-intercept = -10/1 = -10.00000

Step-by-step explanation:

y= mx + b is the slope intercept form of a line where m is the slope and b is the y intercept.

Step 1 : Equation of a Straight Line

Step 2: Graph of a Straight Line

Step 3: Calculate the Y-Intercept

Step 4: Calculate the X-Intercept

Step 5: Calculate the Slope

Hope this helps.

-8x-27=-7\left(1+2x\right)+2x

Darina [25.2K]

Answer:

$x=5$

Step-by-step explanation:

$-8x-27=-7\left(1+2x\right)+2x$

Expand:

$-8x-27=-7\times 1-7\times 2x+2x$

$-8x-27=-7-12x$

Add 27 to both sides:

$-8x-27+27=-7-12x+27$

$-8x=-12x+20$

Add 12x to both sides:

$-8x+12x=-12x+20+12x$

$4x=20$

Divide both sides by 4:

$\frac{4x}{4}=\frac{20}{4}$

$x=5$

3/4 x 3 2/5 - 5/5(find the value of each of the following)

Triss [41]

The value of the given expression is $\frac{-13}{20}.$

Solution:

Given expression is $\frac{3}{4} \times3\frac{2}{5}-\frac{5}{5}$ .

Let us first convert mixed fraction into improper fraction.

$3\frac{2}{5}=\frac{(3\times5)+2}{5}=\frac{17}{5}$

Substitute this in the given expression.

$\frac{3}{4} \times3\frac{2}{5}-\frac{5}{5}=\frac{3}{4} \times\frac{7}{15}-\frac{5}{5}$

$=\frac{21}{60}-\frac{5}{5}$

To simplify the above expression, 21 and 60 are cancelled by 3.

$=\frac{7}{20}-\frac{1}{1}$

Do cross multiplication to make the denominator same.

$=\frac{7}{20}-\frac{20}{20}$

$=\frac{7-20}{20}$

$=\frac{-13}{20}$

The value of the given expression is $\frac{-13}{20}.$

The length of a rectangle is 5 less than twice the width. If the perimeter of the rectangle is 146 cm, find the dimensions of th

Marta_Voda [28]

Length = 2x - 5

Width = x

Perimeter = 146

P = 2L + 2W

146 = 2(2x - 5) + 2x

146 = 4x - 10 + 2x

146 = 6x - 10

146 + 10 = 6x

156 = 6x

156/6 = x

26 = x

Length = 2(26) - 5

Length = 52 - 5

Length = 47 cm

Width = x

Width = 26 cm

7 groups of 8=6 groups of 8 plus

vredina [299]

Answer:

7 groups of 8 = 6 groups of 8 plus 1 group of 8

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

7 groups of 8 = 6 groups of 8 plus ?

2. Let's answer the question, this way:

How much are 7 groups of 8? 56 = 7 * 8

How much are 6 groups of 8? 48 = 6 * 8

What is the difference between 7 groups of 8 and 6 groups of 8?

(7 - 6 ) * 8 = 1 * 8

Therefore,

7 groups of 8 = 6 groups of 8 plus 1 group of 8
