Find the slope of the lines. Are the 2 lines parallel or perpendicular? Explain how you can use the slope of two lines to tell i

rewona [7]

Answer:

slope = $\frac{3}{7}$ and - $\frac{7}{3}$ , perpendicular

Step-by-step explanation:

the equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = $\frac{3}{7}$ x + 11 is in this form with m = $\frac{3}{7}$

Rearrange 7x + 3y = 13 into this form

subtract 7x from both sides

3y = - 7x + 13 ( divide all terms by 3 )

y = - $\frac{7}{3}$ x + $\frac{13}{3}$ ← in slope- intercept form

with m = - $\frac{7}{3}$

• Parallel lines have equal slopes

• The product of perpendicular slopes = - 1

The lines are not parallel since slopes are not equal

$\frac{3}{7}$ × - $\frac{7}{3}$ = - 1

Hence lines are perpendicular

how many ways are there to adjust two quantities so that they are in a given proportional relationship? Explain your reasoning.

dolphi86 [110]

The question is, "how many ways ...".

There are as many ways to solve a math problem as you can think of. (Some are shorter or easier than others.)

Essentially, an infinite number.

A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.

Dan pays £714.73 a year in his car insurance. The insurance company reduces the price by 4.1%. How much does the insurance cost

FrozenT [24]

Answer:

£682.57

Step-by-step explanation:

Dan pays £714.73 a year in his car insurance.

The price was reduced by 4.1%

To find the new cost of the insurance, we simply need to find 4.15% of £714.73 and then subtract that from the initial price of the insurance (£714.73)

4.5% of 714.73 is:

$\frac{4.5}{100} * 714.73$ = £32.16

Then, the cost of the insurance now is:

£714.73 - £32.16 = £682.57

The insurance now costs £682.57
