Anettt [7]2 years ago

3 0

Answer:

Step-by-step explanation:

we want y = mx + b

4x = 2y - 3

-2y = -4x - 3

2y = 4x - 3

therefore the gradient (slope) = the coeffecient of x, which in this case is 4

Find the parallel and perpendicular slope of a line if linear equation is 7y=20(x-3) Slope (Parallel) is ____ Slope (Perpendicul

yKpoI14uk [10]

Answer:

The parallel line has slope $\frac{20}{7}$

The perpendicular line has slope $-\frac{7}{20}$

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope.

Parallel lines:

Parallel lines have the same slope.

Perpendicular lines:

If two lines are perpendicular, the multiplication of their slopes is -1.

In this question:

We have the following line:

$7y = 20(x-3)$

Placing it in the general format

$7y = 20x - 60$

$y = \frac{20x}{7} - \frac{60}{7}$

So this line has slope $\frac{20}{7}$

Parallel line:

Same slope, so the parallel line has slope $\frac{20}{7}$

Perpendicular line:

Multiplication of the slopes is -1. So

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

$20m = -7$

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

The perpendicular line has slope $-\frac{7}{20}$

How do you solve equations like this

dimaraw [331]

the multiplication of fractions is very straightforward, numerators across and denominators across, now, let's firstly convert the mixed fraction to improper fraction.

$\bf \stackrel{mixed}{2\frac{2}{5}}\implies \cfrac{2\cdot 5+2}{5}\implies \stackrel{improper}{\cfrac{12}{5}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{12}{5}\cdot \cfrac{5}{7}\implies \cfrac{12}{7}\cdot \cfrac{5}{5}\implies \cfrac{12}{7}\cdot 1\implies \cfrac{12}{7}\implies 1\frac{5}{7}$

HELP DUE IN 20 MINS!!!!!!

Amiraneli [1.4K]

Answer:

10 miles

Step-by-step explanation:

Set up a proportion: $\frac{15}{1.5} = \frac{x}{1}$
Cross multiply, then divide: 15 × 1 = 15, 15 ÷ 1.5 = 10
So, Jessica can run 10 miles in 1 hour

I hope this helps!
