Answer:

1. 0.82x

2. 1.18x

3. (7/10)x

4. (3/10)x

Step-by-step explanation:

When something is discount off 18 percent, it lowers the orginal price by 18 percent. Pretend the original price is x. Taking out 18 percent would be 0.82x

Same thing. 18 percent more, would be 1.18x since instead of subtracting, you add. 1.18x

3/10 in percent form is 30 percent. 100 - 30 = 0.7 so 0.7x

Since it has 3/10 <em>of </em> the orginal, it is multiply. If the orginal is x, x * 3/10 = (3/10)x.

Write and equati9n of a l8ne that passes through (1,-2) and is perpendicular to -4x+7y=21

yarga [219]

Given:

A line passes through (1,-2) and is perpendicular to $-4x+7y=21$ .

To find:

The equation of that line.

Solution:

We have, equation of perpendicular line.

$-4x+7y=21$

Slope of this line is

$m_1=-\dfrac{\text{Coefficient of x}}{\text{Coefficient of y}}$

$m_1=-\dfrac{-4}{7}$

$m_1=\dfrac{4}{7}$

Product of slope of two perpendicular lines is -1.

$m_1\times m_2=-1$

$\dfrac{4}{7}\times m_2=-1$

$m_2=-\dfrac{7}{4}$

Now, slope of required line is $-\dfrac{7}{4}$ and it passes through (1,-2). So, the equation of line is

$y-y_1=m(x-x_1)$

where, m is slope.

$y-(-2)=-\dfrac{7}{4}(x-1)$

$4(y+2)=-7(x-1)$

$4y+8=-7x+7$

$4y+7x=7-8$

$7x+4y=-1$

Therefore, the equation of required line is $7x+4y=-1$ .
