The number of cups of sugar in the recipe is 2/3 (0.67) times the number of cups of oats (because for every 2 cups of sugar, there are 3 cups of oats).

The number of cups of oats in the recipe is 3/2 (1.5) times the number of cups of sugar (because for every 3 cups of oats, there are 2 cups of sugar).

angle a and b are complementary. m angle a = 2x and m angle b = 4x +30. what is the measure of the angle supplementary to angle

Papessa [141]

M>a + m>b = 90 (complementary angle)
2x + 4x +30 = 90
6x + 30 = 90
6x + 30 -30 = 90-30
6x = 60
6x/6 = 60
x=10
The m>a = 2x
m>a = 20
Supplemenary angles must add up to 180. So, 180- 20 = 160
So the measure of the angle supplementary to angle a is 160°

What is the equation of the line that is perpendicular to the like y=-4x + 7 and passes through the point (8,2)?

Nookie1986 [14]

Answer:

$y=\frac{1}{4}x$

Step-by-step explanation:

Given equation of line:

$y=-4x+7$

To find the equation of line perpendicular to the line of the given equation and passes through point (8,2).

Applying slope relationship between perpendicular lines.

$m_1=-\frac{1}{m_2}$

where $m_1$ and $m_2$ are slopes of perpendicular lines.

For the given equation in the form $y=mx+b$ the slope $m_2$ can be found by comparing $y=-4x+3$ with standard form.

∴ $m_2=-4$

Thus slope of line perpendicular to this line $m_1$ would be given as:

$m_1=-\frac{1}{-4}$

∴ $m_1=\frac{1}{4}$

The line passes through point (8,2)

Using point slope form:

$y_-y_1=m(x_-x_1)$

Where $(x_1,y_1)\rightarrow (8,2)$ and $m=m_1=\frac{1}{4}$

So,

$y-2=\frac{1}{4}(x-8)$

Using distribution.

$y-2=(\frac{1}{4}x)-(\frac{1}{4}\times 8)$

$y-2=\frac{1}{4}x-2$

Adding 2 to both sides.

$y-2+2=\frac{1}{4}x-2+2$

$y=\frac{1}{4}x$

Thus the equation of line in standard form is given by:

$y=\frac{1}{4}x$
