two bags and four hats cost $100 in all. three bags and seven hats cost $164 in all. what is the cost of 1 hat?
Natali [406]

Answer:

Bags = 22

Hat = 14

22 x 2 = 44

14 x 4 = 56

So the first part is true

3 x 22 = 66

7 x 14 = 98

So the second part is true

14 is the answer

It's trial and error

The graph of f passes through (-6,9) and is perpendicular to the line that has an x-intercept of 8 and a y-intercept of -24 the
Valentin [98]

Given:

The graph of f passes through (-6,9).

It is perpendicular to the line that has an x-intercept of 8 and a y-intercept of -24.

To find:

The equation of the function f.

Solution:

The equation of line on which graph of f is perpendicular, is

\dfrac{x}{a}+\dfrac{y}{b}=1

where, a and b are x and y intercepts respectively.

\dfrac{x}{8}+\dfrac{y}{-24}=1

Multiply both sides by 24.

3x-y=24

Slope intercept form is

y=3x-24

Slope of this line is 3 and y-intercept is -24.

Product of slopes of two perpendicular lines is -1.

Let the slope of f is m. So,

m\times 3=-1

m=-\dfrac{1}{3}

Slope of m is -1/3 and it passes through (-6,9). So, the equation of function f is

y-y_1=m(x-x_1)

y-9=-\dfrac{1}{3}(x-(-6))

y-9=-\dfrac{1}{3}(x+6)

y-9=-\dfrac{1}{3}x-2

y=-\dfrac{1}{3}x-2+9

y=-\dfrac{1}{3}x+7

Put y=f(x).

f(x)=-\dfrac{1}{3}x+7

Therefore, the required function is f(x)=-\dfrac{1}{3}x+7.
