Answer:

tan(15°) = 73/x

Step-by-step explanation:

tan(15°) = 73/x

Because tangent is opposite (73 foot height) over adjacent (the x feet distance from the foot of the bridge to the boat on the water).

5) The school that Lexy goes to is selling tickets to the annual talent show. On the first day

Juli2301 [7.4K]

Answer:

Adult ticket is $6

Student ticket is $4, as you said.

Step-by-step explanation:

We'll call adult tickets x and student tix y.

14x + 11y = 128

14x + y = 88

First, solve the second equation for y in terms of x:

y = 88- 14x

Then substitute that for y into the first equation:

14x + 11(88-14x) = 128

14x + 968 - 154x = 128

-140x = -840

x = 6 The adult ticket is $6, like you said.

Now take that and solve for y:

y = 88 - 14(6)

y = 88 - 84

y = 4 The student ticket is $4, as you said.

Hope this helps. Feel free to ask questions so you can understand.

Find the slope of the line joining the points (-1,5) and (6,-2). Also find the equation of that straight line. Find the intercep

Nesterboy [21]

The slope of the line joining the points (-1,5) and (6,-2) is -1

x + y = 4 is the equation of line

x intercept is (-4, 0)

y intercept is (0, 4)

Solution:

Given that,

Points are (-1,5) and (6,-2)

The slope of line is given as:

$m = \frac{y_2-y_1}{x_2-x_1}$

From given,

$(x_1, y_1) = (-1, 5)\\\\(x_2, y_2) = (6, -2)$

Substituting the values we get,

$m = \frac{-2-5}{6+1}\\\\m = \frac{-7}{7}\\\\m = -1$

Thus slope of line is -1

The equation of line in slope intercept form is given as:

y = mx + c -------- eqn 1

Where,

m is the slope

c is the y intercept

Substitute m = -1 and (x, y) = (-1, 5) in eqn 1

5 = -1(-1) + c

5 = 1 + c

c = 4

Substitute m = -1 and c = 4 in eqn 1

y = -x + 4

In standard form,

x + y = 4 is the equation of line

Find x intercept:

Substitute y = 0

x + 0 = 4

x = -4

Thus x intercept is (-4, 0)

Find y intercept:

Substitute x = 0

0 + y = 4

y = 4

Thus y intercept is (0, 4)
