For the equation y=7x+3 the value of X changes from 1 to 2

2 answers:

When x=1, 7x+3 = 10. When x=2, 7x+3 = 17. When the value of 'x' changes from '1' to '2', the value of 7x+3 changes from '10' to '17' . . . a distance of '7' . That's what the ' 7x ' in the equation means, and that's what we mean when we say that the 'slope' of the equation is '7'. 'y' changes '7' for every '1' that 'x' changes. Hope this helps :))

When x=1, 7x+3 = 10.

When x=2, 7x+3 = 17.

When the value of 'x' changes from '1' to '2', the value of 7x+3 changes
from '10' to '17' . . . a distance of '7' .

That's what the ' 7x ' in the equation means, and that's what we mean
when we say that the 'slope' of the equation is '7'. 'y' changes '7' for
every '1' that 'x' changes.

Find the zeros of the function.

Zigmanuir [339]

Answer:

x = 3, x = 4

Step-by-step explanation:

To find the zeros of the function, equate f(x) to zero, that is

(x - 3)(2x - 8) = 0

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3 ← smaller solution

2x - 8 = 0 ⇒ 2x = 8 ⇒ x = 4 ← larger solution

You are sitting at the edge of the Grand Canyon admiring the view when you notice a tour group at the bottom of the canyon. You

ololo11 [35]

Answer:

7949.13 feet

Step-by-step explanation:

We are given that,

Angle of depression from the spot to the group = 39°

Height of Grand Canyon = 5000 feet.

So, we will get the following figure of a right triangle.

<em>As, 'in a right triangle, the angles and the sides can be written in trigonometric form'.</em>

We get, $\sin A=\frac{perpendicular}{hypotenuse}$

i.e. $\sin 39=\frac{5000}{x}$

i.e. $x=\frac{5000}{\sin 39}$

i.e. $x=\frac{5000}{0.629}$

i.e. x = 7949.13 feet

Thus, the line of sight distance is 7949.13 feet.

Juli2301 [7.4K]

There are 16 ounces in one pound. So we do 7 divided by 16 to get our answer.

7 / 16 = 0.4375 ≈ 0.4 lbs
