Answer: The y-intercept (b) is 10.

Step-by-step explanation:

Use the slope and the point to help you. Plot the point (-3,4) on graphing paper or use geometry software. I use geometry software, it's easier.

You'll need to understand that the slope 2 can also be written as 2/1 (rise/run). Go up 2 units and go to the right 1 unit, then plot a point. Keep going until one of the points lies on the y-axis. The y-coordinate of that point is the y-intercept. So, the y-intercept (aka "b") is 10.

You're welcome, and I have a nice day! :D

The sum of a number times 10 and 17 is at most 27
guajiro [1.7K]

<em>Answer:</em>

<em>The value of the number should be 1 (or less I think)</em>

<em>Step-by-step explanation:</em>

<em>At most means the highest value of the sum should be 27.</em>

<em>10x + 17 = 27</em>

<em>10x = 27 - 17</em>

<em>10x = 10</em>

<em>x = 10/10</em>

<em>x = 1</em>

<em>∴</em><em>The value of the number should be 1</em>

A wire is stretched from the ground to the top of an antenna tower. The wire is 15 feet long. The height of the tower is 3 feet
Mariana [72]

The distance d is 9 ft and the height is 12ft.

<h3>How to find the distance and the height?</h3>

Here we can model the situation with a right triangle, where the length of the wire is the hypotenuse.

The height is one cathetus and the distance is the other catheti.

Let's define:

  • h = height
  • d = distance.
  • hypotenuse = 15ft

We know that the height of the tower is 3 ft larger than the distance, then:

h = d + 3ft

Now we can use the Pythagorean theorem, it says that the sum of the squares of the cathetus is equal to the square of the hypotenuse.

Then:

d^2 + (d + 3ft)^2 = (15ft)^2

Now we can solve this equation for d:

d^2 + d^2 + 6ft*d + 9ft^2 = (15ft)^2\\\\2d^2 + 6ft*d - 216 ft^2 = 0\\\\d^2 + 3ft*d - 108ft^2 = 0

Then the solutions are:

d = \frac{-3ft \pm \sqrt{(3ft)^2 - 4*(-108ft^2)} }{2} \\\\d = \frac{-3ft \pm 21ft }{2}

We only take the positive solution:

d = (-3ft + 21ft)/2 = 9ft

And the height is 3 ft more than that, so:

h = 9ft + 3ft = 12ft

The distance d is 9 ft and the height is 12ft.

8<br> Which expression is equivalent to 4.8 + 2.2w – 1.4w + 2.4?
krok68 [10]

Answer:

7.2 + 0.8w

Step-by-step explanation:

Combine like terms.

Here Like terms: i) 2.2w and (-1.4w)

                         II)   4.8 and 2.4

4.8 + 2.2w - 1.4w + 2.4 = 4.8 + 2.4 + 2.2w - 1.4w

                                     = 7.2 + 0.8w
