Divide the actual distance of the scale by the map distance of the scale, which is 15/0.25 = 60. This shows that the scale is 1 cm:60 miles.
If the distance between two cities on a map is 6.8 cm, multiply by 60 to get the real distance between the two cities in miles, which is 408 miles.
408 miles

When the slope of a line is undefined, it means that the line is either vertical or horizontal. If the x intercept is -7, the equation would be
x = -7
There is no solution.
To solve it using the substitution method, substitute y from the y = 3x - 4 equation into the 9x - 3y = 14 equation, like so:
9x - 3(3x - 4) = 14
Then after foiling:
9x - 9x -12 = 14
Since there are two x's on the same side, we can just cancel them out leaving:
-12 = 14
Since -12 most definitely does not equal 14, the equation has no solution.
I used this website as a reference: http://www.purplemath.com/modules/systlin4.htm. If it doesn't make sense then you can find some other examples on there that may help you. I hope this helps.
Answer:
<u>Step-by-step explanation:</u>
This is a special triangle because the side lengths have the following relationship:
30° ⇄ side length "a" <em>represented as "h" in your picture</em>
60° ⇄ side length "a√3" <em>represented as "g" in your picture</em>
90° ⇄ side length "2a" <em>represented as "√5" in your picture</em>
<u>Step 1: solve for "a" </u> <em>hypotenuse (2a) is given as √5</em>
According to your picture, a = h, so
<u>Step 2: use the a-value from Step 1 to solve for the remaining side</u>
