I need help pls!! 20 points I need it!!

dolphi86 [110]

Answer: About 6.71 units

Step-by-step explanation:

You use the distance formula: $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }$ .

Assign the the two points to the variables:

$(x_{1}, y_{1}) = (1, 3)\\(x_{2}, y_{2}) = (4, -3)$

Substitute them in the formula:

$\sqrt{(4-1)^{2}+(-3-3)^{2}}$

And solve it:

$\sqrt{(4-1)^{2}+(-3-3)^{2}}\\=\sqrt{(3)^{2}+(-6)^{2}}\\=\sqrt{9+36}\\=\sqrt{45}\\=6.71$

Chantal is driving on a highway at a steady speed. She drives 55 miles every hour. Let d be the total distance in miles and let

strojnjashka [21]

Answer:

$d = 55h$

Step-by-step explanation:

We are given that Chantal drives at a constant speed of 55 miles per hour.

If, d represents the total distance in miles, and

h represents number of hours, the following equation can be used to express the given situation:

$d = 55h$

For every hour, a distance of 55 miles is covered.

Thus, if h = 1, $d = 55(1) = 55 miles$

If h = 2, $d = 55(2) = 110 miles$ .

Therefore, $d = 55h$ , is an ideal equation that represents the situation given in the question above.
