Find the point of intersection of the lines 3=6x-y and 3x-2y=24 ?

Svet_ta [14]

$\left \{ {{3=6x-y\ \ |*(-2)} \atop {3x-2y=24}} \right. \\\\ \left \{ {{-6=-12x+2y} \atop {24=3x-2y}} \right. \\+----\\add\ both\ equations\\\\
18=-9x\ \ \ | divide\ by\ -9\\\\
x=-2\\\
y=6x-3=6*(-2)-3=-12-3=-15\\\\
Point\ of\ intersection:\ (-2,-15)$

Plot the x- and y-intercepts to graph the equation y=-x-5

Rainbow [258]

The y intercept is the y value determined when x = 0
y = -0 - 5
y = - 5
The y intercept is (0,-5)

The x intercept is where y = 0
0 = -x - 5
5= -x
x = - 5
The x intercept is (- 5, 0)

Artaud is 12. To get this answer you first have to work backwards. So subtract 40 from 28 and you get -12. Then find the opposite of that which is 12.

The Martinez family walked three over five of a mile in three over eight of an hour. What is their unit rate in miles per hour?

Vikki [24]

Answer:

three-fifths over three-eights equals one and three-fifths miles per hour

Step-by-step explanation:

The martinez family walked three over five of a mile; this means they walked 3/5 of a mile.
They walked such distance in in three over eight of an hour, this means 3/8 of an hour.

To find the rate in miles per hour, we have to divide 3/5 divided 3/8.

$\frac{3}{5} /\frac{3}{8}$

TO make division of fraction, we must invert the second fraction and multiply them:

$\frac{3}{5} *\frac{8}{3} =\frac{8}{5}$

The ratio is 8/5 miles per hour. In the answer given it is expressed as a mixed numer 1 3/5 that is equal to 8/5.

To transform a fraction to a mixed number, you have to divide numerator by denominator. Explanation is in figure attached.
