If you solve by substitution , you would get and the equation -3x-2(5x-7)=12 which if you solve becomes a -3x-10x+14=12
You than want to combine like terms , so you combine -3x and -10x and bring the other problem down.
-13x+14=12
You subtract the 14 from itself and the 12 to leave -13 with its variable alone.
Now you should have -13x=-2
You divide both sides by -13 and you’ll get x=2/13
Next step is you plug back this answer to the y=5x-7
And you’ll get y= -81/13

Next time, write down the problem.

y = 5x - 7 -3x - 2y = -12

Creative box:

(5x - 7) - (3x - 2y) = -12

5x - 3x = 2x

(2x - 7) - (2y)

y = -12

2 x -12 = -24

(2x - 7)  (-24) = answer (i'm not sure if its right, because I don't know if that is how the answer was supposed to be written)

Serjik [45]

Answer:

The scale used on his map is <u>150 miles : 2 inches</u>.

Step-by-step explanation:

Given:

Ted knows the actual distance between two cities is 150 miles. His map shows a distance of 2 inches between these cities.

Now, to find the scale Ted used on his map.

The actual distance Ted know between two cities = 150 miles.

The distance on map between these cities = 2 inches.

So, to get the scale used on his map:

\frac{The\ actual\ distance\ Ted\ know\ between\ two\ cities}{The\ distance\ on\ map\ between\ these\ cities}

=\frac{150\ miles}{2\ inches}

=150\ miles:2\ inches.

Therefore, the scale used on his map is 150 miles : 2 inches.

stepan [7]

Answer: Mean=4.11

Median=4.44

Step-by-step explanation:

Using a graphing calculator, enter the values into the first list.  Then run one-variable statistics on the list.

By hand, to find the mean, add together all of the values:

3.25+3.25+3.66+3.83+4.57+4.52+4.74+4.69+4.44 = 36.95

Divide by the total number of data points, 9:

36.95/9 = 4.11

To find the median, order the data from least to greatest:

3.25, 3.25, 3.66, 3.83, 4.44, 4.52, 4.57, 4.69, 4.74

The middle number is 4.44

Which is the correct form of q(x) + r(x)/b(x) for expression 7x^4+x+14/x+2
BARSIC [14]
<span>(7x^4+x+14)/(x+2)
</span>(7x^4+x+14)----------------------|(x+2)
-14x³+x+14-------------------------7x³-14x²+28x-55------> q(x)
28x²+x+14
-55x+14
110+14=124------------------------> r(x)
<span>
 </span>r(x)=124
b(x)=x+2
q(x)=7x³-14x²+28x-55

then
q(x) + r(x)/b(x)---------> (7x³-14x²+28x-55)+(124)/(x+2)

the answer is (7x³-14x²+28x-55)+(124)/(x+2)
