2 answers:

5 0

So you have to start by distributing the -2 and the 4 so the equation would look like this
-2x+6-8x+32
Next you would add the like values so
10x+38
So the answer would be

10x+38

Suppose 52% of students chose to study French their junior year, and that meant that there were 312 such students. How many stud

Charra [1.4K]

Answer:

288

Step-by-step explanation:

If 52% studied French, then 48% didn't. The ratio of those who didn't to those who did is ...

(didn't study French)/312 = 48%/52% = 12/13

Then the number that didn't study French is ...

(didn't study French) = 312 × 12/13 = 288 . . . . . . multiply above by 312

288 students chose not to take French their Junior year.

Circle A has radius 5, and Circle B has radius 2. If CD = 12 and is a common

Dahasolnce [82]

Answer:

$3\sqrt{17}$ or \approx 12.37$ Units$

Step-by-step explanation:

In the attached diagram

CA=CO+OA

CO=DB

Therefore:

5=2+OA

OA=3 Units

The angle between a tangent line and a radius is 90 degrees. therefore triangle OAB is a right triangle with:

OB=12 units

OA=3 units

Using Pythagoras theorem

$AB=\sqrt{3^2+12^2}\\ =\sqrt{153}\\=3\sqrt{17}$ or \approx 12.37$ Units$

What is the solution to the system of linear equations graphed below?

OlgaM077 [116]

Option C: There are no solutions

Explanation:

The linear equations is graphed.

We need to determine the solution of the system of equations.

The solution of the equations can be determined by finding the point of intersection of the two equations.

From the figure, it is obvious that the two equations are parallel to each other.

Also, the parallel lines have the same slope and the parallel lines never intersect.

Hence, the system consisting of parallel lines have no solution.

Therefore, the solution to the system of linear equations graphed is no solution.

Thus, Option C is the correct answer.
