Answer:
x=6, y=3. (6, 3).
Step-by-step explanation:
3x-2y=12
3x+5y=33
--------------
-3x+2y=-12
3x+5y=33
-------------------
7y=21
y=21/7=3
3x-2(3)=12
3x-6=12
3x=12+6
3x=18
x=18/3=6

Does the point (–1, 5) satisfy the equation y = 7x?
Answer:
no
Step-by-step explanation:
Substitute the x- coordinate into the equation and if the result is equal to the y- coordinate then it satisfies the equation, that is
y = 7(- 1) = - 7 ≠ 5
Then (- 1, 5 ) is not a solution to the equation

Terms/CoefficientsStep-by-step explanation:
Step 1: Define
-41 = -2/5(45n + 60) + n
Step 2: Solve for n
Distribute -2/5: -41 = -18n - 24 + nCombine like terms: -41 = -17n - 24[Addition Property of Equality] Add 24 on both sides: -17 = -17n[Division Property of Equality] Divide -17 on both sides: 1 = nRewrite/Rearrange: n = 1Step 3: Check
Plug in n into the original equation to verify it's a solution.
Substitute in n: -41 = -2/5(45(1) + 60) + 1(Parenthesis) Multiply: -41 = -2/5(45 + 60) + 1(Parenthesis) Add: -41 = -2/5(105) + 1Multiply: -41 = -42 + 1Add: -41 = -41Here we see that -41 does indeed equal -41.
∴ n = 1 is the solution to the equation.

Eleonore wants to prove that if a line divides two sides in a triangle proportionally, then it is parallel to the third side.
Please find image attached
Answer and explanation:
If (from the image attached) DE is a line segment that divides the sides AB and AC proportionally in ΔABC then we can prove that line segment DE is parallel to BC using the parallel transversal theorem. Based the parallel transversal theorem, the triangles ABC and ADE are similar therefore angles are congruent and line DE must be parallel to line BC

An account earns simple interest. Find the principal.
Interest earned: $27
Principal: ?
Interest rate: 1.5%
Time: 2 years
The principal is $
Answer:
$ 900
Step-by-step explanation:
Simple interest = Principle * Time * Rate / 100
Now by substituting :
27 = Principle * 2 * 1.5 / 100
Principle = 27 * 100 / 2 * 1.5
Principle = 2700 / 3
So Principle = $ 900

The measure of the angle from the given figure is 85°.
In the given figure, the measure of angle is given.
What is an angle?An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.
In the given figure, the ray is between 90° and 80°
So, the measure of the angle is 85°

Answer:
∠P = 110º
∠Q = 70º
Step-by-step explanation:
we know that a straight line is equal to 180º and since we already have one angle (70º) all we have to do is subtract 70 from 180.
180 - 70 = 110º
we also know that vertical angles are congruent (the same) so we're already given angle q.
