There are infinitely many solutions to a linear equation with the same variable term on both sides of the equation.
We have to find the coefficient of "b"
from first equation:
2a + b = -6b = -6 - 2afrom second equation:
6a + kb = -18b = (-18 - 6a)/ksolve them simultaneously:
(-18 - 6a)/k = -6 - 2a(-18 - 6a)/(-6 - 2a) = kk = 3Gina's bedroom floor is in the shape of a rectangle. It is 10 feet long and 9 feet wide. What is the area of Gina's floor?

Answer:
y = -5x - 3
Step-by-step explanation:
To answer this the slope must be clculated first
slope equation:
[tex]\frac{y2-y1}{x2-x1}[/tex]
these variables symbolize ordered pairs, and the best part is that you can use any two ordered pairs for this example we can use (-5, 10) and (-3,0)
we'll call the first ordered pair 1 so x1 = -5 and y1 = 10.
the next odered pair is 2 so x2 = -3 and y2 = 0.
With this information layed out we can solve:
[tex]\frac{0-10}{-3-(-5)}[/tex]
0 - 10 = -10
-3 - (-5) = 2 --- remember negatives cancel each other out to make a positive
[tex]\frac{-10}{2}[/tex] = -5
the slope of the line is -5. Now the next thing to note is that one of the ordered pair (-3,0) is a y intercept. It's time to introduce the equatione of a line:
y = mx+b
There are other equations that can be used for a line but with the info given this equation best suits the data.
m = slope
y and x = are the ordered pair you can input into the equation to slove
b = the y intercept
So the equation would be:
y = -5x - 3

For finding the surface area of the entire cylinder, we need to use the proper formula which is [tex]SA = 2 \pi r h + 2 \pi r^2[/tex]. Since the problem already gives us the radius and height, we can easily plug in the numbers. The equation should now look like this: [tex]SA = 2 * 3.14*3*6 +2*3.14*3^2[/tex].
After multiplying and adding all the numbers in the formula, we get a surface area of 169.56 yards squared.
For the lateral surface area, we can just subtract the [tex]2 \pi r^2[/tex] part from the formula.
[tex]SA = 2 * 3.14* 3 *6[/tex], which is 113.04 yards squared for the lateral surface area.

Use the Pythagorean theorem to find the value of b²
So what is the Pythagorean Theorem:
⇒ it states the sum of both leg's lengths squared is equal to
⇒ hypotenuse's length squared
(look at the image attached for a better explanation)
To find out [tex]b^2[/tex], let's look to the Pythagorean equation to see what we are missing:
[tex]a^2 + b^2 = c^2\\(10^2) + b^2 = 325\\b^2 = 325 - 10^2\\b^2 = 325 - 100 = 225\\b^2 = 225[/tex]
a = 10 ⇒ [tex]a^2[/tex] = 100[tex]c^2 = 325[/tex]So b^2 = 225 ⇒ Choice B

because angles a is diagonally opposite to 162, they are equal. And as b and 162 are alternate angles, they will also be equal
Answer:
C. <A & <B
Explanation:
If lines m and n are parallel, then you can use the proofs of vertical angles are congruent and alternate interior angles are congruent to prove that <A and <B are equal to 162 degrees; the reason that <C and <D are not congruent, is because they would be too small to fit 162 degrees, they would be the opposite of 162 which is 180-162=18 degrees.
Paul ate 7/9 of 1/6 of his birthday cake. Did Paul eat more or less than 7/9 of the cake? Did he eat more or less than 1/6 of the cake? Explain your answer WITHOUT finding the exact product in the space below.
Answer:
See below ↓↓
Step-by-step explanation:
He ate less than 7/9 of the cakeHe ate less than 1/6 of the cakeTo understand, I'll explain in simple words.
First look at the part where it says 1/6 of his birthday cakeThat means he can only eat less than or equal to 1/6 of the cake7/9 > 1/6, so it's definitely less than 7/9Now, it says he ate 7/9 of that 1/6 slice of the cakeThe 1/6 slice can be represented as a whole (9/9) and he only ate 7 parts of that small fractionTherefore, he ate less than 1/6 of the cakeI hope it's clear and feel free to ask if you're still confusedThe vertices of triangle ABC are A(-2, 3), B)4, 3), and C(-2, -4).

x=6
is a solution to the inequality x−5≤ 10
True or False?
Answer:
[tex]\boxed{\sf{FALSE}}[/tex][tex]\boxed{\sf{x\leq 15}}[/tex]Step-by-step explanation:
Isolate the term of x from one side of the equation.
x-5≤10First, add by 5 from both sides.
[tex]\sf{x-5+5\leq10+5}[/tex]
Solve.
Add the numbers from left to right.
[tex]\sf{10+5=15}[/tex]
[tex]\Longrightarrow: \boxed{\sf{x\leq 15}}[/tex]
Therefore, the solution is x≤15, which is our answer.I hope this helps you! Let me know if my answer is wrong or not.
Let's solve this inequality.
First, we should add 5 to both sides:-
x≤10+5
x≤15
Remember, the "≤" sign means "less than or equal to"
So is x=6 a solution to the inequality x≤15? Will this solution make the inequality true?
Yes.
note:-Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)

Answer:
m1=35
m2=77
m3=49
m4=77
m5=62
m6=28
Step-by-step explanation:
The required angles are ∠ 1 = 35°, ∠ 2 = 77°, ∠ 3 = 49°, ∠ 4 = 77°, ∠ 5 = 62° and ∠ 6 = 28°
What are angles?An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes.
Given is a figure, we need to find the marked angles from it,
∠ 2 + 103° = 180° [linear pair]
∠ 2 = 77°
∠ 1 + ∠ 2 + 68° = 180° [angle sum property of a triangle]
∠ 1 = 35°
∠ 4 = ∠ 2 [vertically opposite angles]
∠ 4 = 77°
Now,
∠ 3 + 41° = 90° [angles in a right triangle]
∠ 3 = 49°
∠ 6 = 180° - (∠ 3+103°)
∠ 6 = 28°
∠ 5 = 90°-∠ 6
∠ 5 = 62°
Hence, the required angles are ∠ 1 = 35°, ∠ 2 = 77°, ∠ 3 = 49°, ∠ 4 = 77°, ∠ 5 = 62° and ∠ 6 = 28°

Answer:
5(2+y)
Step-by-step explanation:
The sum of 2 and y = 2+y
So,
5 times the sum of 2 and y(2 + y) = 5 × (2+y) = 5(2+y)
The answer is 5(2+y)
Answer:
A. 3(2 + y)
Step-by-step explanation:
It's A. 3(2 + y) because when an equation is in parentheses then you have to do it first. So you would work out 2 + y and then multiply it by 3.
