algebraic expression the sum of 12 and k
What are the values of a and b, and what is an equation for the line?
Answer:
a = 1, b = 6
Step-by-step explanation:
slope of line = (5-2) / (12-3) = 3/9 = 1/3
(3-2) / (b-3) = 1/3
b-3 = 3 b = 6
(2-a) / (3-0) = 1/3
2-a = 1 a = 1

y is an irrational number between 3 and 4 . what is the value of y
Answer:
If a and b are two positive rational numbers such that ab is not a perfect square of a rational number, then ab is an irrational number lying between a and b.
So an irrational number between 3 and 4 is=3×4=3×4=3×2=23
For which value of m is start fraction 4 over 16 end frction equals start fraction m over 24 end fraction a proportion? A. m = 6 B. m = 8 C. m = 12 D. m = 14
Answer:
A. M=6
Step-by-step explanation:
Basically, this question is asking you to find m if 4/16 = m/24.
First, 4/16 can be simplified to 1/4. This will make it easier to solve.
You now have 1/4 = m/24.
Multiply both sides by 24 to get 24/4 = m.
Simplify to get m = 6.

Thankss + BRAINLIST only for correct answer
Answer:
(2,0)
Step-by-step explanation:
2x-y=4
Substitute x with 2, and y with 0.
2(2)-0=4
2 multiplied to 2 is 4, then subtracted to 0 would be 4, thus it is correct.
3x-y=6
Substitute x with 2, and y with 0.
3(2)-0=6
3 multiplied to 2 is 6, then 6 subtracted with 0 is 6, thus it is correct.

In the triangle below, ∠Q is a right angle. Which ratio would be equivalent to the ratio of sin∠R?
a) cos∠Q
b) cos∠S
c) sin∠Q
d) sin∠S
Answer:
b) cos∠SStep-by-step explanation:
sin ∠R = SQ/SR
This is same as:
cos SCorrect option is b)
cos<Q
Lets do
[tex]\\ \sf\longmapsto sin<R=\dfrac{P}{H}[/tex]
[tex]\\ \sf\longmapsto sin<R=\dfrac{SQ}{SR}[/tex]
Now
[tex]\\ \sf\longmapsto cos<Q=\dfrac{B}{H}[/tex]
[tex]\\ \sf\longmapsto cos<Q=\dfrac{SQ}{SR}[/tex]

10) What is the area of the figure below? Round your answer to the nearest tenth (1 place
value) if needed.
Answer:
Step-by-step explanation:
Divide the figure into a rectangle and a triangle.
area of rectangle = 5×10 = 50 square units
area of triangle = 0.5×5×10 = 25 square units
total area = 50+25 = 75 square units
