Consider the line 4 x + 9 y = 8 . What is the slope of a line parallel to this line? What is the slope of a line perpendicular to this line?
Answer:
Parallel line: -4/9 Perpendicular line: 9/4
Step-by-step explanation:
This linear equation is written in standard form: Ax + By = C. First, we isolate the y variable to get the equation: y = -4/9x + 8/9. Now we notice that the slope of this line is -4/9. Parallel lines have the same slope, so the slope of the line parallel to this one is also -4/9. The slope of a perpendicular line is the negative reciprocal of the slope of this line, so the slope of a perpendicular line is 9/4.
a right triangle has 13 and 8 feet long each find the length of the hypotenuse
Answer:
15.26
Step-by-step explanation:
By using a^2+b^2=c^2, we can plot the numbers into the equation, 8^2+13^2=c^2. Then answering the exponents, it will equal 64+169=c^2. Add that together to get 233=c. Lastly, we have to square-root 233, which equals 15.26. Hope this helped!

A blockbuster movie makes about $352,000,000 in the United States during its opening weekend. The same weekend another movie opens but only makes about $4,800,000.
What is the combined revenue for the movies? Write your answer in scientific notation.
The combined revenue for the movies in scientific notation is [tex]\$ 3.568 \times 10^8[/tex].
The given parameters;
first revenue made from the movie, = $352,000,000second revenue made from the movie, = $4,800,000The combined revenue from the movie is calculated by adding the two revenues together as shown below;
Total revenue = $352,000,000 + $4,800,000
Total revenue = $356800000 = [tex]\$ 3.568 \times 10^8[/tex]

A baker had 3 1/4 pounds of apples. she used 3/4 to make an apple pie. How many pounds of apples does she have left
Answer:
2 1/2
Step-by-step explanation:
3 1/4 - 3/4 =2.5 which simplify's to 2 1/2
The number of pounds of apples that she has left will be 13/16 pounds.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
A baker had 3 ¹/₄ pounds of apples. she used 3/4 to make an apple pie.
Convert the mixed fraction number into a fraction number. Then we have
3 ¹/₄ = 13/4
The number of pounds of apples that she has left will be given as,
⇒ 13/4 - (13/4)(3/4)
⇒ 13/4 - (39/16)
⇒ (52/16) - (39/16)
⇒ (52 - 39) / 16
⇒ 13/16 pounds
The number of pounds of apples that she has left will be 13/16 pounds.
