We know that :
Ф Product of the slopes of two lines perpendicular to each other should be equal to -1
Let the slope of the line perpendicular to given line be : M
Given equation of the line : y = -1/2x + 4
This line is in the form : y = mx + c, where m is the slope and c is the y intercept
Comparing with y = mx + c :
we can notice that slope of the given line is -1/2
⇒ M × -1/2 = -1
⇒ M × 1/2 = 1
⇒ M = 2
Answer : Slope of the line perpendicular to given line is 2
7x-5y=15
solve for y, please help
Answer:
7x-15/5
Step-by-step explanation:
Given :-
A linear equation in two variable is given to us . That is 7x - 5y = 15.And , we need to solve for y in terms of x . So taking the given equation ,
[tex]:\implies[/tex] 7x - 5y = 15
[tex]:\implies[/tex] -5y = 15 - 7x
[tex]:\implies[/tex] 5y = 7x - 15
[tex]:\implies[/tex] y = ( 7x - 15)/5
Hence the required answer is 7x-15/5.tep Looking at the powers of 3 shown, it is clear that each power may be found by multiplying the previous power by 3. Or you can also see that each power may be found by dividing the power after it by 3. Using this pattern, what must 31 equal?

(b) Give the equation of a line which is parallel to line y=2x and
passes through (0,3).
All lines parallel to y=2x-3 will have the same slope as y=2x-3. So how do you find the slope of y=2x-3? Very simple! When written in slope-intercept form you simply look at the coefficient of the ‘x’ term. In this instance the coefficient is 2. Therefore any equation that has a slope of 2 will be parallel to y=2x-3. In general we can say that the family of equations parallel to y=2x-3 is y=2x+b where b is the y-intercept.
Write the equation of this line from the table provided.
SOMEONE PLEASE HELP ASAP I WILL GIVE YOU BRAINLIEST!!!
Answer:
y=2x-1
Step-by-step explanation:
If you are supposed to write the equation in slope-intercept format, (y=mx+b), then y=2x-1 would be the answer. 2 is the slope(m), and -1 is the y-intercept(b). I hope thus helped :).

If tan0 = 3/4, find sin0
Answer:
b
Step-by-step explanation:
Answer:
[tex]\text{b. }\sin \theta =\frac{3}{5}[/tex]
Step-by-step explanation:
In a right triangle only, the tangent of an angle is equal to its opposite side divided by its adjacent side. If [tex]\tan \theta =\frac{3}{4}[/tex] as given in the problem, then the opposite side of angle theta is 3 and its adjacent side is 4. Thus, the hypotenuse of the triangle must be [tex]h=\sqrt{4^2+3^2}=\sqrt{25}=5[/tex].
The sine of an angle in a right triangle is equal to its opposite side divided by its hypotenuse. Therefore, [tex]\sin \theta =\frac{3}{5}[/tex] (o/h).
Is knowing the coordinates of the vertex of a parabola enough to determine the domain and range? a. No: we would have no information about the domain. c. Yes: if the vertex is at (m,n), then the domain is all reals and the range is y ≤ n. b. No: we would need to know if the vertex is a minimum or a maximum. d. Yes: if the vertex is at (m,n), then the domain is all reals and the range is y ≥ n.

Step-by-step explanation:
Joseph runs 2 miles on Monday. Each day after that, he runs the same 1 1/3 mile route every
morning. His goal is to run at least 6 miles by the end of the week.
Which inequality represents the least number of days after Monday that Joseph needs to run
to reach his goal? *
Answer:
2 + 1 1/3x ≥ 6
x ≥ 3 days
Step-by-step explanation:
Monday = 2 miles
Other days = 1 1/3 miles
x = least number of days after Monday that Joseph needs to run
to reach his goal
Total miles = 6 miles
The inequality is
2 + 1 1/3x ≥ 6
1 1/3x ≥ 6 - 2
1 1/3x ≥ 4
4/3x ≥ 4
Divide both sides by 4/3
4/3x ÷ 4/3 ≥ 4 ÷ 4/3
x ≥ 4 × 3/4
x ≥ 3 days
A rectangular prisim has a base with an area of 200cm squared. The volume of the prism is 3,000cm cubed. What is the height of the prism?
Answer:
[tex]Height = 15cm[/tex]
Step-by-step explanation:
Given
[tex]Base\ Area = 200cm^2[/tex]
[tex]Volume = 3000cm^3[/tex]
Required
The height
Volume is calculated as:
[tex]Volume = Base\ Area * Height[/tex]
Make Height the subject
[tex]Height = \frac{Volume}{Base\ Area}[/tex]
This gives
[tex]Height = \frac{3000cm^3}{200cm^2}[/tex]
[tex]Height = \frac{3000}{200}cm[/tex]
[tex]Height = 15cm[/tex]
What is the total area, in square feet, of the house and backyard? A) 200 B) 400 C) 4,000 D) 5,200
Answer:
Area = 5200 ft²
Step-by-step explanation:
First let us find the area of the house.
Area = l × w
Area = 30 ft × 40 ft
Area = 1200 ft²
Now let us find the area of the backyard.
Area = l × w
Area = 80 ft × 50 ft
Area = 4000 ft²
Now that we have found the area of the house and the backyard, it asks us to find the total area of house and the backyard. To find the answer, you will both, the area of house and the area of the backyard.
Area of house + Area of backyard
1200 ft² + 4000 ft²
5200 ft²
Hope this helps, thank you :) !!

male female eats oysters 205 113 does not eat oysters 98 322 what is the probability that one of the people chosen from this survey was a female and does not eat oysters could someone explain?
Answer:
322 /738 ; 0.436
Step-by-step explanation:
__________________ M____ F__
Eat oysters ________ 205 __ 113
Does not eat oysters _ 98 __ 322
Probability of choosing a female and does not eat oysters :
Number of (F n Does not eat oyster) = 322 (from table)
Total number of sample : (205+98+113+322) = 738
Hence,
Probability of choosing a female and does not eat oysters ;
Number of (F n Does not eat oyster) = 322 (from table) / total number of samples
= 322 / 738
= 0.436
