What is the equation of the line parallel to line l that passes through point (3,3)
Answer:
Step-by-step explanation:
Let the equation if the line be y = mx + c
since the line is parallel to y = (smt-your question isn't complete), their gradients/slope must be the same (aka m = __)
sub (3, 3):
3 = __(3) + c
c = __
therefore, the equation of the line is y = __x + __

the velocity of a falling body varies directly as the time of flight if the velocity of the falling body at the end of two seconds is 64.4ft/s find the velocity at the end of 5 seconds
Answer:
Step-by-step explanation:
If the velocity of a falling body varies directly as the time of flight, this is expressed as;
v α t
v = kt
k = v/t
If at t = 2secs, v = 64.4ft/s
k = 64/2
k = 32 ft
To get the velocity at the end of 5 secs, we will say;
at t = 5secs v = ?
From the formula;
v = kt
v = 32(5)
v = 160ft/s
Hence the required velocity is 160ft/s

7x = 49
-4x= -40
x/2 = 6
x/9 = -2
Answer:
71012-18Step-by-step explanation:
For 7x = 49 you need to divide 7 to both sides
For -4x=-40 you need to divide -4 to both sides
For x/2 = 6 you need to multiply 2/1 to both sides
For x/9 =- 2 you need to multiply 9/1 to both sides

Step-by-step explanation:
You would have to look up how to do the hadn written way of figuring out this but I just used my calculator. To do this with your TI-84 or newer calculator, press "stat" and go into "edit". You will see some columns with the names "L1, L2, L3, etc." which stand for lists. put your x values in "L1" and their corresponding y values next to them in "L2". When you're done press stat again and move right to the heading "Calc". Go down to number 4 which should say "LinReg(ax+b)" next to it and press enter. now you should see "Xlist" and "Ylist" with "L1" and "L2" beside them respectively. Once that is set, go down to "Calculate" and press enter and it should give you slope intercpet form and what "a" and "b" are. You're welcome.~ ;P

The perimeter of a triangle is 43 inches. The second side is 4 times as long as the first side. The third side is 1 inch longer than the first side. What is the length of each side
Answer:
First side=7
Second side =28
Third side =8
explanation:
Perimeter of a triangle is the sum of the length of the sides of the triangle. Given that the perimeter of the triangle = 43 inches
Second side is 4 times the first side
Third side is 1 inch longer the first
Let's call the first side x
Then equation for the perimeter of the triangle is given by
x+4x+x+1=43
We solve for x
6x+1=43
6x=43-1
6x=42
x=42/6
x=7
Therefore the first side x=7, the second side is 4x= 4*7=28, third side= 1+x= 1+7=8

Two angels of a triangle measure 12 and 40.
What is the measure of the third angle of the triangle ?
Answer:
C) 128
Step-by-step explanation:
Sum of all three angles of triangle = 180
Let the third angle be 'x'
x + 12 + 40 = 180
x + 52 = 180
x = 180 - 52
x = 128

As soon as a new car is purchased and driven away from the dealership, it begins to lose its value, or depreciate. Alonso bought a 1994 Plymouth Neon for $9559. One year later, the value of the car was $8500. What was the percent of decrease of the value of the car?
P.S. This is a percent increase/decrrease
from: 9559
to: 8500
%/100 = differences of to and from/ from ( before the number )
( no negative difference, bigger number subtract smaller number)
Answer:
11%
Step-by-step explanation:
$9559-$8500=1059
1059/9559= .110786
.110786 x 100= 11.0786%
11.0786%= 11%

One factor of f(x) = x3 − 14x2 + 61x − 84 is (x − 7). What are the zeros of the function?
Answer:
-7
Step-by-step explanation:
Because zero is the x, so x=-7 then it's -7
The zeros of the polynomial function is x = 7, x = 3, and x = 4 if one factor of f(x) = x³ − 14x² + 61x − 84 is (x − 7).
What is a polynomial?Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
It is given that:
f(x) = x³ − 14x² + 61x − 84
One factor is (x - 7)
The cubic polynomial can be written as:
f(x) = (x - 7)(x² - 8x + 12)
Or
f(x) = (x - 7)(x - 3)(x - 4)
To find the zeroes equate to zero:
f(x) = 0
(x - 7)(x - 3)(x - 4) = 0
x = 7, x = 3, and x = 4
Thus, the zeros of the polynomial function is x = 7, x = 3, and x = 4 if one factor of f(x) = x³ − 14x² + 61x − 84 is (x − 7).

Step-by-step explanation:
If it's 9.5 times the sum of 10 and 5/4, the answer is A.
Its not b because its called 10 plus 9.5 times 5/4.
Its not c because it is called 9.5 PLUS the sum of 10 and 5/4.

it takes Louis 1 2/3 hours to write 5/6 of a short story how long will it take louis to complete the story?
Answer:
2 hours to write the story.
1/3 of an hour remaining to complete the story.
20 minutes remaining.
(Read the explanation for further details.)
Step-by-step explanation:
1.Based on the given information, set up an equation;
(1 2/3) hours ; (5/6) story
Convert to improper fractions;
(1 2/3) ; (5/6)
(5/3) ; (5/6)
2. Solve;
(5/3) ; (5/6)
divide both sides by (5/6)
(5/3) ; (5/6)
/(5/6) /(5/6)
Dividing a fraction is the same as multiplying by its reciprocal
(5/3)/(5/6) ; (5/3)/(5/3)
(5/3)*(6/5) ; (5/3)*(3/5)
2 ; 1
2 hours; 1 story
3. Solve for the time remaining;
Subtract the amount of time elapsed from that total amount of time
total time - time used
2 hours - 1 2/3 hours
Convert to improper fractions
2 - 5/3
1/3 hour
Convert to minutes
20 minutes
