Answer:
1
Step-by-step explanation:
x+y = 5
Put this equation in slope intercept form y = mx+b where m is the slope
y = -x +5
The slope of the line is -1
Perpendicular lines have slopes that multiply to -1
-1 * m = -1
m = 1
The slope of the perpendicular line is 1

What is a rational function?
In mathematics, a rational function is any function that can be described by using a rational fraction, which is an algebraic fraction such that each the numerator and the denominator are polynomials. The coefficients of the polynomials need no longer be rational numbers; they'll be taken in any field k.
A rational function is one that can be written as a polynomial divided by a polynomial. for the reason that polynomials are defined everywhere, the domain of a rational feature is the set of all numbers except the zeros of the denominator. example 1. f(x) = x / (x - 3). The denominator has only one 0, x = 3.

Marcia, an experienced bungee jumper, leaps from a tall bridge and falls toward the river below. The bridge is 155 feet above the water and Marcia's bungee cord is 80
feet long unstretched. When will Marcia's cord begin to stretch? Round your answer to two decimal places.
Answer:
Marcia's cord will begin to stretch after [tex]2.24\:\rm{s}[/tex].
Step-by-step explanation:
The expression used to find displacement is given as,
[tex]s=ut+\dfrac{1}{2}at^{2}[/tex]
The initial velocity of Marcia before leaping is zero, so [tex]u=0\:\rm{m/s^{2}}[/tex].
Marcia travels under the influence of gravity and fall freely so the acceleration due to gravity is only acceleration responsible for her movement.
The value for [tex]g[/tex] is [tex]10\:\rm{m/s^{2}}[/tex](approximately) and when it is converted in [tex]\:\rm{ft/s^{2}}[/tex], it is [tex]32\:\rm{ft/s^{2}}[/tex].
Substituting the values, the distance that Marica travels under influence of gravity for [tex]t[/tex] seconds is,
[tex]\begin{aglined}s&=ut+\dfrac{1}{2}at^{2}\\s&=(0)t+\dfrac{1}{2}gt^{2}\\s&=0+\dfrac{1}{2}(32)t^{2}\\s&=16t^{2}\end{aligned}[/tex]
The bungee cord begins to stretch after Marcia has fallen [tex]80\:\rm{ft}[/tex], so
[tex]\begin{aligned}s&=16t^{2} \\80&=16t^{2} \\t^{2} &=5\\t&=2.24\:\rm{s}\end{aligned}[/tex]

Answer:
x = 7y = 12∠TPS = 140°∠TPQ = 40°∠PRS = 50°Step-by-step explanation:
The marked angles at P are a linear pair, so are supplementary:
(5x +5) +(18x+14) = 180
23x = 161 . . . . . . . . . . . . . . subtract 19
x = 7
Those angle measures are ...
∠TPQ = (5·7 +5)° = 40°
∠TPS = (18·7 +14)° = 140°
__
The marked angle at R is the complement of the acute angle at P, so we have ...
3y +14 +40 = 90
3y = 36
y = 12
∠PRS = (3·12 +14)° = 50°

if 325 cases of 24 cans of soup,227 cases of 48 cans of soup . Estimate first.then find how many 12 cans of soup can made a cases?
Answer:
1,558 cases of 12 cans of soup can be made
Step-by-step explanation:
Here, we want to calculate how many cases of cans of soup can be made;
In the first part, we had 325 cases of 24 cans Now, if we split the 24 cans into 2 , we have 12 cans ;
So the number of cases is now 325 * 2 = 650 cases
In the second part, we had 227 cases of 48 cans.
If we split 48 cans into 4 , we can have 12 cans.
So the new number of cases here become 227 * 4 = 908 cases.
So the total number of cases we have will be; 908 + 650 = 1,558 cases

The line y=px+2 is parallel to the line 2x+y=5. Determine the value of p
Answer:
-2
Step-by-step explanation:
The line y=px+2 has slope p
The line 2x+y=5 can be rewritten as y =-2x+5 so it has slope -2.
Since the two are parallel then they must have the same slope. Hence p=-2.
Answer:
p = - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x + y = 5 ( subtract 2x from both sides )
y = - 2x + 5 ← in slope- intercept form
with slope m = - 2
Parallel lines have equal slopes
Thus for y = px + 2 to be parallel to y = - 2x + 5
Then p = - 2

A -1
B 2
C 1
D 0
(sin²(x) - 1)/cos(x) = -1
-cos²(x)/cos(x) = -1
-cos²(x) = -cos(x)
cos²(x) - cos(x) = 0
cos(x) (cos(x) - 1) = 0
Then it follows that cos(x) = 0 or cos(x) = 1. But if cos(x) = 0, then the original expression on the left side of the equation would be undefined. Then C is the only valid solution.

91 more than the square root of a number
Answer:
Step-by-step explanation:
y = x 2 + 91
Explanation:
Let the number be x
, then Square of the number is x ^2
91 more than the square of a number" will be x^ 2 + 91
So, we can write it as an algebraic expression with two variables as :
y = x ^2 + 91

Step-by-step explanation:
JL = JK + KL
first get value of x:

therefore,
[tex]KL = 3x + 7 \\ = (3 \times 1) + 7 \\ = 3 + 7 \\ = 10[/tex]

Answer:
The sum is 17,690 nine
Step-by-step explanation:
8₉ + 2₉ = (10)₉ = (9 + 1)₉ = 11₉
4₉ + 4₉ + 1₉ = (9)₉ = (9 + 0)₉ = 10₉
8₉ + 8₉ + 1₉ = (17)₉ = (9 + 8)₉ = 10₉ + 8₉ = 18₉
8₉ + 8₉ + 1₉ = 18₉
So
8848₉ + 8842₉ = 18801₉

Step-by-step explanation:
You have to be assured that x really is even. In this case (and the question has a flaw in it) , you assume that x is even. Normally you would multiply x by 2 to get 2x. Now you know it is even, but it is the number not required of you.
So we will assume it is even.
