Divide both sides by 4
n = q - w
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

Find cos(x) if [tex]\frac{sin^2x-1}{cosx} =-1[/tex].
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.

Answer:
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.

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

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
6) A cube has a volume of 125 mm3, what is its surface area?

r³ = 125
r = 5 mm
...
V = 5³
V = 125 mm³
...
A = 6 . s²
A = 6 . 5²
A = 6 . 25

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

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.
