What number must you add to complete the square?<br><br> x^2-10x=46
gtnhenbr [62]
X² - 10x = 46
10/2 = 5; 5²+ 25 add 25 to both sides

x² - 10x + 25 = 46 + 25

so the number you have to add to complete the square is 25.

Answer:

see explanation

Step-by-step explanation:

The solutions to the systems of equations are at the points of intersection of the 2 graphed functions.

1

There are 2 points of intersection , so 2 solutions at

(0, - 3 ) and (4, 5 )

2

There is 1 point of intersection, so 1 solution at

(- 2, 5 )

3

There are no points of intersection , so no solution

The order of operations used throughout mathematics, science, technology and many computer programming languages is expressed here:[2] 

<span>exponents and roots </span>
<span>multiplication and division </span>
<span>addition and subtraction </span>

<span>This means that if a mathematical expression is preceded by one operator and followed by another, the operator higher on the list should be applied first. The commutative and associative laws of addition and multiplication allow terms to be added in any order and factors to be multiplied in any order, but mixed operations must obey the standard order of operations. </span>

<span>It is helpful to treat division as multiplication by the reciprocal (multiplicative inverse) and subtraction as addition of the opposite (additive inverse). Thus 3/4 = 3 ÷ 4 = 3 • ¼; in other words the quotient of 3 and 4 equals the product of 3 and ¼. Also 3 − 4 = 3 + (−4); in other words the difference of 3 and 4 equals the sum of positive three and negative four. With this understanding, we can think of 1 − 3 + 7 as the sum of 1, negative 3, and 7, and add in any order: (1 − 3) + 7 = −2 + 7 = 5 and in reverse order (7 − 3) + 1 = 4 + 1 = 5. The important thing is to keep the negative sign with the 3. </span>

<span>The root symbol, √, requires a symbol of grouping around the radicand. The usual symbol of grouping is a bar (called vinculum) over the radicand. Other functions use parentheses around the input to avoid ambiguity. The parentheses are sometimes omitted if the input is a monomial. Thus, sin x = sin(x), but sin x + y = sin(x) + y, because x + y is not a monomial. Calculators usually require parentheses around all function inputs. </span>

<span>Stacked exponents are applied from the top down, i.e., from right to left. </span>

<span>Symbols of grouping can be used to override the usual order of operations. Grouped symbols can be treated as a single expression. Symbols of grouping can be removed using the associative and distributive laws, also they can be removed if the expression inside the symbol of grouping is sufficiently simplified so no ambiguity results from their removal. </span>

Given the following absolute value function find the range. ƒ(x) = |x + 5| - 8
balandron [24]
The result of an absolute value operation is never negative. So the smallest that the expression |x+5| can be is 0. 

Tacking on "-8" to |x+5| leads to |x+5|-8

The range of this is [-8, infinity) since the smallest |x+5|-8 can be is -8. All I did was subtract 8 from the smallest value of |x+5|

Final Answer: choice C)
