I need help with this math problem!!

Vesnalui [34]

In order to find which one is or isn't, you need to solve for the value of 'x'.
2x + 15 = 35
2x = 20
x = 10

Substitute x =10, into equation. If each side are not the same (i.e. 0=2), then that's the equation that is not equivalent,

Answer is B
Double check this. Chur! :)

Hope this makes sense.

F(x)= −x^2+10x−6 Find f(−5)

Nina [5.8K]

Answer:

f(-5) = -81

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

Algebra I

Function Notation

Step-by-step explanation:

Step 1: Define

f(x) = -x² + 10x - 6

f(-5) is x = -5

Step 2: Evaluate

Substitute: f(-5) = -(-5)² + 10(-5) - 6
Exponents: f(-5) = -(25) + 10(-5) - 6
Multiply: f(-5) = -25 - 50 - 6
Subtract: f(-5) = -75 - 6
Subtract: f(-5) = -81

explain why the function f(x)= 5x-15/x-3 is not asymptotic to the line x=3. sketch the graph of this function.

Katyanochek1 [597]

X=3 is a vertical line . The question is "Is this line a vertical asymptotefor the function f(x)?". Vertical asymptote is vertical line near which the function grows without bound.
The function f(x)=5x-15/x-3 is not asymptotic to the line x=3, because for x=3 f(x)=5*3-15/3-3=0/0=0 . So, there is a value for x=3 and the function f(x) does not grow near x=3 without bound.

DOES THE GRAPH OF THE STRAIGHT LINE WITH SLOPE OF 4 AND Y-INTERCEPT OF -3 PASS THROUGH THE POINT (-2, 9)

lisov135 [29]

Equation of the given line will be :

y = 4x - 3

now, let's plug the value of x as the x - coordinate of the above point (-2 , 9) to check whether it lies on the line or not.

$y = 4( - 2) - 3$

$y = - 8 - 3$

$y = - 11$

now, since value of isn't equal to the y - coordinate of the given point, so the point doesn't lies on the line.

Step-by-step explanation:

Which expression is equivalent to -6 - (-2); minus, 6, minus, left parenthesis, minus, 2, right parenthesis? Choose 1 answer: Choose 1 answer:

(Choice A) A -6+2; minus, 6, plus, 2

(Choice B) B 2+6; 2, plus, 6 (Choice C) C -6+(-2); minus, 6, plus, left parenthesis, minus, 2, right parenthesis

(Choice D) D -2 + 6

Given expression:

-6 - (-2)

Note:

- * - = +

+ * + = +

- * + = -

+ * - = -

-6 - (-2)

= -6 + 2

= -4

The correct answer is (Choice A) A -6+2; minus, 6, plus, 2
