Step-by-step explanation:
A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.

Answers
Answer: x-intercept: y = -7
y-intercept: x = -5
Step-by-step explanation:
Rearrange to standard format: y=mx+b
-7x-5y=35
-5y= +7x + 35
y= -(7/5)x -7
b is the y-intercept b=-7
--
Find a value for x that makes y = 0, the x-intercept.
y= -(7/5)x -7
0= -(7/5)x -7
(7/5)x = -7
(5/7)*(7/5)x = (5/7)*(-7)
x = -5, the y-intercept

Answer:
40° and 140°
Step-by-step explanation:
let one angle be x then the other is 3.5x
A linear pair sum to 180° , then
x + 3.5x = 180
4.5x = 180 ( divide both sides by 4.5 )
x = 40 and 3.5x = 3.5 × 40 = 140
The angles are 40° and 140°

Solve the inequality -5/2 (3x-2)<6-2x. For full credit, you will need to show and explain every step. You may add more lines if you need them
Answers
Answer: Answer: x> -2/11
Step-by-step explanation: Multiply both sides of the inequality by the least common denominator: 2 (-5/2(3x-2))<2x6-2x2x
Reduce the expression to the lowest term: -5(3x-2)<2 x 6-2 x 2x
Apply Multiplicative Distribution Law: -15x + 10< 2 x 6 -2 x 2x
Multiply the monomials:-15x + 10< 2 x 6 - 4x
Calculate the product or quotient: -15x + 10<12-4x
Rearrange unknown terms to the left side of the equation: -15x + 4x< 12 - 10
Combine like terms: -11x < 12 - 10
Calculate the sum or difference: -11x<2
Divide both sides of the inequality by the coefficient of variable: x > 2 ÷(-11)
Rewrite as fraction: x> 2/-11
Rewrite the fraction: x> -2/11
Answer: x> -2/11
The solution to the inequality is x>-2/11.
The given inequality is -5/2 (3x-2)<6-2x
We need to simplify the given inequality step by step.
How to solve inequality?To solve an inequality, isolate the variable on one side with all other constants on the other side. To accomplish this, perform opposite operations to manipulate the inequality. First, isolate the x by multiplying each side by two. Whatever you do to one side you must also do to the other side.
Now, multiply both sides of the inequality by 2.
That is, -5(3x-2)<2(6-2x)
=-15x+10<12-4x
Add both sides of the inequality by 4x.
That is, -15x+10+4x<12-4x+4x
=-11x+10<12
Subtract 10 on both sides of the inequality.
That is, -11x+10-10<12-10
-11x<2
Divide both sides of the inequality by -11.
x>-2/11
Therefore, the solution to the inequality is x>-2/11.
