Find the slope and y-intercept of the line. y=-x+7

Mathematics
1 answer:
musickatia [10]3 years ago
4 0

Answer:

slope = - 1, y- intercept = 7

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 )

y = - x + 7 ← is in slope- intercept form

with slope m = - 1 and y- intercept c = 7

Chris cut a rope into two pieces. One piece was 11.36 meters long and the other piece was 13.46 meters long. About how long was
rosijanka [135]
If you would like to know about how long was the rope before Chris cut it and you would like to round each length to the nearest tenth to estimate the total length of the original piece of rope, you can calculate this using the following steps:

11.36 meters = 11.4 meters
13.46 meters = 13.5 meters

11.4 + 13.5 = 24.9 meters

Result: The rope was 24.9 meters long (before Chris cut it) - rounded to the nearest tenth.

Select from the matches below to correctly complete the statements. I'll give brainliest to someone with correct answer!
Aneli [31]

Answer:

<h3>The correct matches as follows :</h3>

1) The product of a linear monomial and a linear monomial is a - quadratic monomial

2) The product of a quadratic monomial and a quadratic trinomial is a - quartic trinomial

3) The product of a linear monomial and a linear binomial - Quadratic binomial

Step-by-step explanation:

The correct matches as follows :

1) The product of a linear monomial and a linear monomial is a - quadratic monomial

<h3> Monomial is a linear expression having only term with degree 1 (variable)</h3>
  • For Example : Let x and y be two monomials which is linear
  • If we product the two linear monomials we get
  • x\times x=x^2 which is a quadratic monomial

2) The product of a quadratic monomial and a quadratic trinomial is a - quartic trinomial

<h3>For example : Let x^2 be the Quadratic monomial has one term with degree 2 and x^2+2x+3 be the quadratic trinomial ( has 3 terms with degree) </h3>
  • If we product the quadratic monomial and quadratic trinomial we have
  • x^2\times (x^2+2x+3)=x^2(x^2)+x^2(2x)+x^2(3)
  • =x^4+2x^3+3x^2
  • Therefore x^2(x^2+2x+3)=x^4+2x^3+3x^2 which is a quartic trinomial has degree 4 with three terms

3) The product of a linear monomial and a linear binomial - Quadratic binomial

<h3>For example : Let x be the linear monomial and x^2+5 be the linear binomial has two terms with degree 1</h3>
  • If we product the linear monomial and quadratic binomial we get
  • x\times (x+5)=x(x)+x(5)
  • =x^2+5x
  • Therefore x\times (x+5)=x^2+5x which is a quadratic binomial with degree 2
