Answer:

5% increase

Step-by-step explanation:

last Summer was 20° , this Summer is 21° so is 1° more so the question is what is the increase 1° of 20

20° is to 100% as

   1° is to ?%

cross multiply

?% *20 =1*100

divide by 20 both sides

Quick! 8 points! best answer is brainiest!
Novosadov [1.4K]
What I understand from the picture given, she had 2 ribbons with the length of 1/4. 
These would be the two shortest ones. 
So: 1/4 + 1/4 = 2/4
      = 1/2

I hope this helps and I know that it is different to what HimyBrainy put but it is what I understood! :/

What is the degree of polynomial?<br>With example!​
Inessa [10]

Answer:

\boxed{\mathfrak{Question ~}}

What is the degree of polynomial?

\large\boxed{\mathfrak{Answer}}

The degree of a polynomial is the highest of the degrees of the polynomial's monomials with non-zero coefficients.

Example:

{6x}^{4}  +  {2x}^{3}  + 3

4x The Degree is 1 (a variable without an

exponent actually has an exponent of 1)

More Examples:

4x^ − x + 3 The Degree is 3 (largest exponent of x)

x^2 + 2x^5 − x The Degree is 5 (largest exponent of x)

z^2 − z + 3 The Degree is 2 (largest exponent of z)

A constant polynomials (P(x) = c) has no variables. Since there is no exponent to a variable, therefore the degree is 0.

3 is a polynomial of degree 0.

Which equation represents a linear function rule for the following set of ordered pairs?
d1i1m1o1n [39]

The equation that represents the linear function for the set of ordered pairs is: A. y = -3x + 2.

<h3>What is the Equation of a Linear Function?</h3>

Equation of a linear function, where m is the slope and b is the y-intercept, is expressed as y = mx + b.

Find the slope (m):

Slope (m) = change in y/change in x = (-7 -(-4)) / (3 - 2)

Slope (m) = -3/1 = -3

Find b by substituting m = -3 and (1, -1) = (x, y) into y = mx + b:

-1 = -3(1) + b

-1 = -3 + b

-1 + 3 = b

2 = b

b = 2

Substitute m = -3 and b = 2 into y = mx + b

y = -3(x) + 2

y = -3x + 2

Therefore, the equation that represents the linear function for the set of ordered pairs is: A. y = -3x + 2.
