identify the relationship between angles f, b, and a in the above diagram. PLEASE HELP WILL GIVE BRAINLIEST 7TH GRADE MATH

Answers

Answer:

Just remember that straight lines are always 180° (a + b = f)

Step-by-step explanation:

Assuming the triangle is equiangular and equilateral, a b and c are the same, so they are interchangeable.

f + c = 180 becuase it is a straight line. you can switch out c with a because they are the same. So:

f+a=180

(switch out with b)

f+b=180

GUESSING this is equiangular, a and b must add up to 120 because they are are both 60.

If a line is 180 degrees and c is 60 (same as a and b) then f will be 180-60 which is 120. 120 is the same as the sum of a and b, so you could write:

a + b = f

The relationship between angles f, b, and a could be as a + b = f.

What is linear pair?

Linear pair of angles are produced when two lines intersect each other at a point. The sum of angles of the linear pair is always 180 degrees.

WE can see that the triangle is equiangular and equilateral, Also angles a b and c are the same, so they are interchangeable.

WE know that the base makes the straight line

f + c = 180

So: f + a = 180

Similarly

f + b = 180

Assuming this is equiangular, a and b must be add to 120, they are both 60 degrees

If we consider the line is 180 degrees and c is 60 then f will be 180-60 which is 120.

120 degree is the same as the sum of a and b, so we could write:

a + b = f

Hence, the relationship between angles f, b, and a could be as a + b = f.

A line with a slope of -4 passes through the point (0, 0). What is its equation in
slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer: y = -4x

Step-by-step explanation: You would use the formula y = mx + b to solve your problem. When you plug the numbers in, you get y = -4x. There would be no "+ b" because in this case, the y-intercept (b) is equal to zero. Therefore, you would not need to write "y = -4x + 0" because that would not be the equation in its simplest form.

A vending machine has $50.40 in it. There are 432 coins total and the machine only accepts nickels and quarters. How many nickels and quarters are in the machine?​

Answers

Nickels = n
Quarters = q

n + q = 432

Nickels are 5 cents (0.05)
Quarters are 25 cents (0.25)

0.05n + 0.25q = 50.40

Use substitution or elimination (I like substitution)
n + q = 432 means n = 432 - q

So 0.05n + 0.25q = 50.4 is
0.05(432 - q) + 0.25q = 50.4
21.6 - 0.05q + 0.25q = 50.4
21.6 + 0.2q = 50.4
0.2q = 28.8
q = 144

Plug in to find nickels
n + q = 432 means
n + 144 = 432
n = 288

Answer:

  see attached

Step-by-step explanation:

There are several possible ways to describe the "type" of a polynomial. Here, since there is a separate column for "degree", we assume that "type" refers to the number of terms.

Polynomials with 1, 2, or 3 terms are called, respectively, monomial, binomial, and trinomial. The first two expressions listed have 1 term only, so are monomials. The last expression has 3 terms, so is a trinomial.

__

The coefficients are the constant multiplier of the term. Some say a "constant", such as the -8 in the last expression, is not considered a coefficient, because there are no variables that it is multiplying. Here, we have listed it among the coefficients in that expression.

__

The degree of a term is the sum of the degrees of the variables in the term. For terms with only one variable, it is the exponent of that variable. For terms such as the second expression, the degree is the sum of the exponents: 3+4 = 7. The degree of a polynomial with more than one term is the highest degree of all the terms.
