Answer: first option 3, - 7

Justification:

2) Each monomial is a term.

The monomials are each  combination of numbers and letters (coefficient, letters and exponents) separated of other monomials (terms) with a + or - operator.

3) Therefore, there are 3 terms which are:

-5x, and
-7.

The polynomials with 3 terms are called monomials.

4) The monomial (term) withoud letter is the constant. In this case that is  -7.

Slove system of equations y=2x-3 y=x^2-2x-8
Fiesta28 [93]

Answer:

2 solutions:

x=5 and y=7

x=-1 and y=-5

Step-by-step explanation:

y=2x-3

y=x^2-2x-8

y=y   so:

2x-3=x^2-2x-8

simplifying to:

x^2-4x-5=0

factoring to:

(x-5)(x+1)=0

x=5 or x=-1

if x=5 then y=2(5)-3=7

if x=-1 then y=2(-1)-3=-5

Find x. (Use pic for more info)
V125BC [204]

Answer:

x=75

Step-by-step explanation:

Hey There!

If you didn't know the exterior angle of a triangle is equal to the sum of the opposite interior angles of a triangle

So essentially what I'm saying is that

2x-5=70+x

step 1 add 5 to each side

-5+5 cancels out

70+5=75

now we have

2x=70+x

step 2 subtract x from each side

x-x cancels out

2x-x=x

we're left with

x=75

A country clerk has given amount of money to budget for cultural events
Neko [114]

Answer:

A. the total amount of the budget given to the country

Step-by-step explanation:

In order to know the answer, you have to check what the<em> y-axis</em> represents. In the graph above, it represents the "Budget Remaining," which is expressed in <em>thousands of dollars. </em>On the other hand, the<em> x-axis</em> represents the "Time," which is expressed in<em> months</em>.

Point (0,18) shows the total amount of the budget for the Cultural Events in the country. It starts at 18,000 dollars and decreases as months pass by. This is shown by the graph's <em>"negative slope."</em> This means that<u> as the number of months increases, the amount of money decreases.</u>
