1 Evaluate the expression 2a + b - 3 when a=5 and b=2. Please click on "show your work" to set up the problem and show your work. Then, enter your answer in the box to the right. You must complete both of these steps. Evaluate the expression 2a + b - 3 when a=5 and b=2. Set up the expression and show your work.
Answer:
11
or
2(5)+2-3
Step-by-step explanation:
if a = 5 and b=2,
you add it into the expression.
2a + b -3 --> 2(5) + 2 - 3
all you have to do is replace the letters with the (given) numbers.
then, solve.
2(5) = 10
2-3= 1
10+1 =11
the answer is 11.

The Value for the expression 2a + b -3 is 9.
What is Expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
Expression: 2a+ b -3
Now, for a=5 and b=2 thee expression gives
= 2a + b -3
= 2(5) + 2 -3
= 10 +2 - 3
= 12 - 3
= 9
Hence, the Expression valued 9.

Heeeeeeeellllllpppppppppp!
Answer:
D
Step-by-step explanation:
15 - 2.5x = 40 ( isolate the term in x by subtracting 15 from both sides )
- 2.5x = 40 - 15 = 25 ← Step 1
divide both sides by - 2.5
x = 25 ÷ - 2.5 ← Step 2
x = - 10

Step-by-step explanation:
In the trapezoid below, x = [? ]
if this trapezoid is to scale, then the scale factor between the shortest and longest side is 1.5
so, that means that 1.5(2x+6) = 4x+2
so, your equation becomes 3x+9 = 4x+2
if you subtract 2 from each side, you get 3x+7 = 4x
meaning that x = 7

Jack has a points card for a movie theater. He receives 55 rewards points just for signing up. He earns 12.5 points for each visit to the movie theater. He needs at least 205 points for a free movie ticket. Write and solve an inequality which can be used to determine vv, the number of visits Jack can make to earn his first free movie ticket.
Answer: See explanation
Step-by-step explanation:
Since Jack receives 55 rewards points just for signing up and earns 12.5 points for each visit to the movie theater and needs at least 205 points for a free movie ticket.
The inequality which can be used to determine v, the number of visits Jack can make to earn his first free movie ticket will be:
55 + 12.5v ≥ 205
12.5v ≥ 205 - 55
12.5v ≥ 150
v ≥ 150/12.5
v ≥ 12
The number of visits that Jack can make to earn his first free movie ticket will be at least 12 visits

Step-by-step explanation:
12.5/1.25=10
This means that to get from Figure B to A, you would need to divide by 1.25
So to get from Figure A to B, you would have to multiply by 1.25
16*1.25=20
How does knowing one linear factor of a polynomial help find the other factors?
Answer:
How does knowing one linear factor of a polynomial help find the other factors?
Step-by-step explanation:
f(x)=(x−3)(x−1)(x+2)(x+6)
f(x)=(x−2)(x−2)(x+3)(x+5)
f(x)=(x−5)(x−3)(x+2)(x+2)
f(x)=(x−8)(x−1)(x+3)(x+5)
f(x)=(x−2)(x−1)(x+4)(x+4)
Correct answer:
f(x)=(x−2)(x−2)(x+3)(x+5)
Explanation:
We begin by attempting to find any rational roots using the Rational Root Theorem, which states that the possible rational roots are the positive or negative versions of the possible fractional combinations formed by placing a factor of the constant term in the numerator and a factor of the leading coefficient in the denominator.
That was a lot of wordage in one sentence, so let's break that down. We begin with our polynomial.
f(x)=x4+4x3−13x2−28x+60
The constant term is the term without a variable (just a plain number). In our case the constant is 60. What are the possible factors of 60?
1,2,3,4,5,6,10,12,15,20,30,60
The leading coefficient is the number in front of the largest power of the variable. When the terms are listed in descending order (highest to lowest power), the leading coefficient is always the first number. In our case the leading coefficient is hard to spot. Since there is no number in front of x4, the coefficient is 1 by default.
This is nice because the only factor of 1 is well ... 1.
We then create all the possible fractions with a factor of the constant in the numerator and a factor of the leading coefficient in the denominator. This actually isn't as bad as it could be since our only possible denominator is 1. Any fraction with a denominator of 1 is just the numerator. Therfore, our possible "fractions" are simply
1,2,3,4,5,6,10,12,15,20,30,60
However, we must consider the positive or negative versions of these, so our final list of possible rational roots is
±1,±2,±3,±4,±5,±6,±10±,1±2,±15,±20,±30,±60
Unfortunately, this is where the process (at least without the assitance of a graphing calculator) becomes less fun. Using synthetic division, we must simply try each possible root until we have success. There's really no consistent rule to tell us where to start. Generally starting with the smaller whole numbers is best because the synthetic division is easier. Therefore, we could begin with 1 then proceed to −1,2,−2, etc.
For the sake of keeping this explanation as short as possible, I am going to skip straight to 2, where we will first find success.
Therefore, 2 is a root. However, it is always important to check to see if a root is in fact a double root (it works twice). Therefore, let's try it one more time.
2 does in fact work twice and is thus a double root. Since we only have three terms remainng, we can convert from synthetic back to an algebraic expression.
f(x)=x2+8x+15
We can then factor.
f(x)=(x+3)(x+5)
Writing our root of 2 as an algebraic expression gives (x−2). Since we have double root, we need two of these. Therfore, our final factored expression is.
f(x)=(x−2)(x−2)(x+3)(x+5)

In this question, we have been given a situation where your Language Arts teacher expects you to read an entire book over the 3 day weekend.
On Tuesday you are on page 60 and are 1/5 of the way done.
We have been given a fraction 1/5.
We need to find the number of pages in the book.
Let 'n' be the number of pages in the book.
60 = 1/5 × n
n = 5 × 60
n = 300
Therefore, there are 600 pages in the book.
