Your teacher is giving a test that has 5 more four-point questions than six-point questions.
The test is worth 120 points. Which system represents this information?
Answers
Answer:
x-y=5
4x+6y=120
Step-by-step explanation:
let x = # of 4-point questions
ley y = # of 6-point questions
# of 4-point questions is 5 more than # of 6-point questions
x=y+5 or x-y=5
now there's the matter of the points. Since each x is worth 4 points and each y is worth 6 points, they total number of points have to add up to 120, therefore:
4x+6y=120
The System of Equation is
x-y=5
4x+6y=120
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let x be number of 4-point questions.
ley y be number of 6-point questions.
as, the 4-point questions is 5 more than 6-point questions
So, x=y+5
or x-y=5.................(1)
Since each x is worth 4 points and each y is worth 6 points, they total number of points is 120.
So, 4x+6y=120....................(2)

I HOPE MY ANSWER HELPS U;)Find the number of terms and the degree of this polynomial.
Answers
Answer:
Number of terms = 3
Degree = 6
Step-by-step explanation:
A polynomial is a mathematical expression that gives the detailed combination of variables with their coefficients, their positive exponential, and other variables using the operations of subtraction, addition, and multiplication
The number of terms in a polynomial is the number of different powers of added or subtracted in the expression
Therefore, the number of terms in the expression -3·s⁶ + 2·s⁴ + 3·s³ is 3 terms
Number of terms = 3
The degree of a polynomial is given by the highest power of the variables in the polynomial. Therefore, the degree of the given polynomial is 6
Degree = 6

Notice how y=4x%2B2 is in slope-intercept form y=mx%2Bb where m is the slope and b is the y-intercept.
So this shows us that the slope is m=4 and the y-intercept is b=2 which is the point (0,2)
You can always plot an equation like this to find intercepts
and slope. Each point requires an x and a y. My
way is to make x+=+0 and find y,
then I make y+=+0 and find x
y+=+4x+%2B+2
y+=+4%2A0+%2B+2 solve for y
y+=+2
the point is (0,2)
then,
0+=+4x+%2B+2 solve for x
subtract 2 from both sides
4x+=+-2
x+=+-%281%2F2%29
the point is (-%281%2F2%29,0)
Once you have any two points, you can draw the line by connecting them
When the equation is in the form
y+=+mx+%2B+b
m = slope
b = y-intercept
So, your equation y+=+4x+%2B+2
m+=+4 (slope)
b+=+2 (y-intercept)

Solve for the first variable in one of the equations, then substitute the result into the other equation.

At a car dealership, salespeople earn a 5% commission on the first $10,000 of every sale, plus a 3% commission on any amount over $10,000. A salesperson sold a car for $12,300. What was the total commission on the sale? help me due today
Answers
Answer:
The total comission on the sale was $375.
Step-by-step explanation:
Since the salesperson sold the car for $12,300, the total comission on the sale would be equal to the 5% of $10,000 plus the 3% of the remaining amount which would be:
Total comission=(10,000*5%)+(12,500-10000)*(3%)
Total comission=500+(2,500*3%)
Total comission=300+75
Total comission=375
According to this, the answer is that the total comission on the sale was $375.
