Answer:
A) (5, 0)
Step-by-step explanation:
-2x+5y=-10
-2x+5(0)=-10
-2x+0=-10
-2x=-10
2x=10
x=10/2
x=5
(5, 0)
2) Draw a point five units to the right of zero.
3) Draw a point five units to the left of zero.
4) Draw a point one unit to the left of zero.
Answer:
Draw a point one unit to the left of zero.
Step-by-step explanation:
The equation of unknown w is given here and we have to solve it and then we have to check how to draw the point w on the number line.
Now, the equation is - 5w + 9 = 14
⇒ - 5w = 5
⇒ w = - 1
Now, we know that in a number line if we move right from zero then this is a positive direction and if we move left from zero then this direction is the negative direction.
Hence, to plot w = - 1, we must draw a point one unit to the left of zero. (Answer)
let that number be x
With geometric sequences, if you divide a term by the term before it you'll get the common ratio. That's how they are all constructed, and in this problem:
So -1/4 is our common ratio.
The common ratio of the geometric sequence −320, 80, −20, 5,… is -1/4 or -0.25.
It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have a geometric sequence:
−320, 80, −20, 5,…
As we know, the geometric sequence or progression follows a certain rule of arithmetic.
The common ratio = second term/first term or
First term = -320
Second term = 80
= 80/(-320)
= -1/4
The common ratio = -1/4 or -0.25
Thus, the common ratio of the geometric sequence −320, 80, −20, 5,… is -1/4 or -0.25.

The Michele's father is 23 inches taller than Michele.
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Michele is 52 inches tall.
And, Her father is 6 feet 3 inches tall.
Now,
Since, We know that;
⇒ 1 feet = 12 inches
Hence, The age of his father = 6 feet 3 inches
= 6×12 + 3
= 75 inches.
Hence, The length for Michele's father taller than Michele is,
⇒ 75 - 52 inches
⇒ 23 inches.

The student is wrong, the correct expression is 9(n + 13).
Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.
Given the phrase “9 times the sum of a number and 13”
Let, n = the number
Therefore,
The sum of a number and 13 is:
n + 13
9 times the sum of a number and 13” can be written as,
9(n + 13)
Hence, the student is wrong.
