What is the simplified form of this expression (8x^2-3x+1/3) - (2x^2-8x+3/5)
Answers
Answer:=6x2+5x + −4/15
Step-by-step explanation:Let's simplify step-by-step.
8x2−3x+13−(2x2−8x+3/5)
Distribute the Negative Sign:
=8x2−3x+13+−1(2x2−8x+3/5)
=8x2+−3x+13+−1(2x2)+−1(−8x)+−1(3/5)
=8x2+−3x+13+−2x2+8x+−3/5
Combine Like Terms:
=8x2+−3x+1/3+−2x2+8x+−3/5
=(8x2+−2x2)+(−3x+8x)+(1/3+−3/5)
=6x2+5x+−4/15

find an equation of the line passing through the point (5 4) and parallel to the line whose equation is y= 2x-6
Answers
Answer:
[tex]y = 2x - 6[/tex]
Step-by-step explanation:
Given
Equation: [tex]y = 2x - 6[/tex]
Required
Determine the equation of Point: (5,4)
First, we need to determine the slope of [tex]y = 2x - 6[/tex]
The general form of an equation is [tex]y = mx + b[/tex]
Where m represents the slope;
Hence; [tex]m =2[/tex]
Since the equation and the point are parallel. then they have the same slope (m).
[tex]m = 2[/tex]
Next, is to determine the equation of the point, using the following formula:
[tex]m = \frac{y - y_1}{x - x_1}[/tex]
Where
[tex](x_1,y_1) = (5,4)[/tex]
So, the equation becomes
[tex]2 = \frac{y - 4}{x - 5}[/tex]
Cross Multiply
[tex]y - 4 = 2(x - 5)[/tex]
Open Bracket
[tex]y - 4 = 2x - 10[/tex]
Make y the subject of formula
[tex]y = 2x - 10 + 4[/tex]
[tex]y = 2x - 6[/tex]
Hence, the equation is [tex]y = 2x - 6[/tex]

What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
What is a scale image?Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions on the actual figure or object
A rotation of 90° counter-clockwise about the origin is defined as the x-coordinate and y-coordinate change places, and the line y = x is the coordinates (-x , y).
To determine the image of the point (-9, -8) after a rotation of 90° counterclockwise about the origin
Suppose, the coordinates are (a,b)
A point (a,b) reflected across the line y = -x will become (-a,b).
Let a = -9 and b = -8
Substitute the values of a and b,
So the coordinates of image (9, -8)
Hence, the coordinates of the image (9, -8) after a rotation of 90° counter-clockwise about the origin.

Part ll: Explain the difference between a savings account earning simple interest and a savings account earning compound interest.
Part Ill: Which type of savings account would you open and why?
Answers
Answer:
part 1: You start with an annual "simple interest rate," which is the percentage of the principal balance your money earns each year. ... Add the daily interest earned to the balance.
part 2: Simple interest is based on the principal amount of a loan or deposit. In contrast, compound interest is based on the principal amount and the interest that accumulates on it in every period.
part 3: a compound interest account and here's why. When it comes to investing, compound interest is better since it allows funds to grow at a faster rate than they would in an account with a simple interest rate

Steve weighs 18 more pounds than Ryan. If their weight totals 144 pounds, how much does Ryan weigh?
Answers
Answer:
A) Steve = Ryan +18
B) Steve + Ryan = 144
A) Steve -Ryan = 18 then adding B
B) Steve + Ryan = 162
2 Steve = 162
Steve weighs 81 pounds
Ryan weighs (81 -18) pounds 63 pounds
Step-by-step explanation:
X + 18 = Steve’s weight
144 = total weight for both
X + X + 18 = 144 ( equation)
2X = 144 -18 (group your equation)
2X/2 = 126/2 (divide both sides by 2)
X = 63 ( Ryan’s age)
X + 18 = 81 ( Steve’s age)
