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

Answer: 1

Answer:

5/12 cake was left for everyone else

Step-by-step explanation:

1/4 + 1/3

convert so denominators are equal

1/4 x 3 = 3/12

1/3 x 4 = 4/12

3/12+4/12=7/12

12/1-7/12= 5/12

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]

Step-by-step explanation:

Inequality and equality is that inequality is an unfair, not equal state while equality is (uncountable) the fact of being equal.

Step-by-step explanation:

Hey there!!

Given, The ratio is: 5:7

Let x be a common factor.

Now,

5x+7x = 60

12x = 60

[tex]x = \frac{60}{12} [/tex]

Therefore, x= 5.

5x = 5×5 = 25.

7x= 7×5=35.

Step-by-step explanation:

The coordinates of the image (9, -8) after a rotation of 90° counter-clockwise about the origin.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

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.

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

Answer:

0.89

Step-by-step explanation:
it was right

The value of the trigonometric function sin 63° is 0.89. So option C is correct.

Trigonometry is a branch of mathematics, which deals with the study of right angle triangles. Trigonometry is concerned with specified functions of angles and their applications to calculations.

There are 6 commonly used functions in trigonometry with their name and abbreviations-

sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), cosecant (cosec)

Given that,

the trigonometric function is sin63°

the value of sin63° = ?

One of the way to calculate the value of sin63° is by using calculator

And from the calculator its value can be estimated as 0.89100

After round figure up-to two  digit

we can write the value sin63° is 0.89.

Hence, the value of the function from the calculator is comes out as 0.89.

Each friend is running a half mile.

They are running 1/2 mile.

The operations of addition, subtraction, multiplication, division, exponentiation, and modulus are carried out by the arithmetic operators.

They cover the study of numbers, including the order of operations, which are useful in algebra, data handling, and geometry, among other areas of mathematics.

Given Hotah and his 3 friends are each running 1/4 of a 2-mile relay race

total distance covered by them out of 2 miles is

2 x 1/4 = 1/2 miles

Therefore each person runs at 1/2 a mile.
