Explanation:

For now, let's call the y intercept b

We'll plug in x = 2 and y = 3 from the given point to find b

y = mx+b

y = (-1/2)x + b

3 = (-1/2)*2 + b

3 = -1 + b

3+1 = b

4 = b

b = 4

The y intercept is 4

The equation of the line is y = (-1/2)x + 4

f(3) is 0 for the given function

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given

f(x) = [tex]x^{3}+18x^{2} +104x+192 \ for x\leq -3[/tex]

f(x) = [tex]\frac{3x-9}{x^{3} -2x^{2} -5x+6} \ for -3\leq x\leq -3[/tex]

f(x) = [tex]\sqrt{x^{2} -9} \ for \ x > 3[/tex]

We need f(3)

f(x) = [tex]\frac{3x-9}{x^{3} -2x^{2} -5x+6} \ for -3\leq x\leq -3[/tex]

f(3) = [tex]\frac{3(3)-9}{3^{3} -2(3)^{2} -5(3)+6}[/tex]

f(3) = 0

Hence, f(3) is 0 for the given function.

Step-by-step explanation:

The slope-intercept form:

Use point (5, -3) and m = -4/5:

The line is:

Answer:

b = 1

Step-by-step explanation:

We know that

y = mx + b

-3 = -4/5 × 5 + b

-3 = -20/5 + b

-3 = -4 + b

-3 + 4 = b

1 = b

Answer:

a=24

b=7

now

24+(7-4)

24+3

Step-by-step explanation:

I think we need to area

Radius = Diameter/2

Radius = 8/2

Radius = 4 in

Area = πr²

Area = 22/7 × (4)²

Area = 22/7 × 16

Area = 50.28 in²

Step-by-step explanation:

According to question,

Diameter=8 inches

Therefore, Radius=D/2=8/2 inches=4 inches

Now,

To find perimeter,

2πr

2×22/7×4 inches

25.1428571 inches

To find area,

Answer:

  8/5 = 1.6

Step-by-step explanation:

It looks like the line crosses grid points (-4, -4) and (1, 4). This means the slope is ...

  m = (y2 -y1)/(x2 -x1)

  m = (4 -(-4))/(1 -(-4)) = 8/5 = 1.6

The slope of the line seems to be about 8/5, or 1.6.

this is because when 40 is broken down into two numbers (one divisible to get out of the square root, and one not) you get 25 + 15 under the square root. we know that the square root of 25 is 5, so we can put 5 outside the root and leave 15 inside.

Lorena tiene 20 canciones y su amigo tendria 40

Step-by-step explanation:

If the image move 90⁰ counterclockwise then it will become (-2, -1).

The value of the image of P under the rotation 90 degree counter about the origin is, (1, 2)

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

Point P is,

P = (2, - 1)

Now, We know that;

To rotate quadrilateral ABCD 90° counterclockwise about the origin we will use the rule (x, y) becomes (-y, x).

Hence, The value of the image of P under the rotation 90 degree counter about the origin is,

= (- (- 1), 2)

= (1, 2)

Thus, The value of the image of P under the rotation 90 degree counter about the origin is, (1, 2)

Answer:

25

Step-by-step explanation:

The angles b and 65 are complementary, meaning they sum to 90 degrees. You know this because those 2 angles and the right angle are sitting on a straight line. So, together they equal 180 and 180-90 is 90. Therefore, angle b+65 must equal 90. So, simply subtract 65 from 90 to get the answer, 25.

Answer:

24/100

Step-by-step explanation:

Simplest fractional form of 0.24 repeating will be 6/25.

Fractions: A number in p/q form where q must not be zero is termed as fractions.

Given, that number 0.24 is repeating in nature.

So, to convert 0.24 from decimal to fraction .

Remove the decimal by dividing the whole number by 100 as decimal is two places behind.

0.24 = [tex]\frac{24}{100}[/tex]

Simplify the fractional form,

GCF of 24 and 100 = 4

So divide 24 and 100 by 4,

Therefore the required fraction is ,
