Answer:

difference is 12 units

Step-by-step explanation:

line shown has a y-intercept of -4

now find y-intercept of f(x) by first finding its slope:

(-2,0) and (2,-32)

m = (0+32)/(-2-2)

m = 32/-4

m = -8 (slope)

Now find the y-intercept (or 'b') from substituting into 'y=mx+b':

0 = (-2)(-8) + b

0 = 16 + b

-16 = b (y-intercept)

-16 - (-4) = -12

Answer:

-2

Step-by-step explanation:

6x + 10 = 1x

Subtract 6x from both sides.

10 = -5x

------------ Divide by -5

     -5

-2 = x

6x + 10 = 1x

Subtract 10 from both sides

6x + 10 (-10)= 1x (-10)

6x =1x - 10

Subtract 1x from both sides

6x (-x) = 1x (-x) - 10

5x = -10

Divide both sides by 5

5x (/5) = -10 (/5)

x = -2

Work Shown:

4.3*10^8 = 4.3 * 10^(3+5)

4.3*10^8 = 4.3 * 10^3*10^5

4.3*10^8 = 4.3*1000*10^5

4.3*10^8 = 4300*10^5

Priscilla has 4300*10^5 strands of hair while Diego has 8.7 * 10^5 strands. Subtract the values out front: 4300-8.7 = 4291.3

Then tack on the "*10^5" portion to get 4291.3*10^5

The difference in the number of strands is 4291.3*10^5

Convert this to scientific notation to get the final answer.

4291.3*10^5 = (4291.3)*10^5

4291.3*10^5 = (4.2913 * 1000)*10^5

4291.3*10^5 = 4.2913 * 1000*10^5

4291.3*10^5 = 4.2913 * 10^3*10^5

4291.3*10^5 = 4.2913 * 10^(3+5)

4291.3*10^5 = 4.2913 * 10^8

Note: The number 4.2913 * 10^8 expands out to 429,130,000 which is a little over 429 million.

Answer:

[tex]y=6x-4[/tex]

Step-by-step explanation:

First we have to know how to write a equation in Slope-Intercept Form!

Slope-Intercept Form: [tex]y=mx+b[/tex]

where y = y axis, m = slope, x = x intercept and b = y-intercept

Now start by solving the slope

To find the Slope, you must find two points

Two points will be: [tex](0,-4)[/tex] and [tex](1,2)[/tex]

Then use the Slope-Formula to identify the slope

[tex]m=slope[/tex]

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{2--4}{1-0}[/tex]

[tex]m=\frac{6}{1}[/tex]

[tex]m=6[/tex]

The Slope is 6

The y-intercept is already given by the point (0, -4)

Note: (this goes to this situation because the point has a 0 of x intercept)

The domain of the function y = 3[x] is (-∞, ∞), which means that the function is defined for all values of x.

A relation is a function if it has only One y-value for each x-value.

The function y = 3[x] is a piecewise function where [x] denotes the greatest integer function or the floor function, which returns the largest integer less than or equal to x.

The domain of the function is the set of all real numbers for which the function is defined.

As the greatest integer function is defined for all real numbers, the domain of the function y = 3[x] is also all real numbers.

Therefore, the domain of the function y = 3[x] is (-∞, ∞), which means that the function is defined for all values of x.

4x-10-32=

-40 -32= -72

Step-by-step explanation:

I think this is right sorry if I'm wrong

Answer:

We need to keep y on the left side only.

so we distribute the 4x to the right side.

that means:

4x - 4y = 8

-4x         -4x

-4y = 8 - 4x

Now we divide by -4 on both sides

y = 8 - 4x/-4

-2 + x is y

Answer: D

Step-by-step explanation:

The statement says that the angles GIH and QRS must be the same measurement. To show that on diagrams, we use markings : if angles have the same markings, then it means they have the same measurement.

That way, we just need to see which diagram has the right measurements.

First, the angles GIH and QRS are the angles we see named by the letter in the center : then GIH and QRS.

So it must be the angles with letters of I and R that have the same markings.

To find:

The quadratic polynomial whose zeroes are negatives of the zeroes of the given polynomial.

Solution:

We have,

[tex]x^2-x-12[/tex]

Equate the polynomial with 0 to find the zeroes.

[tex]x^2-x-12=0[/tex]

Splitting the middle term, we get

[tex]x^2-4x+3x-12=0[/tex]

[tex]x(x-4)+3(x-4)=0[/tex]

[tex](x+3)(x-4)=0[/tex]

[tex]x=-3,4[/tex]

The zeroes of the given polynomial are -3 and 4.

The zeroes of a quadratic polynomial are negatives of the zeroes of the given polynomial. So, the zeroes of the required polynomial are 3 and -4.

A quadratic polynomial is defined as:

[tex]x^2-(\text{Sum of zeroes})x+\text{Product of zeroes}[/tex]

[tex]x^2-(3+(-4))x+(3)(-4)[/tex]

[tex]x^2-(-1)x+(-12)[/tex]

[tex]x^2+x-12[/tex]

Therefore, the required polynomial is [tex]x^2+x-12[/tex].

A slope field for the given differential equation dy/dx = xy/2 at the 9 points indicated is shown below.

We know that a slope field represents the slope of a differential equation at certain vertical and horizontal intervals on the coordinate plane.

First we construct a table which contains the values of slope.

Consider given differential equation dy/dx = xy/2

where -1 ≤ x ≤ 1,

1 ≤ y ≤ 3

Let the slope be m

so, dy/dx = m

For x = -1, y = 1

m = (-1 × 1)/2

   = -1/2

For x = -1, y = 2

m = (-1 × 2)/2

   = -1

For x = -1, y = 3

m = (-1 × 3)/2

   = -3/2

For x = 0, y = 1

m = (0 × 1)/2

   = 0

For x = 0, y =2

m = (0 × 2)/2

   = 0

For x = 0, y = 3

m = (0 × 1)/2

   = 0

For x = 1, y = 1

m = (1 × 1)/2

   = 1/2

For x = 1, y = 2

m = (1 × 2)/2

   = 1

For x = 1, y = 3

m = (1 × 3)/2

   = 3/2

So, the table is:

x/y     1  2    3

-1     -1/2   -1      -3/2

0     0   0   0

1       1/2     1      3/2

The percentage of ounce Dariu has left of his port drink is 55%.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.

It is given that Dariu ha a 40-ounce port drink.

He drank 18-ounce port drink.

First calculate what percentage of port drink Dariu drank.

The equation is -

= (18/40) × 100

= 45%

So, Dariu drank 45% of the port Drink.

Now, subtract the percentage Dariu drank from the 100% (40 Ounce) drink Dariu had -

100 - 45 = 55

Substitution is the second strategy for solving a system of equations

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first equation be represented as A

Now , the value of A is

ax + by = c   be equation (1)

Let the second equation be represented as B

dx + ey = f   be equation (2)

On adding or subtracting both the equations , we can eliminate one of the variables from the system of equations

And , to calculate the other variable , substitute the value of the variable in either of the equations to solve the system of equations

So , we will get the value of the variable x and y

Hence , the system of equations can be solved by substitution

What is right-angled triangle?

Triangle that has one angle 90 degree is called right-angled. In case of a right triangle the square of the largest side length is equal of the sum of the square of the other two side length.

SA triangle has three side length 11-unit, 60 unit and 61 unit respectively.

The triangle is verified as a right-angled triangle by Pythagorean theorem.

And as the properties of a Pythagorean theorem the sum of the square of two side length is equal to the square of the largest side length.

if we say, one side length, a = 11 unit

             second side length, b = 60 unit

    the largest side length, c

now we will check,  

√(11²+60²) = c² =√3721 = 61

the value of c = 61 unit.

hence, the SA is right-angled triangle.

But go for it

The simplified value of x is 44 / 15 or 7 / 5 and value of y is -2

Simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

Given that, simply the following

a) 2(y-1)/3-3(y-2)/4=1

b) 3x=44/5=2x+6

1) 2(y-1) / 3 - 3(y-2) / 4 = 1

Multiplying by 12 to both sides,

8(y-1) - 9(y-2) = 12

8y-8 - 9y+18 = 12

-y + 10 = 12

y = -2

2) 3x = 44 / 5 = 2x+6

3x = 44 / 5

Multiplying by 5 to both sides,

15x = 44

x = 44 / 15

or,

44 / 5 = 2x + 6

Multiplying by 5 to both sides,

44 = 10x + 30

14 = 10x

x = 7 / 5

Hence, the simplified value of x is 44 / 15 or 7 / 5 and value of y is -2
