y=mx+b
y=-2/12x-8
Simplify:
y=-1/6x-8
Slope intercept is really easy. m is the slope. All you have to do is find 2 points and use rise/run. Rise is how many up or downs (numerator). Run is left or right (denominator). We are given 2 points in the graph. So I counted, 2 down, 12 left. So 2/12. Now remember if the line is going down from left to right, it’s a negative slope. So -2/12. To find the y intercept, just find where the line meets at the y intercept, here it’s -8. So y=-2/12x-8. y=-1/6x-8

Answer:

Step-by-step explanation:

For a lot of these summation problems it is worthwhile to learn to use a calculator or spreadsheet to do the arithmetic. Here, the ends of the intervals are 1 unit apart, so we only need to evaluate the function for integer values of x.

Almost any of these numerical integration methods involve some sort of weighted sum. For trapezoidal integration, the weights of all of the middle function values are 1. The weights of the first and last function values are 1/2. The weighted sum is multiplied by the interval width, which is 1 for this problem.

The area by trapezoidal integration is about 1.649 square units.

In the attached, we have shown the calculation both by computing the area of each trapezoid (f1 does that), and by creating the weighted sum of function values.

what does b equal?
-15 b - 25 = -2

Answers

Answer:

b = - [tex]\frac{23}{15}[/tex]

Step-by-step explanation:

- 15b - 25 = - 2

- 15b - 25 + 25 = - 2 + 25

- 15b = 23

- 15b ÷ - 15 = 23 ÷ - 15

b = - [tex]\frac{23}{15}[/tex]

9. Use the graph of each polynomial function to find the factored form of the related polynomial.
Assume the polynomial has no constant factor.
A.
What are the zeros of this function? (2 points)
what is the factorization of the polynomial

Answers

Answer:

A) the zeros are; x = -2 and x = 4

B) y = (x + 2)(x - 4)

Step-by-step explanation:

A) The zeros are the values of x where the graph curve crosses the x-axis.

Looking at the graph, the curve crosses the x-axis at x = -2 and x = 4

Thus, the zeros are; x = -2 and x = 4

B) Factorization of the polynomial means that we transform the zeros into the polynomial.

Thus, we have; y = (x + 2)(x - 4)

So when y is zero, x = - 2 or 4 as earlier derived.

The frequency, or pitch, of a musical note varies inversely with the wavelength. The speed of sound, 340.2 meters per second, is the constant of variation.

An “A” note in octave 5, has a frequency of 880 Hertz. What is the wavelength of the sound made by the tuner in meters?

Answers

Answer:

The wave length = 0.387 meters

Step-by-step explanation:

Remark

An inverse relationship is one of the variables is in the denominator of a fraction and the other is given on the other side of the equal sign. It sounds more complicated than it is. Here's that long sentence broken down to 3 letters.

f = k/w

Formula

f = k/w

f is the frequency

k is the speed of sound

w is the wavelength

Givens

f = 880 Hz

k = 340.2 m/s

w = ?

Solution

f = k/w

880 = 340.2/ w Multiply both sides by w

880*w = w* 340.2 /w

880*w = 340.2 Divide by 880

w = 340.2/880

w = 0.387 m

What is the measure of arc DGF

Answers

Answer:

DGF=226

Step-by-step explanation:

Angle 113 is a inscribed angle since two it is on the exterior of the circle. We can find the central angle by multiply 2 by 113.

113×2=226

Since the central angle measure 226, that means the arc DGF measures 226 degrees.

DGF=113

Charla works at a clothing store. Her pay is calculated using the formula p = 550 +0.15t, where p is her total pay, d is the number of days
she worked, and is the amount of her total sales.
What were her total sales if her pay was $785 and she worked 5 days?

Answers

The total sales if her pay was $785, and she worked 5 days will be $1,000.

The correct equation is p = 55d + 0.15t.

What is simplification?

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

Charla works at a clothing store.

Her pay is calculated using the formula

p = 55d + 0.15t

where p is her total pay, d is the number of days she worked, and t is the amount of her total sales.

Then the total sales if her pay was $785, and she worked 5 days will be

785 = 55 × 5 + 0.15 t

0.15t = 510

t = $1,000

For a party Gary buys cheese pizzas for $5 and pepperoni pizzas for $8 each. His bill comes to $75. Let x represent the number of cheese pizzas and y represent the number of pepperoni pizzas. Write an equation to represent the situation.

Answers

Answer:

The answer is the second answer from the image. Which is 5x-8y=$75

Step-by-step explanation:

It is that answer because it costs $5 for one cheese pizza and $8 for a pepperoni pizza, so the answer is 5x-8y=75

still confused?

Its that answer because the first one and the third one are the same, just both equations like in different ways like example 10+2 is 12 right? And 2 + 10 is still 12 so that means the second answer from the image is the answer.

Hope that helps.

Answer:

the answer for this question is the first choice.

Step-by-step explanation:

first, let's figure what number represents what. we know that cheese pizzas gary bought costed him $5 and pepperoni pizzas costed him $8. since x represents cheese pizzas and y represents pepperoni pizzas, 5x and 8y should be correct. this is also said in the problem which gives the correct addends. for the operation, it tells us the bill COMES to $75. since the pizzas are COMING to $75 in total, we know that this is addition.
