Answer:

a) [tex]y=\frac{23}{6} x-156[/tex]

b) [tex]\frac{268}{3}[/tex]

Step-by-step explanation:

Formulas for linear equations:

Slope-intercept: [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept

Point-slope: [tex]y-y_1=m(x-x_1)[/tex], where (x₁, y₁) is a point on the function and m is the slope.

a) We are given two points. If you're given two points (x₁, y₁) and (x₂, y₂), the slope m is given by the formula:

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

Let's mark the temperature on the x-axis, and the number of chirps per minute on the y-axis. So, we have the following points: (60, 74), and (72, 120). Calculating the slope m between these two points:

[tex]m=\frac{120-74}{72-60}[/tex]

[tex]m=\frac{23}{6}[/tex]

Since we have the x and y coordinates of a point on the function, we can write an equation in point-slope form, which will help us to find the y-intercept. We need the y-intercept in order to write the slope intercept form of the equation. We will use the point (60, 74) here, although you can also use (72, 120) if you want.

Point-slope form equation of the linear function:

[tex]y-74=\frac{23}{6} (x-60)[/tex]

Now that we have the point-slope equation of the function, we can find the y-intercept. The y-intercept is the point on the function where the graph crosses the y-axis (when the x-value is 0). So, we plug in 0 for x into the equation and solve for y:

[tex]y-74=\frac{23}{6} (0-60)[/tex]

[tex]y=-230+74[/tex]

[tex]y=-156[/tex]

Now that we have the y-intercept value of the function, we can write an equation in slope-intercept form:

[tex]y=\frac{23}{6} x-156[/tex]

b) Since we marked the temperature on the x-axis, we can just plug in the number 64 as the x-value into the equation we have. y will be the number of chirps per minute when the temperature is 64º.

[tex]y=(\frac{23}{6} *64)-156[/tex]

[tex]y=\frac{736}{3} - \frac{468}{3}[/tex]

[tex]y=\frac{268}{3}[/tex]

Answer:

Hebrew National since the cost is only 0.73

Step-by-step explanation:

First we need to identify the cost of each hotdog for each brand. I'll go by in order.

Ball Park:

We know that it cost $6.95 and it's 8 dogs for each one. Meaning all we have to do is divide the price by the amount of hot dogs.

"Price/Hotdogs per package"

In order

6.95/8=0.86875 or 0.87

8.20/10=0.82

7.35/8=0.91875 or 0.92

17.50/24=0.7291666 or 0.73

Since we're dealing with currency we would most likely round it by the nearest hundredth so the true answer would be $0.87.

Use this formula that I made for this question for any other questions.

Answer:

D because that is the smallest angle on there baby doll

Step-by-step explanation:

have a nice day sugar bear

Answer:

D

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

4x + 8x - 9 + 57 = 180, that is

12x + 48 = 180 ( subtract 48 from both sides )

12x = 132 ( divide both sides by 12 )

x = 11

Thus

∠ A = 4x = 4 × 11 = 44° → D

answer for -2x+3y=6: x=3/2y-3

pls give brainliest

Answer:

There are infinitely many solutions.

Step-by-step explanation:

There are infinitely many solutions because if you solve the equations, you will find that both of the equations are actually the same, so there is infinitely many solutions.

Showing that both equations are equal:  y=2/3x+2       -2x+3y=6

y=2/3x+2  Multiply by 3 on both sides

3y=2x+6 Rearrange (-2x on both sides)

3y-2x=6 More rearrangement

-2x+3y=6 Now, if you look back at the second equation, you will see that they are both the same.

Answer: [tex]x = -5[/tex]

Step-by-step explanation:

If a product of 15 and an unknown number equals -75 the equation should look like this:

[tex]15x = -75[/tex]

Now to solve for x:

1. [tex]\frac{15x}{15} = \frac{-75}{15}[/tex]

2. [tex]x = -5[/tex]

The solution for x is -5.

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. LHS = RHS is a common mathematical formula.

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. Equal treatment should be given to each party.

Given:

The product of 15 and a number X is -75.

So, the expression is

15x = -75

Now, divide 15 on both side

15x/15= -75/15

x= -5

Hence, the value of x is -5.
