Answer:

(0, -1)

Step-by-step explanation:

y-14=6(x-2.5)

Distributive property:

y-14 = 6 * x - 6*2.5

y-14= 6x-15

Add 14 on each side:

y-14+14=6x-15+14

Simplify:

y=6x-1

In the form y=mx+b (slope-intercept form, as shown above), the y-intercept is (0, b). b is -1.

Answer:

The y intercept is -1

Step-by-step explanation:

y-14=6(x-2.5)

We need to get the equation in the form y = mx+b where b is the y intercept

Distribut the 6

y-14 = 6x -15

Add 14 to each side

y-14+14 = 6x-15+14

y = 6x-1

The y - intercept is -1

jekas [21]

The cost of one sundae is s and cost of one cone is c.

Mark buys 4 sundae and 3 cones for a total of $26. Cost of 4 sundae will be 4s, cost of 3 cones will be 3c. So we can set up the equation for Mark as:

$4s+3c=26$

Brian buys 5 sundae and 2 cones for a total of $29. Cost of 5 sundae will be 5s, cost of 2 cones will be 2c. So we can set up the equation for Brian as:

$5s+2c=29$

Using these two equations, the cost of one sundae and one cone can be calculated.

gizmo_the_mogwai [7]

Answer:

Option d)

$H_{0}: p = 0.75\\H_A: p \neq 0.75$

Step-by-step explanation:

We are given the following in the question:

Three of four people believed that the state of the economy was the country's most significant concern.

They would like to test the new data against this prior belief.

The null hypothesis will state that the three of four people believed that the state of the economy was the country's most significant concern.

The alternate hypothesis will state that this is not true. It states that people believed that the state of the economy was the country's most significant concern is not the same.

$p =\dfrac{3}{4} = 0.75$

We design the null and the alternate hypothesis

$H_{0}: p = 0.75\\H_A: p \neq 0.75$

Which function shows a fabric with a price of $1.25 per square yard? A table showing Price of Fleece with five columns and two r

morpeh [17]

Answer:

Answer D is correct

Step-by-step explanation:

1: (1, 1.25) (2, 2)

So you have your first problem, your first number is x1 while your next number in the first set of parenthesis is y1. Your next set of parenthesis will be x2 and y2 like this:

x1 y1 x2 y2

(1, 1.25) (2, 2)

Then you set up a equation like this!

x2-x1

-------Divided

y2-y1

so we now plug in the numbers and get this

2-1.25 = 0.75

--------- ---- or 0.75 BUT not 1.25 like we need!

2-1 = 1
