Answer:

Step-by-step explanation:

$\left\{\begin{array}{ccc}y=3x+2&(1)\\y=5x&(2)\end{array}\right\\\\\text{substitute (2) to (1):}\\\\5x=3x+2\qquad\text{subtract 3x from both sides}\\2x=2\qquad\text{divide both sides by 2}\\x=1\\\\\text{Put the value of x to (2):}\\\\y=5(1)=5$

Which of these could be the value of x in the triangle below

Yuliya22 [10]

The value of x is drawn from the other angles
(There is no triangle for us to look at) so here is a example

Triangle abc has the values as a=23+x° b=x c=69°

All triangles have a combined value of 180°
Now you would have to add the values together and set it equal to 180

23+x+x+69=180
Combine like terms
(69+23)+(x+x) =180
92+x^2=180
Then subtract 92 from 180
Then you have x^2=88
Then you square root the x^2 to make it just x
Then square root 88 because whatever you did to one side has to be done on the other side
X≈ 9.4

Answer: (A) The rate of change in the price of a bushel of corn in the current year is $7.

(B) The price of a bushel of corn in the current year is $2 more than the price of a bushel of corn in the previous year.

Step-by-step explanation:

The graph for the prices of different numbers of bushels of corn at a store in the current year is shown below.

Part A:

The rate of change in the price of a bushel of corn in the current year based upon the number of bushels is known as the slope of the line.

The formula to compute the slope is:

Consider the ordered pairs: (4, 28) and (10, 70)

Compute the slope of the line as follows:

Thus, the rate of change in the price of a bushel of corn in the current year is $7.

Part B:

The data for the price of bushels in the previous year is as follows:

Number of Bushels Price

2 10

4 20

6 30

8 40

Compute the rate of change in the price of a bushel of corn in the previous year based upon the number of bushels as follows:

Consider the ordered pairs: (2, 10) and (6, 30)

The rate of change in the price of a bushel of corn in the previous year is $5.

Thus, the price of a bushel of corn in the current year is $2 more than the price of a bushel of corn in the previous year.

Help me with this im confused

Answer:

y=6x

Step-by-step explanation:

1. find the slope m. Pick two points on the line, such as (0,0) and (1,6). Plug those points into the slope formula.

m=change in y/change in x

m=6-0/1-0 Plug in (0,0)(1,6)

m=6/1 simplify

m=6

The slope is 6

2. Find the y-intercept. Since the line crosses the y-axis at 0, the y-intercept is 0.

3. Use the slope m=6 and the y-intercept b=0 to write the equation in slope-intercept form.

y=mx+b

y=6x+0 Plug in m=6 and b=0

y=6x

The equation of a circle is (x-2) squared + (y-6) squared =64. What is the center and radius of the circle.

evablogger [386]

Answer:

The center (2,6) and the radius is 8

Step-by-step explanation:

The equation of a circle is (x-h)^2 + (y-k)^2 =r^2

where (h,k) is the center of the circle and r is the radius

We have

(x-2)^2 + (y-6)^2 =64

(x-2)^2 + (y-6)^2 =8^2

The center (2,6) and the radius is 8
