Use the equation below to answer the question.
Ratling [72]

Answer:

The equivalent equation is correctly matched with a key feature of the graph is

y = 3(x + 2) highlights that the x-intercept is at -2.

Step-by-step explanation:

Given:

y=3x+6

Solution:

The Given Equation is in Slope - Point Form i.e

y=mx+c

Where,

m=slope\\\\c=y-intercept

On Comparing the given equation with above we get

slope=m=3\\\\y-intercept =6

Now we Know that

Intercepts:

The line which intersect on x-axis and y-axis are called intercepts.

There are two intercepts:

y-intercept: The line which intersect at y-axis. So when the line intersect at y-axis X coordinate is zero.

x-intercept: The line which intersect at x-axis. So when the line intersect at x-axis Y coordinate is zero.

For x-intercept

Put y = 0 in

y=3(x+2)

0=3x+6\\\\3x=-6\\\\\therefore x=\dfrac{-6}{3}=-2

∴ x-intercept of

y=3x+6

x-intercept = -2

The equivalent equation is correctly matched with a key feature of the graph is

y = 3(x + 2) highlights that the x-intercept is at -2.

In a bag of 100 marbles comprised of many colors, 25 are blue. suppose marbles are selected at random.
satela [25.4K]

Solution: The number of ways we can arrange 3 blue marbles if a set of 5 marbles is selected is:

\binom{5}{3}=\frac{5!}{(5-3)!3!}

                          =\frac{120}{2 \times 6}

                          =\frac{120}{12}=10

Therefore, there are 10 ways we could arrange 3 blue marbles.

bazaltina [42]

Answer:

f(x) = 7x + 5.

Step-by-step explanation:

The equation that represents the function can be written in the slope-intercept form, f(x) = mx + b.

To create an equation, we need to find the slope (m) and the y-intercept (b) of the function.

First, calculate the slope of the function using two points, (1, 12) and (2, 19).

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{19 - 12}{2 - 1} = \frac{7}{1} = 7

Next, find b by substituting x = 1, f(x) = 12, and m = 7 into f(x) = mx + b.

12 = (7)(1) + b

12 = 7 + b

Subtract 7 from each side

12 - 7 = b

5 = b

b = 5

Substitute m = 7 and b = 5 into f(x) = mx + b.

✅Thus, the equation that represents the function would be:

f(x) = 7x + 5.
