Given:

The graph of linear function.

To find:

The slope intercept form of the linear equation from the given graph.

Solution:

The slope intercept form of a linear function is:

y=mx+b

From the given graph it is clear that the graph passes through the points (1,300) and (4,800).

The equation of line is

y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)

y-300=\dfrac{800-300}{4-1}(x-1)

y-300=\dfrac{500}{3}(x-1)

y-300=\dfrac{500}{3}x-\dfrac{500}{3}

Adding 300 on both sides, we get

y=\dfrac{500}{3}x-\dfrac{500}{3}+300

y=\dfrac{500}{3}x+\dfrac{900-500}{3}

y=\dfrac{500}{3}x+\dfrac{400}{3}

Therefore, the required equation is y=\dfrac{500}{3}x+\dfrac{400}{3}.

A glitter glue recipe takes a mixture of 1 5 cup of glitter to 2 5 cup of glue. For A, how many cups of glitter are used for 1 c
tatiyna

0.6 cup of gliter is used for 1 cup of glue and 1.6 cup of gliter glue is made with 1 cup of glue.

Part A

Given that,

15 cup of gliter is for 25 cup of glue ,

Therefore, "X" cup of gliter is for 1 cup of glue

X = (1*15)/25

X= 0.6 cup of gliter

Part B,

Given that,

From part A 0.6 cup of gliter is for 1 cup of glue

Thus, 1 cup of glue and 0.6 cup of gliter when mixed will form "Y" cup of gliter glue

Now, Y= 0.6 cup of gliter + 1 cup of glue

Y= 1.6 cup of gliter glue

which approximates to 2 cup of gliter glue.

What is the vertex form of y=-1/2x^2 -2x -3?
STALIN [3.7K]

Answer:

y = − 1 2 ⋅ ( x + 2 ) 2 − 1

Step-by-step explanation:

To convert a quadratic from y = ax2 + bx + c form to vertex form, y = a(x - h)2+ k, you use the process of completing the square. Let's see an example. Convert y = 2x2 - 4x + 5 into vertex form, and state the vertex. Equation in y = ax2 + bx + c form.
