Based on the graphs of the equations y = x + 7 and y = x2 – 3x + 7, the solutions are located at points:
Triss [41]

The correct option is A. (4, 11) and (0, 7).

The solution of the equations y = x + 7 and y = x² – 3x + 7, the solutions are located at points: (4, 11) and (0, 7).

<h3>What is the system of linear equation?</h3>

Estimate the y-intercept, slope, and express the equation in the form of the y-intercept (y = mx + b) to find the graphed equation. The slope is the difference between the y- and x-axis values.

A graph equation is an equation in graph theory where the unknown is a graph. Isomorphic ideas are one of the key issues in graph theory.

The equations are; y = x + 7 and y = x² - 3x + 7

At the solution, the u-values are equal, which gives;

y = y

x + 7 = x² - 3·x + 7

x² - 3·x + 7 - (x + 7) = 0

x² - 4·x = 0

x·(x - 4) = 0

x = 4, or x = 0

When x = 4, y = 4 + 7 = 11

When x = 0,

         y = 0 + 7 = 7

Therefore, the solution for the equations  y = x + 7 and y = x² - 3x + 7 are are located at points: (4, 11) and (0, 7).

HERES A HARD ONE, is Annie ok?
Oksana_A [137]

Answer:

Her mistake is that she should plot the point (0, 5) first, not (1, -3)

Step-by-step explanation:

First I simplified the equation given.

y - 3 = 2 (x + 1)

y - 3 = 2x + 2

  +3         +3

y = 2x + 5

Since 5 is our y-intercept we would want to graph that first, which would be (0, 5) as a point.

Hope this helps!

A bag contains 3 red balls, 4 green balls, and 2 yellow balls. Deborah reaches into the bag and pulls out the following 4 balls:
scoray [572]

The probability that the ball Deborah picks is green is; 3/5.

<h3>What is the probability that the ball picked last is green?</h3>

Since the bag initially contains; 3 red balls, 4 green balls, and 2 yellow balls, after Deborah pulls out the 4 balls: red, red, green, yellow.

The balls remaining are; 1 red ball, 3 green and 1 yellow.

Hence, the probability that the final ball she picks is green is; 3/(3+1+1) = 3/5.

HELP! Drag each scenario to show whether the final result will be greater than the original value, less than the original value,
kogti [31]

Answer:

<u>Same as the original:</u>

-->A 15% increase followed by a 15% decrease

--> A 25% decrease followed by a 50% increase

-->A 50% decrease followed by a 100% increase

<u>Greater than the Original:</u>

-->A 20% decrease followed by a 25% decrease

<u>Less than the Original:</u>

-->A 75% increase followed by a 50% decrease

Step-by-step explanation:

<em>Example</em><u><em>#1</em></u><em>: I did 15% increase is 15% so followed by a -15%(decrease). The sale stayed the same.</em>

<em>Example</em><u><em>#2:</em></u><em> -20%+25%=5% *greater than the original</em>

<em>Example</em><u><em>#3</em></u><em>: If the percentage came to 0%, it stayed the same(same as original.) </em>

<em />

Hope this helps!!
