Write two expressions to show w increased by 4. Then, draw models to prove that both expressions represent the same thing.
Vinil7 [7]

Answer:Answer:

w + 4 and 4 + w

Step-by-step explanation:

Given phrase,

w is increased by 4,

That is, w + 4

By the commutative property of addition,

The expression would be,

4 + w

For drawing a model that shows w + 4

Take two boxes in which first shows w and second shows 4 and add them,

Similarly, for showing 4 + w, take first box that shows 4 and second box that shows w then add them.

Step-by-step explanation:

The solution of the system with two lines is the x-coordinate of their intersection point.

a. there is only a solution if the lines are identical

  • No, it gives infinitely many solutions.

b. both the x–coordinate and the y–coordinate of the intersection point,

  • No, only the x-coordinate is considered

c. the y–coordinate of the intersection point

  • No, only the x-coordinate is considered

A​ student's course grade is based on one midterm that counts as 1010​% of his final​ grade, one class project that counts as 15
snow_tiger [21]

Answer:

His overall final​ score is 81.5

He earned a B

Step-by-step explanation:

To find his overall grade, we multiply each of his grades by it's weight.

Grades:

67 on the midterm, which counts for 10% = 0.1

88 on the project, which counts for 15% = 0.15

91 on homework assignements, which counts for 40% = 0.4

72 on the final exam, which counts for 35% = 0.35.

What is his overall final​ score?

67*0.1 + 88*0.15 + 91*0.4 + 72*0.35 = 81.5

His overall final​ score is 81.5

At least 80 and less than 90 has a letter grade of B. 81.5 is in this range. So he earned a B

Graph the line that passes through the points (2, 1) and (1, -2) and determine the equation of the line.
ankoles [38]

Answer:

y = 3x - 5

Step-by-step explanation:

Slope Formula: m = \frac{y2-y1}{x2-x1}

Slope-Intercept Form: y = mx + b

Step 1: Find slope

m = (-2 - 1)/(1 - 2)

m = 3

Step 2: Find <em>b</em>

y = 3x + b

-2 = 3(1) + b

-2 = 3 + b

b = -5

Step 3: Rewrite linear equation

y = 3x - 5

Step 4: Graph using graphing calc
