Answer:
A
Step-by-step explanation:
From the graph, we can see that the <em>temperature increased initially</em>, then <em>started to decrease</em>. <u>All of these NOT in a constant rate, though</u>.
Roughly, the temperature was increasing from start till around 5.5 hours. Then on the temperature decreased.
So we can eliminate B, C, and D. That leaves us with correct answer as A.
Module 4, students extend what they already know about unit rates and proportional relationships to linear equations and their graphs. Students understand the connections between proportional relationships, lines, and linear equations in this module. Students learn to apply the skills they acquired in Grades 6 and 7, with respect to symbolic notation and properties of equality to transcribe and solve equations in one variable and then in two variables.
The student materials consist of the student pages for each lesson in Module 4.
The copy ready materials are a collection of the module assessments, lesson exit tickets and fluency exercises from the teacher materials.
Answer:
75% of a circle
Step-by-step explanation:
Hey there!!
In order to find the slope, let's convert this equation which is in a standard form to a slope-intercept form.
Slope intercept form:
<em>y = mx + b </em>
We have two things to remember:
- 'm' in the equation stands for slope.
- 'b' in the equation resembles y-intercept.
Given:
4x - 5y = -5
The main idea:
- We will have to isolate 'y'
First, let's subtract 4x on both sides:
4x - 5y - 4x = -4x -5
-5y = - 4x - 5
Now let's divide both the sides with -5
-5y/-5 = (-4x/-5) + (-5/-5)
y = (4/5)x + 1
Now, we got the slope intercept form and the coefficient of 'x' would be the slope.
<u><em>Hence, the slope of the line is '4/5' </em></u>
Hope it helps!
Step-by-step explanation:
-3x - 7y = -63
-(3x + 7y) = -63
3x + 7y = -63/-1
3x + 7y = 63
Value of x
3x + 7y = 63
3x = 63 - 7y
x = (63 - 7y)/3
Value of y
3x + 7y = 63
7y = 63 - 3x
y = (63 - 3x)/7
