Answer:
180
Step-by-step explanation:
Multiply 60x3
and you will get 180miles
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:
1. Lets say that you get the coords. (1,2). X would be the first one (1), and Y would be the second number (2). if you got 2/1, then, because of rise/run, that 2 would be Y and 1 would be X
2. ?
3. Slope is rise/run (Y/X), and the Y intercept is where the line intercepts the Y axis.
I literally have no idea how to answer 2, but I hope that I helped a bit :)
Step-by-step explanation:
multiply the first bracket with the second
and get -a squared -4a+3a+12
then we group like and unlike terms
so -4a+3a = -a
our new equation will be -a (squared)-a+12=0
we equals to zero to remove negative signs and it will be
a squared +a-12
then we find the factors.
And our factors are 3a-4a
=a squared +3a-4a-12=0
We factorise and answer will be
(a+3) (a-4)=0
so a = -3 or 4
