Answer:
In the first equation x=4 or x=-3
In the second equation x=-4 or x=3
Explanation:
The first equation x^2 − x − 12 can be factorized as follows:
x^2-4x+3x-12
x(x-4)+3(x-4)
x-4=0 or x+3=0
x=4 or x=-3
It is noteworthy that -x was rewritten as -4x+3x in order to solve the equation
The second equation x^2 + x − 12 can be factorized as below:
x^2+4x-3x-12
x(x+4)-3(x+4)
x+4=0 or x-3=0
x=-4 or x=3
It is noteworthy that +x was rewritten as 4x-3x in order to solve the equation
Answer:
y = 5x + 6
Explanation:
we need to things to do this, the slope and the equation of a line
slope = change in y/ change in x
change in y = (-4 - 1) = -5
change in x = (-2 - -1) = -1
-5/-1 = 5
y = 5x + b
plug in a point
1 = 5(-1) + b
b = 6
y = 5x + 6
The use of ICT for Teaching and Learning help learners to live and work in the 21st century as people do not need to go to the office but work from the comfort of their home such as online teaching.
<h3>How does Ralph Tyler see the curriculum?</h3>
Tyler is known to be a person who believed that learning is one that is always meaningful to the student and also the community at large.
He believed that, student that have been e taught through the right designed and organized method of learning will do well and that students learning should be evaluate to see if they are improving or not.

Answer:
No, it's not an exponential increase.
Explanation:
Given the following data;
Monday = 8 flu cases.
Tuesday = 12 flu cases.
Wednesday = 24 flu cases.
Thursday = 30 flu cases.
An exponential increase has a constant ratio of proportion such as 2, 4, 16, 256, etc.
To determine if the increase is exponential, we would find the ratio of each successive reports
Tuesday : Monday = 12/8 = 1.5
Wednesday : Tuesday = 24/12 = 2
Thursday : Wednesday = 30/24 = 1.25
From the above calculations, we can deduce that the ratio of increase isn't constant. Therefore, the newspaper's claim of an exponential increase is incorrect and not accurate.
