Domain = 80,000
Range = 75,000
Step-by-step explanation:
Sean reads 60 minutes on wednesday
<em><u>Solution:</u></em>
Given that,
Let "x" be the number of minutes read on monday
Let "y" be the number of minutes read on tuesday
Let "z" be the number of minutes read on wednesday
<em><u>He reads 3 times as many minutes on Tuesday as he does on Monday</u></em>
Number of minutes read on tuesday = 3 times the number of minutes read on monday
y = 3x --------- eqn 1
<em><u>He reads 4 times as many minutes on Wednesday as he does on Monday</u></em>
Number of minutes read on wednesday = 4 times the number of minutes read on monday
z = 4x ------- eqn 2
<em><u>Sean reads 45 minutes on Tuesday</u></em>
y = 45
<em><u>Substitute y = 45 in eqn 1</u></em>
45 = 3x
x = 15
<em><u>Substitute x = 15 in eqn 2</u></em>
z = 4(15)
z = 60
Thus he reads 60 minutes on wednesday
This question is really hard
Answer:
(x−2)(x−4)
Step-by-step explanation:
Let's factor x2−6x+8
x2−6x+8
The middle number is -6 and the last number is 8.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get -6
Multiply together to get 8
Can you think of the two numbers?
Try -2 and -4:
-2+-4 = -6
-2*-4 = 8
Fill in the blanks in
(x+_)(x+_)
with -2 and -4 to get...
(x-2)(x-4)
Hope this helps! Also, if it's no trouble, can I have brainliest? Thanks! :D
