13. analyze relationships eli takes a typing test and types all 300 words in
hour. he takes the test a second time and types the words in hour.
waslaster or slower on the second attempt? explain.

Slower

Step-by-step explanation:

Because he's / she's already taken the test, the brain has acknowledged the pattern the test was laid in. regardless, Eli was at the exact same speed the 2nd time, meaning there was no improvement or there was degradement instead. Eli should've been faster this time, but because there was no improvement, she/he has gotten slower instead

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
