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

idk

step-by-step explanation:

your victory is right around the corner. never give up.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
