Answer:
y = -5/14x + 12
Step-by-step explanation:
add 14y to both sides to isolate variables and divide everything by 14 to get 1y and boom
I believe the answer is .09625 hours
Explanation: first you do 2.2 x 105= 231
Then you do 231/40=5.775 to get how many minutes it takes to type 231 words. Then u divide 5.775/60 to get how many hours it would take.

Not trying to take points but it is too blurry I can’t see it
Step-by-step explanation:
11x+3y=103 and y=3x+1.
11x+3(3x+1)=103 -----> plug in (3x+1) for y in the first equation. You will want to distribute the 3 to the 3x+1 to get something that looks like:
11x+9x+3=103 ------> now you want to combine like terms
20x+3=103 ---> subtract 3 from both sides
20x=100 ----> divide both sides by 20
x=5
y=3(5)+1 ---> I like to plug in this to the equation that already has y isolated. 3*5 is 15, add 1 and you find that y=16.
(5, 16) will be your final answer (:
Step-by-step explanation:
radius(CE)=diameter/2=9
EF=8inch
DE=8/2=4inch
pythagorean theorem:
im right triangle,
a^2+b^2=c^2
4^2+b^2=9^2
16+b^2=81
b^2=81-16
b^2=65
b=√65
√65≈8.06
