Answer:
20
Step-by-step explanation:
PEMDAS!!!
13 - 2(-14) ÷ 4
13 - [(-28) ÷ 4]
13 - (-7)
13 + 7 = 20
144 times 23 = 3312
you can also use a calculator too I hope I helped :)
Hey there!
When you have a number you are starting with that is your 100%. If he next number you have is higher it's going to be more than 100%, and if the other number is less it's going to be less than 100%. Since Tuesday's speed is twice as fast as Monday's, her speed increased by 100%
Hope this helped, have a good one :)
Divide both sides by 5
5x + 2 = 57/5
Subtract 2 from both sides
5x = 57/5 - 2
Simplify 57/5 - 2 to 47/5
5x = 47/5
Divide both sides by 5
x = 47/5/5
Simplify 47/5/5 to 47/5 * 5
x = 47/5 * 5
Simplify 5 * 5 to 25
<u>x = 47/25</u>
If x = -1, 0, 1, 2, 3
then y = -9, -6, -5, -6, -9
vertex: (1,-5)
focus: (1,-21/4)
axis of symmetry: x=1
directrix: y=-19/4
