Answer:
I think the equation is 7l +5=60
Step-by-step explanation:
Answer:
Step-by-step explanation:
30 ≤ 23 + x
7 ≤ x
There’s an invisible 1 in front of the minus sign and an invisible 1 in front of the variable.
-1(r+4)=-3 —> -1 times 1r = -1r. -1 times 4 = -4
Multiply inside the parentheses.
-1r-4=-3
Now add 4 to both sides.
-1r-4=-3
+4=+4
-1r = 1
Now divide
R= -1
Answer:
Step 4
part a: no answer yet still having trouble showing my work
part b:
-0.125(x-24)^2+50
-0.125(x-24)(x-24)+50
-0.125(x^2-24x-24x+576)+50
-0.125(x^2-48x+576)+50
-0.125x^2+6x-75+50
-0.125x^2+6x-22
a=-0.125
b=6
c=-22
part c: yes he went through
part d:
plug in roots (4,0) and (44,0)
if x is 4 and y is 0
0=-0.125(4)^2+6(4)-22
0=-2+24-22
0=-2+2
0=0
if x=44 and y=0
0=-0.125(44)^2+6(44)-22
0=-242+264-22
0=-242+242
0=0
Answer:
A and C
Step-by-step explanation:
for A
QT/RT=ST/QT=QS/QR
There are two QT's in this
so
(QT)^2 = RT * ST
FOR B
there is no RT twice
for C
QR/RT RS/QR
There is a QR twice
so QR^2=RT*RS
FOR D there is no RT twice
(if you have the other answers for this quiz plz give them to me lol)
