-t(5t - 7) = -5
-1 -1
t(5t - 7) = 5
t(5t) - t(7) = 5
5t² - 7t = 5
5t² - 7t - 5 = 0
t = -(-7) ± √(-7)² - 4(5)(-5)
2(5)
t = 7 ± √49 - 4(-25)
10
t = 7 ± √49 + 100
10
t = 7 ± √149
10
t = 0.7 ± 0.1√149
Answer:
m∠QRS = 52°
Step-by-step explanation:
From the given figure,
In right triangles ΔRQT and ΔRST,
QT = TS = 7.5 units [Given]
RT ≅ RT [Reflexive property]
ΔRQT ≅ ΔRST [By HL theorem of congruence]
Therefore, m(∠QRT) = m(∠SRT) = 26° [CPCTC]
m(∠QRS) = 2m(∠QRT)
= 2×(26°)
= 52°
Answer:
x + y = 6 and y = -x – 1 = (no solutions exist)
Step-by-step explanation:
Well hmmm
let's say
b = amount of buzz cuts
f = amount of flat-top cuts
now, the total price for all the buzz cuts, since each one is $9, will then be 9*b or 9b
and the price for all flat-top cuts, since each is $13, will then be 13*f or 13f
one day Jerry made a total of $600, so we know, whatever "b" and "f" are, we know their price sum was 600,
thus 9b + 13f = 600
now, Jerry "<span>knows that he cut three times as many buzzes as flat-tops", so, whatever "f" is, "b" is three times that much, or 3*f, so b = 3f
now then </span>
<span>
solve for "f"</span>
Answer:
Step-by-step explanation:
since it is parallel, the gradients are the same; m = -5/4
