DEFINE VARIABLES:
x- first number
y- second number

FORM THE TWO EQUATIONS:
x + y = -149
x = y-5

PLUG IN FIRST VALUE TO FIND SECOND (order you plug in doesn’t matter):
(y-5) + y = -149

SIMPLIFY:
(y-5) + y = -149
2y -5 = -149
2y = -144
y = -72

PLUG IN SECOND VALUE TO FIND FIRST:
x + y = -149 —> y = -x-149

x = (-x-149) -5
x = -x -154
2x = -154
x= -77

WRITE FINAL SOLUTION:
(x,y)
(-77, -72)

Answer:

-72 and -77

Step-by-step explanation:

-149 divided by 2 is 74.5 and sense we want a 5 difference we divide 5 by 2 to get 2.5 the we take 74.5 and add 2.5 to get - 72 and take 74.5 and subtract 2.5 to get -77.

madreJ [45]

Answer:  a) \dfrac{799}{31250}  b) \dfrac{30451}{31250}

Step-by-step explanation:

Since we have given that

Number of days in a year = 365

Number of students = 50

Probability that no two students share the same birthday. It means each student has different birthday.  

Probability(no two students share the same birthday)=\dfrac{365-1}{365}\times \dfrac{365-2}{365}........\times \dfrac{365-50}{365}

Probability(no two students share the same birthday)=\dfrac{^{365}P_{50}}{365^{50}}

Probability(no two students share the same birthday)=\dfrac{799}{31250}\approx 0.025568

Probability that at least one of the students has the same birthday as another student in the class is given by

1-P(\text{no student share the same birthday})\\\\=1-\dfrac{799}{31250}\\\\=\dfrac{30451}{31250}=0.974432

Given the diagram below, what is cos(45")?<br> 45° 6 <br> A. √2<br> B. 6/√2<br> C. 1/√2<br> D. 3√2
Gnesinka [82]
C. 1/root2

Based on the information, the hypotenuse will be 6root2 because it is a 45, 45, 90 triangle. The two legs will be 6. Using SOH CAH TOA, we know that for cosine, it will be adjacent/hypotenuse. The adjacent side is 6 and the hypotenuse is 6root2. The result will be (6)/(6root2). After simplifying, we get
1/root2.
