Slope formula: (y² - y¹) / (x² - x¹)
(-3, -1) (2, 4)
x¹ = -3
x² = 2
y¹ = -1
y² = 4
4 - (-1) = 5
2 - (-3) = 5
5/5 = 1
So the slope is 1.
Hope this Helps!!
I have encountered this question before. Since only the product of the ages is given, there are a lot of possible combinations.
3 kids, has a youngest child - means that the 3 kids have different ages.
I performed a prime factorization on 72.
72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1
1 x 2 x 2 x 2 x 3 x 3 = 72
Possible age combination:
1 x 8 x 9 = 72
2 x 4 x 9 = 72
3 x 4 x 6 = 72
1 x 6 x 12 = 72
1 x 4 x 18 = 72
Answer:
x/y = 88/7
Step-by-step explanation:
x+y=19
x+3y=12y+5
First rewrite second equation as:
x +3y-12y = 5
Combine like terms:
x-9y = 5
Now you have:
x+y=19
x-9y = 5
Elimination method Subtract 2 equations:
10y = 14 Divide both sides by 10
y = 14/10 = 7/5
Plug in y in any given equation and calculate x:
x+ 7/5 = 19 Subtract 7/5 from 19
x = 88/5 = 17 3/5
x/y = 88/5 : 7/5
Answer:
200.65
Step-by-step explanation:
147 plus 75% or 110.25 minus 22% or 56.59
Cevap:
-1
Adım adım açıklama:
F (x) = 3cos2x-2sinx fonksiyonu verildiğinde, f (3π \ 2) bulacağız.
Vekil;
f (3π / 2) = 3kos2 (3π / 2) -2sin (3π / 2)
f (3π / 2) = 3cos3π - 2sin (3π / 2)
f (3π / 2) = 3 (-1) -2 (-1)
f (3π / 2) = -3 + 2
f (3π / 2) = -1
Dolayısıyla f (3π / 2) değeri -1'dir
