Answer:
x = 2, y = 3
Step-by-step explanation:
i) It is given that 5x - 3y =1
ii) It is also given that x = 2y - 4
iii) we can substitute the value of x from ii) in the equation in i) and we will get 5(2y - 4) - 3y = 1 ⇒ 10y - 20 -3y = 1 ⇒ 7y = 21 ∴ y = 3
iv) substituting the value of y obtained in ii) we get x = (2 × 3) - 4 = 6 - 4 = 2.
v) Therefore x = 2.
we are given
total number of stickers =24
stickers per cards =4
We are given
number of cards =x
so, we can use formula
number of cards = ( total number of stickers)/(stickers per cards)
we can plug values
so, total number of cards is 6...........Answer
Step-by-step explanation:
p=multiply 67×10^5=6700000
Q=multiply 1.55×10^-2=0.0155
(3×0.0155)÷6700000/ (1÷2)
=0.0465/ 2,588
= 0.0000179~0might be standard form

Answer:
m = 7/5
b = 7
y = 7/5x + 7
Step-by-step explanation:
points (-5,0) (0,7)
slope = (y2-y1)/ (x2-x1)
= (7-0)/(0--5)
= (7-0)/(0+5)
= 7/5
y intercept = point where it crosses the y axis (0,7)
y = mx+b
m = 7/5
b = 7
y = 7/5x + 7
To find a rational function's vertical asymyptotes, you need to find when the denominator is zero. So when is the denominator x² + 3x - 4 zero? We set that denominator equal to zero.
x² + 3x - 4 = 0
This second degree equation factors. We want a pair of numbers that multiply to 4, and there are only two pairs: 2 and 2, 1 and 4. We want the sum to 3, and one must be negative. -2 and 2 add to zero, -4 and 1 add to -3, -1 and 4 add to 3. The last one is the pair.
x² + 3x - 4 = 0
(x + 4) (x - 1) = 0
x = -4 or x = 1
So the function's vertical asymptotes are at x = 1 and x = -4.
