Determine whether each equation has one solution, no solution or infinitely many solutions. 4x + 10 = 2(2x + 5) 4x - 5 = 4x + 10

sdas [7]

Answer:

see below

Step-by-step explanation:

4x + 10 = 2(2x + 5)

Distribute

4x+10 = 4x+10

Since the left side is identical to the right side, there are infinite solutions

4x - 5 = 4x + 10

Subtract 4x from each side

-5 = 10

This is never true, so there are no solutions

4x-5 = -5

Add 5 to each side

4x = 0

x=0

There is one solutions

403010Pa2 4 8 10Number of ticketsThe graph shows the cost of buying raffle tickets.19. write an equation shows the cost y in ter

Lana71 [14]

Simple..

you have y which is the cost of the tickets..and you have x which is the number of tickets..

So, you have those points on the graph....find an equation!

Take any of those coordinates..and find the equation of the line...in the form of y=mx+b

(2,10) and (5,25)

Using: $\frac{ y_{1}- y_{2} }{ x_{1}- x_{2} }$

$\frac{10-25}{2-5} = \frac{-15}{-3} =5$

Thus, you know your slope. m=5

But, remember it's in the form of y=mx+b

So, use any of the coordinates...let's use (2,10)

10=5(2)+b

10=10+b

0=b

Thus, your equation is... y=5x

Thus, your answer.

1. Ifp=7,9 =-6, r = 10 and s=-4, calculate:

Ratling [72]

the answers as follows

a) 16 b) 13 c) 16 d) 46 e) -630 f) 18 g) -32 h) 50 i) -6 j)38 l)61

Step-by-step explanation:

a) p + 9 = 7 + 9 = 16

b) p - s = 7 - (-4) = 7 + 4 = 13

c) r - q = 10 - (-6) = 16

d)q + 52 = -6 + 52 = 46

e) pqr = 7 X (-6) X 10 = -630

f) r + 8 = 10 + 8 = 18

g) pq + r = 7 X (-6) + 10 = -42 + 10 = -32

h) r - qs = 10 - (10 X (-4))= 10 + 40 = 50

i) 3r + 6q = 3 X 10 + 6 X (-6) = 30 - 36 = -6

j) 59 - 3p = 59 - 3 X 7 = 59 - 21 = 38

k) check your question

l) 4q + 85 = 4 x (-6) + 85 = -24 + 85 = 61

What's the domain and range function for y=(x-12)^2+11

aev [14]

Answer:y = x 2 − 12 x The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. Interval Notation: ( − ∞ , ∞ ) Set-Builder Notation: { x | x ∈ R } The range is the set of all valid y values. Use the graph to find the range. Interval Notation: [ − 36 , ∞ ) Set-Builder Notation: { y | y ≥ − 36 } Determine the domain and range. Domain: ( − ∞ , ∞ ) , { x | x ∈ R } Range: [ − 36 , ∞ ) , { y | y ≥ − 36 }
