Answer:

  lower left

Step-by-step explanation:

We notice that the answer choices have only the first equation changed. The equivalent of the first equation must have the same ratios of coefficients.

  x-coefficient : y-coefficient : constant

  = 2 : 1 : -15 . . . . . in the given equation

  2 : -2 : 30 = 1 : -1 : 15 . . .  upper left — not the same

  -4 : -2 : -15 = 4 : 2 : 15 . . . upper right — not the same

  -4 : -2 : 30 = 2 : 1 : -15 . . . lower left — same as the given equation

  -4 : 1 : 30 = 4 : -1 : -30 . . . lower right — not the same

Answer:

Since g(x) = f(2x), this means we substitute 2x in place of x for f(x):

g(x) = f(2x) = (2x)² = 4x²

Graphing this, the parabola is not moved from the parent graph f(x) = x², but the graph is compressed horizontally by a factor of 4.Step-by-step explanation:

Answer:

I believe it would be 15 copies.

Step-by-step explanation:

Store W gives you unlimited copies for 5 dollars, so the number of copies doesn't matter for store W, they do not affect the cost. So, you will have to find how many copies from store Z will cost 5 dollars. Now, it tells you store Z charges 2 dollars for the use of the machine, so you can go ahead and subtract 2 from 5 (total amount to make it equal). That being done leaves you with 3 dollars for the copies themselves, it tells you each copy costs $.20. So, now all you have to do is divide 3 by 0.20, which gives you 15.

Answer:

Step-by-step explanation:

Given points

let ( x1, y1 ) = ( - 2 , 2) and (x2 , y2 ) = (7, 3)

slope of the line (m)

= ( y2 - y1) / (x2 - x1)

= ( 3 -2 ) / ( 7 + 2)

= 1 / 9

Answer:

∠ B = 54°

Step-by-step explanation:

The angles are supplementary, that is they sum to 180° , then

7x + 14 + 5x - 26 = 180 , that is

12x - 12 = 180 ( add 12 to both sides )

12x = 192 ( divide both sides by 12 )

x = 16

Then

∠ B = 5x - 26 = 5(16) - 26 = 80 - 26 = 54°

Answer:

Z + 12

Step-by-step explanation:

Z-(-12)

Answer:

∠b=35

Step-by-step explanation:

Hello There!

Complementary angles add up to equal 90

so to find the measure of angle B we subtract the given angle from 90

90-55=35

so we can conclude that ∠b = 35

Answer:

x > −2

Step-by-step explanation:

You need to isolate the variable. You can do this by first subtracting 3/2 from both sides of the inequality sign.

You will get -x/2 < 2/2.

Next, since x is being divided by -2, you will multiply it by -2 to undo it. Do this to both sides.

Note that when multiplying or dividing by a negative you will flip the inequality sign. '<' becomes '>' and '>' becomes '<'.

You will get x > -2.

Answer:

Număr de trandafiri = x = 5 trandafiri

Numărul este garoafe = y = 8 garoafe

Step-by-step explanation:

Pasul 1

Să reprezentăm:

Costul garoafelor = c

Costul trandafirilor = r

Victor are 60 de lei și merge la florărie să-i cumpere mamei sale un buchet de flori.

Dacă ar cumpăra 9 garoafe și 4 trandafiri, ar plăti 47 de lei.

Prin urmare,

9c + 4r = 47 ..... Ecuația 1

Dacă ar cumpăra doar trandafiri, toți banii ar fi suficienți pentru 12 bucăți.

Prin urmare,

12 trandafiri = 60 lei

1 trandafir = r lei

Cross Multiply

12r = 60 lei

r = 60 lei / 12

r = 5 lei

1 trandafir costă 5 lei

Înlocuim 5 cu r în ecuația 1

9c + 4 × 5 = 47

9c + 20 = 47

Colectează ca termeni

9c = 47 - 20

9c = 27

c = 27/9

c = 3 lei

Costul unei garoafe este de 3 lei

Pasul 2

Dar cumpără 13 flori (garoafe și trandafiri) și rămâne cu 5 lei rămași,

60 lei - 5 lei = 55 lei

Asta înseamnă că a cheltuit 55 de lei pe 13 flori.

Lasă

Număr de trandafiri = x

Numărul este garoafe = y

x + y = 13 ......... Ecuația 1

x = 13 - y

Din moment ce, Costul unei garoafe = 3 lei și 1 trandafir = 5 lei

3x + 5y = 55 ...... Ecuația 2

Înlocuim 13 - y cu x în ecuația 2

3x + 5y = 55

3 (13 - y) + 5y = 55

39 - 3y + 5y = 55

Colectează ca termeni

- 3y + 5y = 55 - 39

2y = 16

y = 16/2

y = 8

Rezolvarea pentru x

x = 13 - y

x = 13 - 8

x = 5

Prin urmare:

Număr de trandafiri = x = 5 trandafiri

Numărul este garoafe = y = 8 garoafe

Answer:

Answer: y=-3x+5

Step-by-step explanation:

First write in point slope form, y-y1=m(x-x1) which is y-2=-3(x-1). Then distribute the -3 and add the negative 2 to the other side to solve for y.

Answer:

m = 90/80 = 9/8

Step-by-step explanation:

If you meant the line through the origin (0, 0) and (80, 90), then the change in x is 80 and that in y is 90.  The slope is m = (change in y) / (change in x), or

m = 90/80 = 9/8
