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
Suppose f(x)=x^2 what is the graph of g(x)=f(2x)
i have seen other descriptions saying that you should substitute 2x into the equation, but where does that 2x come from and what is next?
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:

victor are 60 de lei si merge la florarie pentru a-i cumpara mamei sale un buchet de flori. daca ar cumpara 9 garoafe si 4 trandafiri, ar plati 47 de lei. daca ar cumpara doar trandafiri, toti banii i-ar ajunge pentru 12 bucati. insa el cumpara 13 flori (garoafe si trandafiri) si ramane cu 5 lei rest, cate garoafe si cati trandafiri a cumparat victor?
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

Solve the given inequality and graph the solution on a number line. -x/2 + 3/2 < 5/2
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.
∠aangle, a and ∠ b ∠bangle, b are complementary angles. ∠ a ∠aangle, a measures 5 5 ∘ 55 ∘ 55, degrees. What is the measure of ∠ b ∠bangle, b?
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

What's the slope of the line (80,90)
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
What is the slope of the line that passes through the points (-2,2) and (7,3)
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
hope it helps :)
If the slope is -3 and (1, 2) is a point on the line, what is the equation of the line?
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:
∠ 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°

Sam is needing to make copies of a flyer for his new business. Store W charges $5 for unlimited copies and store Z charges $0.20 per copy and $2 for using the machine.
How many copies makes both stores cost the same amounts?
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.
