Solve for c by simplifying both sides of the equation, then isolating the variable.

Exact form: c = -4/9, 2

Decimal form: c = -.4, 2

Which equation describes a line parallel to y= 4x+ 5 through point (-2, 1)?​
Keith_Richards [23]

The line parallel to y= 4x+ 5 passing through point (-2, 1) is y = 4x + 9

<h3>Parallel Equations</h3>

The given equation is:

y = 4x + 5

Compare y = 4x + 5 with the equation y = mx + c

m = 4, c = 5

The equation parallel to y = 4x + 5 will also have a slope, m = 4

The point-slope form of the equation of a line is given as:

y - y₁ = m(x - x₁)

substitute m = 4, x₁ = -2 and y = 1 into the equation above

y - 1 = 4(x - (-2)

y - 1 = 4(x + 2)

y - 1 = 4x + 8

y = 4x + 8 + 1

y = 4x + 9

Therefore the line parallel to y= 4x+ 5 passing through point (-2, 1) is y = 4x + 9

Two groups of friends go to a movie. Each ticket costs the same amount. One group spends ​$57. The other group spends ​$95. List
kenny6666 [7]

Answer:

1) All possible number tickets for group that spends $57: A, B, C, D

2) All possible number tickets for group that spends $95: B, C, E, F

3) Each ticket will cost at most $19

Step-by-step explanation:

We are told that one group spends $57 dollars while the other group spends $95.

Now,we want to find all possible whole number ticket prices for each group and at most how much each ticket​ costs.

To do this, let's first find the factors of both amounts which will give us all possible whole number ticket prices for each group.

57: 1, 3, 19, 57

95: 1, 5, 19, 95

Since each ticket costs same amount, to find out at most how much each ticket costs, we will select the highest common factor of both groups which is 19.

Thus,each ticket will cost at most $19

Explain how to use a graph of the function f(x) to find f(3)​
fenix001 [56]

Answer:

Just find the coordinate at the point where the x-coordinate is 3

Step-by-step explanation:

F(x) is just another term for Y. The variable of X is the value that you input into the f(x), which just stands for a function. Since the value that they asked for was 3, you know that they inputted the value of 3 as x. Just look where the coordinate at the point where the x-coordinate is 3 to find the answer.

A river is flowing at the speed of 2 miles per hour. A kayaker moves 528 feet upstream in 20 minutes. At this rate, how fast wou
CaHeK987 [17]
D=rt
r=(boatrate+riverrate)=(x+2)mph

d=528ft=528/5280mi=1/10mi
t=1/3hr
remember to keep the same units
so

1/10=(x+2)(1/3)
times both sides by 3
3/10=x+2
minus 2 or 20/10
-17/10=x
-1.7=x
it would be going -1.7mph (means going backwards)

Greg's grocery store placed an order for yogurt. The store ordered 1,020 cartons of yogurt. Each carton ordered was blueberry, P
marin [14]

Answer:

  544

Step-by-step explanation:

The ratios of cartons are ...

  B : P = 2 : 1

  S : L = 2 : 1

  L : B = 2 : 1

Combining these into a single set of ratios, we have ...

  S : L : B : P = 8 : 4 : 2 : 1

Then the proportion of the order that is strawberry is ...

  8/(8+4+2+1) = 8/15

and the number of strawberry cartons is ...

  (8/15)·1020 = 544

The store ordered 544 cartons of strawberry yogurt.
