4x + 8y = -40

if x = -6

4(-6) + 8y = -40

-24 + 8y = -40

8y = -40 + 24

8y = - 16

y = -16/8

y = -2

Answer 2

Answer:

y= -2

Step-by-step explanation:

Question:

To find value of y

Equation:

4x + 8y = -40

Given,

x = -6

Solution:

=> 4x + 8y = -40

[By putting the value of x = -6 then ]

=> 4×(-6) + 8y = -40

=> -24 + 8y = -40

=> 8y = -40 + 24

=> 8y = -16

[tex] = > y = \frac{ - 16}{8} [/tex]

=> y = -2

Result:

Hence, required value of y is -2 (Ans)

Two snails climbed up a tree at a constant rate. A person measured and recorded their respective distances above the ground. • Snail A was 12.5 inches above the ground at 10 minutes and 16 inches above the ground at 24 minutes. • Snail B started at 3 inches above the ground and climbed 0.3 inch per minute. The snails continued at the same speeds. • Determine the amount of time, in minutes, it took for the two snails to be the same distance above the ground. • Include an equation to represent each snail's distance above the ground, y, in terms of x, the minutes elapsed since the measurement started. Show your work or explain your answer.

Answers

Answer:

140 minutes

Step-by-step explanation:

Using m = (y₂ - y₁)/(x₂ - x₁) , we find the rate at which Snail A moves which is also the gradient of the line with which it moves. Given that Snail A was 12.5 inches above the ground at 10 minutes and 16 inches above the ground at 24 minutes, x₁ = 10 min, y₁ = 12.5 inches, x₂ = 24 min and y₂ = 16 inches.

So, m = (y₂ - y₁)/(x₂ - x₁)

m = (16 - 12.5)/(24 - 10) = 3.5/14 = 0.25

Also, the equation of the line,

(y - y₁)/(x - x₁) = m

(y - 12.5)/(x - 10) = 0.25

cross-multiplying, we have

y - 12.5 = 0.25(x - 10)

expanding the bracket, we have

y - 12.5 = 0.25x - 2.5

adding 12.5 to both sides, we have

y - 12.5 + 12.5 = 0.25x - 2.5 + 12.5

y = 0.25x + 10

Since Snail B started at 3 inches above the ground and climbed 0.3 inch per minute. The snails continued at the same speeds, its distance y moved is y = 0.3t + 3

We now find the time x it takes the snails to cover the same distance by equating both expressions. So,

0.25x + 10 = 0.3x + 3

collecting like terms, we have

10 - 3 = 0.3x - 0.25x

7 = 0.05x

0.05x = 7

x = 7/0.05

x = 140 minutes

How many solutions does this system of equations have? Explain.
y = x + 1
y = 2x + 2

The system of equations has ... solution.

The equations have ... slopes, so the lines intersect at ... point.

Convince Me!

The equations of a system have the same slopes. What can you determine about the solution of the system of equations?

Answers

Answer:

The system of equations has one solution. The equations have different slopes, so the lines intersect at one point.

If a system of equations have the same slope, then the lines will run parallel to each other and never cross, leading to no solution being possible. Or if they have the same slope and same y-intercept (therefore being equations for the same line), they will have an infinite number of solutions.

Step-by-step explanation:

The solution to a system of equations is the point where the lines intersect. Looking at this question if we remember the slope-intercept form y=mx+b where m is slope and b is the y-intercept. We can see m=1 for the first equation and m=2 for the second equation. Anytime two equations have different slopes it is guaranteed they will intersect at some point leading to one solution.

Sue bought a total of 12 candy bars at the store. Some cents cost 50 cents each and the rest cost 75 cent each. Write an expression to represent. a. The number of 75 cent bars if she bought y 50 cent bars b. The total cost, in cents, for all of the bars.

Answers

Answer:

According to this,  the answer is:

a. x=(c-0.50y)/0.75

b. c=0.75x+0.50y

Step-by-step explanation:

With the information provided, the total cost in cents is equal to the result of the price of the 75 cent bars for the amount of bars plus the price of the 50 cent bars for the amount of bars, which would be:

c=0.75x+0.50y, where:

x is the amount of the 75 cent bars

y is the amount of the 50 cent bars

Now, you can solve for x to determine the expression that represents the number of 75 cent bars if she bought y 50 cent bars:

c-0.50y=0.75x

(c-0.50y)/0.75=x

x=(c-0.50y)/0.75

According to this, the answer is:

a. x=(c-0.50y)/0.75

b. c=0.75x+0.50y

ABCD is a parallelogram. AB = 2x, AD = 4y - 6, BC = 3x. If the perimeter of ABCD is 180, find the values of x and y

Answers

Answer and Step-by-step explanation:

AB = DC = 2x

AD = BC = 4y - 6 = 3x

180 = 2x + 2x + 3x + 3x = 10x

18 = x

4y - 6 = 3(18)

4y = 54 + 6

4y = 60

y = 15

18 = x

15 = y

2(18) + (4(15) - 6) + 3(18) + 2(18) = 36 + 36 + 54 + 54 =  180

The ratio of red to blue marbles in a bag is 2:5. If there are 65 blue marbles in the bag, how many red marbles are there? Let x represent the number of red marbles. Set up a proportion and cross multiply to solve.

Answers

Answer:

first get the total ratio; 2 + 5 = 7

so the fraction of blue marbles is 5/7

then assume the number of total marbles to be k

then use the expression;

5/7*k = 65

7*5/7 * k = 65*7

5k =455

5/5k = 455/5

k = 91

then calculate the number if red marbles from;

x = 2/7*91

x = 26

Therefore there are 26 red marbles.
