a linear equation is an equation in which the highest order of exponent is 1.

your equation is:

4x - y = 7

it's a linear equation.

none of the variables has an exponent larger than 1.

x = x^1

y = y^1

to find your ordered pairs, just take 3 values for x at random and plug them into the equation.

let x = 1,2,3

your equation is:

4x - y = 7

if you solve for y, it makes it easier to find the y value given the x value.

solve for y to get:

y = 4x - 7

when x = 1, y = -3

when x = 2, y = 1

when x = 3, y = 5

placing the equation into this form also allows you to graph it.

placing the equation into this form also gives you the slope-intercept form of the equation.

what you started with was the standard form of the equation for a straight line.

that standard form is ax + by = c

your equation is:

4x - y = 7

a = 4 and b = -1

the slope intercept form of the equation of a straight line is y = mx + b

m is the slope and b is the y intercept.

when you solved for y, you placed the equation into this form.

your slope is 4

your y intercept is -7

graph of your equation looks like this:

I placed horizontal lines at y = -3, 1, 5.

If you trace a vertical line down from the intersections of those lines with the line created by your equation, you will see that the value of x at those intersection points is 1,2,3

the points on the line formed by your equation are:

(x1,y1) = (1,-3)

(x2,y2) = (2,1)

(x3,y3) = (3,5)

you can take any other values of x and find the corresponding value of y by just replacing x in the equation with the value of x.

the equation is y = 4x - 7

when x = 5, y = 20-7 = 13, etc. brainlest pls

Answers

Answer:

98 degrees

Step-by-step explanation:

Since angle LON is a straight angle, that means its measure is 180 degrees. So, the two angles that make up angle LON add up to 180. You can create the following equation:

(3x + 89) + (8x + 58) = 180

Then, add like terms.

3x + 8x = 11x

89 + 58 = 147

11x + 147 = 180

Subtract 147 from both sides.

11x = 180 - 147

Add like terms.

11x = 33

Now, divide by 11 on both sides.

x = 3

Since we now have the value of x, we can plug it into the equation to find angle MON:

MON = 3x + 89

Substitute 3 for x

MON = 3(3) + 89

MON = 9 + 89

MON = 98

Step-by-step explanation:

We know a hummingbird beats its wings 420 times in 30 seconds. To find the unit rate, divide 420 by 30.

420/30

42/3

14 beats/second

Now we know a hummingbird beats its wings 14 times in 1 second. Two minutes equals 120 seconds. Multiply 14 by 120 to get the answer here.

14 * 120

(14 * 12) * 10

168 * 10

1,680 beats

Answer:

1680

Step-by-step explanation:

From the table, we can see that per each 30 seconds, a mocking bird flaps its wings 420 times.

Each minute contains 60 seconds. Therefore, in order to calculate the number of times a mockingbird flaps its wings in 2 minutes, we can

60 seconds x 2 minutes = 120

Then, we can divide this number by 30 to figure out how many times we need to multiply 420 to get our answer.

120/30 = 4

Therefore,

420 x 4 = 1680

likelihood that best describes the probability of this event. ​

Answers

Answer:

UNLIKELY

Step-by-step explanation:

Given that:

Probability of rolling a six with a six sided nuner cube = 1/6

Required outcome / Total possible outcomes

Number of 6 / total sides of number cube = 1/6

The probability value obtained shows that there is a chance of getting a six ; however it is possible at about once in every 6 rolls of the dice.

Hence getting a six isn't impossible but the chance is small. A probability of 1/6 is the smallest that can be obtained for any of each number on the dice. Hence, it could be said that the likelihood is 'UNLIKELY'

The height of a tree when planted is 1.1m. One year later the height of the tree is 1.9m. Calculate the percentage increase in the height of the tree over a year

Answers

Answer:

72.7273%

Step-by-step explanation:

Just divide 1.9/1.1 and get 1.7273 which is equal to around 72%

The height of the tree has increased by 72% (72727273% to be exact).

The calculation to find that answer is the new height (1.9) divided by the old height (1.1).

1.9/1.1 = 1.72727273

The 1 in the answer is basically the original height, so you can ignore as we already know that the height has increased

At a book sale, all paperback books cost d dollars each and all hard books cost 2d dollars each. If Kate paid 7d dollars for 5 books at this sale, how many paperback books did she buy?

Answers

Answer:

3 paperback books

Step-by-step explanation:

Let the number of paperback Kate bought be a and the number of hard books be b.

Given that she bought 5 books then

a + b = 5

Also, If Kate paid 7d dollars then

a * d + b * 2d = 7d

Divide through by d

a + 2b = 7

Hence we have 2 equations

a + b = 5

a + 2b = 7

subtract the first from the second

2b - b = 7 - 5

b = 2

since

a + b = 5

a + 2 = 5

a = 5 - 2

= 3

Recall that the number of paperback she bought is a hence this is 3

Answer:

proportional relationship does not exist.

proportional relationship does exist.

proportional relationship does not exist.

proportional relationship does exist.

Step-by-step explanation:

To establish proportionality :

For data 1:

y α x

y = kx ; k = proportionality constant

Take x = 1 ; y = 5

5 = k

k = 5

Hence, to obtain other data points :

y = 5x (if data is proportional ; if otherwise, the data isn't proportional).

Take ; x = 2

y = 5* 2 = 10

10 ≠ 9

Hence, data isn't proportional.

2.)

Data 2:

y α x

y = kx ; k = proportionality constant

Take x = hours 2 ; y = miles = 110

110 = 2k

k = 110/2

k = 55

Take ; x = 5

y = 55*5 = 275

275 = 275 (proportional relationship exist)

3.)

For the graph:

First graph isn't proportional

4 = 2k ; k = 4/2 = 2 ; k = 2

At x = 6

y = 6*2 = 12

From graph ; y = 8 at x = 6

Hence, proportional relationship does not exist.

4.)

For the 2nd graph:

4 = 2k ; k = 4/2 = 2 ; k = 2

At x = 6

y = 6*2 = 12

From graph ; y = 12 at x = 6

Hence, proportional relationship does exist.

Sue is drawing two lines on a coordinate plane. She begins the first line at the origin and ends at (4,3). She begins the 2nd line at (0,4) and ends at (3,0). Where will these lines intersect?
PLEASE HELP

Answers

The point of intersection of the lines, if The coordinates of the first line (0, 0) and (4, 3), and The coordinates of the second line (0, 4) and (3, 0), is (1.92, 1.44).

What is a line?

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Given:

The coordinates of the first line (0, 0) and (4, 3),

The coordinates of the second line (0, 4) and (3, 0),

Write the equation of the line as shown below,

The equation of the first line,

y - 0 = 3 - 0 / 4 - 0 (x - 0)

y = 3/4 x

4y = 3x

4y - 3x = 0

The equation of the second line,

y - 0 = (0 - 4) / (3 - 0)  (x - 3)

y = -4 / 3  (x - 3)

3y = -4x + 12

3y + 4x = 12

Solve these equations,

x = 1.92 and y = 1.44

Thus, they intersect at (1.92, 1.44)
