Find the equation of a line that is parallel to this line and passes through the point (4,0). Which of the following points are

satela [25.4K]

Answer: A and D

Step-by-step explanation:

To find the line that is parallel to the given line, we must find the slope of the original. Parallel lines NEVER touch or cross. That tells us the slope MUST be the same. To find the slope, we use the formula $y=\frac{y_2-y_1}{x_2-x_1}$ .

$y=\frac{4-0}{0-(-1)} =\frac{4}{1} =4$

With the slope, we can form an equation for the line.

y=4x+b [plug in given point]

0=4(4)+b [multiply]

0=16+b [subtract both sides by 16]

b=-16

Now that we have the y-intercept, we can find the equation.

y=4x-16

After plugging in each point into the equation, we know that A and D are correct points on the line.

Estimate √53 between two numbers to the tenths place.

uysha [10]

Answer:

√53 lies between 7.2 and 7.3

Step-by-step explanation:

To estimate the √53 between two numbers to the tenths place, the steps include

1.) Identify perfect squares that bound the number 53: 7² = 49 and 8² = 64

2.) Estimate between two whole numbers: between 7 and 8

3.) Determine the closer whole number: the root is closer to 7 because 53 is closer to 49 than to 64.

4.) Find the squares of tenths:

7.1²= 50.41

7.2²= 51.84

7.3²= 53.29

7.4²= 54.76

Hence, it is evident that √53 lies between 7.2 and 7.3

It is also clear that the required square root is closer to 7.3 than 7.2 though.

Hope this Helps!!!

Tyrone likes to snack on his big bag of candy. He takes 8 pieces of candy from the bag each time he snacks. After eating 18 snac

Anna71 [15]

<h3>c = 150 - 8s is the required function</h3>

<em><u>Solution:</u></em>

Given that,

Tyrone takes 8 pieces of candy from the bag each time he snacks

After eating 18 snacks, there are only 6 pieces of candy remaining in the bag

The number c of pieces of candy remaining in the bag is a function of s, the number of snacks Tyrone eats.

Therefore,

"c" is the number of pieces of candy remaining in the bag

"s" is the number of snacks Tyrone eats

Thus,

total number of candy in the bag = $18 \times 8 + 6 = 150$

Remaining candy in the bag = Total candy - candy he ate

c = 150 - 8s

Thus the function is found
