Write an equation for a line through (-2,4) with m= -4 in standard form.
A)4x + y = - 4
B)4x - y = - 4
C)-4x - y = 4
D)-4x + y = - 4

Answers

Answer 1

Answer:

4x+y=-4

Step-by-step explanation:

gradient(m)=y2-y1/x2-x1

the line also passes through points (x,y) and (-2,4)

-4=4-y/-2-x

cross multiplying

8+4x=4-y

option(A):4x+y=-4

is your answer.

Rewrite 6/5 as a mixed number.

Answers

6 goes into 5 1 time and then you’ll have 1 left over so it would be 1 1/5

Answer:

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 6 by 5 and keep only what is to the left of the decimal point:

6 / 5 = 1.2000 = 1

Step 2 - Find New Numerator

the answer from Step 1 by the denominator and deduct that from the original numerator.

6 - (5 x 1) = 1

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 6/5 as a mixed number is:

Calculate the perimeter of the semi-circle shown below. Use 3.14 to approximate n.

Answers

Answer:  25.7 cm

========================================================

Explanation:

A full circle of radius r has the circumference of

C = 2*pi*r

A semicircle will have us divide this value in half

2pi*r turns into pi*r

The curved distance along the top is roughly pi*r = pi*5 = 3.14*5 = 15.7 cm.

Add this onto the straight line distance along the bottom to arrive at 15.7+10 = 25.7 cm

what is the range of this piecewise function

Answers

Answer as a compound inequality: [tex]-4 \le y < 2[/tex]

Answer in interval notation:  [-4, 2)

=============================================

Explanation:

The range is the set of all possible y outputs of a function. When dealing with a graph like this, we just look at the highest and lowest points to determine which y values are possible.

The lowest point occurs when y = -4. We include this value. So far we have [tex]y \ge -4[/tex] which is the same as [tex]-4 \le y[/tex]

The upper ceiling for the y value is y = 2. We can't actually reach this value because of the open hole at (-3,2). So we say that [tex]y < 2[/tex]

Combine [tex]-4 \le y[/tex] and [tex]y < 2[/tex] to get the compound inequality [tex]-4 \le y < 2[/tex]

This says y is between -4 and 2, including -4 but excluding 2.

To convert this to interval notation, we write [-4, 2) where the square bracket says to include the endpoint and the curved parenthesis says to exclude the endpoint.

pls give me the correct answer and solution thank you​

Answers

Answer:

C 13

Step-by-step explanation:

2 right-angled triangles. so, Pythagoras applies for both.

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90° angle).

starting with the small triangle we have

5² = 3² + x-part²

x-part² = 5² - 3² = 25 - 9 = 16

x-part = 4 cm

the markers indicate that x-part as the third side of the small triangle is exactly as long as the other part of x.

that means

x = 2 × x-part = 2 × 4 = 8 cm

for the large triangle we then get

y² = x² + 15² = 8² + 225 = 64 + 225 = 289

y = 17 cm

and so,

y - x = 17 - 8 = 9

but that is not an answer option.

and now it dawned on me : x was not meant to be the whole third side of the large triangle. x is supposed to be only the upper part of that side, above the small triangle.

in essence, x is what I originally called "x-part".

so, the Pythagoras calculations remain basically the same, but we should name things differently like

5² = 3² + small-side²

small-side = 4 cm

x = small-side = 4 cm

long-side = 2 × small-side = 2 × 4 = 8 cm

y² = long-side² + 15² = 8² + 15² = 64 + 225 = 289

y = 17 cm

and the actual y - x = 17 - 4 = 13 cm

what is the area , in square feet , of the shaded part of the rectangle below?​

Answers

Answer:

208 square feet

Step-by-step explanation:

Area (shaded) = Area (rectangle) - Area(triangle)

= (17 x 16) - 1/2(16 x 8)

= 16 (17 - 4)

= 16 (13)

= 208 square feet

can someone pls explain how to answer this?

Answers

Answer:

HOPE THIS HELPS

Step-by-step explanation:

You need to first plot the points on the graph.

Since, it says you need to reflect across x axis, you need same number of square units.

For example, P has the coordinates( -2,3 ). -2 lies on the x axis, so the point doesn't go neither left nor right. It is 3 squares above the x axis, so the reflected point should be 3 squares below the x axis. Likewise, you can do the other points.

Hope it helps :)

There is a bag filled with 6 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 reds?

Answers

Answer:

Step-by-step explanation:

The first probability of it being red = 5/11

The key to the question is that you replace the red marble you took out. So there are still 5 red marbles.

You still have a 5/11 chance of getting a red marble.

P(red + red) = 5/11 * 5/11

Answer

P(red + red) = 25 / 121

if 300 people come to the gym on a given day, approximately how many people would you expect to exercise for more than 136 minutes?​

Answers

Answer:  120

===========================================================

Explanation:

Add up the numbers in the second column:

4+19+25+32 = 80

There are 80 people being surveyed in the table.

Of those 80 people surveyed, 32 of them exercised for more than 136 minutes.

The probability of selecting someone who exercised for more than 136 minutes is the fraction 32/80 = (16*2)/(16*5) = 2/5

----------

Multiply this probability with the larger sample size of 300 to get

(2/5)*300 = 0.4*300 = 120

We estimate that 120 people would exercise for more than 136 minutes.

Note that 120/300 = 2/5.

You work with a carpenter who asks you to cut trim board in the following lengths: 71/2 inches,
101/2 inches, 9 inches, and 51/2 inches. To do this using only one piece of trim board, how long
must the board be?

Answers

Answer: 32 1/2

Explanation: add up all the fractions

7 1/2 + 10 1/2 + 9 + 5 1/2
18 + 9 + 5 1/2
27 + 5 1/2
32 1/2

Length of board will be 32 1/2 inch.

What is Addition?

A process of combining two or more numbers is called addition.

Given that;

Length of board after cutting are;

7 1/2 inches, 10 1/2 inches, 9 inches, and 5 1/2 inches.

Now, Total length of board is calculated as sum of all cut lengths.

So, Total length of board = 7 1/2 +10 1/2 + 9 + 5 1/2

                                      = 15/2 + 21/2 + 9 + 11/2

                                      = 47/2 + 9

                                      = 65/2

                                      = 32 1/2

Thus, Length of board will be 32 1/2 inch.

We have the graph of the function f(x).

We want to determine which of the given is true of the graph from [tex]x=g[/tex] to [tex]x=\infty[/tex].

So, essentially, we are focusing on the last curve (see image below).

First, since the curve is above the x-axis, the curve is positive.

Second, since the curve is curving upwards, this means that it must be increasing. Another way to think about this is to think about the slope of our curve. While we can't calculate the exact slope, the average slope will be positive, so our function is increasing.

So, our answer is A.
