Its midpoint please help

Answers

Answer 1

Answer:

(-9,-9)

Step-by-step explanation:

B = (-9,-9)

A = (9,-3)

Midpoint M = (0,-6)

Answer 2

Step-by-step explanation:

Here,we have,

(x, y) =M(0,-6)

(x1, y1) =A(9,-3)

(x2, y2) =coordinates of B=?

Using midpoint formula, we get,

x=x1+x2÷2

or, 0=9+x2÷2

or, 0×2=9+x2

or, 0-9=x2

or, x2=-9

therefore, x2=-9

Now,

y=y1+y2÷2

or, -6=-3+y2÷2

or, -6×2=-3+y2

or, -12+3=y2

or, y2=-9

therefore, y2=-9

Hence, the coordinates of B are (-9, -9)..

2= 2.27- m/4

How do I do this?! I need this for mathematics homework!

Answers

Answer:

1.08 = m

Step-by-step explanation:

2= 2.27- m/4

Subtract 2.27 from each side

2-2.27= 2.27-2.27- m/4

-.27 = -m/4

Multiply each side by -4

-.27 * -4 = -m/4 *-4

1.08 = m

Answers

Step-by-step explanation:

Use the distance formula:

(x2, y2) with (x1, y1)

[tex] d \: = \sqrt{( x2 \: - \: x1) {}^{2} \: + \: (y2 \: - \: y1) {}^{2} } [/tex]

Find the lengths of each segment one at a time.

For AC:

A(-3,8) C(0,2)

[tex]d = \sqrt{( - 3 - 0) {}^{2} + (8 - 2) {}^{2} } [/tex]

[tex]d \: = \sqrt{9 + 36} [/tex]

[tex]d \: = \sqrt{45} = 3 \sqrt{5} [/tex]

For BC:

B(6,5) C(0,2)

[tex]d \: = \sqrt{(6 - 0) ^{2} + (5 - 2) {}^{2} } [/tex]

[tex]d \: = \sqrt{36 + 9} [/tex]

[tex]d \: = \sqrt{45} = 3 \sqrt{5} [/tex]

For CD:

C(0,2) D(2,-4)

[tex]d \: = \sqrt{(0 - 2) {}^{2} + (2 - ( - 4)) {}^{2} } [/tex]

[tex]d \: = \sqrt{4 + 36} [/tex]

[tex]d \: = \sqrt{40} = 2 \sqrt{10} [/tex]

With all the segment lengths found, we can conclude that segments AC and BC have the same lengths.

Mr. Hayes has 111 straw bundles to use for bedding in his horse stalls.What is the greatest number of stalls he can fill if each stall holds exactly 4 bundles of straw?

Answers

111 straw bundles / 4 per stall = 27.75
However, you can’t technically have a .75 of a stall, so you round down to the nearest whole number, which is 27.

Which represents a unit rate ?

A. The cost of cat food is $36 per 3 bags
B. The cost of orange juice is $3 per jug
C. The cost of photocopies is $1 per 10 pages
D. The cost of roses is $50 per 2 dozen

Answers

B. The cost of orange juice is $3 per jug

A unit rate, in terms of mathematics, is a rate per unit.

Examples of unit rates are:

The car travels 25 km per hour

The cost of bags of apples is $6.00 per bag of apples.

The unit rate in these choices is Choice B:

The cost of orange juice is $3 per jug

The other choices are rates, not unit rates.

B, unit rate means the cost of one item so in option A it’s the cost for three bags not one item/bag, in option B it’s the cost of one jug so that would be your answer but we could check it with the rest. Option C is the cost per 10 pages not one so that choice is eliminated, choice D is per two dozen not one so that choice is also eliminated

(b) lim x→3 g[f(x)]

Answers

Answer:

a) 23 and b) 13

Step-by-step explanation:

I. If f(g(x)) is composit function

Find fog and gof

fog = 3(g) - 1

= 3(x+5) -1

= 3x + 15 -1

= 3x + 14

gof = (f) + 5

= (3x - 1) +5

= 3x + 4

II. Fill in a) and b) question

lim x -> 3 fog

= 3(x) + 14

= 3(3) + 14

= 9 + 14

a) = 23

lim x-> 3 gof

= 3x + 4

= 3(3) + 4

= 9 + 4

b) = 13

what is six over seven times two and three over fourteen?

Answers

The answer is 72 if you mean two multiplied by three by fourteen

and seven is equal to six times a number.

Word problems can be tricky no matter what level of math or science you are in.

First look at the question for words that indicate mathematical symbols.

"times" indicates multiplication

"and" indicates addition

"a number" means we have a variable, x, to solve for

Now we can go from left to right and write it in a mathematical equation

7x + 7 = 6x

Then, solve for x

7x + 7 = 6x

7 = 6x - 7x

7 = -1x

7/-1 = x

x = -7

Finally, we check our work.

7x + 7 = 6x

7(-7) + 7 = 6(-7)

-49 + 7 = -42

-42 = -42 √

The answer is x = -7

First thing you do in word problems : choose a variable for unknown, what problem is asked you to find.

n the number

7n 7 times the number

7n + 7 7 times the number and 7

Then the problem says it is equal 6n , make the equation

7n + 7 = 6n

and solve:

7n - 6n = -7

n = -7 / is the answer

Seven times a number and seven is equal to six times a number.

Step 1: Translate the verbal to Algebra.

7x + 7 = 6x. ("And" means addition if no other operation is present.)

Step 2: Solve for x.

7x - 6x + 7 = 6x - 6x. (subtract 6x from both sides)

1x + 7 = 0. (Simplify)

1x + 7 - 7 = 0 - 7. (subtract 7 from both sides)

1x = -7. (Simplify)

1x/1 = -7/1. (Divide both sides by 1)

x = -7. (Simplify)

Step 3: Check 7 times the number -7 and 7 is equal to six times the number -7.

7(-7) + 7 = 6(-7)

-49 + 7 = -42

-42 = -42. (Both sides are equal!)

The number again is -7.

Hi Alyson;

7x+7=6x

Let's subtract 7x from both sides...

7x+7-7x=6x-7x

7=-x

Let's multiply both sides by -1...

(-1)(7)=(-1)(-x)

-7=x

Let's check our work...

7x+7=6x

[(7)(-7)]+7=(6)(-7)

-49+7=-42

-42=-42

We have $100.75 to spend.

Each spool costs $3, and we have 24 spools.

3×24=72

Each glue costs $1 and we have 7 packages of glue.

7×1=7

We add up these expenses.

72+7=79

And we subtract from our total amount.

100.75-79=21.75

1 glue cost $1

so 7 package glue cost =7X1= $7

money that he left is equals to 100.75- 79

C. Find the equation of the line perpendicular to
y = 14x-5 and passing through (2,-3).

Answers

Answer:

[tex]y = -4x + 5[/tex]

Step-by-step explanation:

We want to find the equation of the line that is perpendicular to:

[tex]\displaystyle y = \frac{1}{4} x - 5[/tex]

And which passes through the point (2, -3).

Recall that the slopes of perpendicular lines are negative reciprocals of each other.

In other words, since the slope of the original line is 1/4, the slope of the perpendicular line will be -4.

We are also given that it passes through the point (2, -3). Hence, we can consider using the point-slope form:

[tex]\displaystyle y - y_1 = m(x- x_1)[/tex]

Substitute:

[tex]\displaystyle y - (-3) = -4 (x - (2))[/tex]

Simplify:

[tex]y + 3 = -4(x - 2)[/tex][tex]y = -4x + 5[/tex]

Distribute:

[tex]y + 3 = -4x +8[/tex]

And subtract:

[tex]y = -4x + 5[/tex]

In conclusion, our equation is:

[tex]y = -4x + 5[/tex]
