What is an equation of the line that passes through the point (-5,-4) and is perpendicular to the line 5x+6y=36

Answer:

45 minutes.

Step-by-step explanation:

Yesterday, he made 6 keychains in 30 minutes.

Hugo wants to make 9 keychains today. We need to find how long will it take him to make the keychains.

6 keychains = 30 minutes

1 keychains = (30/6) minutes

For 9 keychains,

[tex]9\ \text{keychains}=\dfrac{30}{6}\times 9\\\\=45\ \text{minutes}[/tex]

So, to make 9 keychains, it will take 45 minutes.

Answer:

-xy+y

Step-by-step explanation:

=2xy-3xy+y

=-xy+y

Answer: The answer is 16y I think

Step-by-step explanation:

This is quite simple. Toby ran 5 units, and it says Kate ran 4 times Toby ran meaning the person ran [tex]4 * 5[/tex] so 20 units. Then it says Jim ran 3 times the units Kate ran. Meaning it would be [tex]3 * 20[/tex] which is 60 units. Hence Jim ran 60 units or 60 miles. :D

Answer:

She was wrong in her analysis because the sales discount of 25% is the discount on the original cost of the dress and not the purchasing cost of the dress as explained below:

Step-by-step explanation:

From the question:

Purchasing cost price of the dress = £30

However, this cost (£30) was after a 25% Sales Discount        

It, therefore, implies that £30 is equal to 75% of the cost price

75% of the original cost price  = £30

100% of the original cost price = (30 x100%)/75%

   Original cost price                 = £40

Therefore the 25% discount / savings on the cost

                                                     = £ (40-30)

                                                      = £10    

She saved £10 by buying the dress at £30 instead of the original cost of £40                                        

Answer: $12.61

Step-by-step explanation:

Given : Total cost of meal for 5 people = $52.95

Jenna ordered a dessert for $2.50.

Total cost other 4 need to pay = $ (52.95- 2.50) = $ 50.45

Now , each person will pay [tex]=\$\dfrac{50.45}{4}\approx \$12.61[/tex]

Hence, each of the other person need to pay $12.61 .

Answer:

The ratio of salmon to total fish caught is 9 over 25.

Step-by-step explanation:

Start with what we know. We have 200 total fish caught and 36% are salmon. The rest is just mumble jumble so don't pay attention to that.

All we have to do is find 36% of 200, and the easiest way to do that is by first knowing that 36% of 100 is 36 so if we double that it will give us 36% of 200.

36 x 2 = 72

So, the ratio of salmon to total fish caught is 72 over 200. But, in simplest form is 9 over 25 because 72/200 divided by 4/4 = 9/25.

4g=24

Step-by-step explanation:

so we have 16=4(9-x) we calculate this equation

16=(4*9)_x*4

so 16=36-4x

wich means these 2 equations are equivalent

Answer:

2 2/9

Step-by-step explanation:

2 divided by 9/10 = 2/1 / 9/10

2/1 x 10/9 = 20/9 = 2 2/9 or 2.222..

Answer:

2.4 cm

Step-by-step explanation:

[tex] \frac{6}{15} = \frac{x}{6} \\ \\ 15x = 6 \times 6 \\ \\ 15x = 36 \\ \\ x = \frac{36}{15} \\ \\ x = 2.4[/tex]

Use the formula P = 2a+ b.

Let a = 12

Let b = 8

P = 2(12) + 8

P = 24 + 8

P = 32

Answer:

option A

Step-by-step explanation:

Answer/Step-by-sep explanation:

1. Given:

∆NMK ≅ ∆TRP

[tex] \overline{NM} = 20 [/tex]

[tex] \overline{MK} = 15 [/tex]

[tex] \overline{KN} = 25 [/tex]

[tex] \overline{TR} = 3x - 1 [/tex]

a. To complete the congruent statement, thus: ∆MNK ≅ ∆RTP

b. The side that is congruent to [tex] \overline{TR} [/tex] is [tex] \overline{NM} [/tex]. Thus:

[tex] \overline{TR} [/tex] ≅ [tex] \overline{NM} [/tex]

c. Since [tex] \overline{TR} [/tex] ≅ [tex] \overline{NM} [/tex], therefore:

[tex] \overline{TR} = \overline{NM} [/tex]

[tex] 3x - 1 = 20 [/tex] (substitution)

Add 1 to both sides

[tex] 3x = 20 + 1 [/tex]

[tex] 3x = 21 [/tex]

Divide both sides by 3

[tex] x = \frac{21}{3} [/tex]

[tex] x = 7 [/tex]

2. a. Slope of LK = [tex] \frac{rise}{run} = \frac{4}{3} [/tex]

Slope of LM = [tex] \frac{rise}{run} = -\frac{3}{5} [/tex]

b. ✍️Length of LK is the distance between L(-7, 4) and (-4, 8):

[tex] Lk = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

[tex] Lk = \sqrt{(-4 -(-7))^2 + (8 - 4)^2} [/tex]

[tex] Lk = \sqrt{(3)^2 + (4)^2} [/tex]

[tex] Lk = \sqrt{9 + 16} [/tex]

[tex] Lk = \sqrt{25} [/tex]

[tex] Lk = 5 [/tex]

✍️Length of LM is the distance between L(-7, 4) and (-2, 1):

[tex] LM = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

[tex] LM = \sqrt{(-2 -(-7))^2 + (1 - 4)^2} [/tex]

[tex] LM = \sqrt{(5)^2 + (-3)^2} [/tex]

[tex] LM = \sqrt{25 + 9} [/tex]

[tex] LM = \sqrt{34} [/tex]

[tex] LM = 5.8 [/tex] (nearest tenth)

∆KLM is not an isosceles ∆ because it does not has two equal side lengths. This we can see because LK and LM are not equal.

Therefore, Anthony is incorrect. Am isosceles ∆ has two equal sides.

Answer:

32 percent

Step-by-step explanation:

32 plus 68 =100

32 divided by 100 equals .32 or 32 percent

Answer:

Your answer is C, 32%

Step-by-step explanation:

It is 32% because if there is 32 shaded and 68 unshaded you would count the ones that are shaded which would be 32%.

Answer:  [tex]y=-\dfrac67x-\dfrac{34}{7}[/tex]

Step-by-step explanation:

Slope-intercept form: y=mx+c   (i) , of linear equations,  m= slope and c= y-intercept of the line.

6x+7y=13in slope intercept form would be :

[tex]7y=13-6x\\\\\Rightarrow\ y=\dfrac{-6}{7}x+\dfrac{13}{7}[/tex]

Comparing to (i) , [tex]m = \dfrac{-6}{7}[/tex]

Slope of parallel lines are equal.

So, slope of required line = [tex]m = \dfrac{-6}{7}[/tex]

Equation of line with slope m and passes through point : [tex](y-b)=m(x-a)[/tex]

So, equation of required line:

[tex](y-(-4))=\dfrac{-6}{7}(x-(-1))\\\\\Rightarrow\ (y+4)=\dfrac{-6}{7}(x+1)\\\\\Rightarrow\ y+4=\dfrac{-6}{7}x-\dfrac{6}{7}\\\\\Rightarrow\ y=-\dfrac67x-\dfrac{6}{7}-4\\\\\Rightarrow\ y=-\dfrac67x-\dfrac{34}{7}[/tex]

Answer: only 2 (y = -1/2x - 3)

Step-by-step explanation: so first find the gradient by doing y minus x and dividing

-4-0/2--6 which equals -1/2 so you know that -1/2 is your gradient. 2 is the only one with a gradient of -1/2x.

Answer:

The square root of 64 is 8

8 x 8 = 64

Answer: x = 160

Step-by-step explanation:

540 = 100+(x-25)+(x-15)+(1/2)x+(1/2)x

540= 100-40+3x = 60+3x

480 = 3x

x = 160

Answer:

0.5x + 0.5x + (x-25) + (x-15) + 100 = 540

x + x - 25 + x - 15 + 100 = 540

3x + 60 = 540

3x = 540 - 60

3x = 480

x = 480/3

x = 160

Answer:

r = 11

Step-by-step explanation:

Is the question

r - 4 = - 3 + 10

So what's r

r - 4 = -3 + 10      Combine the right

r - 4 =  7              Add 4 to both sides

r - 4 + 4 = 7 + 4

r = 11

Answer:

wait look it up on google

Step-by-step explanation:

Answer:

If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.
