Answer:

4(y+2) = 3(x+4) and 4y - 3x = 4

Step-by-step explanation:

The equation of the line in point slope form is expressed as;

y - y0 = m(x-x0)

m is the slope

(x0, y0) is the point on the line

Given the equation 3x - 4y = 7

Rewrite in slope intercept form

-4y = -3x+7

y = 3/4 x - 7/4

Slope = 3/4

Slope of the required line will also be 3/4  since they are parallel lines

Substitute the slope and the point into the equation above;

y - y0 = m(x-x0)

y +2 = 3/4 (x+4)

4(y+2) = 3(x+4)

4y + 8 = 3x+12

4y - 3x = 12-8

4y - 3x = 4

Hence the required equations are 4(y+2) = 3(x+4) and 4y - 3x = 4

Explanation:

I plotted all of the given points in GeoGebra. The point M in blue is the mean point located at (8.44, 400.89)

The purple line is the regression line (aka line of best fit) which is y = 41.098x + 53.843 approximately.

Answer:

x < 3

Step-by-step explanation:

Add 77 to both sides.

3x<2+7

3x<2+7

2 Simplify  2+72+7  to  99.

3x<9

3x<9

3 Divide both sides by 33.

x<\frac{9}{3}

x<  

3  9  4

Simplify  \frac{9}{3}  

3  9 to  33.

x<3

Answer:

Step-by-step explanation:

Here you go mate

Step 1

Step-by-step explanation:

I'm not sure tho dddd

Answer:

x = [tex]\sqrt{87}[/tex]

Step-by-step explanation:

if you draw a perpendicular segment from the vertex between sides 5 and 16 to the opposite side then you have a right triangle and can use the Pythagorean Theorem,  a² + b² = c²

a = x

b = 13 (you get this from 18 - 5)

c = 16

x² + 13² = 16²

x² + 169 = 256

x² = 87

x = √87

Answer:

8 grams

Step-by-step explanation:

a triangle is half a square

Answer:

I think so!

Step-by-step explanation:

Because any Expression that has 1 or more terms is a polynomial

Answer:

D is the answer for this question

Answer:

I'm not sure if this is correct but this is how i do it.

Step-by-step explanation:

[tex] \frac{7 - 3}{13 - 5} = \frac{4}{8} \\ 4 \div 2 = 2 \: (for \: x)\\ 8 \div 2 = 4 \: (for \: y)[/tex]

I take the distance between two points first.

Then, I divide it by two to get it's half length.

Then, I take the lowest point of the two which is (3,5).

Then, I add 2 to 3 and 4 to 5 which makes it (5,9).

Again, this is how I usually do it. I hope others will also answer your question.

Answer:

where is the expression??

Answer:

1. B= 6

2. B= 3.333333333

3. B= 12

Step-by-step explanation:

1. 14/ 2 1/3 (two and one third)=6

2. 14/ 4 1/5(four and one fifth)= 3.333333333

3. 14/ 7/6 (seven sixth)= 12

Answer:

15:22.5:52.5

Step-by-step explanation:

2:3:7=2+3+7=12

90 divided by 12 is 7.5

multiply each factor by 7.5

2-15

3-22.5

7-52.5

please mark as brainliest!!<3

Answer:

15 : 22.5 : 52.5

Step-by-step explanation:

2+3+7 = 12units

To find how much kg one unit is.

90kg ÷ 12units = 7.5kg/unit

2units : 7.5 x 2 = 15kg

3units : 7.5 x 3 = 22.5kg OR 22/1/2 kg

7units : 7.5 x 7 = 52.5kg OR 52/1/2 kg

Therefore, the answer is

15 : 22.5 : 52.5

Answer: The of getting an even number in first and an odd number second is 1/4 or 0.25

Step-by-step explanation:

Given,

Total number of outcomes = 36

We have to find the probability of rolling an even number first and an odd number second.

Solution,

Firstly we will find out the possible outcomes;

(2,1)(2,3)(2,5)(4,1)(4,3)(4,5)(6,1)(6,3)(6,5)

So the total number of outcomes = 9

Now according to the formula of probability, which is;

P(E)= total number of possible outcomes/total number of outcomes

Now on putting the values, we get;

P(of getting an even number in first and an odd number second)= 9/36 = 1/4 =0.25

Hence The of getting an even number in first and an odd number second is

1/4 or 0.25.

Hope this help

Answer:

2 cm

Step-by-step explanation:

h = 14 cm

Curved surface area of a right circular cylinder = 88 cm²

2πrh = 88

[tex]2 * \frac{22}{7}*r*14=88\\\\r = \frac{88*7}{2*22*14}\\\\ r =1 \\\\r = 1 cm[/tex]

Diameter = 2 * r = 2 * 1 = 2  cm
