Answer:

b= (2a+11)/5

Step-by-step explanation:

5x + 2y = 9

2y=9-5x

y= 9/2 - 5x/2

slope, m1= -5/2

for perpendicularity, m1 × m2 = -1

slope for QR= m2=

[tex] = - 1 \div \frac{ - 5}{2} = - 1 \times \frac{2}{ - 5} = \frac{ - 2}{ - 5} = \frac{2}{5} [/tex]

m2 is 2/5

[tex]qr = \frac{b - 3}{a - 2} [/tex]

[tex] \frac{2}{5} = \frac{b - 3}{a - 2} [/tex]

5(b-3)=2(a-2)

5b-15=2a-4

5b=2a-4+15

5b= 2a+11

[tex]b = \frac{2a + 11}{5} [/tex]

An expression for b in terms of a is b = (2a + 11)/5.

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

Given an equation of a line 5x + 2y = 9 ⇒ 2y = - 5x + 9 ⇒ y = (-5/2)x + 9/2.

So, the slope of the line parallel to QR is the slope negative reciprocal of (-5/2) which is (2/5).

We know slope m = (b - 3)/(a - 2).

∴ (2/5) = (b - 3).(a - 2).

2(a - 2) = 5(b - 3).

2a - 4 = 5b - 15.

2a + 11 = 5b.

b = (2a + 11)/5.

Answer:

The constant of proportionality is the ratio between two directly proportional quantities. It can represent a number of things such as; increase or decrease in a set of numbers, a (x,y) point on a graph, or it can just be shown in a table to show rate change.

Answer:

42

Step-by-step explanation:

in order to find y, we need to find x.

180-65-62=53

x=53

we need to subtract 53-?=11

53-42=11

y=42

Answer:

42

Step-by-step explanation:

because the triangles are congruent, we can place the angle x in CDE to solve for it. Knowing the sum of all angles in a triangle is 180, we can set up the formula below.

62 + 65 + x = 180

Additionally, because the triangles are congruent, we know that the length of CD is equal to GH, letting us set up this formula:

x - y = 11

Solving the first formula, we now know the value of x, 53.

62 + 65 + 52 = 180

Plugging that into the second formula and solving, we get 42.

53 - 42 = 11

Answer:

x = -1/12

Step-by-step explanation:

12x = -4 + 3

12x = -1

Answer: B

Step-by-step explanation:

Answer:

the answer to this question would be B

Answer:The number of text messages sent by his sister=162

Step-by-step explanation:

Step 1

The ratio of number of text messages sent by Lucas to the number of text messages sent by his sister =4 to 9= 4:9

Number of text messages sent by Lucas =72

Total ratio is given as 4+ 9= 13

Step 2

such that the total number of messages sent by Lucas and by his sister will be calculated as

Ratio of text messages sent by Lucas/  total ratio x Total messages  = Number of text messages sent by Lucas . Let X = Total number of messages  

4/13 x X = 72

X=72  x 13 / 4 =234

Therefore, The number of text messages sent by his sister= ratio of  text messages sent by his sister/ Total ratio x Total number of messages  =

9/13  X 234= 162 messages

For the first two use the formula [tex]A^2 + B^2 = C^2[/tex]

[tex]15^2 + 36^2 = C^2(unknown)[/tex]

Calculate 15 x 15 + 36 x 36 = 1521

Now its

1525 = C^2

Fins the squeare root of 1521 whitch is 39

and square c^2 as well whitch make it C^1 or simple C

This give us a final anwser of the missing side

39 = C

Second triangle

For this the formual is different since we are not finding the lenght of the hypotunus (C), we know this becauee the missing angle is met my a 90 digree angle.

Here the equasion is  C^2 - A^2 = B^2

WE will it in again

15^2 - 9^2 = B^2

Calaulate 15 x 15 - 9 x 9 = 144

Now its 144 = B^2

Again we find the square root for each side

Square root of 144 is 12

and Square root of B^2 is Simpley B

We put in togethe to find the final anwser whitch is

12 = B

For the last two it is simple

All angles of a triangle added together must always equal 180 degrees

So it the two side are 75 and 32 we add them (75+32) to get 107

Now we just subtract that amount (107) form 180 to get the third missing angle. 180 - 107 = 73  

Here the missing angle is 73

One way to know if this is correct is to add all side and see if it equaels 180

75 + 32 + 73 = 180

For the second question it seems to be exactly the same as the first in the photo so the anwser would also be 73.

Given :

▪︎This triangle is an isosceles triangle.

▪︎Measure of one of its legs = 6 inches

▪︎Measure of its equivalent leg [tex] = \tt \frac{x}{9} [/tex] inches

▪︎Measure of its base [tex] = \tt \frac{5}{2} [/tex] inches

Which means :

[tex] =\tt 6 = \frac{x}{9} [/tex]

[tex] =\tt \frac{6}{1} = \frac{x}{9} [/tex]

[tex] =\tt 6 \times 9 = x \times 1[/tex]

[tex]\hookrightarrow\color{plum}\tt 54 = x[/tex]

Let us check whether or not we have found out the correct value of x by placing 54 in the place of x :

[tex] =\tt 6 = \frac{54}{9} [/tex]

[tex] = \tt6 = 6[/tex]

Since the Left Hand Side of the equation is equivalent to the Right Hand Side of the equation, we can conclude that we have found out the correct value of x.

▪︎Therefore, the value of x = 54

Answer:

Step-by-step explanation:

volume of sphere = 4πr³/3 = 972π in³

r³ = 729 in³

r = 9 in

The value of its radius is,

⇒ r = 6.14 inches

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The volume of this sphere is 972 pi cubic inches.

Now, We know that;

Volume of sphere is,

⇒ V = 4/3πr³

⇒ 972 = 4/3 × 3.14 × r³

⇒ 972 × 3 = 12.56 × r³

⇒ r³ = 232.16

⇒ r = ∛232.16

⇒ r = 6.14 inches

Thus, The value of its radius is,

⇒ r = 6.14 inches

x= -36

Step-by-step explanation:

Step 1

from the attachment, Mai's solving is given as

1/3 (1/2x- 9) = 1/2 (x+18)

1/6x-3= 1/2x+9

1/4x-3=9

1/4x=12

x=48

Mai's error started when he subtracted wrongly 1/2 x from 1/6x which gave him 1/4 x instead of - 1/3 x.

Solving correctly, we have that

1/3(1/2x-9) = 1/2(x+18)

1/6x -3= 1/2x+ 9

taking like terms to like terms

1/6x-1/2x= 9+3

(1-3)/6x= 12

-2/6x= 12

-1/3x= 12

multiplying both sides by -3

-1/3x X -3 = 12 X -3

x= -36

Step-by-step explanation:

remove your answer

Answer:

5) Slope(m): 2

y-intercept(b): (0, 4)

6) Slope(m): -1

y-intercept (b): (0, -6)

7) Slope(m): 5

y-intercept (b): (0, 8)

8) Slope(m): 7

y-intercept (b): (0, 1/2)

Step-by-step explanation:

in order to find the slope and y-intercept you need to rewrite the equation in y=mx+b.

in 5, the equation is -2x+y=4. we need to add 2x to both sides to get y=2x+4. now you can find your slope (2) and your y-intercept point (0, 4)

in 6, the equation is x+y=6. we need to subtract x from to both sides so we get y=-x+6. you would get a slope of -1 and a y-intercept point of (0, 6)

in 7, the equation is -5x=8-y. we need to add 5x to both sides to get 0=8-y+5x. then add y to both sides so we get the equation y=5x+8. you have a slope of 5 and a y-intercept point of (0, 8)

in 8, the equation 0=1-2y+14x. we need to add 2y to both sides and we get 2y=14x+1. since we need y to stand alone we need to divide both sides by 2. now we have y=7x+1/2. the slope is 7 and the y-intercept point is (0, 1/2)

The solution are (4, 10) and (10, 12).

The phenomenon of unequal or unequal distribution of resources and opportunities among members of a given society is referred to as inequality. In different contexts and for different people, the concept of inequality may mean different things. In addition, there are distinct but interconnected economic, social, and spatial dimensions to inequality. The disjuncture between the moral ethics of equity and social justice, on the one hand, and the normative concept of "deservingness," on the other, adds complexity to debates about inequality.

Given equation of inequality for basket ball and soccer ball

y ≥ 2 + x

where  x is the number of basketballs, and y is the number of soccer balls on display,

situation says  the second number must be at least 2 more than the first number. Also, we are dealing with basket ball and soccer ball, so we won't have negative numbers (Choice E is out) or fractions (Choice B is out).

for choice A: x = 4 and y = 10 (10 is 6 more than 4)

for C: x = 14 and y = 12 (12 is 2 lee than 14 it is not correct)

for D: x= 10 and y = 12  (12 is 2 more than 10)

Hence the option A and D is correct representation for solutions.
