Answer:

2/3

Step-by-step explanation:

Firstly we get the y value at both x points

At x = 1

y = 2/3 + 1/2 = (4 + 3)/6 = 7/6

At x = 2

y = 4/3 + 1/2 = (8 + 3)/6 = 11/6

The slope formula is

m = (change in y)/change in x

The slope is thus;

(11/6-7/6)/(2-1) = 4/6 = 2/3

have a good day or night

Answer:6 + 12² = x

Hope it helps! Have a great day!

A numerical expression to represent the phrase the sum of 6 and the square of 12 is,  P = 6 + 12²

An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.

For example, 2x+3

Given information,

We have to make numerical expression  of,

sum of 6 and the square of 12

Suppose expression value is P

Then, P = 6 + 12²

Therefore, The desired result is  P = 6 + 12²

Answer:

This week her gross wage is equal to $216.25

Step-by-step explanation:

From the question it self we can make the following equation.

Let  "W" be the gross wage for the week.

Let  "V" be the value of the goods she sells.

then.....

W = $140 + 0.05V

(Where $140 is the price she will be paid for just working and 0.05V is the commission she will get paid this week)

Now that we know what "v" equal to, we can easily find out her Gross Wage this week by inserting in the value of V. And so we get.......

W = $140 + 0.05V

W = $140 + 0.05 x 1525

W = $140 + 76.25

W = $216.25

Answer:

The value of a is 25

Step-by-step explanation:

When two angles are supplementary, they add up to 180 degrees

Mathematically,

(30 + 2a) + (125-a) = 180

30 + 2a + 125 - a = 180

a + 155 = 180

a = 180-155

a = 25 degrees

Answer:

Step-by-step explanation:

rise/run = 4/7

since were coming from the origin this is easy

since the y is 4 we know the rise is 4

since the x is 7 we know the run is 7

y = 4/7x

hope this helps <3

Answer:

since all sides are congruent the you could divide 180 by the because there are 180 degrees in a triangle

So the measure of angle R is 60 degrees

Answer:

you combine like term

-8.5+7.9

Step-by-step explanation:

Answer:

B; 4/d-6

Step-by-step explanation:

We want to perform a division here

Flipping the right hand side while changing the sign to multiplication, we have that;

(2d - 6)/ (d^2 + 2d -48) * (2d + 16)/d-3

= 2(d-3)/(d^2 + 2d - 48) * 2d + 16/d-3

= 2/(d^2 + 2d - 48) * 2d + 16/1

2/(d-6)(d + 8) * 2(d + 8)/1

= 2/d-6 * 2/1

= 4/d-6

Answer:

RS = XY (since the two a triangles are similar, you have to match the sides up and then set the values equal to eachother to find the value of x)

3x +2 = 5x -3 (subtract 5x from both sides)

-2x +2 = -3 (subtract 2 from both sides)

-2x = -5 (divide both sides by -2 to isolate x)

x = 2.5 (take the value of x and plug it into the expression given for RS)

3(2.5) +2 (multiply)

7.5 +2 (add)

9.5 (this is the length of RS)

Answer:

Kayla is correct

Step-by-step explanation:

For a vertical line, the x-value is the same

This means there is no change in the x value

A slope is calculated by dividing by the change in x value

since in this case , we will be dividing by zero, it means that the value of our slope is going to be undefined

This means that Kayla is correct

[tex]\Large\boxed{\tt Answer:~Isosceles~Triangle;~x=25}[/tex]

[tex]\tt Step-by-step~explanation:[/tex]

Since this triangle has two congruent angles/sides, we know that it is an isosceles. We can tell by looking at the markings on the triangles: The curves on both angles A and C indicate that they are congruent, and the markings on lines AB and CB also tell us that they are congruent.

To solve for x, we set up our equation like this:

[tex]\tt 4x-20=2x+30[/tex]

Since we know that lines AB and CB are congruent, that means 4x - 20 is equal to 2x + 30.

To solve, we can first subtract 2x from both sides and add 20 to both sides.

[tex]\tt 4x-(2x) -20=2x-(2x)+30\\2x-20+(20)=30+(20)\\2x=50[/tex]

Then, we divide both sides by 2 to isolate x.

[tex]\tt \frac{2x}{2} \frac{50}{2} \\x=25[/tex]

We can check if our answer is correct by plugging in our value for x into both expressions and see if they equal the same thing.

[tex]\tt 4(25)-20=80\\2(25)+30=80\\Correct[/tex]

Answer:

Percentage of boy students is 45 per cent.

The total number of students is 480.

Step-by-step explanation:

To find the percentage of boy students, just subtract 55% (the percentage of girl students) from 100%, then you'll get 45%.

To find the total number of students, just use algebraic equation, rearrange it, and solve for x.

The workings are shown in the picture attached. Hope this helps!

Answer:

total of students is 480

Step-by-step explanation

let t = total of students.

if 55% of the students in school are girls.

then 45% of the students in the school are boys.

if there are 216 boys in school.

[tex]45\% \times t = 216 \\ t = \frac{216}{45\%} \\ t = \frac{216}{ \frac{45}{100} } \\ t = \frac{216 \times 100}{45} \\ t = 480[/tex]
