Answer:

not sure if that is the Answers

The equation of a line is y = mx where m is the slope. That line passes through the origin. If you want it to pass through some point (a, b) you subtract the coordinates like this: y - b = m (x - a). That is the point-slope form, and you can rewrite it in other forms if it is convenient. You may do this with any point on the line.

Answer:

Jeffrey's pickup truck will be able to carry 55 square feet of granite.

Step-by-step explanation:

There are 2000 pounds in 1 Ton

Jeffrey's pickup truck bed can safely hold half a ton of weight.

So that means his pickup truck can hold

2000/2 = 1000 pounds

He also plans to pick up a 120-pound kitchen sink in the same trip.

So the remaining weight limit is

1000 - 120 = 880 pounds

Since the granite weighs 16 pounds per square foot

880/16 = 55 sq ft.

Therefore, Jeffrey's pickup truck will be able to carry 55 square feet of granite.

The question is not very clear, but I am assuming that you are asking how to get from 30/8 to 3 6/8

This is a mere simplification problem. We have simplified 30/8 into 3 6/8.

To start, let's check out the multiples of 8 that are less than 30

8, 16, 24. We want the largest multiple, 24. here we have

[tex]\frac{24}{8} + \frac{6}{8}[/tex]

Simplify 24/8 into 3.

Now you're done!

Answer:

look below

Step-by-step explanation:

first distribute 3/4 into (x-8)= 3/4x-6

3/4x-6=12

then add 6 to both sides to get rid of -6

3/4x=18

Now multiply 4 times 18 to get rid of division (72)

now you are left with 3x=72, so you now divide by 3 and you get x=24

Answer:

The correct answer is C

Answer: x = 2

Step-by-step explanation:

Answer:

x = ± 2

Step-by-step explanation:

Given

(x² + 4)² - 11(x² + 4) + 24 = 0

Use the substitution

u = x² + 4, then

u² - 11u + 24 = 0 ← in standard form

(u - 3)(u - 8) = 0

Equate each factor to zero and solve for u

u - 3 = 0 ⇒ u = 3

u - 8 = 0 ⇒ u = 8

Change u back into terms of x

x² + 4 = 8 ( subtract 4 from both sides )

x² = 4 ( take the square root of both sides )

x = ± [tex]\sqrt{4}[/tex] = ± 2

One value of x tat is a solution is x = 2

Answer:

[tex]a = \frac{5}{2}b[/tex]  

Step-by-step explanation:

6a - 4b = 6b + 2a

Combine like terms:

6a - 2a - 4b = 6b (Subtract '2a' from both sides)

4a = 6b + 4b (Add '4b' to both sides)

4a = 10b

[tex]a = \frac{5}{2}b[/tex]   (Divide both sides by 4)

Therefore, when simplified, [tex]a = \frac{5}{2}b[/tex].

Answer:

(7 a - 8y^2) x (3-y)

Step-by-step explanation:

21a+8xy^3 −24y^2−7axy

factor out 3 from the expression

3( 7 a - 8 y^2) + 8y^3 - 7 a y

3(7 a - 8 y^2) - y x (-8y^2 + 7 a)

Factor out 7 a - 8y^2 from the expression

(7 a - 8y^2) x (3-y)

= (7 a - 8y^2) x (3-y)

Answer:

17

Step-by-step explanation:

Based on the 2nd equation, it seems that x=-3-3y.  I got that by subtracting both sides by 6y and then dividing both sides by 2.  Now  substitute that in place of x in the first equation.  (-3-3y)/3-2y=14.  Simplify that and get               -1-y-2y=14.  Add 1 to both sides and simplify.  You get -3y=15.  Divide both sides by -3 and get y=-5.  Now substitute -5 into the equation for x. x=-3-3(-5)

x=-3+15=12

So x=12 and y=-5.  Now do 12-(-5)=12+5=17

Answer:

45

Step-by-step explanation:

The total amount of oranges and apples in the box are 54.

54/(1+5)

54/6

= 9

Oranges to apples is in the ratio 1:5

1×9 : 5×9

9 : 45

The number of oranges in the box are 9.

The number of apples in the box are 45.

Answer:

45 apples and 9 oranges

Step-by-step explanation:

Total = 54

Ratio = 1:5

Total Parts = 1+5 = 6

Oranges:

=> [tex]\frac{1}{6} * 54[/tex]

=> 1*9

=> 9 oranges

Apples:

=> [tex]\frac{5}{6} * 54[/tex]

=> 5*9

=> 45 apples

Answer:

1 : 9

Step-by-step explanation:

Given 2 similar figures with sides in ratio a : b , then

ratio of areas = a² : b²

Here the ratio of sides = 1 : 3 , thus

ratio of areas = 1² : 3² = 1 : 9

The ratio of the areas of the similar triangles is 1 : 9

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be represented as ΔABC

Let the second triangle be represented as ΔDEF

And , they are similar triangles

Now , the sides of one are three times as long as the sides of the other

Let's call the sides of the smaller triangle a, b, and c, and the sides of the larger triangle 3a, 3b, and 3c. Then we know that:

a : 3a = b : 3b = c : 3c

Simplifying this, we get:

1 : 3 = 1 : 3 = 1 : 3

This means that the corresponding sides of the two triangles are in a ratio of 1:3

Now, let's use the formula for the area of a triangle:

A = ( 1/2 ) x base x height

The base and height of the two triangles are also in a ratio of 1:3, so the ratio of their areas is:

(1/2) x 1 x 1 : (1/2) x 3 x 3

So , the ratio is 1 : 9

Hence , the ratio of the areas of the smaller triangle to the larger triangle is given by 1 : 9

Answer:

f(x) = x^2 - 2x + 12

Step-by-step explanation:

the f(x) equation has a y-intercept of 12 because f(x)=x^2 - 2x has a y-intercept of 0 and the + 12 at the end shifts the function up 12 units putting the y-intercept at (0,12) while on the graph of the function g(x) it intercepts the y-axis at (0,1).

Step-by-step explanation:

Let y = -A cos B(t -c) + D

A, amplitude = 20ft

Period = 2π / B ( B = π / 15)
