If f(x) = x + 7 and g(x) - what is (fºg)(x)?
0 4.

Answer:

x +3 = y

Step-by-step explanation:

So you are looking for mx + b = y

m is the slope

b is the initial value

Try to isolate the y variable

x - y = -3

Subtract x from both sides

-y = -x - 3

Multiply everything by -1 to make the y value positive

y = x + 3

Answer:

12.2

Step-by-step explanation:

Let C be the last angle c + 55° + 35° = 180° (sum of angles in a triangle)

C + 90° = 180°

C = 180° - 90°

C = 90°

Let c be the last side

Using the sine rule a/sinA = b/sinB = c/sinC

Using any of the other two sides,

10/sin55° = c/sin90°

c = 10/sin55° × sin90°

c = 10/0.8192 × 1

c = 12.21

c ≅ 12.2

Answer:

40 km/hr

Step-by-step explanation:

Given that:

Total distance covered in 3 hours = 60km

Speed during first 40 km = 16km/hr

Hence, time spent during the first 40 km ;

Recall:

Time = distance / speed

Time = 40 / 16

Time = 2.5 hours

Hence, speed required to cover the remaining (60 - 40) = 20km in (3 - 2.5) hours =0.5 hours

Speed = distance / time

Speed = 20 / 0. 5

Speed = 40 km / hr

Answer:

21°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

subtract the sum of the 2 given angles from 180 for the other angle

other angle = 180° - (90 + 69)° = 180° - 159° = 21°

Answer:

[tex]-6x+ 3.2[/tex]

Step-by-step explanation:

Given the expression

step one: let us work on the terms inside the bracket

[tex]3x (-2) + 3.2[/tex]

Step two:

open the bracket

[tex]-6x+ 3.2[/tex]

Hence the simplified expression is

2) 7+8=15   This would be a single line, not a triangle.

3) 3+8<15   This would be a single line, not a triangle.

2) 15+8=23   This would be a single line, not a triangle.

She would get back 10.05

Step-by-step explanation:

Do 9.99 times three and you get 29.97 then do 14.99 times two and you get 29.98 then add them together to get 59.95. Next subtract 70.00 from 59.95 then you get how much change she needs back

Answer:

-17/-1 and 17 are the same so you are correct!

Step-by-step explanation:

in the fraction, -17/-1, you want to get rid of the negatives. in order to do that, you have to get rid of them on both the numerator and denominator! so the new fraction would be 17/1, and that would be simplified to just 17! so you are correct, i hope this helps!

Answer:

yes your cauculators correct, it is 17

Step-by-step explanation:

you need to divide the fraction since there are 2 negative numbers

Answer:

Well, the y axis is the up and down line of the graph. Therefore, if the translation says move up six, simply add six to the y axis (ex. -6, -10 move up six: -6, -4)! super simple, right? hope this helps!

Answer:

The radius of sphere with volume 4500 cubic inches is 10.24 inches.

Step-by-step explanation:

Let V be the volume of the sphere

Given

Volume of sphere = V = 4500 cubic inches

Let r be the radius of the sphere

The volume of the sphere is given by the formula

[tex]V = \frac{4}{3}\pi r^3[/tex]

Putting the known values

[tex]4500 = \frac{4}{3} * \frac{22}{7} * r^3\\4500 = \frac{88}{21} * r^3\\r^3 = \frac{21}{88} * 4500\\r^3 = 1073.8636[/tex]

Taking cube root on both sides

[tex]\sqrt[3]{r^3} = \sqrt[3]{1073.8636} \\r = 10.2403[/tex]

Rounding off to nearest hundredth

The radius is: 10.24 inches.

Hence,

The radius of sphere with volume 4500 cubic inches is 10.24 inches.

Step-by-step explanation:

y = mx + c

8 - 7x = 4y

4y = 8 - 7x

y = (8 - 7x)/4

= 2 - 7/4x

y = -7/4x + 2

Slope = m = -7/4

Answer:

slope = - [tex]\frac{7}{4}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

8 - 7x = 4y, that is

4y = - 7x + 8 ( divide all terms by 4 )

y = - [tex]\frac{7}{4}[/tex] x + 2 ← in slope- intercept form

with slope m = - [tex]\frac{7}{4}[/tex]

Answer:

a rhombus that is the answer

The best describes the figure that is represented by the following coordinates A(-4, 3), B (2,3), (3, -1), and D(-5, -1) will be a rhombus.

Its a parallelogram but all sides of the same length.

A rhombus is a parallelogram whose all sides are of equal lengths.

Its diagonals are perpendicular to each other and they cut each other in half( thus, they're perpendicular bisector of each other).

Its vertex angles are bisected by its diagonals.

The triangles on either side of the diagonals are isosceles and congruent.
