solution for class 7

Step-by-step explanation:

the total distance traveled would be 15

Answer:

10-x

Step-by-step explanation:

The total amount is made up of movies and music

total =  movies + music

10 = x+ music

Subtract x from each side

10-x = x+music-x

10-x = music

Answer:

the answer is 10-x

Answer:

f(-2) + 9 is 19

Step-by-step explanation:

[tex]f(x) = - 3x - 2[/tex]

when x is -9:

[tex]f( - 2) = - 3( - 2) - 2 \\ f( - 2) = 10[/tex]

sum up with 9, f(-2)+9:

[tex]f( - 2) + 9 = 10 + 9 \\ = 19[/tex]

Answer:

3-5: 3+(-5) and -5+3

5-3: 5+(-3) and -3+5

Step-by-step explanation:

3+(-5) is 3 plus -5 which is simplified into 3-5

-5+3 can be rearranged to make 3-5

5+(-3) is 5 plus -3 which is simplified into 5-3

-3+5 can be rearranged to make 5-3

Answer:

Yes and domain is R

Step-by-step explanation:

f(g(x)) = f((2x+1)/x) = 1/(((2x+1)/x)-2) = 1/(2x+1-2x)/x = x. Yes they are inverse of each other. The domain of the composition is the whole R

Answer:

2/12 is not a reasonable answer for the fraction of his book Min has read. The fraction should be closer to 1/2.

Step-by-step explanation:

First, find common denominators. Note that what you do to the denominator, you must do to the numerator:

1/8

1/4 x (2/2) = 2/8

1/8 + 2/8 = 3/8

Find common denominators between the amount he read as well as the amount he thinks he read:

(3/8)(3/3) = 9/24

(2/12)(2/2) = 4/24

Min has read 9/24 of his book, while he states that he read 4/24 of his book.

2/12 is not a reasonable answer for the fraction of his book Min has read. The fraction should be closer to 1/2.

Note: 9 is only 3 parts away from 12 (12/24), while 9 is 5 parts away from 4 (4/24).

Answer: i think its b

Step-by-step explanation:

Answer:

-5g(4) - 1 is 9

Step-by-step explanation:

[tex]g(x) = 1 - \frac{3}{4} x[/tex]

when x is 4:

[tex]g(4) = 1 - \frac{3}{4} \times 4 \\ = 1 - 3 \\ = - 2[/tex]

therefore:

[tex] - 5g(4) - 1 = - 5( - 2) - 1 \\ = 10 - 1 \\ = 9[/tex]

Answer:

9

Step-by-step explanation:

g(x) = 1 - ¾ x

-5g(4) - 1

First find g(4) = 1 - 3/4(4) = 1 - 3 = -2

Then -5(-2) -1 = 10 -1 = 9

The solution of given equation is 5.04.

To find the solution of given equation.

A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.

Given that:

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

4 1/5 ÷ 1 1/5 = 11 - 1 7/18x

convert into simple fraction form, we get

21/5 ÷ 11/5=11-17x/18

convert  divide into multiply

21/5*5/11=11-17x/18

cancel out 5 from numerator and denominator, we get

21/11=11-17x/18

same form are in same side

17x/18=11-21/11

after simply, we get

17x/18=121-21/11

17x/18=100/21

cross multiplication on both sides and find x,we get

x=100*18/21*17

x=5.04

So, the solution of given equation is 5.04.

Answer:

(10,0)(-1,0)

Step-by-step explanation:

x^2 - 9x - 10 = 0

(x - 10)(x + 1) = 0

The two solutions are

x - 10 = 0

x = 10

or

x+1 = 0

x = - 1

Answer:

x=10, x=-1

Step-by-step explanation:

Hi there!

We are given this equation:

x²-10=9x

And we want to solve it by factoring

Factoring is easier to do when all of the terms are on the same side, so let's subtract 9x from both sides

x²-9x-10=0

Now we must think of two numbers that add up to -9, but multiply to get -10

Those numbers are -10 and 1

So factor the polynomial using FOIL:

(x-10)(x+1)=0

Now split and solve via the zero product property:

x-10=0

Add 10 to both sides

x=10

x+1=0

Subtract 1 from both sides

x=-1

Hope this helps!

Answer: just read

Step-by-step explanation:

So first you plot the points, then calculate how many units it takes from the point that is Sean’s house to his School. Show your work on that by drawing out your skip counting. Then you plot the rest of the points and fpro this calculation: the distance from Sean’s house to his school+ from his school to the grocery store. Then you calculate the distance (in units! ! ! Which means one box is one unit) : distance from Sean’s house to the school+ from school to the commmunity center. Then two calculations you made above you compare. So whichever one is greater is your answer for part b.
