An expression is a collection of variables and constants that are bound by some mathematical operation the value for w for the given expression w -5.36=10+w/6 is 18.432.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

As per the given expression,

w - 5.36 = 10 + w/6

Subtract w/6 both sides,

w - w/6 - 5.36 = 10 + w/6 - w/6

5w/6 = 10 + 5.36

w = 18.432

Hence "The value for w for the given expression w -5.36=10+w/6 is 18.432".

Line's equation is y=(1/5)x + 2.

In elementary geometry, two geometrical objects are perpendicular if they intersect at a right angle. The condition of perpendicularity can be graphically represented using the perpendicular symbol,. Any pair of lines, any pair of planes, or any pair of lines and planes can be used to define it.

The arrow

In slope-intercept form, y=-5x12

y=mx+b

where the slope m is.

Thus, the slope of this line is

m= -5

Slopes on perpendicular lines are reciprocally negative. In other words, modify the sign by taking the slope's reciprocal.

The reciprocal of (-5) in the negative is 1/5.

Plug in the point to determine b in the formula y = (1/5)x + b.

4 = (1/5)(10) + b

4 = 2 + b

b = 2

The perpendicular line passing through the indicated point is y= (1/5)x + 2.

Thus, the equation of the line that is perpendicular to the line y = -5x - 12 and passes through the point is y= (1/5)x + 2.

Answer:

First one is 92

Step-by-step explanation:

Answer:

1. 9/2

2. 7 3/13

3. 3 13/15

4. 3 25/27

5. 2 1/4

6. 3 30/91

7. 2 5/21

8. 6 3/5

Step-by-step explanation:

When I put it like 2 5/21 I mean it's a mixed number.

Now I'll tell you the steps.

1. Find the common denominator (The denominator is the bottom number of the fraction. To find it you have to write out the multiplies of each number and once a number is the same that's the common denominator.)

2. Multiply the numerator by the amount of times it took to find the common denominator. (The numerator is the top number of the fraction. And the amount of times you'll have to multiply the numerator depends. I'll put an example below)

Example:

4/20 ÷ 7/2

2 goes into 20, 10 times so you have to multiply 7 by 10.

Then you'll get

70/20.

Now you can solve it.

4/20÷70/20

(I put random numbers so the answer may turn out funky this is just an example.)

3. Divide the fractions

If after one year, she received a total of $620 in interest.  The amount that she invest in each account is 2,000 amount invested at 7% , 8,000 amount invested at 6.

Let x represent the amount invested

Hence,

.07x + .06(10,000-x) =620

.07X+600-.06x = 620

Combine like terms

.01x =620-600

.01x=20

Divide both side by .01x

x=20/.01

x =2,000 amount invested at 7%

So,

10,000-2,000 = 8,000 amount invested at 6%

Check :

.07 × 2,000+.06× 8,000=620

150 + 480 = 620

620 =  620

Therefore we can conclude that $2,000 was invested at 7% and $8,000 was invested at 6%.

Considering the table of f ( x ) and graph of g ( x ), the value of the expression  [tex]\lim_{x \to 1} 2f(x)+g(x)^2[/tex] is represented by 3

The table represents the values of f ( x ). Using the table, checking the value of f ( x ) when x = 1 gives f ( x ) = 1

Using the graph, the value of g ( x ) when x = 1 is traced to give a value of -1

substituting the values of f ( x ) = 1 and g ( x ) = -1  into the equation

[tex]\lim_{x \to 1} 2f(x)+g(x)^2[/tex]

[tex]=\lim_{x \to 1} 2f(1)+g(1)^2[/tex]

ANSWER: Translation of Triangle Q to Triangle P

Horizontal shift 4 units left and Vertical shift 1 unit upward

Answer:

D. 9x² - 12x - 1

Explanation:

To find f(g(x)), we need to replace x by g(x) as follows:

f(x) = x² - 5

f(g(x)) = (g(x))² - 5

Then, g(x) is equal to -3x + 2, so replacing g(x) by (-3x + 2), we get:

f(g(x)) = (g(x))² - 5

f(g(x)) = (-3x + 2)² - 5

f(g(x)) = (-3x)² + 2(-3x)(2) + 2² - 5

f(g(x)) = 9x² - 12x + 4 - 5

f(g(x)) = 9x² - 12x - 1

Therefore, the answer is D. 9x² - 12x - 1

Out of 400 students, 120 students would pick math as their favorite subject.

Data provided to us

fav subject       students

 Math                  6

 Science             3

 English              4

Hence the total becomes 20 students

we have to calculate students whose favorite subject is math from 400 students

students with math as fav subject out of 20 students = 6

students with math as fav subject out of 400 students = (6 / 20) x 400

                                                                                          = 120 students

we can verify it as

%age of students out of 20 , who like math = 6/20 x 100

                                                                                   = 30 %

similarly, %age of students out of 400, who like math= 120/400 x 100

                                                                                        = 30 %
