-5x=9

÷-5

x=1.8

Step-by-step explanation:

Answer:

x = -2.6

or x=-2 and 3/5

Step-by-step explanation:

Simplifying

11 = -5x + -2

Reorder the terms:

11 = -2 + -5x

Solving

11 = -2 + -5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '5x' to each side of the equation.

11 + 5x = -2 + -5x + 5x

Combine like terms: -5x + 5x = 0

11 + 5x = -2 + 0

11 + 5x = -2

Add '-11' to each side of the equation.

11 + -11 + 5x = -2 + -11

Combine like terms: 11 + -11 = 0

0 + 5x = -2 + -11

5x = -2 + -11

Combine like terms: -2 + -11 = -13

5x = -13

Divide each side by '5'.

x = -2.6

Simplifying

x = -2.6

Answer:

The answer is

→ [tex]-4 \frac{4}{35}[/tex]

Step-by-step explanation:

[tex]3\frac{2}{7} - 7\frac{6}{15}[/tex]

[tex]=\frac{23}{7} - 7\frac{6}{15}[/tex]

[tex]=\frac{23}{7} - 7\frac{2}{5}[/tex]

[tex]=\frac{23}{7} - 7\frac{37}{5}[/tex]

[tex]=\frac{-144}{35}[/tex]

[tex]=-4 \frac{4}{35}[/tex]

Therefore, [tex]-4 \frac{4}{35}[/tex] is your answer.

Answer:

Step-by-step explanation:

Find two linear functions p(x) and q(x) such that (p (f(q(x)))) (x) = x^2 for any x is a member of R?

Let  p(x)=kpx+dp  and  q(x)=kqx+dq  than

f(q(x))=−2(kqx+dq)2+3(kqx+dq)−7=−2(kqx)2−4kqx−2d2q+3kqx+3dq−7=−2(kqx)2−kqx−2d2q+3dq−7  

p(f(q(x))=−2kp(kqx)2−kpkqx−2kpd2p+3kpdq−7  

(p(f(q(x)))(x)=−2kpk2qx3−kpkqx2−x(2kpd2p−3kpdq+7)  

So you want:

−2kpk2q=0  

and

kpkq=−1  

and

2kpd2p−3kpdq+7=0  

Now I amfraid this doesn’t work as  −2kpk2q=0  that either  kp  or  kq  is zero but than their product can’t be anything but  0  not  −1 .

Answer: there are no such linear functions.

Task

Here are the low temperatures (in Celsius) for one week in Juneau, Alaska:

Monday Tuesday Wednesday Thursday Friday Saturday Sunday

5 -1 -6 -2 3 7 0

Arrange them in order from coldest to warmest temperature.

On a winter day, the low temperature in Anchorage was 23 degrees below zero (in ∘C ) and the low temperature in Minneapolis was 14 degrees below zero (in ∘C ). Sophia wrote,

Minneapolis was colder because −14<−23.

Is Sophia correct? Explain your answer.

The lowest temperature ever recorded on earth was −89∘C in Antarctica. The average temperature on Mars is about −55∘C. Which is warmer, the coldest temperature on earth or the average temperature on Mars? Write an inequality to support your answer.

IM Commentary

The purpose of the task is for students to compare signed numbers in a real-world context. It could be used for either assessment or instruction if the teacher were to use it to generate classroom discussion.

Solution

Let’s begin by plotting them all on the same number line.

Sol_2_ec6fb38ef3896587f51b9afceb07f705

The number line has positive numbers to the right of zero and negative numbers to the left of zero. This means that numbers farther to the right are always greater than those to the left. In terms of temperature, the coldest temperature (the least number) is all the way to the left, and the warmest temperature (the greatest number) is all the way to the right.

We can now list the temperatures from coldest to warmest:

−7,−6,−2,−1,0,3,5

Sophia is incorrect. It is common for students to compare negative numbers as if they were positive and to assume that the one with the greatest magnitude is the greatest number. However, −23 is to the left of −14 on the number line, and so it is less than −14. Thus

−23<−14

and Anchorage was colder.

Again, the coldest temperature corresponds to the least number. So the warmest temperature corresponds to the greatest number. Since

−55>−89

the average temperature on Mars is warmer than the coldest temperature on Earth.

Answer:

3500

Step-by-step explanation:

To find a fraction of something just keep in mind that "of" means to multiply (when dealing with fractions and percents).  In this case we want to know what 5/6 of 4200 is.  So do (5/6)*4200 and that equal 3500.

Step-by-step explanation:

consecutive means that they come after each other

17+16+15=48

Answer:

Use the translation formula to determine the new points.

A' → ( 5 + 4, -8 + 2) = ( 9, -6 )

B' →  ( 1 + 4, -1 +2) = ( 5, -1 )

C' →  ( -7 + 4, -3 + 2 ) = ( 3, -1 )

A' = (9, -6)

B' = (5, 1)

C' = (-3, -1)

Answer:

Total hours worked = 21

Total earned = 15gg + 16nn

Step-by-step explanation:

We know:

Grocery store: $15/hour

Nursery: $16/hour

Total hours worked = 12 + 9 = 21

Your expression would be:

Total earned = 15gg + 16nn

Answer:

[tex]y = \frac{10x - 1}{45} \\ [/tex]

Step-by-step explanation:

[tex] \frac{10x - 1}{3y} = 15 \\ 10x - 1 = 15 \times 3y \\ 10x - 1 = 45y \\ \frac{10x - 1}{45} = y \\ [/tex]

Since y is inversely proportional to [tex]x^2[/tex], the value of y, when x = 10 is 4.

Given the following data:

To find the value of y, when x = 10:

Mathematically, translating the inverse relationship between x and y, we have:

[tex]y \;\alpha\; \frac{1}{x^2} \\\\y \;= \frac{k}{x^2}[/tex]

Substituting the given parameters into the formula, we have;

[tex]16 = \frac{k}{5^2} \\\\k = 16 \times 25[/tex]

k = 400

Now, we can find the value of y, when x = 10:

[tex]y = \frac{400}{10^2} \\\\y = \frac{400}{100}[/tex]

y = 4

Answer:

The x-intercept of the function is 4 which represents the total time of the trip, in hours.

Step-by-step explanation:

Since Skylar was a distance of 0 miles from City A after 4 hours, the x-intercept of 4 represents how many hours it took Skylar to drive from her house to City A.

Have a good day :)

The x- intercept is 4 hours.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δxwhere,m is the slope

Given:

D=120-30t.

According to slope - intercept form

y= mx+ b

where m is the slope and b is the y intercept.

So,  the x-intercept

0= 120- 30t

t= -120/ (-30)

t= 4

Hence, the x- intercept is 4 hours.
