Answers

Answer:

x = -3

Step-by-step explanation:

The equation of any linear function is y = mx + c, where m is the gradient and c is the y-intercept

The equation of the function is y = -x + 4

The gradient is negative one (hence 1x) and the y-intercept is 4

We need to find what x equals when the y = 7

7 = -x + 4

Rearrange

7 - 4 = -x

-x = 3

x = -3

You drive to visit your parents, who live 100 miles away. Your average speed is 50 miles per hour. On arrival, you stay for five hours and then return home, again at an average speed of 50 miles per hour. Which graph depicts your distance from home from the time you leave until you return?

Answers

Answer: The first graph is the answer.

Step-by-step explanation: If your parents house is 100 hours away, and you're driving at 50 mph, then it would take 2 hours to get to you're parents house (100 ÷ 2 = 50). Then you stay at your parents house for 5 hours (2 + 5 = 7), the graph stays the same place on the y axis for 5 hours. Afterwards you drive home, same distance as when you drove to your parents (2), but you're going back so it's going down. This makes graph 1 the answer.

A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 6 1/4 °F. The submarine dives down 115 feet deeper, and the water temperature drops by 2 1/5 °F. What were the elevation and the water temperature after the submarine dove? Assume that sea level is at 0 feet of elevation. Complete the steps below to solve the problem.

Answers

Step-by-step explanation:

At the elevation 617.5 feet below the sea level temperature of the water was °F

Step-by-step explanation:

At 502.5 feet below the sea level temperature of the water is °F

When submarine dives down 115 feet deeper, water temperature drops by °F

Elevation after the submarine dove = -502.5 - 115 = -617.5 feet

This negative sign represents the elevation below the sea level.

And the temperature will be = 

                                               = 

                                               = 

                                               = 

                                               = °F

Therefore, at the elevation 617.5 feet below the sea level temperature of the water was °F

4(2x - 5) -6( ) = 6+9) + (2x - 5)

Answers

Answer: x=6

Step-by-step explanation:

Step 1: Remove parentheses.

4(2x-5)-6=6+9+2x-54(2x−5)−6=6+9+2x−5

Step 2: Simplify  6+9+2x-56+9+2x−5  to  2x+102x+10.

4(2x-5)-6=2x+104(2x−5)−6=2x+10

Step 3: Expand.

8x-20-6=2x+108x−20−6=2x+10

Step 4: Simplify  8x-20-68x−20−6  to  8x-268x−26.

8x-26=2x+108x−26=2x+10

Step 5: Add 26 to both sides.

8x=2x+10+268x=2x+10+26

Step 6: Simplify  2x+10+262x+10+26  to  2x+362x+36.

8x=2x+368x=2x+36

Step 7: Subtract 2x2x from both sides.

8x-2x=368x−2x=36

Step 8: Simplify  8x-2x8x−2x  to  6x.

6x=36

Step 9: Divide both sides by 6.

x= 36/6 as a fraction

Step 10: Simplify  \frac{36}{6} to 6.

x= 6x

[tex] \bold{4(2x - 5) -6 = 6+9) + (2x - 5)}[/tex]

[tex] \bold{4(2x−5)−6=6+9+2x−5}[/tex]

[tex] \bold{4(2x−5)−6=2x+10}[/tex]

[tex] \bold{8x−20−6=2x+10}[/tex]

[tex] \bold{8x=2x+10+26}[/tex]

[tex] \bold{8x=2x+36}[/tex]

[tex] \bold{6x=36}[/tex]

[tex] \bold{x = \cfrac{36}{6}} [/tex]

[tex] \bold{x = 6}[/tex]

Note: The Parentheses must be eliminated to then use the law of signs, then we must expand the numbers, then simplify (that is, subtract) Now in the next step is to Add 26 on both sides then we must subtract and then add until we get the result of 6, so that ultimately we can take out a fraction and give us the correct answer, which is [tex]\bold{x=6}[/tex]

The curved surface area of a right circular cylinder of height14 cm is 88 cm2. Find the diameter of the base of the cylinder.

Answers

Answer:

4

Step-by-step explanation:

The formulae for Curved surface

area = πrh

Area = 88cm2

height = 14cm

radius = ?

Let π be 22/7

88 = 22/7 x r x 14

cross multiply

88 x 7 = 22 x 14 x r

616 = 308r

Divide both sides by 308

r = 2

Diameter = Radius x 2

so our radius is 2, 2 x 2 = 4

What is a function?

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The function is given below.

g(x) = x² - 2

The value of the function at x = -2 is given as,

g(-2) = (-2)² - 2

g(-2) = 4 - 2

g(-2) = 2

The value of the function at x = -1 is given as,

g(-1) = (-1)² - 2

g(-1) = 1 - 2

g(-1) = - 1

The value of the function at x = 1 is given as,

g(1) = (1)² - 2

g(1) = 1 - 2

g(1) = - 1

The value of the function at x = 3 is given as,

g(3) = (3)² - 2

g(3) = 9 - 2

g(3) = 7

If the domain of the function is (-2, -1, 1, 3). Then the range of the function will be (1, -1, -1, 7).

Answers

Answer:

Step-by-step explanation:

Given the expression

-4b + 8c + 12 – 8b – 2c + 6.

To simplify, first collect the like terms

= (-4b-8b)+(8c-2c)+(12+6)

= -12b+6c+18

Factor out the GCF

The GCF is 6

On factoring out;

= 6(-2b+c+3)

If b = 2 and c = -3 the expression becomes:

= 6(-2(2)+(-3)+3)

= 6(-4-3+3)

= 6(-4+0)

= 6(-4)

= -24

Hence the value of the expression when b = 2 and c = -3 is -24

Your family drives across Kansas on Interstate 70. A sign reads, “Wichita 90 mi, Topeka 110 mi”. What is the possible range of distances between the two cities given that the cities are not collinear?

Answers

Answer:

20 miles < The distance between the cities < 200 miles

Step-by-step explanation:

The given information on the sign = "Wichita 90 mi, Topeka 10 mi"

Given that the two cites are not colinear, we have;

The number of points specified in the figure = 3 points

The specified points are;

1) The location of the family

2) The location of Wichita, relative to the family's location, = 90 mi

3) The location of Topeka, relative to the family's location, = 110 mi

Therefore, given that the three points are not colinear, they form the vertices of a triangle

The legs of the triangle are 90 mi and 110 mi

The maximum distance between Wichita and Topeka is therefore = 90 + 110 = 200 miles

The minimum distance distance from Wichita to Topeka = 110 - 90 = 20 miles

Therefore, the possible range of distances between the two cities is 20 miles to 200 miles.

Which gives;

20 miles < The distance between the cities < 200 miles.

-0.4

Step-by-step explanation:

You need to combine like terms, whatever that means. So you would add 2x and 3x to get 5x, and then 4+(-2), which would get you to 5x+2=0. Next, you subtract 2 from both sides, so you have 5x=(-2), and then you have to divide both sides by 5.
