Evaluate 6z-2z for z=4

Answers

Answer 1

The value of the expression for the given value of z is 16

Substitution and evaluation

From the question, we are to evaluate the given expression for the given value of unknown

The given expression is 6z - 2z

We are to evaluate this expression for z = 4. To do this, we will put in the value of 4 for z in the expression and simplify.

That is,

6z - 2z becomes

6(4) - 2(4)

Simplifying

24 - 8

= 16

Hence, the value of the expression for the given value of z is 16.

A car moving at a constant speed travels 88 feet in 2 seconds. Use a proportion to find how many feet it travels in one minute.

20 points??? :D

Answers

Answer:

we know that it can travel 88 feet in 2 seconds, this means that it can travel 30x that amount in a minute since 2 is 1/30 of a minute.

so  basically 88ft/2sec= 2640ft/1min.  the car can travel 2640 feet in a minute

What is the slope of the line y=1/6x+3/2

Answers

Answer:

1/6

Step-by-step explanation:

When the y is isolated on one side and is not multiplied by anything (other than one), the slope is the value before the x. In this case, it's 1/6. And in if y is perfectly isolated, then the y-intercept is the value after the x, which is positive 3/2 in this case.

Freddie travels east 5 km and then goes north for 12 km and then west for 5 km what is his distance and displacement

Answers

Answer:

12 km

Step-by-step explanation:

going east by 5 km and then west by 5 km brings him 12 km to the north of where he started

Freddie's displacement is a vector with a length of 12 km pointing straight up (in the positive y direction).

What is displacement?

Displacement is the distance between the final point and the initial point.

We have,

Freddie's distance traveled is the total length of the path he took, regardless of direction.

To find the distance, we can use the Pythagorean theorem, since he moved in a right-angled triangle:

distance = √(5² + 12² + 5²) = √(25 + 144 + 25) = √194 ≈ 13.928 km

So Freddie's distance traveled is approximately 13.928 km.

Freddie's displacement is the straight-line distance and direction from his starting point to his ending point.

We can represent his movements using vector notation:

East: 5 km to the right = +5 km in the x direction

North: 12 km upwards = +12 km in the y direction

West: 5 km to the left = -5 km in the x direction

The total displacement is the vector sum of these three movements. To calculate this, we can add up the x components and y components separately:

x displacement = +5 km - 5 km = 0 km

y displacement = +12 km

Thus,

Freddie's displacement is a vector with a length of 12 km pointing straight up (in the positive y direction).

Answer:

22

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable. x = 22

Answer:

22

Step-by-step explanation:

The diagonals are divided into 2 parts. They're both equal to each other in order to equal the total length.

Setting them up to equal each other is the easiest way to solve.

2x + 18 = x + 40.

Now with simple algebra, we can find the sidelength of x.

Subtract both sides by x.

x + 18 = 40

Subtract both sides by 18.

x = 22.

a grocer stacks apples in a pyramid-like stack whose rectangular base is 7 apples by 5 apples. each apple above the first level rests in a pocket formed by 4 apples below. the stack is completed by a singles row of apples. how many apples are in he stack

Answers

The arrangement of the apples in the stack is in a sequence that can be

used to find the number of apples in each row and in the stack.

Correct response:

The number of apples in the stack are 85 apples

How to find the sum of a sequence

The given parameters are;

Dimensions of apples in the rectangular base = 7 apples by 5 apples

Number of apples on which each apple above rests = 4 apples

Required:

The number of apples in the stack.

Solution:

The dimensions, length and width of the apples in each row decreases

by 1 compared to the row on which the apple rests, as follows;

In the base, the dimension = 7 by 5

In the row directly above, the dimension = (7 - 1) by (5 - 1)

The number of apples sequence continues and is completed by a singles row of apples at the top, from which gives;

Number of apples in the stack = 7 × 5 + 6 × 4 + 5 × 3 + 4 × 2 + 3 × 1 = 85

Hi!

In the screenshot provided, the first graph has a positive slope, but in the second graph, the slope is negative.

Here's why:

When trying to find out if the slope is positive or negative, you look to see which direction the line in pointing.

In this case, in graph one, the line is going up so this means that the slope is positive. In graph two, the line is going down, so this means that the slope is negative.

Answers

The cost for one steak burger is $4.5. The price/ The cost of one order of fries is $2.25

Solution

Let one steak burger cost $x

and one fries order cost $y

Hence, we have

3x+2y = 18-----------1

2x+3y = 15.75-------2

Let us solve the equation simultaneously

multiply equation 1 by 2 and equation 2 by 3

6x + 4y = 36 ---------3

6x +  9y = 47.25 ----4

subtraction 4 from 3 we have

0x -5y = -11.25

Divide both sides by -5

y = 11.25/5

y = $2.25

Put y = 2.25 in equation 1 to find x

3x+2(2.25) = 18-----------1

3x + 4.5 = 18

3x = 18 -4.5

3x = 13.5

x = 13.5/3

Find the inverse of the function.

The inverse of g(x) = ___

Answers

Answer:

Step-by-step explanation:

The inverse is found by interchanging the x and y values and solve the result for y.

I will use y for f(x)

y = 4x^2

Inverse

x = 4y^2              Divide by 4

x/4 = 4y^2 /4    

x/4 = y^2             Take the square root of both sides.

sqrt(x/4) = sqrt(y^2)

y = sqrt(x/4)

g(x) = sqrt(x/4)  If you have a very fussy teacher, the inverse function could be written as

g(x) = +/- sqrt(x)/2

I expect that if the question is computer marked, I would try g(x) = sqrt(x)/2 first.
