Answer:

a) x <= 15 b) x > 16.5 c) x < 34.5 d) x =/= 23

Step-by-step explanation:

For a), there is a shaded region for where 15 is, and the number line is going towards the left, so x will be less than but also equal to 15

For b), there is not a shaded region for where 16.5 is, but the number line is going towards the right, so x will be greater than 16.5

For c), there is not a shaded region for where 34.5 is, but the number line is going towards the left, so x will be less than 34.5

For d), there is not a shaded region for where 23 is, but the number line is going everywhere else so it is x =/= 23(x does not equal to 23)

Answer:

Step-by-step explanation:

Let x = number of hours.

Let y = cost.

The fixed cost is $11.

The cost per hour is $2.

For x hours, the cost per hour is 2x.

y = 2x + 11

23 = 2x + 11

12 = 2x

x = 6

Answer: 6

Solution :

Trigonometry is that branch of mathematics which is used to study the relationship between the angles and the lengths of the sides of a triangle.

We known that the co-ordinate of a point on the circumference of a circle making an angle θ with the horizontal having a unit radius is given by :

(1 cos θ, 1 sin θ).

And for any angle made by sin θ on the x - axis is 0 and on the y -axis is 1 or -1 depending on the quadrant.

Since, angle 270 degree falls on the 3rd quadrant, therefore, the value of the co-ordinates of the point is (cos θ, sin θ) = (0,-1).

So the value of sin 270° = -1.

One other example of sin θ = 1 is 90° as 90 degree falls in the first quadrant.

Step-by-step explanation:

total mass of people = 50× 5 = 250kg

height = 20m

force = mass × g = 250× 10 ( taking g= 10m/s²)

work done = force × distance

Step-by-step explanation:

[tex]\frac{1}{3} (12x + 6x -21)[/tex]

break it into pieces

[tex]\frac{1}{3}*12x = 4x[/tex]

[tex]\frac{1}{3}*6x=2x[/tex]

[tex]\frac{1}{3} *-21=-7[/tex]

put it all together

*since there's no negative in front  of the other numbers except 7 they're positive so you add them*

[tex]4x + 2x - 7[/tex]

Given:

Length of a box is 9 inches, width is 2 inches and height is 1.5 inches.

The cost of silver coating is $2.50 per sq. inches.

To find:

The total cost of silver coating for the box.

Solution:

The total surface area of a cuboid is

[tex]A=2(lb+bh+hl)[/tex]

Where, l is length, b is breadth and h is height.

Putting [tex]l=9,b=2,h=1.5[/tex], we get

[tex]A=2(9\times 2+2\times 1.5+1.5\times 9)[/tex]

[tex]A=2(18+3+13.5)[/tex]

[tex]A=2(34.5)[/tex]

[tex]A=69[/tex]

So, the total surface area of the box is 69 square inches.

Cost of silver coating is $2.50 per sq. inches. So, the cost of silver coating for the box is

[tex]Cost=69\times 2.50[/tex]

[tex]Cost=172.50[/tex]

Therefore, the cost of silver coating for the box is $172.50.

Answer:

(4,-1)

Step-by-step explanation:

x is 4 y is -1

Answer:

(2,1)

Step-by-step explanation:

Let's solve your system by elimination.

6x−7y = 5;−4x+7y=−1

6x−7y=5

−4x+7y=−1

Add these equations to eliminate y:

2x = 4

Then solve2x = 4for x:

2x = 4

(Divide both sides by 2)

x = 2

Now let's plug x in to solve for y.

6x - 7y = 5

6(2) - 7y = 5

12 - 7y = 5

subtract 12 on both sides.

-7y = -7

divide both sides by -1

y = 1

(7/5 , 7/5)

Answer:

2y = -3x + 7

Step-by-step explanation:

(3, -1) and (-1, 5)

Slope:

m=(y2-y1)/(x2-x1)

m=(5+1)/(-1-3)

m=6/(-4)

m= -3/2

Slope-intercept:

y - y1 = m(x - x1)

y + 1 = -3/2(x - 3)

y + 1 = -3/2x + 9/2

y = -3/2x + 7/2

Standard form:

y = -3/2x + 7/2

3x + 2y = 7

2y = -3x + 7

Answer:

Florida = 345 feets

Delaware = 451 feets

Louisiana = 535 feets

Step-by-step explanation:

Given that:

Let :

Highest elevation in Florida, = x

Highest elevation in Delaware = x + 106

Highest elevation in Louisiana = x + 190

Sum of highest elevation in the 3 states = 1331 feets

Hence,

x + x + 106 + x + 190 = 1331

3x + 296 = 1331

3x = 1331 - 296

3x = 1035 feets

x = 1035 / 3

x = 345 feets

Hence,

Highest elevation in Florida, = x = 345

Highest elevation in Delaware = 345 + 106 = 451

Highest elevation in Louisiana = 345 + 190 = 535

Answer:

D) The account balance increases by an additional $100 for each deposit

Step-by-step explanation:

The y intercept will always be the number being added or subtracted from the independent variable.

The y intercept of y = 75x + 100 is 100, it means that the starting savings account balance is $100.

A linear equation is in the form:

y = mx + b

Where m is the rate of change and b is the y intercept.

Given the equation:

y = 75x + 100

The y intercept is 100, it means that the starting savings account balance is $100.
