Which is an equation of the function graphed?

A. Y=-2x^2+4x-2
B. Y=-2x^2-4x+2
C. Y=-2x^2-4x-2
D. Y=-2x^2+4x+2

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.

(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:

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:

120 cm cubed

Step-by-step explanation:

first we need to find the size of the triangular face. we can do this by taking the height and with of the base, multiplying them, then dividing by two (3*8)/2

which gives us 12, so now we multiply by 10 to get the volume of the full prism. 12*10=120

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.

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.

Step-by-step explanation:

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

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:

  (x, y) = (-1, -3)

Step-by-step explanation:

You notice that the coefficient of x in the first equation is double the opposite of the coefficient of x in the second equation. This means we can make the x-term disappear by adding twice the second equation to the first.

  (-6x +8y) +2(3x) = (-18) +2(y)

  8y = -18 +2y . . . simplify

  6y = -18 . . . . . . . subtract 2y

  y = -3 . . . . . . . . . divide by 6

Substituting into the second equation, we have ...

  3x = -3

  x = -1 . . . . . . . . . divide by 3

The solution is (x, y) = (-1, -3).

Step-by-step explanation:

Complete question

A stainless steel patio heater is a square pyramid. The length of one side of the base is 89.6 The slant height of the pyramid 90.1. What is the height of the​ pyramid?

To get the height of the pyramid, we will use pythagoras theorem.

slant height l is the hypotenuse

length of the base is the adjacent

height of the pyramid is the opposite

According to the theorem;

l² = h² + b²

90.1² = h² + 89.6²

8,118.01 = h²+8,028.16

h²= 8,118.01 - 8,028.16

h² = 89.85

h =√89.85

h = 9.48

Hence the height of the pyramid will be 9.48

Note that the value of the slant height was assumed to solve the problem.

Answer:

6

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
