• How can you check whether a point is the solution to a system?

Answers

Answer 1

Answer:

In other words, the solution is the point where the two lines intersect. To verify whether a point is a solution to a system or not, we will either determine whether it is the point of intersection of two lines on a graph or we will determine whether or not the point lies on both lines algebraically

Answers

The discriminant of the function is 120, and the function has 2 different x-intercepts

How to determine the discriminant?

The function is given as:

f(x) = -7x^2 + 8x + 2

The discriminant (d) is calculated using:

D =b^2 - 4ac

So, we have:

D = 8^2 - 4 * (-7) * 2

Evaluate

D = 120

Because the value of D is greater than 0, then the function has 2 different x-intercepts

Step-by-step explanation:

The relations between angles and arcs in this problem set are ...

The sum of central angles in a circle is 360°The measure of an arc is the measure of the central angle it subtendsThe measure of an inscribed angle is half the measure of the arc it subtends

Arc DBC is the difference between a full circle (360°) and short arc DC. The measure of short arc DC is marked as 96°, so ...

  arc DBC = 360° -96° = 264°

5.

Αrc BC is twice the measure of the inscribed angle BDC it subtends.

  arc BC = 2×60° = 120°

6.

Arc AB is the difference between 360° and the sum of arcs AD, DC, and CB.

  arc AB = 360° -(90° +96° +120°) = 54°

7.

Angle ACD is half the measure of arc AD.

  Angle ACD = 90°/2 = 45°

8.

Angle ADC is half the measure of arc AC, which is the sum of arcs AB and BC

  angle ADC = (54° +120°)/2 = 87°

Angle ACB is half the measure of arc AB

  angle ACB = 54°/2 = 27°

If f(x) = 3x+ 2 and g(x) = 2x-2, what is (f-8)(x)?

Answers

Answer: x + 4

Step-by-step explanation:

    If it is asking us for (f - g)x, then we will subtract the function g from function f. Why? The x distributes creating f(x) - g(x), so we use this to solve.

   Given:

g(x) = 2x - 2

f(x) = 3x + 2

   Set up:

f(x) - g(x)

(3x + 2) - (2x - 2)

   Distribute the negatie:

3x + 2 - 2x + 2

   Reorder to combine like terms:

3x - 2x + 2 + 2

   Combine like terms:

x + 4

    (f - g)(x) = x + 4

Melody need 155 bags of 140 cu. inches to fill the vegetable garden.

What is Volume of Cuboid?

The volume of the cuboid is the measure of the space occupied within a cuboid. The cuboid is a three-dimensional shape that has length, breadth, and height.

Here, Length of vegetable garden = 48 inch

          breadth of garden = 30 inches

          height of garden = 15 inches

Volume of garden = Length X width X height

                              = 48 X 30 X 15

                              =  21600 cu. inches

Volume of each bag = 140 cu. inches

Number of Bags required = Volume of garden/Volume of each bag

                                            = 21600 / 140

                                            ≈ 155

Not only would I like the value of x, but also I wonder how I’d go about solving this problem?

Answers

Answer:

x = 58

Step-by-step explanation:

This question can be solved by using the exterior angle property, which states that the exterior angle of a triangle = the sum of the two opposite interior angles.

62 lies on a line, so the exterior angle is 180 - 62, or 118 degrees.

Using the EAP, we can conclude the following:

(x + 2) + (x) = 118

2x + 2 = 118

2x = 116

x = 58

Hope this helps

Answer:

X=58

Step-by-step explanation:

1.)  62+2+2x=180  

2)  64+2x=180    (add 62 and 2)

3) 2x=116  (subtract 64 from 180)

4)x=58  (divide 116 by 2 =58

How to determine the value of P(B)?

The given parameters are:

P(A) = 0.50

P(A and B) = 0.20

Two events A and B are independent, if

P(A and B) = P(A) * P(B)

So, we have:

There are 16 cups in a gallon (16 x 2)
There are 128 ounces in a gallon (128 x 2)

With that being said, we can add these to find the total amount of gallons of beverages Julius bought. 16 + 8 + 8 + 32 + 256 = 320.
