Use the picture I provided to help me answer the question.

Answer:

b= -18

Step-by-step explanation:

See attached image.

Formulate the equation for the line by calculation the slope and adding the y-intercept, as shown.  The y-intercept if the value of y when x = 0.  The equation of a straight line is y=mx+b, where m is the slope and b is the y-intercept.  Note that this b is not the same b in the question (8,b).  The b in the question may be calculated once the equation is found:  y = -3x+6, where -3 is the slope and 6 is the y-intercept (0,6).

Use x = 8 in this equation.  y = -3(8)+6,  y = -18

The point is (8,-18), so b is -18.

The two numbers are -9 & 9

In elementary mathematics, a number line is a picture of a graduated straight line that serves as visual representation of the real numbers. Every point of a number line is assumed to correspond to a real number, and every real number to a point.

Given here: Two opposite numbers who have a difference of 18

Thus the two numbers must be 9 units from either side of the origin.

Therefore the only possible number is -9 & 9

Hence, The two numbers are -9 & 9

Answer:

THE 18 oz CONE IS BETTER VALUE, AS YOU GET MORE FOR A CHEAPER PRICE.

Step-by-step explanation:

work out the worth for 1oz of each ice cream cone.

$6.60 / 18 = 0.37 (to 1 decimal place)

$4.75 / 12= 0.40 ( to 1 decimal place)

The rate of change of the area as a function of time is:

A'(t) = 6.28*(R₀ + 4ft/min*t)*(4ft/min)

Remember that for a circle of radius R, the area is:

A = 3.14*R^2

Now, if the radius increases at a rate of 4 ft/min, then we can rewrite R as:

R(t) = R₀ + 4ft/min*t

Where t is the time in minutes, and R₀ is the initial radius.

So the area function is:

A(t) = 3.14*(R₀ + 4ft/min*t)^2

The rate of change is given by the differentiation with respect to t, it is:

A'(t) = 2*3.14*(R₀ + 4ft/min*t)*(4ft/min)

A'(t) = 6.28*(R₀ + 4ft/min*t)*(4ft/min)

The rate at which the area increases, as a function of time, is given by:

A'(t) = 6.28*(R₀ + 4ft/min*t)*(4ft/min)

The sequence 3, 1,1/3 is a geometric sequence

The 7th term of the sequence is 1/243

The sequence is given as:

3, 1,1/3

The above sequence is a geometric sequence with the following parameters:

The nth term is then calculated as:

Tn = ar^(n-1)

So, the 7th term is:

T7 = ar^6

Substitute known values

T7 = 3 * (1/3)^6

This gives

T7 = 1/3^5

Evaluate

T7 = 1/243

Hence, the 7th term of the sequence is 1/243

Answer:

The value of a is 7.

Step-by-step explanation:

To calculate mean, add all of the numbers in the set and divide by the number of terms in said set. There are 7 numbers in this set, so the equation can be set up as follows.

(4 + 10 + 3 + 6 + a + 9 + 10)/7 = 7

Simplify the terms on the top.

(42 + a)/7 = 7

Multiply both sides by 7.

42 + a = 49

Subtract both sides by 42.

a = 7.

Proof:

(4 + 10 + 3 + 6 + a + 9 + 10)/7 = 7

Substitute variable.

(4 + 10 + 3 + 6 + 7 + 9 + 10)/7 = 7

Add in the parenthesis.

49/7 = 7

Divide.

7 = 7.

Answer:

4.9 × [tex]10^3[/tex]

Step-by-step explanation:

Start by doing what is in the paranthesis from right to left.

[tex]9 * 10^2 = 900[/tex]

and

[tex]4 * 10^3 = 4000[/tex]

So if we add them we get:

[tex]900 + 4000 = 4900[/tex]

Now to put it into standard form we just put a decimal to the right of the first number and see how many times we need to move right in order to make the number. In this case it's 3 times so we tack on × [tex]10^3[/tex]

So our answer is:

Step-by-step explanation:

ABE is tangent to the circle then m∡OBE = m∡OBD = 90

Then m∡OBD = 90 - 58 = 32

In the triangle DAB :

                                = 180 - [     32       + (90 + 32)]

                                = 180 - [     32       + ( 122) ]

Answer:

y < 1/2 x - 3

Step-by-step explanation:

The line crosses the y-axis (up and down numbered axis) at -3. That's the - 3 in the equation. If you look very carefully, closely, you can see that the line, from there, goes UP1 and OVER2 to get to the next point (and the next point and the next point) This is the slope, it goes in front of the x, here it is UP1 and OVER2 and is written 1/2.

The line is dashed so the symbol is < "less than" WITHOUT the line mark underneath it; also because the shading is BELOW the dashed line we use < "less than" and not > "greater than"

A = 6400 m²

Step-by-step explanation:

the sides s of a square are congruent , then

s = 320 ÷ 4 = 80 m

tahe area (A) of a square is calculated as

A = s² = 80² = 6400 m²

The required area of square, having side 80 meters, is 6400 square meters.

A square is a quadrilateral with four equal sides and four equal angles that is a regular quadrilateral. The square's angles are at a straight angle or 90 degrees.

Given that,

The length of fencing enclosure a square = 320 meters,

Let the side of the square is a meter,

According to given condition, perimeter of square,

4a = 320  

a = 80

Since, the area of square having side a, is a²

Area = a²

Area = (80²)

Area = 6400 square meters.

The area of square, having side 80, is 6400 square meters.

Each of the different groups or selections can be formed by taking some or all of a number of objects, irrespective of their arrangments is called a combination.

Here we have 4 selections.

Now let's find the number of options for each of these:

First character = 9 options {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Second character = 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Third character = 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Fourth character = 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
