what are the numbers between 8 and 9​

Step-by-step explanation:

2A and 2B are scalar multiplications : every item in the matrix has to be multiplied by that factor.

the subtraction then of 2A - 2B is simply to subtract every positive in B from the corresponding same position in A.

that is all.

2A =

4 0

-6 2

2B =

0 2

-4 6

2A - 2B =

4-0 0-2

-6--4 2-6

=

4 -2

-2 -4

Answer: -2, 1, all real numbers, all real numbers

Step-by-step explanation:

g o f(n) is basically g(f(n))

Using the question as an example we can get that f(0) = 1 so

g(f(0)) = g(1) = -2

f(1) = 0 so g(f(1)) = g(0) = 1

The domain of f(x) is all real numbers and the range of g(x) is all real numbers

Answer:

Step-by-step explanation:

A relation is a function if there is only one y-value for each x-value. If you can draw a vertical line on the graph that intersect more than one point, the relation is not a function. (This is the "vertical line test.")

Graph A: there are 3 y-values associated with x=2. Not a function.

Graph B: passes the vertical line test: A function.

Graph C: there are 2 y-values at each of x=1 and x=2. Not a function.

Answer:

y=2x-11

Step-by-step explanation:

arralel lines have same gradient

since gradient of the known line is 2( the coefficient of x), it therefore follows that the gradient of the second line we want to find is also 2

So we know the gradient of the second line is 2, and we have one known point (7,3). We can therefore apply the formula for finding gradient to come up with the line

[tex]2=\frac{y-3}{x-7} \\\\y-3=2(x-7)\\\\y-3=2x-14\\\\y=2x-14+3\\\\y=2x-11[/tex]

Answer: $412.50

Step-by-step explanation:

The area of the square formed by combining the painting and the molding is [tex](25)(28)=700[/tex] square inches.

The area of the painting itself is [tex](22)(25)=550[/tex] square inches.

Therefore, the area of the molding is [tex]700-550=150[/tex] square inches, and thus costs [tex](150)(2.75)=\$412.50[/tex]

Average speed is the total distance travelled per time.

Average speed = total distance / total time

Tyler's average speed =  1 / 8.30 seconds = 0.12 miles per minute

The distance covered by Tyler in 10 minutes = 0.12 x 10 = 1.2 miles

The value of the equation is A = 12p , where p is the number of packages of batteries

Equations are mathematical statements with two algebraic expressions on either side of the equals (=) sign.

It depicts how the expressions on the left and right sides are linked together.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are all parts of an equation. When creating an equation, the "=" symbol and terms on both sides are necessary.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the number of packages be represented as p

Let the number of batteries in one package = 12 batteries

So , the total number of batteries in p packages A = number of packages x number of batteries in one package

The way you do this is use the quadratic formula to solve for the x intercepts which are [tex](\frac{1+\sqrt{2} }{2} )[/tex] and [tex](\frac{1-\sqrt{2} }{2})[/tex]

The algebraic expression is x > 2x + 1 and simplification form of the algebric expression is x < -1

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have:

The number that is x more than 2x+1

x is the number.

x > 2x + 1

After simplification:

2x - x < -1

x < -1

x ∈ (-∞, -1)

Thus, the algebraic expression is x > 2x + 1 and simplification form of the algebric expression is x < -1

Answer:

y ≤ 2.5x-3

Step-by-step explanation:

we know two points: (2 , 2 ) and ( 0 , -3)

[tex]Grad = \frac{2--3}{2-0} =\frac{5}{2} =2.5\\[/tex]

we also know the y intercept is -3

therefore equation in question is : [tex]y = 2.5x-3[/tex]

we take any point either above the line or below the line and substitute in the equation above. Let us try point (0,0) which is above the line and in the unwanted(shaded region):

y = 2.5x-3

0=2.5(0)-3

0=-3

Normally 0 can  never be equal to -3 but is ≥ -3.

Since the point taken was not in the wanted region we reverse ≥  to ≤  to show the wanted region. The inequality in question becomes :

y ≤ 2.5x-3

Answer:

  72 guests

Step-by-step explanation:

We can add up the numbers of bottles per guest, then use that total to find the number of guests from the number of bottles.

Let g represent the number of guests at the party. Then there are ...

The total number of bottles is ...

  g(1/3 +1/6 +1/4) = 54

Multiplying by the inverse of the coefficient of g, we find its value to be ...

  g(4/12 +2/12 +3/12) = g(9/12) = 54

  g = 54(12/9) = 72

There are 72 guests at the party.

Answer:

C.

Step-by-step explanation:

Answer:

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to help you remember the relationships between sides of a right triangle and trig functions of the acute angles. It tells you ...

The given triangle shows values of an acute angle and its opposite side. You are to find the other two sides in the triangle, as well as the other acute angle.

X is the side adjacent to the given angle, so the relevant trig relation is ...

  Tan = Opposite/Adjacent

  tan(25°) = (4 ft)/X

Solving for X gives ...

  X = (4 ft)/tan(25°) . . . . . . . . multiply by X/tan(25°)

  X ≈ 8.58 ft

Y is the hypotenuse, so the relevant trig relation is ...

  Sin = Opposite/Hypotenuse

  sin(25°) = (4 ft)/Y

  Y = (4 ft)/sin(25°) . . . . . . multiply by Y/sin(25°)

  Y ≈ 9.46 ft

The sum of angles in a triangle is 180°, so if one of them is 90°, the sum of the other two is 90°.

  Z = 90° -25°

  Z = 65°

Step-by-step explanation:

since the slope is the same you know they're parallel, but just find the difference from the two y intercepts (the +3/-7) the difference is 10, so 10.

Answer:

B.) The graph of m(x) is wider.

     Both graphs open upward.

     Both have the axis of symmetry x = 0.

     The vertex of m(x) is (0, 4); the vertex of n(x) is (0, 0).

Step-by-step explanation:

When the coefficient before x² is greater than 1, the curve of the graph is narrower. When the coefficient is less than 1, the curve of the graph is wider.

When the coefficient in front of x² is positive, the graph opens upwards. When the coefficient is negative, the graph opens downwards.

The axis of symmetry is the "x" value which divides the curve into two equal sections. Their axis of symmetry are both x = 0 because their vertexes (the lowest point of the curve) are both at x = 0.

The vertex can be found by plugging x = 0 into both of the equations and then solving. The resulting value is the "y" position of the vertex.

m(0) = 0.7(0)² + 4                        n(0) = (0)²

m(0) = 0 + 4                                 n(0) = 0

m(0) = 4

Therefore, the vertexes are m(x) =  (0,4) and n(x) = (0,0).

M2 = unknown

R1 = 4000 miles

R2 = 300 miles

We can deduce that;
