Answer:

y = - 3

Step-by-step explanation:

the midline is a horizontal line positioned midway between the maximum and minimum values of the graph.

maximum = - 1 and minimum = - 5

then

(- 1 + (- 5)) ÷ 2 = (- 1 - 5) ÷ 2 = - 6 ÷ 2 = - 3 so equation of midline is

y = - 3

Answer:   \(w \le 3000\)

w is the weight of the truck in pounds.

Since w cannot be negative, we can write \(0 \le w \le 3000\) or we could tack on the statement "w must be positive"

The phrase "at most" means "that is the largest w can get". Think of it as the ceiling.

Answer:

m = p/5 - 10

Step-by-step explanation:

Divide both sides by 5

P/5 = m + 10

Subtract 10 from both sides.

P/5 - 10 = m

Switch sides.

m = p/5 - 10

The length of WZ is 7.5 inches and the measurement of angle Y is 45 degrees for the similar shapes QRST and WXYZ.

Similar shapes are two or more shapes that have the same shape, but different sizes. In other words, they have the same angles, but their sides are proportional to each other. When two shapes are similar, one can be obtained from the other by uniformly scaling (enlarging or reducing) the shape.

If Lynn's quadrilateral WXYZ is a smaller shape of QRST, and they are similar, then:

the side QR corresponds to WX and QR corresponds to WX, so:

QR/WX = QT/WZ

2/5 = 3/WZ

WZ = (3 × 5)/2 {cross multiplication}

WZ = 15/2

WZ = 7.5

The angle RST corresponds to XYZ, so:

angle S = angle Y = 45°

Therefore, length of WZ is 7.5 inches and the measurement of angle Y is 45 degrees for the similar shapes QRST and WXYZ.

The area and the perimeter are 18x^2 + 63x and 22x + 14

The given parameters are

Length = 9x

Width = 2x + 7

The area is calculated as

Area = Length * Width

So, we have

Area = 9x * (2x + 7)

This gives

Area = 18x^2 + 63x

The perimeter is calculated as

P = 2 * (Length + Width)

So, we have

P = 2 * (9x + 2x + 7)

Evaluate

P = 22x + 14

Hence, the area and the perimeter are 18x^2 + 63x and 22x + 14

Answer:

X = 4x-18

Step-by-step explanation:

X = “a number”^^

The value of x will be -7. The expression is solved using the identity.

Exponents can also be written as logarithms. The other number is equal to a logarithm with a number base. It's the exact inverse of the exponent function.

Given expression;

\(\rm log_2(\frac{1}{128}) = x\)

The expression is solved using the identity as;

\(\rm log_e1 = x\\\ e^x=1\)

Apply the identity;

\(\rm log_2(\frac{1}{128}) = x \\\\ 2^x = \frac{1}{128}\\\\ 2^x = \frac{1}{2^7} \\\\ 2^x = 2^{-7} \\\\ x = -7\)

Hence the value of x will bed -7.

The fraction that is equivalent to 3/4 is seen as; 6/8

A number sentence is defined as a mathematical sentence that is made up of numbers and symbols.

We want to write a number sentence using multiplication to show a fraction that is equivalent to 3/4.

Now, for us to find the final equivalent fraction, what we have to do is that we will divide or multiply by  denominator and numerator by the same number that is equal to one e.g 3/3; 5/5; 6/6, etc.

Since we want to find equivalent fraction of 3/4, let us multiply both numerator and denominator by 2 to get;

(3 * 2)/(4 * 2) = 6/8

Answer:

  y = -3

Step-by-step explanation:

The y-axis is a vertical line, so the perpendicular line is a horizontal line. It is generally written in the form ...

  y = constant

For the line to go through the point (-5, -3), the constant must match the y-coordinate of the point: -3

  y = -3 . . . . your equation

__

Such a line has a slope of 0, so could be written in "slope-intercept form" as ...

  y = 0x -3

We generally omit terms that evaluate to zero.

Answer:

  (c)  The x-intercept of f⁻¹(x) is the same as the y-intercept of f(x).

Step-by-step explanation:

You want to know the relationship between the graphs of function f(x) and its inverse f⁻¹(x).

The inverse of a function maps every y-value of the original function to its corresponding x-value. That is if you have ...

  f(a) = b

then the graph of f(x) contains the ordered pair (a, b).

The inverse function will have the ordered pair (b, a). That is,

  f⁻¹(b) = a

If an ordered pair (x-intercept) of the inverse function is ...

  (P, 0)

Then there will be an ordered pair (0, P) on the graph of the original function. That point is the y-intercept, and its y-coordinate is the same as the x-coordinate of the x-intercept of the inverse function.

The x-intercept of f⁻¹(x) is the same as the y-intercept of f(x).

__

Additional comment

The graphs of the two functions are mirror images of each other across the line y=x.

The 19th term of a geometric sequence is 1048576.

A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.

We have,

a = 4 and r = 2

The nth term of a geometric sequence.

= a\(r^{n-1}\)

Now,

The 19th term of a geometric sequence.

= a\(r^{n-1}\)

Substituting a and r values.

= 4 x \(2^{19 - 1}\)

= 4  x \(2^{18}\)

= 4 x 262144

= 1048576

Thus,

The 19th term of a geometric sequence is 1048576.
