<h3>One less than the product of four and a number is 11. What is that number ?</h3>

Answer: The number is 3

Step-by-step explanation:

We will call X the number, then 4X - 1 = 11

4X = 11 + 1 =12

X = 12/4 =3

This is the number = 3

olasank [31]

Answer:

y=-1/3x+4/3

Step-by-step explanation:

y-y1=m(x-x1)    m=1/3 x1=3 y1=2

y-2=1/3(x-2)

y-2=-1/3x-2/3

y=-1/3x+4/3

What is the value of f(x)=2•2^x for f(-2)
Zigmanuir [339]

Answer:

The value of f(-2) is 1/2 or it can be written as 0.5.

Step-by-step explanation:

The given function is

f(x)=2\cdot 2^x

We have to find the value of f(-2).

Substitute x=-2 in the given function to find the value of f(-2).

f(-2)=2\cdot 2^(-2)

f(-2)=2\cdot \frac{1}{2^(2)}

f(-2)=\frac{1}{2}

f(-2)=0.5

Therefore the value of f(-2) is 1/2 or it can be written as 0.5.

Estimate the perimeter of the figure to the nearest whole number.
Paha777 [63]

Answer:

The perimeter (to the nearest integer) is 9.

Step-by-step explanation:

The upper half of this figure is a triangle with height 3 and base 6.  If we divide this vertically we get two congruent triangles of height 3 and base 3.  Using the Pythagorean Theorem we find the length of the diagonal of one of these small triangles:  (diagonal)^2 = 3^2 + 3^2, or (diagonal)^2 = 2*3^2.

Therefore the diagonal length is (diagonal) = 3√2, and thus the total length of the uppermost two sides of this figure is 6√2.

The lower half of the figure has the shape of a trapezoid.  Its base is 4.  Both to the left and to the right of the vertical centerline of this trapezoid is a triangle of base 1 and height 3; we need to find the length of the diagonal of one such triangle.  Using the Pythagorean Theorem, we get

(diagonal)^2 = 1^2 + 3^2, or 1 + 9, or 10.  Thus, the length of each diagonal is √10, and so two diagonals comes to 2√10.

Then the perimeter consists of the sum 2√10 + 4 + 6√2.

which, when done on a calculator, comes to 9.48.  We must round this off to the nearest whole number, obtaining the final result 9.
