11 - 6x - 12 = -13 -2x

- 6x - 1 = -13 - 2x

-4x - 1 = -13

Is f(x)=7-2x a polynomial function




Step-by-step explanation:


Yes, this F(x) is a polynomial function involving the first and null integer powers of x:  x^0 and x^1.

Final answer:

Yes, f(x) = 7 - 2x is a polynomial function because it satisfies the general form of a polynomial, which requires that every term is in the form ax^n for nonnegative integer n.


Yes, the function f(x) = 7-2x is indeed a polynomial function. A polynomial function is a function such as a quadratic, a cubic, a quartic, and so on, for which the function is of the form f(x) = ax^n, where n is a nonnegative integer. In this case, f(x) = 7-2x can be more comprehensively written as f(x) = -2x^1 + 7x^0, which reflects the general form of a polynomial function.

Let a1equals[Start 3 By 1 Matrix 1st Row 1st Column 1 2nd Row 1st Column 2 3rd Row 1st Column negative 1 EndMatrix ]​, a2equals[Start 3 By 1 Matrix 1st Row 1st Column negative 7 2nd Row 1st Column negative 7 3rd Row 1st Column 2 EndMatrix ]​, and bequals[Start 3 By 1 Matrix 1st Row 1st Column 3 2nd Row 1st Column negative 22 3rd Row 1st Column h EndMatrix ]. For what​ value(s) of h is b in the plane spanned by a1 and a2​?



For h= 25,  b in the plane spanned by a1 and a2​

Step-by-step explanation:

a1= \left[\begin{array}{c}1\n2\n-1\end{array}\right] \na2 = \left[\begin{array}{c}-7\n-7\n2\end{array}\right] \n\nb   = \left[\begin{array}{c}3\n-22\nh\end{array}\right]

we have to find value of h for which  b in the plane spanned by a1 and a2.

For this the linear systems given by the  following augmented matrix must be consistent.


Reduce the augmented matrix into row echelon form:

R_(2) - 2R_(1) , R_(3) + R_(1)\n\n\left[\begin{array}{cc|c}1&-7&3\n0&7&-28\n-0&-5&h+3\end{array}\right]\n\n7R_(3)+5R_(2)\n\n\left[\begin{array}{cc|c}1&-7&3\n0&7&-28\n-0&0&7h-175\end{array}\right]

For system to be consistent:

                         7h-175 =0\n7h=175\nh=25

Consider the triangle reduction.A larger triangle has side lengths 15.4 centimeters, 15.4 centimeters, and 12.4 centimeters. A smaller triangle has a side length of 3.85 centimeters that corresponds to the sides of the larger triangle with lengths 15.4 centimeters.

The perimeter of the original triangle is 43.2 cm. What is the perimeter of the reduced triangle?

In the previous problem, you found the perimeter of a reduced triangle. Explain how you found the new perimeter using proportions.

Please help me with this word problem!Suppose you lay exactly 160 feet of fencing around a rectangular garden. If the length of the garden is 3 times its width, find the dimensions of the garden.
Length: __ feet
Width: __ feet


Step-by-step explanation:

the perimeter (the way one time around it) of a rectangle is

2×length + 2×width

length = 3×width

2×(3×width) + 2×width = 160

6×width + 2×width = 160

8×width = 160

width = 160/8 = 20 ft

length = 3×width = 3×20 = 60ft
