Answer:

(-2, -3)

Step-by-step explanation:

To solve this problem, we use the midpoint formula.

M = $\frac{x1 + x2}{2} , \frac{y1+ y2}{2}$

Plug your coordinates in:

M = $\frac{-7 + 3}{2} , \frac{-8 + 2}{2}$

Simplify:

M = $\frac{-4}{2} , \frac{-6}{2}$

M = (-2,-3)

a contractor needs to buy nails to build a house. the nails come in small boxes and large boxes. each small box has 50 nails and

AleksandrR [38]

Seven huge boxes and two tiny boxes total were bought by the contractor.

A linear equation is defined as an algebraic equation of maximum degree 1 is a linear equation.

According to the question, a builder needs to purchase nails to construct a house.

Both small and large boxes of nails are provided. There are 50 nails in each small box and 350 in each large box.

The contractor purchased 5 more large than tiny boxes, hence it is assumed that he purchased a certain number of little boxes.

He purchased (x+5) huge cartons.

So, 50(x) + 350(x+5) = 2590.

50x + 350x + 1750 = 2590.

400x = 2590 - 1750.

400x = 840.

x = 2.1

The bulk of the boxes he bought is 7.

According to the rational root theron what are all the potential roots of f(x)=9x^4-2x^2-3x+4

Viefleur [7K]

Answer:

Potential roots: $\frac{9}{4},\frac{9}{2},9,\frac{3}{4},\frac{3}{2},3, \frac{1}{4},\frac{1}{2},1$

Step-by-step explanation:

Simply put, the rational roots theorem tells us that if there are any rational roots of a polynomial function, they must be in the form

± $\frac{FactorsOfa_{0}}{FactorsOfa_n}$

Where

a_n is the number before the highest power of the polynomial, and

a_0 is the constant in the polynomial

From the polynomial shown, we have a_n = 9 and a_0 = 4

The factors of 9 are 9, 3, 1

and

The factors of 4 are 4,2,1

So, if there are any rational roots, they would be:

± $\frac{FactorsOfa_{0}}{FactorsOfa_n}$

± $\frac{9,3,1}{4,2,1}$

Which is ± 9/4, 9/2, 9/1, 3/4, 3/2, 3/1, 1/4, 1/2, 1/1

$\frac{9}{4},\frac{9}{2},9,\frac{3}{4},\frac{3}{2},3, \frac{1}{4},\frac{1}{2},1$
