256-192= 64

192-144=48

144-108=36

108-81=27

81- 60.8=20.2

60.8-45.6=15.2

45.6-34.2= 11.4

34.2-25.6=8.6

25.6-19.2= 6.4

19.2-14.4= 4.8

The number of counties in state A and the number of counties in state B are consecutive even integers whose sum is 138 138. If s

ss7ja [257]

Answer:

The number of counties in state A are 70.

The number of counties in state B are 68.

Step-by-step explanation:

The number of counties in state A and the number of counties in state B are consecutive even integers whose sum is 138.

Let the two consecutive even integers be x and x+2.

As their sum is 138, we can denote this mathematically as :

$x+x+2=138$

$=> 2x+2=138$

$=> 2x=138-2$

$=> 2x=136$

Now, we get x = 68

And $x+2=68+2$ = 70

Hence, the two numbers are 68 and 70.

So, the number of counties in state A are 70.

The number of counties in state B are 68.

What is the equation of the line described below written in slope-intercept form the line passing through the point (-1,5) and p

gregori [183]

The correct answer is y=-x+4

Further explanation:

Given equation of line is:

$x+y = 10$

Comparing it with the standard point-slope form

$y = mx+b$

We get

y = -x+10

m = -1

As the new line is parallel to given line it will also have m=-1 as slope of two parallel lines is equal

For finding b, we will put the point and value of m in standard form

$y = mx+b\\5 = (-1)(-1) + b\\5 = 1+b\\5-1 = b\\b=4$

Hence the equation will be:

$y = (-1)x+4\\y = -x+4$

The correct answer is y=-x+4

What is a difference of squares that has a factor of x-8? complete the expression: x2-

Ipatiy [6.2K]

Difference of two squares:

x² - y² = (x - y)(x + 8)

So for difference of squares that has (x -8) as one of the factor.

The other factor is (x + 8)

(x - 8)(x + 8) = x² - 8²

= x² - 64.

A student needs to make a square cardboard piece. The cardboard should have a perimeter equal to at least 92 inches. The functio

saveliy_v [14]

Answer: d. s ≥ 23

Step-by-step explanation:

Let s be the side of the square.

We know that the perimeter of a square =4s

Let f(s)=4s

If the cardboard should have a perimeter equal to at least 92 inches, the inequality would look like

$4s\geq 92$

Divide both sides by 4, we get

$s\geq\frac{92}{4}\\\Rightarrow\ s\geq23$

Thus, d. is the right answer. The reasonable domain of f(s) is $s\geq23$
