Which sentences represent the inequality? check all that apply. 2.1 (-1.2x) greater-than-or-equal-to 8 the sum of 2.1 and –1.2 t

devlian [24]

The best interpretation is that the sum of 2.1 and –1.2 times a number is greater than or equal to 8.

<h3>Inequality functions</h3>

Inequality are expressions not separated by an equal sign, Given the inequality;

2.1 + (-1.2x) ≥ 8

The sign ≥ means greater than or equal to

The expression 2.1 + (-1.2x) ≥ 8 can also be expressed as 2.1 - 1.2x ≥ 8

The best interpretation is that the sum of 2.1 and –1.2 times a number is greater than or equal to 8.

63. What is the equation in point-slope form

viktelen [127]

Answer:

y-3=4(x-10)

Step-by-step explanation:

Point Slope Form: y-y1=m(x-x1)

Where m=slope and (x1, y1) is a point on the line.

m=(y2-y1)/(x2-x1)=(11-3)/(12-10)=8/2=4

So the slope is 4,

y-3=4(x-10)

The perimeter of the triangle is 41 inches. The perimeter of the rectangle is 66 inches.

Korolek [52]

Answer:

Part A) The system of equations is equal to

$41=4x+7y$

$33=(3x+7y)$

Part B)

The length is $24\ in$

The width is $9\ in$

Step-by-step explanation:

Part A)

we know that

The perimeter of the triangle is equal to the sum of the length of its three sides

In this problem

$41=x+3x+7y$

$41=4x+7y$ -----> equation A

The perimeter of rectangle is equal to

$P=2(L+W)$

In this problem

$66=2(3x+7y)$

$33=(3x+7y)$ ------> equation B

Part B)

Using a graphing tool

Solve the system of equations

We know that

The intersection point both graphs is the solution of the system of equations

$41=4x+7y$

$33=(3x+7y)$

The intersection point is $(8,9/7)$

see the attached figure

$x=8\ in$

$y=(9/7)\ in$

step 3

Find the length and width of the rectangle

The length is 3x

$3*8=24\ in$

The width is 7y

$7*(9/7)=9\ in$
