6(x-2.5) ≥ 8-6(3.5+x)

A number is before a parenthesis. The first step is to multiply.

6(x-2.5) = 6x -15

8-6(3.5+x)
2(3.5+x)= 7+2x

6x-15≥7+2x

Now solve

6x-15≥7+2x
-2x -2x

(-2x+2x)= They cancel out

(6x-2x)= 4x

4x-15≥7
+15 +15

4x≥22
/4 /4

You get= x≥5.5

The sum of squares of numbers is: 13

Step-by-step explanation:

Let x and y be two numbers

Then,

Difference of the squares of the numbers will be:

$x^2-y^2$

Product will be:

$xy$

Given identity is:

$(x^2+y^2)^2=(x^2-y^2)^2+(2xy)^2$

Given values are:

Difference of the squares of the numbers= $x^2-y^2=5$

Product of numbers = xy = 6

Putting the values in the identity

$(x^2+y^2)^2=(5)^2+[2(6)]^2\\=25+(12)^2\\=25+144\\=169$

As we have to only find x^2+y^2

Taking square root on both sides

$\sqrt{(x^2+y^2)^2}=\sqrt{169}\\x^2+y^2=13$

The sum of squares of numbers is: 13

Write the equation of the line that has a slope of -2 and goes through the point (-3,4).

liubo4ka [24]

<u>SOLUTION:</u>

General Equation: y = mx + b

Substitute slope = -2 into the equation:

y = -2x + b

Find the y-intercept:

4 = -2(-3) + b

4 = 6 + b

b = -2

Substitute b = -2 into the equation:

y = -2x - 2

Answer: y = -2x - 2

Find the cost per visit to the nearest cent: Health and Heart Club, $259 per year, 3 visits per week. a. $1.66 b. $7.19 c. $156

vagabundo [1.1K]

Answer:

a. $1.66

Step-by-step explanation:

We have been given that Health and Heart Club charges $259 per year. A person has 3 visits per week. We are asked to find the cost of per visit to Health and Heart Club.

We know that there are 52 weeks in one year. So total visits in one year would be 3 times 52 that $156$ visits.

Now, we will divide total cost by 156 to find cost per visit.

$\text{Cost per visit}=\frac{\$259}{156}$

$\text{Cost per visit}=\$1.660256$

Rounding to nearest hundredths, we will get:

$\text{Cost per visit}\approx \$1.66$

Therefore, the cost per visit is $1.66 and option 'a' is the correct choice.
