Find the distance between the points (-10, -2) and (-8,0).

*round to the nearest tenth

The fraction expression (17)/(2)g - (9)/(2)h is not the same as (9)/(2)h-(17)/(2)g.

We are given the fraction expression;

(17/2)g - (9/2)h

Now, the fraction (17/2) is greater than (9/2) and as such the result of the subtraction of the fractions will be positive.

Now, if we change the order of the subtraction to be;

(9/2)h - (17/2)g

This means that the result will now be negative since (9/2) is less than (17/2).

Thus, we can conclude that the expression (17)/(2)g - (9)/(2)h is not the same as (9)/(2)h-(17)/(2)g.

The solution for the inequality | x | + 9 ≤ 7 is (option d) x ≤ -2 and x > -16

You can solve an inequality by: adding the same amount to each side; taking the same amount away from each side; multiplying or dividing each side by the same positive amount. The inequality symbol needs to be turned around if either side is multiplied or divided by a negative number. Therefore, the answer is x > 1.

Given,

The expression:   | x | + 9 ≤ 7

If | x | ≤ a ⇒ -a ≤ x ≤ a

Then,

-7 ≤ | x | + 9 ≤ 7

⇒ -7 - 9 ≤ x ≤ 7 - 9

⇒ -16 ≤ x ≤ -2

That is x ≤ -2 and x > -16.

Answer:

[tex] \sf \fbox{46.296 British Pounds}[/tex]

Step-by-step explanation:

1 shower job requires 3 hours of work,

plumber will fix only 1 shower that means he will work for 3 hours,

Charges of 1 hour = 25$

Charges of 3 hour = 25× 3 = 75$

The currency that plumber accept is British pound (£),

1 British pound (£) = 1.62 dollar ($)

x British pound = 75 dollar

[tex] \frac{1}{x} = \frac{1.62}{75} [/tex]

taking reciprocal both the side,

[tex] \frac{x \cancel £}{1\cancel£} = \frac{75 \: \cancel\$ }{1.62 \:\cancel \$} [/tex]

[tex]x = 46.296[/tex]

Jamar need to pay 46.296 British Pounds to plumber for the shower job.

The two units that were cancelled was Dollar & Pound.

It is required to cancel units because, mathematical operation does not work for different units. For e.g. If I have given two measurement one is volume(cm³) & another is length(cm) so I cannot add them.

She will need 5 3/5 cups of cranberry juice to make a punch for the school if Molly uses 1 2/5 quarts of lemonade.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

To make the recipe,

3/4 quart of lemonade and 3 cups of cranberry juice

The ratio of cranberry juice to a quart of lemonade

⇒ 3/(3/4) = 4

To make the same recipe with 1(2/5) quarts of lemonade the ratio of cranberry juice to a quart of lemonade must be maintained.

So,

4 = cranberry juice / 1(2/5)

(5/7) × cranberry juice = 4

Cranberry juice = 28/5 ⇒ 5 (3/5).

Hence "She will need 5 3/5 cups of cranberry juice to make a punch for the school if Molly uses 1 2/5 quarts of lemonade".

The arrow is in -7 on the number line since 3 + (-10) = -7.

A number line is a pictorial representation of numbers on a straight line.

It is a horizontal line that has equally spread number increments.

We have,

3 + (-10)

This can be written as:

= 3 - 10

= -7

We can draw a number line to represent graphically:

Answer:

The values of x for the equation 5x² - 9x - 10 is x = 9 ± √(281) / 10.  

Step-by-step explanation:

In this question we need to solve the given equation that is 5x² - 9x - 10 to obtain the value of x using the complex solution method.

Now, the given equation is 5x² - 9x - 10 in which we need to apply the quadratic formula to find the solution;

So, the quadratic formula is => -b ± √(b² - 4ac) / 2a

Now, on comparing the equation 5x² - 9x - 10 we get the values;

a = 5

b = -9

c = -10

Further, on substituting the values given above in the quadratic formula to obtain the value of x.

=> -(-9) ± √((-9)² - 4(5×(-10)) / 2×5

=> 9 ± √(81 +200) / 10

=> 9 ± √(281) / 10

After simplifying the above equation we obtained the value of x that is;

=> x = 9 ± √(281) / 10

Now, the final values of x from the above condition are;

=> x = 9 + √(281) / 10  

and

=> x = 9 - √(281) / 10

It can be further represented in the decimal form;

=> x = 2.57630546...

and

=> x =  −0.77630546...

Thus, the values of x for the equation 5x² - 9x - 10 is x = 9 ± √(281) / 10.

[tex] \sf \: x=0.4[/tex]

Step-by-step explanation:

-0.5x-3.69=x-1.9-2.39

Step 1: Simplify both sides of the equation.

−0.5x−3.69=x−1.9−2.39

−0.5x+−3.69=x+−1.9+−2.39

−0.5x−3.69=(x)+(−1.9+−2.39)(Combine Like Terms)

−0.5x−3.69=x+−4.29

−0.5x−3.69=x−4.29

Step 2: Subtract x from both sides.

−0.5x−3.69−x=x−4.29−x

−1.5x−3.69=−4.29

Step 3: Add 3.69 to both sides.

−1.5x−3.69+3.69=−4.29+3.69

−1.5x=−0.6

Step 4: Divide both sides by -1.5.

−1.5x/−1.5 = −0.6/−1.5

x=0.4

The value of x will be 0.4.

In mathematics, an equation is a connection of two expressions that is expressed as an equality on all sides of the corresponding sign.  A statement that uses the equal sign to show that both of the expressions possess the same value is called an equation. Mathematical equations are made up of figures, an equal sign, and an optional variable in the position of an unknowable value.

-0.5x-3.69=x-1.9-2.39

-0.5x - x = -1.9 - 2.39+3.69

There are 4 types of translation they are, translation, rotation, and dilation.

We know when we rotate a shape 270° counter-clockwise the coordinates (x,y) becomes (y, -x) that is we switch x and y and make x negative.

Given a parallelogram with points C(-4,6), D(-7,2), E(6,6) and F(3,2).
