Answer: (-6,2)

-8 + (-4) / 2 = -6

-6 + 10 / 2 = 2

Answer:

M = (-6,2)

Step-by-step explanation:

To find a midpoint, you add the x-coordinates and divide by 2 to get the new x coordinate and then add the y-coordinates and divide by 2 to get the new y-coordinate.

(-8 + -4) /2 = x of M

(-6 + 10)/2 = y of M

M = (-6, 2)

Answer:

y=-3x-7

Step-by-step explanation:

the line is currently in standard form (ax+by=c). Let's put it into slope-intercept form (y=mx+b)

-x+3y=9

add x to both sides

3y=x+9

divide by 3

y=1/3x+3

perpendicular lines have slopes that when multiplied, equal -1.

to find the slope (m) of our new line:

1/3m=-1

multiply by 3

m=-3

the slope of the new line is -3

here's our equation so far:

y=-3x+b

we need to find b (y intecept)

since the line passes through the point (-3,2), it should be a solution in the equation (plug it in, and the result is a true statement). We can also use it to find b

so, substitute the pointt into the equation:

2=-3(-3)+b

multiply

2=9+b

subtract

-7=b

so the equation of the line is y=-3x-7

Answer:

[tex]7w+5s\leq 400[/tex]

Step-by-step explanation:

Money to be spent is not more than $400.

Cost of a case of water = $7

Cost of each sandwich = $5

Let number of cases of water bought be [tex]w[/tex]

Number of sandwiches bought be [tex]s[/tex]

From the question we get

[tex]7w+5s\leq 400[/tex]

The inequality which would determine how many sandwiches, and how many cases of water that can be bought is [tex]7w+5s\leq 400[/tex].

Answer:

78.5 yards

Step-by-step explanation:

Essentially, to find the area of a circle simply use the equation pi r^2 (r=radius, or half of diameter). They also make it really easy by saying we may use 3.14 for pi, so really, we simply have to solve:

Step-by-step explanation:

the quotient is the result you get from division

Answer:2x+15+6x-37/2=3x+5

We move all terms to the left:

2x+15+6x-37/2-(3x+5)=0

We add all the numbers together, and all the variables

8x-(3x+5)+15-37/2=0

We get rid of parentheses

8x-3x-5+15-37/2=0

We multiply all the terms by the denominator

8x*2-3x*2-37-5*2+15*2=0

We add all the numbers together, and all the variables

8x*2-3x*2-17=0

Wy multiply elements

16x-6x-17=0

We add all the numbers together, and all the variables

10x-17=0

We move all terms containing x to the left, all other terms to the right

10x=17

x=17/10

x=1+7/10

The value of RS is 31.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

If RS and UT are parallel, then their corresponding sides are proportional. Thus,

RS/UT = (2x + 15)/(6x - 37)

Now,

RS/UT = (2x + 15)/(6x - 37)

Cross-multiplying.

(2x + 15)UT = RS(6x - 37)

Expanding and simplifying.

2xUT + 15UT = 6xRS - 37RS

Rearranging.

6xRS - 2xUT = 15UT + 37RS

Factorizing.

2x(3RS - UT) = 15UT + 37RS

Dividing both sides by (3RS - UT):

2x = (15UT + 37RS)/(3RS - UT)

Substituting RS = 2x + 15 and UT = 6x - 37:

2x = (15(6x - 37) + 37(2x + 15))/(3(2x + 15) - (6x - 37))

Simplifying

2x = (90x - 555 + 74x + 555)/(6x + 36)

2x = (164x)/(6x + 36)

Multiplying both sides by (6x + 36):

12x² + 72x = 164x

Simplifying

12x² - 92x = 0

Factoring out 4x.

4x(3x - 23) = 0

So,

x = 0 or x = 23/3.

Since x cannot be 0 (as it would make UT = -37, (which is not possible),

x = 23/3.

Substituting this value of x into RS = 2x + 15.

RS = 2(23/3) + 15 = 31

Thus,

The value of RS is 31.

Step-by-step explanation:

You want to calculate the interest on $2730 at 4.2% interest per year after 5,000 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:P is the principal amount, $2730.00.

r is the interest rate, 4.2% per year, or in decimal form, 4.2/100=0.042.

t is the time involved, 5....year(s) time periods.

So, t is 5....year time periods.

To find the simple interest, we multiply 2730 × 0.042 × 5 to get that:

The interest is: $573.30
