Find the distance between (-3,-11) and (8,-42)
Answer:
√2930
Step-by-step explanation:
The distance formula is
√((difference between x values)² + (difference between y values)²)
= √((-3 - 8)² + (-11 - (-42))²)
= √((-11)² + (31)²)
= √1082

[tex]-\frac{43}{70}[/tex]
Step-by-step explanation:
One is given the following equation,
[tex]\frac{2}{3}*\frac{-3}{7}-\frac{1}{14}-\frac{3}{7}*\frac{3}{5}[/tex]
Simplify, use the order of operations. The order of operations is a sequence by which one must simplify an equation. This sequence is the following,
1. Parehtensis
2. Exponents
3. Mutliplcaiton or Division
4. Addition or subtraction
Simplify the given expression. Remember, when multiplying fractions, one must cancel out like terms or factors that can be found in both the numerator and denominator,
[tex]\frac{2}{3}*\frac{-3}{7}-\frac{1}{14}-\frac{3}{7}*\frac{3}{5}[/tex]
[tex]\frac{-2}{7}-\frac{1}{14}-\frac{3}{7}*\frac{3}{5}[/tex]
[tex]\frac{-2}{7}-\frac{1}{14}-\frac{9}{35}[/tex]
Convert to the least common denominator. In this case, the least common denominator is (70). Remember to multiply both the numerator (number over the fraction bar) and denominator (number beneath the fraction bar) to convert the denominator.
[tex]\frac{-2}{7}-\frac{1}{14}-\frac{9}{35}[/tex]
[tex]\frac{-2}{7}*\frac{10}{10}-\frac{1}{14}*\frac{5}{5}-\frac{9}{35}*\frac{2}{2}[/tex]
Simplify,
[tex]\frac{-2}{7}*\frac{10}{10}-\frac{1}{14}*\frac{5}{5}-\frac{9}{35}*\frac{2}{2}[/tex]
[tex]\frac{-20}{70}-\frac{5}{70}-\frac{18}{70}[/tex]

Answer:
1
Step-by-step explanation:
You can put either number in the form of the other to see they are equal. A number divided by itself gives a quotient of 1.
-1 1/10 = -(10·1 +1)/10 = -11/10 . . . . . matches the denominator
or
-11/10 = -1 1/10 . . . . . matches the numerator
__
(-11/10)/(-11/10) = 1 . . . . your quotient
_____
Additional comment
Here, we see that both numbers in the problem are negative, so we have an even number of minus signs. That means the quotient will be positive. Knowing this lets us eliminate the minus signs from the problem.
As you may know, there are a couple of (fully equivalent) ways to divide fractions.
1) "invert and multiply" or "dot swap"
(11/10) ÷ (11/10) = (11/10) · (10/11) . . . . . . . the denominator has been inverted
= (11·10)/(10·11) = 110/110 = 1
2) use the numerators when the denominators are equal.
(11/10) / (11/10) = 11/11 = 1 . . . . denominators of the fractions are both 10
Simplify the expression
by combining like terms.

The perimeters of the two rectangles at right are equal. Write and solve an equation to find the value of x and the common perimeter. (desperate need of help)
Answer:
write the expression for the perimeter of the 1st rectangle 6x
write the expression for the perimeter of the 2nd rectangle 4x + 30
write the equation 6x = 4x + 30
x= 15
perimeter = 90
Step-by-step explanation:
The perimeter is adding up all the sides of the rectangle.
So for the first one, we know two of the sides: x and 2x. The opposite sides have the same values. So the other two sides are x and 2x.
Therefore, the perimeter is
2x + x + 2x + x
or
6x
Similarly with the second rectangles:
(x+12) + (x+3) + (x+12) + (x+3)
Combine like terms
x + x + x + x + 12 + 3 + 12 + 3
4x + 30
Set these two equal to each other because the two perimeters are equal
6x = 4x + 30
Subtract 4x on both sides
2x = 30
Divide by 2 on both sides
x = 15
Check:
6(15) = 4(15) + 30
90 = 60 + 30
90 = 90
The common perimeter is
6*15 = 90 units

93,487,991 to the nearest hundred thousand
Answer:
93,500,000
Step-by-step explanation:
Rounding rule:
1) If the digit directly next to the one you are finding is 5 or greater, round up.
2) If the digit is 4 or less, round down.
Note the hundred thousands place value (underlined and bolded):
93,487,991
Look at the digit value directly next to the place value you are looking for. The value of the digit is 8. Because 8 is greater then 5, round up:
93,487,991 rounded to the nearest hundred thousand is 93,500,000.

can anyone help me solve this function please?
Answer:
f(-5) = 19
Step-by-step explanation:
f(t) = -3t+4
Let f(t) = 19
19 = -3t+4
Subtract 4 from each side
19 - 4 =-3t+4-4
15 = -3t
Divide each side by -3
15/-3 = -3t/-3
-5 = t
Answer:
the answer is -5
Step-by-step explanation:
F(t)=-3(t)+4
it told you that F(t) is equal to 19
so -3*-5=15+4=19

Due today:
At a local car dealer, the ideal selling price of a car is $22,000. The dealer allows this price to vary $1200 .
Create an absolute value inequality that models the range of the price the dealer can sell the car. (Hint: Test your inequality to make sure the price is $1200 below and above the selling price works.)
We know that:
The ideal selling price is P = $22,000
The price can vary dP = $1,200
let's define p as the variable that represents the possible prices of the car.
We will find that the absolute value equation that represents this is:
|p - $22,000| ≤ $1,200
Now let's see how we get that, using the initial information we can get:
The minimum price can be:
mP = P - dP = $22,000 - $1,200 = $20,800
The maximum price can be:
MP = P + dP = $22,000 + $1,200 = $23,200
Then the range of allowed prices is:
mP ≤ p ≤ MP
$20,800 ≤ p ≤ $23,200
To write this as an absolute value equation, we use the general formula:
Ix - average| ≤ amount that it can vary
Replacing it with our values we get:
|p - P| ≤ dP
|p - $22,000| ≤ $1,200
Concluding, the absolute value equation that we wanted to find is:
|p - $22,000| ≤ $1,200
