Answers
Answer:
Let P(–2, 5) and Q(–5, 9).
The component form of Vector P Q is – 3, 4
The magnitude of Vector P Q is 5
To the nearest degree, the direction angle of Vector P Q is 127º
If Vector P Q is multiplied by the scalar –10, the new vector will be in the opposite direction but longer than the original vector.

Which systems of equations intersect at point A in this graph?
Answers
Answer:
The point of intersection of the system of equations is:
(x, y) = (-2, 1)
The correct system of equations intersect at point A in this graph will be:
[tex]\begin{bmatrix}y=4x+9\\ y=-3x-5\end{bmatrix}[/tex]
Thus, the second option is correct.
Step-by-step explanation:
Given the point
A (-2, 1)Let us check the system of equations to determine whether it intersect at point A in this graph.
Given the system of equations
[tex]\begin{bmatrix}y=4x+9\\ y=-3x-5\end{bmatrix}[/tex]
Arrange equation variable for elimination
[tex]\begin{bmatrix}y-4x=9\\ y+3x=-5\end{bmatrix}[/tex]
so
[tex]y+3x=-5[/tex]
[tex]-[/tex]
[tex]\underline{y-4x=9}[/tex]
[tex]7x=-14[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}y-4x=9\\ 7x=-14\end{bmatrix}[/tex]
Solve 7x = -14 for x
[tex]7x=-14[/tex]
Divide both sides by 7
[tex]\frac{7x}{7}=\frac{-14}{7}[/tex]
Simplify
[tex]x = -2[/tex]
For y - 4x = 9 plug in x = 2
[tex]y-4\left(-2\right)=9[/tex]
[tex]y+4\cdot \:2=9[/tex]
[tex]y+8=9[/tex]
Subtract 8 from both sides
[tex]y+8-8=9-8[/tex]
Simplify
y = 1
Thus, the solution to the system of equations is:
(x, y) = (-2, 1)
From the attached graph, it is also clear that the system of equations intersects at point x = -2, and y = 1.
In other words, the point of intersection of the system of equations is:
(x, y) = (-2, 1)
Therefore, the correct system of equations intersect at point A in this graph will be:
[tex]\begin{bmatrix}y=4x+9\\ y=-3x-5\end{bmatrix}[/tex]
Thus, the second option is correct.
Help me do 1/6+1/4 make sure the demonator is the same
Answers
______________________________
1.) Find the LCF of 6 and 4: [tex]6,4=12[/tex]
- We do this because in order to add these, they must have the same denominator. So you must find the LCF, (Least Common Factor) of 6 and 4.
2.) Convert the fractions to have the same denominator: [tex]\frac{1}{6}=\frac{2}{12}[/tex] [tex]\frac{1}{4}=\frac{3}{12}[/tex]
- [tex]\frac{1}{6}[/tex] changes to [tex]\frac{2}{12}[/tex] by multiplying the numerator and denominator by 2. And [tex]\frac{1}{4}[/tex] changes to [tex]\frac{3}{12}[/tex] because you multiply the numerator and denominator by 3.
3.) Add the numerators: [tex]2+3=5[/tex]
- Since both fractions have the same denominator all you have to do is add the numerators together.

Solve each compound inequality. Graph your solutions.

Answers
Answer:
Solving the inequality [tex]5 + m > 4\: or\: 7m< -35[/tex] we get [tex]\mathbf{m>-1\:or\: \:m<-5}[/tex]
The graph of the inequality is shown in figure attached.
Step-by-step explanation:
We need to Solve each compound inequality [tex]5 + m > 4\: or\: 7m< -35[/tex]
Solving the inequalities
For solving compound inequalities we solve both inequalities simultaneously and find the value of m.
For solving 5+m > 4, we subtract 5 from both sides.
While solving 7m < -35, we divide both sides by 7 to get value of m
Applying these functions we get:
[tex]5 + m > 4\: or\: 7m< -35\\m>4-5\:or\:m<\frac{-35}{7}\\m>-1\:or\:m<-5[/tex]
So, solving the inequality [tex]5 + m > 4\: or\: 7m< -35[/tex] we get [tex]\mathbf{m>-1\:or\: \:m<-5}[/tex]
The graph of the inequality is shown in figure attached.

Answers
Answer:
No, Brandon is not correct in making that statement
Step-by-step explanation:
No, Brandon is not correct in making that statement. The absolute value of a number is the total distance between that number and 0. Brandon most likely states this because the absolute value of a negative number such as -5 would actually be the opposite, which is 5. This is not true for the absolute value of a positive such as 5, which instead is actually just 5. Meaning that the absolute value of a positive integer is the same value and NOT the opposite.

-1 < x ≤ 3 (Divide -5 on both sides)

Answer:
[tex]-1<x\leq3[/tex]
Step-by-step explanation:
Let's take two equations from this and them put them back together! So:
9>-5x+4
and
[tex]-5x+4\geq -11[/tex]
For the first one:
9>-5x+4
Subtract 4 from both sides
5>-5x
Then divide by -5 (Remember to change the direction of the sign!):
-1<x
Now onto the second one:
[tex]-5x+4\geq -11[/tex]
Subtract 4 from both sides:a
[tex]-5x\geq -15[/tex]
Then divide by -5 (Remember to change the direction of the sign!):
[tex]x\leq 3[/tex]
Now add the equations back together:
[tex]-1<x\leq3[/tex]

Answer:
56π
Step-by-step explanation:
1. Approach
To find the radius of a circle, use the formula;
[tex]A = r^{2}[/tex]π
To find the area of the shaded region, find the area of the larger circle, and then subtract the area of the smaller circle from it.
It is given that the larger circle has a radius of 9, and the smaller has a radius of 5.
2. Area of the larger circle
[tex]A = r^{2}[/tex]π
Substitute in known value (use 3.14 for π)
[tex]A = (9)^{2} * 3.14[/tex]
A = 254.47
3. Area of the smaller circle
[tex]A = r^{2}[/tex]π
Substitute in known value (use 3.14 for π)
[tex]A = (5)^{2} * 3.14[/tex]
A = 78.54
4. Area of the shaded region
Subtract the area of the smaller circle from the area of the larger circle;
254.47 - 78.54 = 175.93

- The new apartment you ałe about to sign a one-year lease on is $1,500 per month. The lease
requires you to put up first month's rent and a $750 security deposit to move in. In addition,
keeping your cat will cost an additional $300 for a pet deposit. How much do you need to write a
check for to the landlord at the time of move in?
Answers
Answer:
Total amount = $2550
Step-by-step explanation:
To move in the apartment payments to be done,
1). First month rent = $1500
2). Security deposit = $750
3). Pet deposit = $300
Total payment to be done = 1500 + 750 + 300
= $2550
Therefore, total amount to be paid = $2550
I will write a check of $2550.
