Answer:
x > -22/7
Step-by-step explanation:
To find out which inequality is is equivalent, you solve for x.
-4(x+7) < 3(x-2): distribute variables
-4x-28 < 3x-6: Add 6 to both sided
-4x-22 < 3x: add 4x to both sides
-22 < 7x: divide by 7
-22/7 < x: you can switch sides if prefered but you have to switch sign too
x > -22/7

What is an equation of the line that passes through the point
(-6, – 7) and is perpendicular to the line 6x + 5y = 30?
HELP!!!
Answer:
(y+7)=5/6(x+6)
Step-by-step explanation:
For this problem we need to use Point-Slope Form to write an equation.
We already have the point, (-6,-7), so all we need now is the slope, which we know is perpendicular to the line 6x+5y=30.
First, let's find the slope of 6x+5y=30 by converting it into Slope-Intercept Form, which is y=mx+b. m is the slope.
6x+5y=30
5y=-6x+30
y=-6/5x+6
So the slope of this line is -6/5, but we need the slope of the line is perpendicular to this line.
When a line is perpendicular to another, their slopes are negative reciprocals to one another, or opposite reciprocals. For example, a line that is perpendicular to another line that has a slope of 3/4 will have a slope of -4/3. Flip the numerator and denominator to find the reciprocal and add a negative.
x
So the negative reciprocal of -6/5 is 5/6, so that is our slope.
Now we can assemble our equation, here is the Point-Slope Form:
[tex](y -y_{1}) =m(x-x_{1})[/tex]
again, m is our slope.
[tex]y_{1}[/tex] and [tex]x_{1}[/tex] represent the coordinates of the point that this line passes through, (-6, -7).
Let's plug in the y, x, and m values:
(y-(-7))=5/6(x-(-6))
Simplify:
(y+7)=5/6(x+6)
That is our final answer.

select the construction that guaranties A is a reflection of point A across line BC
Answer:
I think it's Axial Symmetry.
Step-by-step explanation:
You draw a perpendicular line to the line BC through A.You get your compass and set it to the distance between the point A and the line BC. Using that distance on your compass, put the point of your compass on the point where the perpendicular line and BC intersect. Mark the distance on the perpendicular line. The reflection is the point you mark on the perpendicular line.1. Point M is on PQ, PM has a length of 7 units, and point N is the midpoint of MQ. If the length of NQ
is 4 units, how long is PQ?
PA
A 3 units
B. 11 units
C. 15 units
D. 18 units
Answer:
C. 15 units
Step-by-step explanation:
PM = 7 units
p..............M..........N............Q
7 unit 4 unit
NQ = 4 units
Given that
N is midpoint of MQ
it means N divides MQ into two equal parts
thus
MN = NQ = 4 units
now
we have to find length of PQ
p..............M..........N............Q
7 unit 4 units 4 unit
PQ = PM + MN + NQ
PQ = 7 units + 4 units + 4 units = 15 units
thus, correct answer is option c 15 units
Answer:
15 units

Alice and Bob are playing the Smallest Positive Integer Game. Alice says, "My number is 24." Bob says, "What kind of silly smallest number is that? Every prime factor of your number is also a prime factor of my number." What is the smallest possible number that Bob could have?
Answer:
6
Step-by-step explanation:
Alcumus Explanation: The prime factorization of 24 is 2^3 times 3, so 2 and 3 have to be prime factors of Bob's number as well. The smallest possible number is when each the exponents of both of them is 1, giving 2 times 3= 6.

What is the equation in slope-intercept form of the line that passes through the points ( -4, 47) and ( 2 , -16)?
ANSWER CHOICES BELOW...ANSWER CORRECTLY PLZ TAKING INTERIM NOW
Answer:
C
Step-by-step explanation:
Slope intercept form equation is y=mx+b
M=Slope
Slope equation is y2-y1 over x2-x1
So -16 - 47 over 2- (-4)
-63 over 6
Divide by 3 to simplify
= -21 over 2
Keep that as your answer for slope because a mixed number can't be used for slope but an improper fraction is perfectly fine
To find b use one point given (I chose to use (2, -16)
Plug that in and your slope to find b
-16= -21/2 (2) +b
-16= -21+b
+21 +21
5=b
Now plug that in and youre done
Y= -21/2x + 5

Ms. Harris goes on a road trip with her fellow colleagues for spring break. 10 points
Ms. Harris is trying to estimate how much gas it will to drive 600 miles.
Ms. Harris's car typically gets 29 miles per gallon of gas. How many
gallons will Ms. Harris need to complete her 600 miles of travel.
O 20 gallons
O 19 gallons
O 21 gallons
O 22 gallons
Answer:
21 gallons
Step-by-step explanation:
600 = 29g
600/29 = g
20.689 = g
Round up
21 = g
Answer:
21 gallons
Step-by-step explanation:when you do 600/29 you get 20.68 if you round that up you get 21
Which formula represents this sequence 2,8,14...?
Answer:
[tex]a_{n}[/tex] = 6n - 4
Step-by-step explanation:
There is a common difference between consecutive terms in the sequence, that is
8 - 2 = 14 - 8 = 6
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = 6 , thus
[tex]a_{n}[/tex] = 2 + 6(n - 1) = 2 + 6n - 6 = 6n - 4
Thus the formula representing the sequence is
[tex]a_{n}[/tex] = 6n - 4
30 = -5(6n + 6) how do I show my WORK????
Answer:
- 2
Step-by-step explanation:
Step 1:
30 = - 5 ( 6n + 6 ) Equation
Step 2:
30 = - 30n - 30 Multiply
Step 3:
60 = - 30n Add 30 on both sides
Step 4:
n = 60 ÷ - 30 Divide
Answer:
n = - 2

I have 40 softballs i give 5 softballs to each player. How many players can i give softballs to so that i have at most 10 softballs left
Answer:
6
Step-by-step explanation:
5 to each players means you have 6 players and then you have 10 left for yourself
Answer:
You can hand out 5 softballs to 6 players.
Step-by-step explanation:
In order to solve this problem, you need to divide 30 balls to each player (In order to have 10 left.) 30 divided by 5 is 6, so you can only hand out 5 balls to 6 players in order to have 10 left out of 40.

There are 15 questions, and John got an 84% on the quiz, how many questions did John get right and how many wrong?
Answer:
John got 13 questions right and 2 questions wrong.
Step-by-step explanation:
15 questions right equals 100%.
100 {divided by} 15 = % for each question right
Each question is worth (100 diveded by 15) 6.7%.
84% {diveded by} 6.7% = 12.5
100% - 84% = 16%
16% {divided by} 6.7% = 2.38
Because 12.5 has a higher dicimle value than 2.38 and when the amount he got right is added to the amount he got wrong it needs to equal 15, 12.5 becomes 13 and 2.38 becomes 2.
Answer:
[tex]\frac{n}{15} =\frac{84}{100}[/tex]
[tex]n = \frac{21}{25}*5[/tex]
[tex]n = \frac{21*15}{25}[/tex]
[tex]n = \frac{315}{25}[/tex]
[tex]n = \frac{63}{5} or 12.6[/tex]

Find the Unit Rate on a 5-gallon bucket of paint that costs $68.75
Answer:
$13.75 per gallon
Step-by-step explanation:
To solve for any unit rate you use
[tex]\frac{1}{x} =\frac{5}{68.75}[/tex]
Cross multiply.
So 68.75 = 5x
Divide both sides by 5 to get x alone.
13.75 = x
Therefore 1 gallon equals $13.75

Answer:
(-4,3)
Step-by-step explanation:
Answer:
P = -4, 3
Step-by-step explanation:
Locate the x-axis (horizontal) location of point P, starting from zero
Point P's x-axis = -4
Now locate the y-axis (vertical) location of point P, starting from zero
Point P's y-axis = 3
Combine the two axes in a coordinate equation.
Point P = (-4, 3)
Note that zero is located at the intersection of the two axes.
