Solve the equation.
–2x – 18 = 6
A. -12
B. -3
C. -2
D. 6
Answer:
-12
Step-by-step explanation:
Step 1: Add 18 to both sides.
−2x−18+18=6+18
−2x=24
Step 2: Divide both sides by -2.
−2x
−2
=
24

x=-12
Answer:
-2x -18=6
+18. +18
-2x=24
÷-2. ÷-2
×= -12
Who can answer my question in square LMNO find the length of LM
Answer:
10 units
Step-by-step explanation:
LMNO is a square.
All sides of square are equal
MN = LM
3x + 1 = x + 7
3x - x = 7 - 1
2x = 6
x = 6/2
x = 3
LM = x + 7 = 3 + 7 = 10
LM = 10 units

Step-by-step explanation:
A jar contains 42 red marbles numbered 1 to 42 and 36 blue marbles numbered 1 to 36. A marble is drawn at random from the jar. Find the probability of the given event. Please enter reduced fractions. (a) The marble is red. P(red)= Correct (b) The marble is odd-numbered. P(odd)= Correct (c) The marble is red or odd-numbered. P(red or odd) = Incorrect (d) The marble is blue or even-numbered. P(blue or even) =
Answer: See explanation
Step-by-step explanation:
Number of red marbles = 42
Number of blue marbles = 36
Total number of marbles = 42 + 36 = 78
There are 21 odd numbers between 1 - 42.
There are 18 odd numbers between 1 - 36.
(a) Probability that the marble is red will be:
P(red)= 42 / 78 = 7 / 13
(b) Probability that the marble is odd-numbered will be:
= 39 / 78 = 1/2
(c) Probability that the marble is red or odd-numbered will be:
P(red or odd) = P(red) + p(odd) - P(odd and red)
= (42/78) + (39/78) - (21/78)
= 60/78
= 10/13
(d) Probability that the marble is blue or even-numbered.
= P(blue) + P(even) - P(blue and even)
= 36/78 + 39/78 - 18/78
= 57/78
= 19/26
Choose the graph below that correctly represents the equation 3x + 9y = −18. (5 points)
the line through the points negative 6 comma 0 and 0 comma 2
the line through the points negative 6 comma 0 and 0 comma negative 2
the line through the points negative 2 comma 0 and 0 comma 6
the line through the points negative 2 comma 0 and 0 comma negative 6
Answer:
the line through the points negative 6 comma 0 and 0 comma negative 2
Step-by-step explanation:
Rewrite the equation to something you are familiar with such as the slope intercept form; y = mx + b. This means you need to solve for y.
3x + 9y = -18 --- divide everything by 3.
x + 3y = -6
3y = -6 - x
y = -2 - 1/3x
your slope is -1/3 and your y intercept is - 2.
remember, y-intercept is when x = 0. therefore, when x = 0, y = -2.
write as an ordered pair (0, -2). the only option that has (0, -2) is the second one.
Therefore, the line through the points negative 6 comma 0 and 0 comma negative 2.
13. A quadratic function passes through the points (0,5), (2,3), and (3,5). Which

C h(c) = -3x2++5
D h(c) = x2
= 2 + 5x - 3

Find the unit rate
a. 5 movie tickets for $25.00
b. mowed 5 yards for $35.00
c. 6 calculators cost $240.00
d. 8 dollars for 2 cans of tuna
Answer:
A. $5
B. $7
C. $40
D. $4
Step-by-step explanation:
To find the unit rate, you need to divide the cost by the amount.
A. $25/5 = $5 for a movie ticket
B. $35/5 = $7 for one yard
C. $240/6 = $40 for a calculator
D. $8/2 = $4 for a can of tuna
I need help answering that I’m lost and it’s a 3 step problem
Does anyone know this? Please and ty! This is worth 15 points but please don’t take advantage :(
Answer:
A
Step-by-step explanation:
If you were to dilate a point by a scale factor of 2, then if you have the point (-4,0), both the x value and the y value would be multiplied by 2, giving a coordinate of (-8,0). If you do this to the other point, you get (0,4).
Now graph it out, and you get a parallel line that is not right on top, eliminating answer B. It's not C because it is parallel, not intersecting. And it's not D because they are related, they're parallel.
Hope this helps!
