What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We are given that the equation – 2/3X – 1 = 4
Here, we need to solve for x,
– 2/3X – 1 = 4
Now combine the like terms;
– 2/3X = 4 + 1
-2/3x = 5
x = -15/2
Therefore, the solution will be as;
x = -15/2
The value of x will be; x = -15/2

which statement is true about the extreme value the given quadratic equation? y = -3x^2 + 12x - 33 Oa. The equation has a maximum value with a y coordinate of -27 Ob. The equation has a minimum value with a y coordinate of -21 Oc. the equation has a minimum value with a y coordinate of -27 Od. The equation has a maximum value with a y coordinate of -21
Answer:
D. The equation has a maximum value with a y coordinate of -21Step-by-step explanation:
The quadratic equation has the extreme value at vertex with x-coordinate of
x = -b/2aFor the given equation the vertex is:
x = -12/2(-3) = 2The value of y at x = 2 is:
y = -3(2²) + 12(2) - 33 = -12 + 24 - 33 = -21Since the leading coefficient is negative, the extreme is the maximum for the given equation.
Correct choice is D

Solve for x in the diagram below.
Answer:
x = 20
Step-by-step explanation:
The sum of the two angles is 90 degrees
x+3x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x+10-10 = 90-10
4x= 80
Divide each side by 4
4x/4 = 80/4
x = 20
Answer:
x = 20
Step-by-step explanation:
x and 3x + 10 form a right angle, then
x + 3x + 10 = 90
4x + 10 = 90 ( subtract 10 from both sides )
4x = 80 ( divide both sides by 4 )
x = 20

If you roll a single six-sided die, what is the probability of rolling an odd number?
A 1/6
B 1/3
C 1/2
D 3
Please help!
Answer: that means you have a 3/6 chance which can be simplified to 1/2
1, 3 and 5 are the odd numbers
Step-by-step explanation:
Answer:
the answer is c 1/2
Step-by-step explanation:
since there are 6 numbers on the die that range from 1-6, that means there are three odd numbers, so the probability would be 3/6, which can reduce to 1/2
Y= -6/5x-7 and y=2/5x+1
Answer:
x = -5
y = -1
Step-by-step explanation:
Y= -6/5x-7 and y=2/5x+1
then:
-6/5x - 7 = 2/5x + 1
simplify:
-8/5x = 8
divide both sides by 8:
-1/5x = 1
multiply both sides by 5:
-x = 5
x = -5
y = 2/5(-5) + 1 = -2 + 1 = -1

You want to buy 7 tickets at that same rate. Explain the mathematical process you used to determine the cost of 7 tickets. (Include the unit rate in your explanation)
Answer:
7x
Step-by-step explanation:
To purchase 7 tickets at the same rate ;
Mathematically, Total Cost of an item is :
Cost = unit price * quantity
Here,
quantity = 7 tickets
Since price per ticket(rate) is the same ; then we can take rate as x
Hence, the cost of the 7 tickets is :
Quantity * rate
7 * x = 7x

Step-by-step explanation:
A local shelter is having an Adopt-a-thon for kittens and puppies. Kittens cost $50 to adopt and puppies are $75. The shelter made $1200 during the Adopt-a-thon event and adopted off twice as many puppies as kittens. Write and solve a system to find how many puppies and kittens were adopted
Answer:
Step-by-step explanation:
P=2K
50K+75P=1200, using P from above makes this equation become
50K+75(2K)=1200
50K+150K=1200
200K=1200
K=6, since P=2K
P=2(6)=12
So 12 puppies and 6 kittens were adopted.
A relay race is 1/4 mile long and is run by 4-member teams. If each team member runs the same distance, what fraction of a mile does each team member run? Explain how you found your answer
Answer:
0.0625 miles
Step-by-step explanation:
There is a faster way but this way makes more sense
1/4 miles = 440 yards
440/4 (since 4 people)
110 yards per person
Put back into miles
Everyone ran 0.0625 miles

Determine the approximate average rate of change in the number of tickets sold between the 3rd and 10th days after the release.
OA.
OB.
The number of tickets sold changed at an average rate of approximately -20 tickets per day.
The number of tickets sold changed at an average rate of approximately – 7 tickets per day.
The number of tickets sold changed at an average rate of approximately –10 tickets per day.
The number of tickets sold changed at an average rate of approximately –3 tickets per day.
Ос.
D.
Answer:
-3 Is the average rate
Step-by-step explanation:
The number of tickets sold changed at an average rate of approximately -20 tickets per day. The correct answer is option A.
What is the average rate of change?The average rate of change is the average amount by which the function changed per unit throughout that time period. It is calculated using the slope of the line linking the interval's ends on the graph of the function.
The rate of change is calculated by the formula below:-
Rate of change = Final value - initial value.
From the given graph the value of tickets on the 3rd day is 100 and on the 10th day is 80. The final value of tickets is 80 and the initial value is 100.
The average rate of change in the number of tickets sold between the 3rd and 10th days after the release will be calculated as below:-
Rate of change = Final value - initial value.
Rate of change = 80 - 100
Rate of change = -20
Therefore, the number of tickets sold changed at an average rate of approximately -20 tickets per day. The correct answer is option A.

3x + 5 > 16
x is an integer.
Find the smallest value of x.
Answer:
4
Step-by-step explanation:
3x + 5 > 16
3x > 16 - 5
3x > 11
x > 11 / 3
x > 3.6666...
The smallest value would be 4.
Answer:
4
Step-by-step explanation:
Given
3x + 5 > 16 ( subtract 5 from both sides )
3x > 11 ( divide both sides by 3 )
x > [tex]\frac{11}{3}[/tex] , that is
x > 3 [tex]\frac{2}{3}[/tex]

Robert bought a pair of shoes that was on sale for 30% off
the original price of $79.95. Which is closest to the sale
price of the pair of shoes?
Answer:
The sale price of the shoes is $55.96
Step-by-step explanation:
1: 30% of $79.95 is 23.985.
Which would round to $23.99.
Then subtract 23.99 from 79.95.
79.95-23.99= 55.96

If 0 < f ≤ 90 and cos(22f − 1) = sin(7f + 4), what is the value of f?
f = 3
f = 4
f = 5
f = 6
Answer:
f=3
Step-by-step explanation:
The intervals means that angle f is between the quadrant 1.
Using that, we can use this identity
[tex] \sin(x) = \cos(y) [/tex]
where x+y=90
[tex]22f - 1 + 7f + 4 = 90[/tex]
[tex]29f + 3 = 90[/tex]
