If h(x) = −2x − 10, find h(−4). −2 −18 −3 −16
Answer:
The correct option is (a) i.e.
h(-4) = -2
Step-by-step explanation:
The mathematical expression is given as :
[tex]h(x)=-2x-10[/tex]......(1)
Where
h(x) is dependent on x
We need to find the value of h(x) at x = -4 . Putting the value of x in equation (1) we get :
[tex]h(-4)=-2(-4)-10[/tex]
[tex]h(-4)=8-10[/tex]
h(-4) = -2
The value of h(-4) is -2. So, the correct option is (a). Hence, this is the required solution.

what is 2 1/2 divided by 1/3
The value of the 2¹/₂ divided by 1/3 is equal to 15/2, or 7¹/₂
What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.
So, we can rewrite the expression as:
2¹/₃ ÷ 1/3 = (5/2) ÷ (1/3)
Now, we multiply the first fraction by the reciprocal of the second fraction:
(5/2) ÷ (1/3) = (5/2) × (3/1)
Multiplying the numerators and denominators, we get:
(5 × 3) ÷ (2 × 1) = 15/2
Therefore, 2¹/₂ divided by 1/3 is equal to 15/2, or 7¹/₂.

The sum of 3 consecutive odd numbers is 51 what is the second number in the sequence
Answer:
The second number in the sequence is 17.
Step-by-step explanation:
Let the three consecutive odd numbers be 2x-1,2x+1 and 2x+3
As per the question, the sum of the 2 odd numbers is 51.
So forming the relevant equation:
(2x-1) + (2x+1) + (2x+3) = 51
=> 6x + 3 = 51
=> 6x = 51-3 = 48
=> x = 48/6 = 8
Calculating the individual numbers:
2x-1 = 2*8 -1 = 16 - 1 = 152x+1 = 2*8+1 = 16 + 1 = 172x+3 = 2*8 +3 = 16 + 3 = 19So the consecutive odd numbers are 15,17,19 and the second number in the sequence is 17.

Two pounds of dried cranberries cost $5.04, 3 pounds of dried cranberries cost $7.56, and 7 pounds of dried cranberries cost $17.64. Write an equation that gives the cost y of x pounds of dried cranberries? Please explain how you got your answer!
The cost equation for dried cranberries is y = 2.52x.
Cost equation:
Using the given data:
2 pounds for $5.04 means each pound costs $5.04/2 = $2.52.
3 pounds for $7.56 means each pound costs $7.56/3 = $2.52.
7 pounds for $17.64 means each pound costs $17.64/7 = $2.52.
Therefore, the cost equation: y = 2.52x where y is the cost and x is the pounds of dried cranberries.

Marvin is trying to finish 1/2 of his test every 2/3 hour. How many hours will it take Marvin to complete his whole test
It will take Marvin 4/3 hours to complete his entire test.
Time taken to complete 1/2 of test = 2/3 hours
The total fraction of the test can be represented as 1
Therefore,
If 1/2 of test = 2/3 hours
1 of test = x
We can solve for x using cross multiplication :
1/2x = 2/3
Multiply both sides by 2 to isolate x
(1/2x × 2) = (2/3 × 2)
x = 4/3 hours
The number of hours it will take to complete the whole test is 4/3 hours
