Given the function below, evaluate h(c) for c = 5
h(c) = 6c² - 76 - 2
Answer:
72
Step-by-step explanation:
Substitute c = 5 into h(c) , that is
h(5) = 6(5)² - 76 - 2 = 6(25) - 78 = 150 - 78 = 72
The nth term of the sequence is n^2 + 20
How many terms in the sequence are less than 50
Answer:
5 terms
Step-by-step explanation:
nth term of the sequence =n^2 + 20
an= n^2 + 20
1st term when n= 1
1^2 + 20= 20
2nd term n= 2
2^2 + 20=24
3rd term when n= 3
3^2 + 20= 29
4th term when n= 4
4^2 + 20= 36
5th term when n= 5
5^2 + 20 =45
6th term when n= 6
6^2 + 20=56
Hence, terms in the sequence are less than 50 are first 5 terms

Write a number with one decimal place, that is bigger than 3 2/3
but smaller than 4
Answer:
Since 15 is greater than 8, the correct expression will be:
15 > 8
Since 4 is less than 134, the correct expression will be:
4 < 134
Since 3 is less than 5, the correct expression will be:
3 < 5
Since 351 is greater than 215, the correct expression will be:
351 > 215
Step-by-step explanation:
The greater a decimal is, the closer it is to one whole. The smaller a decimal is the farther it is from one whole. The first thing you need to look at is the digit number in each decimal. These each have two digits in them, so you can compare them right away

Y/2+1/4=y/6
please help solve for y
Answer:
[tex]y = \frac{-3}{4}[/tex]
Step-by-step explanation:
[tex]\frac{y}{2} + \frac{1}{4} = \frac{y}{6}[/tex]
Lets take all the variable terms in L.H.S & all the constant terms in R.H.S.
(While taking a term from one side to another side , it's sign changes )
⇒ [tex]\frac{y}{2} - \frac{y}{6} = -\frac{1}{4}[/tex]
Now in L.H.S. , lets solve the fractions and reduce its numerator and denominator .
⇒ [tex]\frac{3y - y}{6} = -\frac{1}{4}[/tex]
⇒ [tex]\frac{2y}{6} = -\frac{1}{4}[/tex]
⇒ [tex]\frac{y}{3} = -\frac{1}{4}[/tex]
Lets multiplying 3 on both the sides .
⇒ [tex]\frac{y}{3} \times 3 = -\frac{1}{4} \times 3[/tex]
⇒ [tex]y = \frac{-3}{4}[/tex]

Answer:
Image 1:
1) True (Intersection is (2, 140)
2) False
3) Not sure, but I'm leaning towards F
4) True
Image 2: -4
Step-by-step explanation:
y = 50x + 40
y = 60x + 20
y = 50(6) + 40 = 340
y = 60(6) + 20 = 380
140 = 50x + 40
50x = 100
x = 2
140 = 60x + 20
60x = 120
x = 2
Image 2:
y= mx+b
y = -0.5x - 4
b is the y intercept

Hello there
The coefficient correlation is set on a scale of 1 to -1
1 having the strongest correlation, 5 having an ok correlation and 0 having no correlation
.193 is closest to 0 so the correlation is very weak
Remember if the coefficient correlation is positive the it will have a positive correlation and if its negative then it will have a negative correlation
So we can conclude that the answer is A

Do i need to flip my sign 3x>12
Answer:
divide three from both sides to get x > 4
Answer:
No
Step-by-step explanation:
You only need to flip your sign when dividing by a negative. 3x > 12 = x > 12/3 = x > 4. If the equation were -3x > 12, then it would be x < 4.

) Your father uses text messaging to communicate with his employees. If he sends an average of 19 text messages each day, how many more text messages does he send than you? Write an equation and solve for the unknown value. (2 points)
Answer:
father sends 7 more
Step-by-step explanation:
19-12=7
The equation representing the situation is x = 19 - 12 and the value of x is 7.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given that,
Number of text messages that your father sends a day = 19
Number of text messages that you sends a day = 12
The equation that represents how many more text messages father sends than you is,
x = 19 - 12
where, x represents the number of text messages that your father sends more.
Solving this, we get,
x = 7
Hence father send 7 more messages than you.
