Answer:
The leading coefficient of the polynomial is 5 .
Step-by-step explanation:
f(x) = 6x^5 + 9x^4 + 2x^3 + 3x^2 - 4x -6
In this polynomial , the highest exponential is the leading coefficient .
So there are 5 coefficients ,
5 , 4 , 3 , 2 , and x
so above , the highest one is 5 .
b) The number when 75% of the number is 12
Answer:
16
Step-by-step explanation:
(75/100)*x=12
75x=12*100
75x=1200
x=1200/75
x=16
Answer:
16
Step-by-step explanation:
divide 75 by 100
multiply 12 by 100
which is 1200
divide 1200 by 75
and your answer is 16

9. Krista and Emily wrote an equation of a line that is parallel to the line y = 3x - 1 and passing
through the point (5,9). Is either of them correct? Explain your reasoning?
Krista:
9 = 3(5) + b
9 = 15 + b
-6 = b
y = 3x - 6
Emily:
y- 9 = 3(x - 5)
y- 9 = 3x - 15
y = 3x - 24
Answer:
Explanation:
Step-by-step explanation:
Hey there!
The equation, of a st. line that passes through point (5,9) is,
[tex](y - y1) = m1(y - y1)[/tex]
Put the values,
[tex](y - 9) = m1(x - 5)[/tex]
It is 1st equation.
Now, another equation is,
y = 3x-1.........(ii)
Comparing the equation with y = mx+c.
Slope (m2)= 3
As per the parallel lines,
m1=m2=3
Putting,
the value of m1 in equation(i)
(y-9)= 3(x-5)
y-9= 3x - 15
y = 3x - 6.
So, Krista equation is correct.

what is the answer to g+3=17
Answer:
g=14
Step-by-step explanation:
do 17-3, the answer is 14, meaning 14=g
Answer:
g = 14
Step-by-step explanation:
g+3 = 17
Subtract 3 from each side
g+3-3 = 17-3
g = 14

Hugh bought some magizines that cost 3.95 each and some books that cost 8.95 each. He spent a total of 47.65.If Hugh bought 3 magazines,how many books did he buy
Answer:
4 books
Step-by-step explanation:
We are told that: Hugh bought some magazines that cost 3.95 each
Hugh bought 3 magazines.
Hence, total cost of magazines = 3 magazines × 3.95
= 11.85.
Total cost of magazines = 11.85
From the question, we know that, the total amount Hugh spent = 47.65
Hence, The total cost for books =
Total amount spent - Total cost of magazines
= 47.65 - 11.85
= 35.80
Therefore, the total cost of books = 35.80
We are told in the question that the cost of books is 8.95 each or 8.95 per book.
Hence, the number of books that Hugh bought is calculated as :
35.80/8.95
= 4 books
Therefore, Hugh bought 4 books
-1/2m=-9 what does m=

Step 2: Multiply both sides by -2
m = 18
There are 7 more sweaters than shirts in the drawer. There are 15 sweaters and shirts in the drawer in all. How many shirts are there in the drawer? Let S represent the number of shirts. Which equation represents the situation
Answer:
7 + 2s = 15
4 shirts
Step-by-step explanation:
Let's say w denotes sweaters and s denotes shirts.
Since there are 7 more sweaters than shirts:
w = 7 + s
There are a total of 15 sweaters and shirts in all, so:
w + s = 15
Substitute 7 + s in for w in the second equation:
w + s = 15
7 + s + s = 15
7 + 2s = 15
Solving for s:
7 + 2s = 15
2s = 15 - 7 = 8
s = 8/2 = 4 shirts
Thus, the equation is 7 + 2s = 15, and there are 4 shirts.

HELP !!! Evaluate f(-2) for the function f(x) = 3x2 + 2x - 5
Answer:
3
Step-by-step explanation:
So we have the function:
[tex]f(x)=3x^2+2x-5[/tex]
To evaluate the value of f(-2), substitute -2 for x. Thus:
[tex]f(-2)=3(-2)^2+2(-2)-5[/tex]
Square first:
[tex]f(-2)=3(4)+2(-2)-5[/tex]
Multiply:
[tex]f(-2)=12-4-5[/tex]
Now, subtract:
[tex]f(-2)=8-5=3[/tex]
So:
[tex]f(-2)=3[/tex]
And we're done!
What is
the circumference of a circle with radius 3.5cm. Take [Pi=22/7]
Answer:
22cm
Step-by-step explanation:
Circumference of a circle = 2πr
π = 22/7
r = 3.5
Circumference of a circle = 2 × (22/7) × 3.5
Circumference of a circle = 22cm.

The length of an alligator in a zoo is 14 5/6 feet.The everglades national parks list the longest alligator ever reocord in florida at 17 5/12 feet. Which is the differnce in their lenghth
Answer:
The difference in the lengths of the two alligators = 3
Step-by-step explanation:
First, let us make the lengths improper fractions, then we will find the difference from there.
Alligator 1:
Length = [tex]14\frac{5}{12} = \frac{173}{12}[/tex]
To convert to improper fraction, multiply the denominator by the whole number, and then add the denominator [(12 × 14) + 5]
Alligator 2:
Length = [tex]17\frac{5}{12} = \frac{209}{12}[/tex]
Now Let us find the difference between the lengths:
[tex]\frac{209}{12} - \frac{173}{12} = \frac{36}{12} =3[/tex]
Therefore the difference in the lengths of the two alligators = 3
The circumference of a quarter is approximately 7.54 mm. What is its diameter to the nearest tenth of a millimeter? (π = 3.14)
Answer:
2.40mmStep-by-step explanation:
In this problem. we are required to solve for the diameter of a circle.
Given data
circumference of circle c= 7.54mm
we know that the expression for the circumference is given as
c= 2πr
We can substitute our given data to solve for r
7.54= 2*3.142*r
7.54=6.284*r
divide both sides by 6.284 we have
r= 7.54/6.284
r= 1.199
diameter = 2*r
diameter= 1.199*2
diameter= 2.399
to the nearest tenth
diameter= 2.40mm
