Answer:
below
Step-by-step explanation:
make the ordered pairsso if x=1 then y is... it's -2so if x=2 then y is... it's -4so if x=3 then y is... it's -6so now you have the ordered pairs (1,-2) and (2,-4) and (3,-6)Now plot themFactor f(x) = 4x2 + 11x? - 104x + 105 into linear factors given that – 7 is a zero of f(x).
f(x) = 4x + 11x2 - 104x + 105 = |
(Factor completely.)
Answer:
f(x) = 4x + 11x2 - 104x + 105 = (x - 3)(x + 7)(4x - 5)
Step-by-step explanation:
f(x) = 4x^3 + 11x2 - 104x + 105
has the coefficients {4, 11 -104, 105}. We perform synthetic division using the given -7 as divisor:
-7 / 4 11 -104 105
-28 119 -105
-----------------------------------
4 -17 15 0
Since the remainder is zero (0), we have shown that -7 is a zero of f(x). The coefficients of the quotient (above) are {4, -17, 15}. Let's try factoring the corresponding polynomial again using synthetic division. Start out by using 5 as divisor and determining whether or not the remaindeer is zero:
5 / 4 -17 15
20 15
-------------------------
4 3 30 No, the remainder is 30 and so 5 is not a
root of this quadratic. Try the divisor 3 instead:
3 / 4 -17 15
12 -15
---------------------------
4 -5 0 Yes, the remainder is 0 and so 3 is a root.
Thus, the given f(x) = 4x + 11x2 - 104x + 105 factors as follows:
f(x) = 4x + 11x2 - 104x + 105 = (x - 3)(x + 7)(4x - 5). Notice that the coefficients of the last factor come from those we found above when using 3 as a divisor in synthetic division.

Examine the following table.
Does this table represent a probability distribution?
Explain your answer.
a. Yes, because the sum of the probabilites is less than one.
b. Yes, because the sum of the probabilities is more than one.
C. No, because the sum of the probabilities is more than one.
d. No, because the sum of the probabilities is less than one.
Answer:
the answer is c
Step-by-step explanation:
edge 2020
The correct option is (C). No, because the sum of the probabilities is more than one.
What is probability distributionIn mathematics, a probability distribution is a function that expresses the likelihood of many possible values for a variable. Graphs and probability tables are common ways of displaying probability distributions.
In the given table, the probabilities are,
P(x) = 0.2, 0.3, 0.4, 0.1 and 0.05.
The sum of the probabilities = 0.2 + 0.3 + 0.4 + 0.1 + 0.05
= 1.05
Since, the sum of the probabilities is more than one, therefore, the table does not represent the probability distribution.

height of these 5 boys?
What are the operation to solve the problem?
pls answer
Wll not just this question, but whenever you need to find average, you have to:
Wait, for example let's take ur question:
1st step we will add up all the values aka heights:
5.4+6.12+7.02+4.9+6.25=29.69
And then how many values did you take???
Its, 5 values
1st value= 5.4
2nd value=6.12
aaand so on....
However, then we will have to divide the sum by no.of values
29.69÷5=5.938

School A has graduated 1,700 students and graduates
50 students every year. School B has graduated 600
students, but graduates 150 every year. How many years (Y)
will it be before School B has as many graduates as School A?
Answer:
the answer is 11 years
Step-by-step explanation:
if school A is graduated 50/years,
the graduated in 11 years is 550
added of graduated 1,700 in 550 is 2,250
if school B is graduated 150/years,
the graduated in 11 years is 1650
added of graduated 600 in 1650 is 2,250
so School A and B is to be equal in 11 years

Solve the following equation
Answer:
0
Step-by-step explanation:
write an equation for a line perpendicular to y=-2x+1 and passing through the point (-4,3)
Answer:
Step-by-step explanation:
The reference line has a slope of -2. A perpendicular line will have a slope, m, that satisfies
-2m=-1, so it will have a slope of 1/2 then our line y=mx+b becomes
y=x/2+b, using point (-4,3) we have
3=-4/2+b
3=-2+b
b=5 so our line is
y=x/2+5 or more neatly
y=(x+10)/2
What is is this graph representing??
A. Linear
B. Exponential
C. Neither

An orchand has 8 times more apple trees than pear trees. There are 981 trees in all. How many more apple trees are there
Answer:
763
Step-by-step explanation:
there are 763 more apple trees than pear trees
Step-by-step explanation:
so, first we write the words into equations.
8P = A because there are 8x apples per x pear, so to make it equal we must multiply pears by 8. P+A = 981. replacing "A" in the second equation with "8P" to get P+8P=981=9P divide both sides by 9 to get 109 pear trees. knowing this we can get 981-109=A=872 apple trees. the problem asks for A-P which we can replace the numbers to get (872)-(109)=763 more trees
Answer:122.625
Step-by-step explanation:981 divided by 8 equals 122.625

Jimarcus plans to build a free fence 5 1/3 yards long at the back of his garden. How many 2/3- yard sections of fence will he need
Answer:
8
Step-by-step explanation:
Jimarcus plans to build a fence of 5 1/3 yards longs
He want to divide it into 2/3 yard sections
Therefore the number that will be produced can be calculated as follows
= 5 1/3 ÷ 2/3
= 16/3 ÷ 2/3
= 16/3 × 3/2
= 16/2
= 8

Is 14,48,50 a Pythagorean triplet
Step by step explanation please
Answer:
yes
Step-by-step explanation:
If the values are a Pythagorean triplet then the square of the largest value should equal the sum of the squares of the other 2
largest value = 50 ⇒ 50² = 2500
14² + 48² = 196 + 2304 = 2500
Since 50² = 14² + 48² then 14, 48, 50 are a Pythagorean triplet

[tex]ax+by=c[/tex]
[tex]bx+ay=c[/tex]
Answer:
The answer is below
Step-by-step explanation:
Firstly, let us find the value of x. Multiply the first equation by a and the second equation by b to get:
a²x + aby = ca (3)
b²x + aby = cb (4)
Subtract equation 4 from equation 3 to get:
x(a² - b²) = c(a - b)
but a² - b² = (a + b)(a - b)
x(a + b)(a - b) = c(a - b)
x(a + b) = c
[tex]x=\frac{c}{a+b}[/tex]
Secondly, let us find the value of y. Multiply the first equation by b and the second equation by a to get:
abx + b²y = cb (5)
abx + a²y = ca (6)
Subtract equation 5 from equation 6 to get:
y(a² - b²) = c(a - b)
but a² - b² = (a + b)(a - b)
y(a + b)(a - b) = c(a - b)
y(a + b) = c
[tex]y=\frac{c}{a+b}[/tex]
