Write the equation of the line that passes through the points(-3,6) and (4,1). In point slope form
Answer:
y=10x-14
Step-by-step explanation:
From (4,1) on a graph, you would rise ten and then run to the left 14 times. Remember the rise/run and follow it. What I'm telling is rise you reach (4,6), then count across to (-3,6) to get your answer. You can use demos graphing calculator to help you better or make your own graph.

Please explain/show work. P.s. it won’t let me uncheck a problem, so D isn’t necessarily the answer.
Answer:
D) [tex]\displaystyle\frac{1}{4} x^2[/tex]
Step-by-step explanation:
Hi there!
The correct answer is D.
[tex]\displaystyle\frac{1}{4} x^2[/tex] is the same as [tex]\displaystyle\frac{1}{4}* x^2[/tex], which is the same as [tex]\displaystyle \frac{x^2}{4}[/tex].

Factor the given polynomial completely \. If the polynomial cannot be factored, say that is prime. y^4+10y^3+16y^2
A.y^4+10y^3+16y^2=_____
B. The polynomial is prime
Answer:
y^4+10Y^3+16y^2=0
y^2(y^2+10y^1+16y^0)=0
y^2+10y+16=0
on doing. factors of 10y we get 8y+2y
y^2+8y+2y+16=0
y(y+8)+2(y+8)=0
(y+2)(y+8)=0
1.y+8=0
y=-8
2.y+2=0
y=-2
hence y =(-8,-2)
if F= 1.8C + 32, Solve for C if F = 65
Answer:
1.8333

F = 1.8C +32
C = (F - 32) ÷ 1.8
= (65-32) ÷ 1.8
=1.833
Just throw all the other things to the right, so that only C is on the left

Convert 32 kilometers per hour to miles per day. (3.28 feet 1 meter)
Answer:
477.09 mi/da
Step-by-step explanation:
If student must use conversion given, 3.28ft = 1m, then the following works:
32km/hr = ______mi/da 1 day = 24 hrs, 1m=3.28ft, 1km=1000m,1mi=5280ft
32km/hr x 24hr/day x 1000m/1km x 3.28ft/1m x 1mi/5280ft = 477.09mi/da
If student can use 1km = 0.62mi, some steps can be skipped.

2. Given 90 ml of hydrogen gas collected at 27c,
how milliliters will the hydrogen occupy
ase
MANY
at 42°C ?
Answer:
94.5 ml
Step-by-step explanation:
it's the relation of PV = nRT
as pressure , moles and R are held constant
V1/V2 = T1/T2
where V is volume and T is temperature in "Kelvin"
V2 = V1 * T2 / T1
V2 = 90 * 315 / 300
An unknown polynomial is added to the expression -3x^3+2x-5 and the resulting sum is 4x^3+7x^2-3. what is the unknown polynomial?
Answer:
7x³ + 7x² + 2x - 8
Step-by-step explanation:
Let the unknown polynomial be a
a + -3x³ + 2x - 5 = 4x³ + 7x² - 3
a = 4x³ + 7x² - 3 - (-3x³ + 2x - 5)
a = 4x³ + 7x² - 3 + 3x³ + 2x - 5
a = 7x³ + 7x² + 2x - 8
Unit 1: geometry basics homework 2: segment addition postulate I need the answers for this worksheet please and thank you
The answers to the segment addition problems are :

A segment is simply the shortest distance between two points, For a line segment, it is the line which connects two points.
Given that :
LM = 22 ; MN = 15
The segment LN is defined as :
LN = LM + MN
LN = 22 + 15
LN = 37
2.)
LN = 54
LN = 54 LM = 31
The line segment, LN equals :
LN = LM + MN
54 = 31 + MN
MN = 54 - 31
MN = 23
3.)
DF = 9x - 39
DE = 47
EF = 3x + 10
The line segment, DF equals ;
DF = DE + EF
9x - 39 = 47 + (3x + 10)
9x - 39 = 47 + 3x + 10
9x - 3x = 47 + 10 + 39
6x = 96
x = 96 / 6
x = 16
Hence,
EF = 3x + 10
EF = 3(16) + 10
EF = 48 + 10
EF = 58

Point S is on line segment RT. Given ST = 3x-8, RT = 4x, and RS = 4x-7, determine the numerical length of RT.
Answer:
20.
Step-by-step explanation:
1) according to the condition RT=ST+RS;
2) if RT=4x, ST=3x-8; RS=4x-7, then it is possible to re-write the equation as:
4x=(3x-8)+(4x-7);
3) if to solve this equation, then:
4x=7x-15; ⇔ 3x=15; ⇔ x=5.
4) if x=5, then the length of RT is:
RT=4x=20.
Which of the following is equal to the rational expression when x ≠ -1 or -7?

C. x-1

9514 1404 393
Answer:
C. (x -1)/(x +7)
Step-by-step explanation:
The factor (x +1) in the numerator cancels the same factor in the denominator, leaving the ratio (x -1)/(x +7). This matches choice C.
_____
Additional comment
Even though (x+1)/(x+1) = 1 and can be removed from the expression, the fact that it is undefined at x=-1 means the reduced ratio (x-1)/(x+7) is only a valid representation of the original ratio when x≠-1. The factor (x+1) may be gone, but the domain restriction associated with it remains.

Step-by-step explanation:
you can start with the division -24 ÷ -8 = 3
(-) ÷ (-) = (+)
then multiply 3 × 4 = 12
then divide it by 3
12÷ 3 which equals 12 × (1/3) = 4
Proving functions are inverses of each other: are these inverses of each other band can you explain why or why not.
9514 1404 393
Answer:
a) J(K(x)) = x; K(J(x)) = x; functions are inverses
b) f(g(x)) = 8 -x; g(f(x)) = -x; functions are not inverses
c) f(x) = 4 -x; f^-1(x) = 4 -x. g(x) = x -4; g^-1(x) = x +4
Step-by-step explanation:
a) Substitute for the function argument in the usual way. If the functions are inverses, their composite is the identity function.
J(K(x)) = J(1/3x -2) = 3(1/3x -2) +6 = x -6 +6 = x . . . . functions are inverses
K(J(x)) = K(3x +6) = 1/3(3x +6) -2 = x +2 -2 = x . . . . functions are inverses
__
b) f(g(x)) = f(x -4) = 4 -(x -4) = 4 -x +4 = 8 -x . . . . functions are not inverses
g(f(x)) = g(4 -x) = (4 -x) -4 = -x . . . . functions are not inverses
__
c) To find the inverse function for y = f(x), solve x = f(y).
The inverse of f(x) = 4 -x is ...
x = f(y) = 4 -y
y = 4 -x . . . . . add y-x to both sides
f^-1(x) = 4 -x
and for g(x) = x -4, the inverse is ...
x = g(y) = y -4
x +4 = y
g^-1(x) = x +4
What factors of -27 have the sum of 6
Answer:
9 and -3
Step-by-step explanation:
9 and -3 are both factors of -27 since they can be multiply each other to get -27. Also, they both add up to 6.
The factors of -27 that sum up to 6 are 9 and -3
How to determine the factors of -27 that sum up to 6From the question, we have the following parameters that can be used in our computation:
Factors = -27
Sum = 6
Let the numbers be x and y
So, we have
xy = -27
x + y = 6
Let x be 9 and y be 3
So, we have
9 * -3 = -27
9 - 3 = 6
Hence, the numbers are 9 and -3

f(x) = 2x − 7
f(−3) =
f(3) =
f(−a) =
−f(a) =
f(a + h) =
Answer:
Step-by-step explanation:
f(x) =2x - 7
f( - 3) = 2( - 3) - 7 = - 13
f(3) = 2(3) - 7 = - 1
f(a) = 2a - 7
- f(a) = - (2a - 7) = 7 - 2a
f(a + h) = 2(a + h) - 7 = 2a + 2h - 7
Answer:
f(x) =2x - 7
f( - 3) = 2( - 3) - 7 = - 13
f(3) = 2(3) - 7 = - 1
f(a) = 2a - 7
- f(a) = - (2a - 7) = 7 - 2a
f(a + h) = 2(a + h) - 7 = 2a + 2h - 7
