Answer:
(x + 5) is not a factor of, [tex] f(x) = x^ 3 − 4x^2 + 3x + 7 [/tex]
Step-by-step explanation:
[tex] f(x) = x^ 3 − 4x^2 + 3x + 7 \\ \\ let \: x + 5 = 0 \\ \implies \: x = - 5 \\ \\ plug \: x = - 5 \: in \: f(x) \\ \\ f( - 5) = ( - 5)^ 3 − 4( - 5)^2 + 3( - 5) + 7 \\ \\ f( - 5) = - 125 − 4(25) - 3( 5) + 7 \\ \\ f( - 5) = - 125 − 100 - 15 + 7 \\ \\ f( - 5) =7 - 240 \\ \\ f( - 5) = - 233 \\ \\ \because \: f( - 5) \neq 0 \\ \implies \: remainder\: is\: not\: zero\\ \therefore \: (x + 5) \: is \: not \: a \: factor \: of \: \\ f(x) = x^ 3 − 4x^2 + 3x + 7 \\ [/tex]
Given side lengths 4 units, 8 units, and x units, determine the range in which x must lie in order for a triangle to exist.
A)
X > 12
B)
0
C)-4
D)
4
Answer:
A is the correct answer
Step-by-step explanation:
Mathematically if we have lengths a, b and c
For a triangle to occur, let us say that the third side is c
then a + b must be greater than or equal to c
Hence c must be equal to (4 + 8) or greater than (4 + 8)
With the options given , A is the correct answer

Sarah said that 26÷8 is the same as/equal to 14÷4 and the answers are "3r2". What did Sarah do wrong? 5th grade math help fir my daughter. I think Sarah meant: 26÷8 is the same as or equal to 13÷4 instead of 14÷4 which is what she did wrong?
Answer:
Yes
Step-by-step explanation:
Yes, that is exactly what Sarah did wrong. Apparently, she tried to divide both the numerator and denominator in this problem by 2 (half) but divided the numerator incorrectly. 26 divided by 2 would equal 13 but Sarah mistakenly calculated it as 14 which would give her a totally different value when divided by the new denominator. If were to have divided correctly it would give her [tex]\frac{13}{4}[/tex] which is the same as [tex]\frac{26}{8}[/tex]

B is between A and C. If AB = 2x + 1, BC = x, and AC = 22. Find AB.
Answer:
15
Step-by-step explanation:
AB + BC = AC
2x + 1 + x = 22
3x + 1 = 22
3x = 22 -1
3x = 21
x = 21/3
x = 7
AB = 2*7 +1
= 14 + 1
= 15

From the image attached, we have the following recorded temperature for 4 days in January.
Monday: -5° F
Tuesday: -1° F
Wednesday: 3° F
Thursday: 5° F
Option A is correct because the temperature on Monday and Tuesday is negative and thus below zero.
Option B is not correct because the temperature on Monday and Thursday are not the same since they are -5° F and 5° F respectively
Option C is not correct because the temperature on all days was not above zero since on Monday and Tuesday had negative temperatures
Option D is not correct because the lowest temperature below zero is on Monday and not Thursday
Option E is not correct because the temperature on Wednesday and Thursday are positive and not below zero.
Option F is correct because Monday had a temperature of -5° F which is the lowest gotten below zero
The temperature on Monday and Tuesday is negative and thus below zero.
The temperature on Monday had a temperature -5F which is the lowest value below zero.

Car A is traveling east at a steady speed of 45 miles per hour. After 2 hours, it is 100 miles east of Johnstown
Car B is traveling east on the same road. it’s distance east of Johnstown is represented by the graph.
Where were the two cars in relation to each other when they began traveling?
A. Car B was 10 miles east of car A
B. Car A was 45 miles east of car B
C. Car A was 10 miles east of car B
D. Car B was 40 miles east of car A
Answer:
The correct option is;
A. Car B was 10 miles east of car A
Step-by-step explanation:
The given parameters are;
The speed of car A = 45 miles per hour
The direction of car A = East
The distance of car B from Johnstown after 2 hours = 100 miles east
The direction of Car B = East
The distance of car B from Johnstown is given on the graph
Therefore, the initial distance of car A from Johnstown when car A began driving is given as follows;
The initial distance, east, of car A from Johnstown = 100 - 2 × 45 = 10
∴ The initial distance, east, of car A from Johnstown = 10 miles
From the graph, the initial distance, east, of car B from Johnstown = 20 miles
Therefore, car B was 10 miles east of car A
Answer:
Car B was 10 miles east of car A
