9(3x - 5) = -9(-5x - 3)
how many solutions do you get when you solve ?
Answer:
one solution
Step-by-step explanation:
Given
9(3x - 5) = - 9(- 5x - 3) ← distribute parenthesis on both sides )
27x - 45 = 45x + 27 ( subtract 45x from both sides )
- 18x - 45 = 27 ( add 45 to both sides )
- 18x = 72 ( divide both sides by - 18 )
x = - 4

Answer: -3/5, 18/32, -10/11, and horizontal.
Step-by-step explanation: Remember the equation for slope? Δy (the change in y), over Δx (the change in x). In other words, rise over run. To solve for Δ, you'd have to subtract the second output (y²) from the first (y¹). There are really no rules as to which has to be minuend and the subtrahend, so I chose to subtract (-1,6) from (4,3) for the first problem.
y¹-y² Δy 3-6 -3
------ or ---- so ------- = ----- The slope is represented by -3/5x
x¹-x² Δx 4-(-1) 5
__________________________________________________________
For the second, substitute the values again (make sure you keep the xs and ys together and in the right order, otherwise your answer will be incorrect). Remember that subtracting a negative number is basically just adding a positive number. That's why the slope is 18/32 and not 4/26.
11-(-7) 18
--------- = -------
29-(-3) 32
___________________________________________________________
For number three, they give you a point, then tell you the y-intercept. With that in mind, also know the second point is (0,17), because the x value at the y-intercept is always 0.
7-17 -10
------ = ------- The slope is -10/11x
11-0 11
___________________________________________________________
4-4 0
------ = --------
6-(-9) 15
Because there is no Δy, but there is Δx, we know that the line for y will be straight and shows no change- it will always be at 4. That said, the line will be horizontal.
I hope this helps. I know this is very confusing at first, but with practice, you'll eventually get the hang of it. I've tried to explain the rules to the best of my ability- let me know if there's anything you don't understand or need more help with.
Sincerely,
Lacia :))
Write 2x+y=17 in slope-intercept form
Answer:
y=-2x+17
Step-by-step explanation:
solve for x 3(-5x+4)+5x-1=-39
Answer:
2
Step-by-step explanation:
x3(−5x+4)+5x−1=−39
−5x4+4x3+5x−1=−39
Step 1: Subtract -39 from both sides.
−5x4+4x3+5x−1−(−39)=−39−(−39)
−5x4+4x3+5x+38=0
Step 2: Factor left side of equation.
(−x+2)(5x3+6x2+12x+19)=0
Step 3: Set factors equal to 0.
−x+2=0 or 5x3+6x2+12x+19=0
x=2 or x=−1.409699
4. determine whether the relation is a function(

Consider the complex number z = 27i. What are the characteristics of the cube roots of z?
Use the drop down menus to complete each sentence.
The cube roots are located on a circle with center at the origin and radius of
.
The cube roots have arguments which differ by
Pi over 3.
Answer:
3 and 2
Step-by-step explanation:
The cube roots are located on a circle with a center at the origin and a radius of 3. The cube roots have arguments that differ by 2 Pi over 3.
What is the complex number?A complex number is one that has both a real and an imaginary component, both of which are preceded by the letter I which stands for the square root of -1.
The given complex number as;
z = 27i
The radius of the cube root is found as;
r=∛x
r=∛27
r=3
The cube roots are located on a circle with a center at the origin and a radius of 3 units.
The argument of a complex number,z=a+ib is;
Θ = tan⁻¹(b/a)
The argument of a complex number z=0+27i
Θ = tan⁻¹(27/0)
Θ = π/2
The cube roots have arguments that differ by 2 Pi over 3.
Hence, the correct answer for the drop-down menu will be 3 and 2.

Solve 56 - 10x>20 + 8x.
O A. x>-2
B. X<-2
C. x >2
D. x<2
Answer:
x<2
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Given
56 - 10x > 20 + 8x ( add 10x to both sides )
56 > 20 + 18x ( subtract 20 from both sides )
36 > 18x ( divide both sides by 18 )
2 > x , thus
x < 2 → D

On a journey of 120 km, a motorist averages
less than 60 km/h. Will the journey take
more or less than 2 hours?
Answer:
More
Step-by-step explanation:
Because the journey is 120km long, and the mortoristgoes less than 60km per hour. So in 2 hours, the motorist will go less than 120 km. So he needs more than 2 hours to go 120 km
a bee flies at 12 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 14 minutes, and then flies directly back to the hive at 8 feet per second. It is away frim the hive for a total of 16 minutes. what equation can can you use to find the distance of the flowerbed from the hive? How far is the flowerbed from the hive?
Answer:
(x/12 + 840 + x/8) = 960
576 feets
Step-by-step explanation:
Given that :
Speed to flower bed = 12 ft/s
Speed back to hive = 8 ft/s
Time spent at flower bed = 14 minutes = 14*60.= 840
Total time = 16 mins = (16 * 60) = 960
Let distance between bee hive and flower bed = x
Time taken to flower bed = x / 12
Time taken back to hive = x /8
(x/12 + 840 + x/8) = 960 - - equation
L.C.M of 12 and 8 = 24
(2x + 20160 + 3x)/ 24 = 960
(2x + 20160 + 3x) = 23040
5x = 23040 - 20160
5x = 2880
x = 2880 / 5
x = 576
Distance between flowerbed and hive = 576 feets

A survey asked students whether they would like a drama club, a step team, both clubs, or neither club. The results are below:
1. 34 students like a drama club
2. 27 students like step team
3. 14 students like both
4. 13 students like neither
Hi, you've asked an incomplete question. Here are the remaining questions:
a) Describe what each region in the Venn diagram represents.
Region I: In drama club, not in step team.
Region II: In both clubs.
Region III: In step team not in drama.
Region IV: Not in either club.
b) How many students were in only one of the two clubs?
c) How many students were in the drama club or in the step team?
d) How many students were surveyed?
Attached is the Venn diagram depicting the regions.
Explanation:
b) By adding the number of students that like drama club and those that like step club we can derive the answer: 34 + 27 = 61.
c) By adding 34 + 27 + those that like both (14) = 75.
d) The total number of students surveyed is gotten by summing any number in attached the diagram: 34 + 27 + 14 + 13 = 88.
