Which of the following equations have no solutions?
Choose all answers that apply:
A
152 - 45 = 750 + 75
B.
15% - 45 = 15x + 75
c
45x – 45 = -15% + 75
D
-450 – 45 = -75x + 75
Answer: B
Step-by-step explanation:
Equation A:
15x - 45 = 75x + 75
=> -120 = 60x
=> x = -2
Equation B:
15x - 45 = 15x + 75
=> 0 = 15
No Solutions
Equation C:
45x - 45 = -15x + 75
=> 60x = 120
=> x = 2
Equation D:
-45x - 45 = -75x + 75
=> 30x = 120
=> x = 4

A container is in the shape of a cuboid the cuboid is 2/3 full of water a cup holds 275 ml of water what is the greatest number of cups
Answer:
12 cups
Step-by-step explanation:
The first step is to calculate the volume of the cubiod
= 36 × 6 × 23
= 4968
= 4968/3 ×2
= 1656×2
= 3312
Therefore the greatest number of cups can be calculated as follows
= 3312/275
= 12
Hence the greatest number of cups is 12 cups
Find the nth term rule for the sequence: 20, 28, 36, 44
Answer:
a(n) = 12 + 8n
a1 = 20
a2 = 28 = 20 + 8
a3 = 36 = 20 + 8.2
a4 = 44 = 20 + 8.3
.......
=> this is a arithmetic with a1 = 20
d = 8
=> an = 20 + 8(n - 1) = 12 + 8n

Answer:
-21
Step-by-step explanation:
put in -3 where x is
-3^2 9
-9-12 = -21
Answer:
-21
Step-by-step explanation:
We know that [tex]f(x)=-x^2-12[/tex] and we also know that [tex]f(x)=f(-3)[/tex]. Therefore, you will have to substitute x with -3.
Calculations:
[tex]f(x)=-x^2-12[/tex]
[tex]f(-3)=-(-3)^2-12[/tex]
[tex]-9-12=-21[/tex]

What is the slope of y = -4?
Answer:
0
Step-by-step explanation:
The line is horizontal.
Explanation:
Think of y = -4 as y = 0x+(-4)
We see that the equation matches the form y = mx+b
m = 0 = slope
b = -4 = y intercept
Side note: this equation graphs out a horizontal line. All horizontal lines have a slope of 0.

Step-by-step explanation:
Tickets for the karaoke talent show sponsored by the Speech Club were priced at $3 for adults and $2 for students. The club treasurer counted 300 tickets sold for a total of $650. Write and solve a system of equations to determine how many adult and student tickets were sold.
Answer:
50 adults and 250 students tickets were sold
Step-by-step explanation:
Given data
Let the number of adults be x and students be y
3x+2y=650------1
x+y= 300---------2
from 2
x= 300-y
put the value of x in 1
3(300-y)+2y= 650
900-3y+2y= 650
900-y= 650
900-650= y
y=250
put the value of y in 2
x+250= 300
x= 300-250
x= 50
Hence 50 adults and 250 students tickets were sold

plz help i will give whoever answers first with the correct answer brainliest
Answer:
Since 1/5 is 0.2
and 1/5 × 9 is 9/5
We can do 0.2 × 9
which you should get 1.8
OR you can do 0.2 + 0.2 + 0.2 +0.2 +0.2 + 0.2 + 0.2 + 0.2 + 0.2 (which is 0.2 added 9 times)
Which also results in 1.8
