Answer:
x = b - y
Step-by-step explanation:
To get x by itself, subtract y from both sides.
y + x = b . . . . . . . . . given
y - y + x = b - y . . . . subtract y
x = b - y . . . . . . . . . simplify

Answer:
[tex]\frac{1}{64}[/tex]
Step-by-step explanation:
(1/8)^2 is actually just (1/8)*(1/8)
We multiple the numerators, 1*1, to get 1,
And the denominators, 8*8, to get 64
So the anwser is (1/64)

Find f(2) if f(x) = (x + 1)2.
a 9
b 6
c 5
Answer:
b
Step-by-step explanation:
x = 2 in this situation, so plug in 2 for x.
f(2) = (x + 1)2
f(2) = (2 + 1)2
f(2) = (3)2
f(2) = 6
f(2) = 6. That means b is the answer.

To find the quo 2/5 divided 1/4.
Answer:
A. Multiply 2/5 by 4
Step-by-step explanation:
Because when you dividend fraction
1,write the reciprocal of the second fraction number and multiply with the first fraction number
2,multiply the numerators and denominators of both fraction..
the reciprocal of 1/4 is 4/1 =4so the answer is 2/4 by4

solve for x using the correct order operations
12- (3 times 2)^2 + 4 times 3 = x
A x = -60
B x = -12
C x= 48
D x = 12
please help i will give brainliest :))
Answer:
B: x = -12
Step-by-step explanation:
12 - (3 × 2)^2 + 4 × 3
Use PEMDAS, meaning solve what's in the parentheses first (P stands for parentheses)
12 - (6)^2 + 4 × 3
We get 6 because 3 × 2 = 6
Next step is solve any exponents (E for exponents)
12 - 36 + 4 × 3
We get 36 because 6 × 6 = 36 (the exponent was 2 meaning multiply the same number, 6, twice: 6 × 6)
Now we move on to multiplication and division (M for multiplication and D for division)
These are interchangable in that either can go first depending on its location in the equation
However, since there is no division in this problem we automatically skip to multiplication
12 - 36 + 12
We answered 12 because 4 × 3 = 12
Our last steps in PEMDAS are addition and subtraction (A for addition and S for subtraction)
These are also interchangable, but both are apparent in this problem
Now it depends on location
Whichever sign (addition or subtraction) is first in accordance from left to right is where we start first)
Subtraction is first
-24 + 12
Now we add -24 + 12
-12
Which exponential function is represented by the values in the table?
Answer:
[tex]\displaystyle f(x)=4\cdot\left(\frac{1}{2}\right)^x[/tex]
Step-by-step explanation:
Exponential Function
The exponential function can be written with the general equation:
[tex]f(x)=A\cdot r^x[/tex]
Where A is the value when x=0 and r>0 is the ratio. If r is greater than 1, the function is increasing, if r is less than 1, the function is decreasing.
The table shows the relation between values of x and values of the function y. Note that as x increases (one by one), y decreases with a ratio of 1/2. Only the last two choices have ratios of r=1/2. We only have to test which one of them has the correct value of y=4 when x=0.
Substituting in the third function:
[tex]\displaystyle f(x)=4\cdot\left(\frac{1}{2}\right)^x[/tex]
[tex]\displaystyle f(0)=4\cdot\left(\frac{1}{2}\right)^0[/tex]
[tex]f(0) = 4[/tex]
This gives the correct value of f(0)=4.
Substituting in the fourth function:
[tex]\displaystyle f(x)=\frac{1}{2}\cdot\left(\frac{1}{2}\right)^x[/tex]
[tex]\displaystyle f(0)=\frac{1}{2}\cdot\left(\frac{1}{2}\right)^0[/tex]
[tex]f(0) = \frac{1}{2}[/tex]
This choice is wrong
Correct choice:
[tex]\boxed{\displaystyle f(x)=4\cdot\left(\frac{1}{2}\right)^x}[/tex]

Step-by-step explanation:
Have to find x,y and z
Answer:
x=2, y=5
Step-by-step explanation:
the triangle that x is in is a right triangle (don't remember the theorem sorry)
use pythagorean theorem (a^2 + b^2 = c^2)
x is the hypotenuse(c)
1 squared plus /3 squared =c squared
1+3= c squared
4= c squared
c=2
x=2
find y using pythagorean theorem as well
/12 squared plus 2 squared = y squared
y is the hypotenuse
12+4=y squared
16= y squared
4=y
add one to account for that extra little piece
y=5
... I don't see z
Answer:
y= if it is the hypoteneuse for the whole triangle it √16 or 4, if it is the side of the smaller triangle it is 3
x=√4 which is 2
z= I don't think ther's a z

What is a inelastic collision
IF YOU WANT BRAINLIEST DESCRIBE IT IN YOUR OWN WORD PLS
Answer:
Kindly check explanation
Step-by-step explanation:
Think of inelastic Collison as a phenomenon whereby the colluding bodies do not rebound. That is the direction of motion of the two bodies after collision is in a single direction, moving with a single final velocity as opposed to bodies moving in different directions with differing final velocities after collision during an elastic collision. Therefore, the final kinetic energy during an inelastic Collison isn't conserved.
Mathematically,
Inelastic Collison can be written has :
m1u1 + m2u2 = v(m1 + m2)
Whereby ;
m1, m2 are masses of the first and second colliding objects
u1 and u2 are their initial velocities
Note that, we only have a single final velocity, v, which shows that the colliding objects move in the same direction after collision.
8. 6r + 5 = 4 6 - 7y -20
Answer: r=-7/6y+7/2
Step-by-step explanation:
Step 1: Add -5 to both sides.
6r+5+−5=−7y+26+−5
6r=−7y+21
Step 2: Divide both sides by 6.
6r/6=-7y+21/6
Lupita bought 7 pounds of pretzels at a local wholesaler for $16.80. Her friend Charles bought 5 pounds of pretzels at the supermarket for $12.75. Charles thinks he got the better deal because $12.75 is less than $16.80. Is Charles’s reasoning correct? Explain why or why not.
Answer:
Charles's reasoning is wrong.
Step-by-step explanation:
Lupita has 7 pounds for 16.8 and Charles has 5 pounds for 16.8.
Let's set up ratios.
So Lupita got the best deal, not Charles. Poor him.
7x + 2y = 12
-3x -2y = 4
Answer:
(4, -8) or x=4 y=-8
Step-by-step explanation:
Answer: x=4 and y=−8
Step-by-step explanation: 7x+2y=12, −3x−2y=4
7x+2y+−2y=12+−2y
7x /7 = −2y+12 /7
x= −2 /7 y+ 12 /7
−3( −2 /7 y+ 12 /7 )−2y=4
−8 /7 y+ −36 /7 + 36 /7 =4+ 36 /7
−8 /7 y / /−8/7 = 64 /7 /−8 /7
y=−8
x= −2 /7 y+ 12 /7
x= −2 /7 (−8)+ 12 /7
x=4
x=4 and y=−8
