What will be the first step in answering this equation 9z+3=3z+15 ?
Answer:
Subtract 3z from each side
Step-by-step explanation:
9z+3=3z+15
Subtract 3z from each side
9z-3z+3=3z-3z+15
6z +3 = 15
Subtract 3 from each side
6z+3-3 = 15-3
6z = 12
Divide by 6
6z/6 = 12/6
z=2
Answer:
9z-3z+3=15

Answer:
D. The parabola is translated down 2 units.
Step-by-step explanation:
Comparing the two functions f(x), we see that the second one has a constant of 1 where the first one has a constant of 3. That means every value produced by the second function will be 2 units less than the value produced by the first function.
D. The parabola is translated down 2 units.

The correct answer is,
Sqrt(2) + 3 > sqrt(7) - 3
Which statement is true about this equation? -(2x + 4) + x = 3x − 4x − 4 The equation has no solution. The equation has infinitely many solutions. The equation has one solution, x = 4. The equation has one solution, x = 0.
Since there is a variable, there are infinitely many solutions.
Answer:
there are infinitely many solutions.
4x+57=−133 what is x
4x + 57 = -133
Subtract 57 from both sides.
4x = -190
Divide each side by 4
x = -47.5
answer
-47.5
steps
-133 - 57 = -190
-190 divided by 4 = -47.5
f(x)=2x -7, What is x when f(x)=-15?
Answer:
x = -4
Step-by-step explanation:
Plug in -15 into the equation:
f(x) = 2x - 7
-15 = 2x - 7
Solve for x:
-15 = 2x - 7
-8 = 2x
-4 = x

Solve for Y: when X = 6 y= 2x +1
Answer:
y=13
Step-by-step explanation:
2(6)+1
=12+1
=13
Answer:
y=13
Step-by-step explanation:
by replacing x in the equation with 6 the equation becomes y=2(6)+1 this is just a simple equation that you use to get the answer. 2×6 is 12 and 12+1=13 so y=13.
A plumber has 8 9/10 feet of rubber tubing to make 2 rubber pipes. He will use3 1/12 feet of tubing to make each pipe. The plumber says he will have about 3 feet of rubber tubing after he makes the pipes. Is his statement reasonable?
Answer:the answer is D
Step-by-step explanation:
This is reasonable because feet can be rounded to 9 feet and feet can be rounded to 3 feet. Since 9 - 2(3) = 3, the plumber will have about 3 feet of rubber tubing left. its true make sure you read the answer to make sure bc they can mix them up LOL
Write 0.39 as a fraction in simplest form.
To write the repeating decimal as a fraction, first let n=0.39. Then
find 100n.
n = 0.39
100n = 39.39
Subtract to eliminate the repeating part.
100n = 39.39
n = 0.39
99n =

The slope of the line will be equal to 1.
What is a slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.
The slope of the line will be calculated by using the formula below:-
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
The given points are:-
Choose (x1, y1)
X₁= 2 y₁= -5
Identify (x2, y2)
X₂= 7 y₂= 1
Apply the slope formula:-
m= ( y₂ - y₁ ) / ( x₂ - x₁ )
m= 1-(-5)/7-2.
m= ( 5 / 5 )
m = 1
Therefore, the slope of the line will be equal to 1.

How do you write 27 in standard form?
Please can you give more different examples and explanation detail so I will understand.Please guys help...
Answer:
Cardinal: twenty seven
Ordinal: twenty seventh
Step-by-step explanation:
hope this helps!!!!!!
Answer:
2.7×10
Step-by-step explanation:
Basically the number 27 has to be in between the numbers 0 and 10.
So to do that you have to divide 27 by 10 until it is between 0 and 10 which is then 2. 7,
And to get the 10 you have to count how many times you had to divide 27 by 10 to get which is 1 so you leave it as ten so the answer you get is
2.7 x 10

Investigate the range of each parent function below over the interval o
ranges from least to greatest.
Identity function, reciprocal function, quadratic function, cubic function, square root function
Answer:
Here we have the domain:
D = 0 < x < 1
And we want to find the range in that domain for:
1) y = f(x) = x
First, if the function is only increasing in the domain (like in this case) the minimum value in the range will match with the minimum in the domain (and the same for the maximums)
f(0) = 0 is the minimum in the range.
f(1) = 1 is the maximum in the range.
The range is:
0 < y < 1.
2) y = f(x) = 1/x.
In this case the function is strictly decreasing in the domain, then the minimum in the domain coincides with the maximum in the range, and the maximum in the domain coincides with the minimum in the range.
f(0) = 1/0 ---> ∞
f(1) = 1/1
Then the range is:
1 < x.
Notice that we do not have an upper bound.
3) y = f(x) = x^2
This function is strictly increasing, then:
f(0) = 0^2 = 0
f(1) = 1^2 = 1
the range is:
0 < y < 1
4) y = f(x) = x^3
This function is strictly increasing in the interval, then:
f(0) = 0^3 = 0
f(1) = 1^3 = 1
the range is:
0 < y < 1.
5) y = f(x) = √x
This function is well defined in the positive reals, and is strictly increasing in our domain, then:
f(0) = √0 = 0
f(1) = √1 =1
The range is:
0 < y < 1
What is the value of x in the equation: 3 (4x - 1) - 3x = - (x + 2)?
Give your final answer in Decimal form.
Solution:
[tex]-0.5[/tex]
Steps:
[tex](4x - 1) - 3x = - (x + 2)[/tex]
Start with the left side and combine like terms
[tex]4x-1-3x=-(x+2)\\[/tex]
Combine [tex]4x[/tex] and [tex]-3x[/tex]. After doing this, you would have [tex]x[/tex] because 4-3 = 1
[tex]x-1 =-(x+2)[/tex]
Then, you can distribute the negative on the right side
[tex]-(x+2) = -(x)+-(2) = -x-2[/tex]
You would end up with
[tex]x-1=-x-2[/tex]
Add x to each side.
[tex]2x-1=-2[/tex]
Add 1 to each side
[tex]2x=-1[/tex]
Divide each side by 2 to simplify.
[tex]x=-1/2\\x = -0.5[/tex]
4(5n -7) =10+2 i need step by step explanation i dont get it
Answer:
n=2
Step-by-step explanation:
4(5n-7)=10+2
1) First, distribute (multiply out 4)
20n-28=10+2
2) Combine like terms (add 10 and 2)
20n-28=12
3) Isolate the variable (Add 28 to 12)
20n=40
4) Isolate the variable (Divide by 20)

What is the measure of the smallest angle in the right triangle below?
(2x)
(x + 6)°
28°
56°
34°
12°
Answer:
34°
Step-by-step explanation:
If we assume that the acute angles in the triangle are 2x and (x+6), then we have ...
2x +(x +6) = 90
3x +6 = 90 . . . . . . simplify
x + 2 = 30 . . . . . . . divide by 3
x = 28 . . . . . . . . . . subtract 2
Then the angles are ...
2x = 2(28) = 56
x+6 = 28+6 = 34
The smallest angle is 34°.
