Algebra 1. 5(x + 6) – 2x = 3(x + 10)
Answer:
your answer is 3x+30=3x+30 so they are the same
Step-by-step explanation:
LOOK AT THE IMAGE ABOVE to solve the problems. Please only answer if you KNOW.
Show full steps please.
It’s due today!
Answer:
The lines are parallel
Step-by-step explanation:
The slopes are the same
The equations are both written in slope intercept form
y = mx+b where m is the slope and b is the y intercept
-3/5 is the slope in both equations
When the slopes are the same the equations are parallel
They have different y intercepts, so they are different lines ( if they have the same y intercept and same slope, they would be the same line)
From definition ,find derivatives of [tex]a^{x}[/tex]
Answer:
Step-by-step explanation:
d /d x [ a ^x ]
= d/ d x [ e ^ln ( a ) x ]
= e ^ln ( a ) x ⋅ d /d x [ ln ( a ) x ]
= e ^ln ( a ) x ⋅ ln ( a ) ⋅ d /d x [ x]
= e ^ln (a ) x ln ( a ) ⋅ 1
= ln ( a ) e ^ln ( a ) x

Solve for x in the following equation:
kx = m + nx
Answer:
x=[tex]\frac{m}{k-n}[/tex]
Step-by-step explanation:
First you subtract nx from both side getting kx-nx=m.
Then you factor out x getting x(k-n)=m
and now you divide both sides from (k-n) and you will get the answer.

What is the greatest common factor of 24 and 6?
Answer:
6
Step-by-step explanation:
The factors of 6 are: 1, 2, 3, 6
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
Then the greatest common factor is 6.
Answer:
6
Step-by-step explanation:
A factor is a number that can be multiplied by another to get the given product. 6 is the largest number that is a factor of both 24 and 6.
6*4=24 and 1*6=6.

1/3(3−z)
Answer:
1/3(3 - z) = 1 - 1/3zStep-by-step explanation:
Given expression1/3(3 - z)To findComplete the equation to have infinitely many solutionsSolutionAn equation has infinitely many solutions if the variable cancels and constants are same on left and right sides of the equation
Let the right side be an expression m, then
1/3(3 - z) = m1/3*3 - 1/3z = m1 - 1/3z = mSo we need same expression on the right side, the equation is:
1/3(3 - z) = 1 - 1/3z·A nutritionist recommends that an adult male consume 55 grams of per day. It is acceptable for the fat intake to differ from this amount by at most 25 grams. Write and solve an absolute-value inequality to find the range of fat intake that is acceptable. Graph the solutions.

8. 2|x - 7| =-4
What is the solution to this absolute value equation
The answer is there is no solution.
Answer:
No solutions
Step-by-step explanation:
2 | x - 7 | = -4 We need to isolate the absolute value, so in order to do that we need to divide 2 from both sides of the equation.
| x - 7 | = -2
Absolute values can not be equal to a negative number.
Therefore, your answer is no solutions.

Suppose that 19 inches of wire costs 76 cents. At the same rate, how many inches of wire can be bought for 48 cents?
Answer: 12 inches
Step-by-step explanation:
Because 19 inches costs 76 cents. If you divide 19/19 you get 1 inch. Also divide 76/19 and you get 4 cents. Now it’s asking how many inches could be bought for 48 cents. So 48/4 equals to 12 and that’s your answer. You see 19x4=76. And 12x4= 48. I hope that helped you.
Write a system of equations that represents the given equation then find the two numbers
The sum or two numbers is 68. The difference is 12
Answer:
40 and 28
Step-by-step explanation:
We have two unknown numbers, so let's call them x and y for now.
We know the sum of the two numbers is 68, and the difference is 12, so let's substitute those two numbers for x and y:
x+y=68
and
x-y=12
Because both of these systems are true, we can take both these equations and combine them, by adding each side of one equation with the corresponding side of the other.
So we have:
(x+y)+(x-y)=(68)+(12)
2x=80
x=40
Now we know one of the numbers, x, is equal to 40, so now we can plug that number back into one of the two original equations, x+y=68 or x-y=12. I'll choose x-y=12.
After plugging in x, we get:
40-y=12
-y=-28
y=28
So now we have figured out x and y, which are 40 and 28.
What part of an equation represents the constant rate of change?
Answer:
equation written in the form Ax + By = C where A and B are coefficients and C is the constant. assigns each input value, one output value. rate that describes how one quantity changes in relation to another quantity. rate of change between any two quantities is the same, or constant.
