What’s the second step of 2(x+1) =8x-5
Answers
Answer:
2(x + 1) = 8x - 5
assuming you already made the first step, the next step is to distribute the 2
2x + 2 = 8x - 5
if you havent made the first step, above is the first step.
the second step would be to combine like terms by subtracting 2x and adding 5 to both sides
7 = 6x
then you would divide both sides by 6
x = 7/6

What is a Graph?A graph is a display of the ordered pairs of a function.
The orange graph is a parabola and the blue graph is a straight line.
The intersection of both the graphs is at x =1
when x =1 , the orange graph has a value y = [tex]\rm \pm[/tex]2
when x=1, the blue graph has value y = -2
Therefore, the value of the functions has been determined at x = 1.

Answers
The correct option will be the option b i.e., the maximum.
It is given that Joseph is earning an annual salary of $24,895. Later he is offered with an ad.
We have to choose the correct option i.e., the minimum or the maximum he would earn per month if he is paid.
What would be the value if x is added to 40 ?
The value will be 40 + x.
Let's assume Joseph is paid $ x for the ad.
Annual salary of Joseph $24,895.
The salary which he will get after the ad offer will be ;
= 24895 + x
So , the annual salary get's increased after the addition of salary of ad offer.

If the original rectangle has an area of 2 cm squared and the scaled copied has an area of 50 cm squared what is the scale factor used to draw the scaled copy
Answers
Answer:
The scale factor used to draw the scaled copy is a factor of 5
Step-by-step explanation:
Here, we are interested in calculating the scale factor which was used to transition the original rectangle to the new scaled copy.
Firstly, there is a way to relate how the scale factor of the sides relate to the scale factor of the area. What we are saying here is that the scale factor of the sides is never equal to that of the area;
For a 2 cm^2 area let’s say the sides are 1 by 2 ; this gives us an area as said
Now, to get 50cm^2, we can see that the scale factor of both areas is 25 (2 to 50)
So the area has been scaled 25 times the original area. So how has the sides been scaled?
Using a general principle, the scale used to scale the area is the square of the scale used to scale the sides. What are we saying here? if the area is scaled by 4, then the sides are scaled by 2
So in this particular case, the area is scaled by a factor of 25
Now, the scale factor of the sides will be the positive square root of this which is 5
Hence, we can conclude that the sides of the smaller triangles were each multiplied by 5 to arrive at the sides of the bigger one which makes it that the scale factor used to draw the scaled copy is 5
Suppose S is between R and T. Use the Segment Addition Postulate to solve for z.. RS=2z+6, ST=4z−3, RT=5z+12
Answers
Answer:
9
Step-by-step explanation:
If S is between R and T, then RS+ST = RT
Given the following parameters
RS=2z+6,
ST=4z−3,
RT=5z+12
On substituting
2z+6+4z-3 = 5z+12
Collect like terms
2z+4z-5z = 12+3-6
6z-5z = 15-6
z = 9
Hence the value of z is 9
52 regular playing cards are randomly dealt to four players with each players receiving 13 cards. What is the probability that each player will have exactly one ace
Answers
Answer:
The probability is 1/28,561
Step-by-step explanation:
Here, we want to find the probability that each of the players will receive exactly one ace.
In a deck of cards, we have 4 suites of 13 cards each, with each of the suites consisting of 1 ace.
So, the probability of getting an ace for each of the four players will be 4/52 = 1/13
Now, the probability of each of the players getting exactly one ace will be; first got one ace , second got one , third got one and fourth got one.
mathematically, this probability will be 1/13 * 1/13 * 1/13 * 1/13 = (1/13)^4 = 1/28,561
What value of x makes the equation true?
147 = 5(1 - 7x) + 2
Answers
Answer: X = -4
Step-by-step explanation:
first you need to solve, so do what needs to be done in the equation, which is just multiply and add
147 = 5 - 35x + 2
147= 7 -35x
get rid of the numbers around x, which would be subtracting 7 from both sides
140 = -35x
x = -4
