Answer:
(-2,-4),(2,1), and (7,-5)
Step-by-step explanation:
The given triangle has coordinates (6,4), (2,-1), and (-3,5).
When we translate 4 units left, the we obtain:
(6,4)------>(6-4,4)=(2,4)
(2,-1)----->(2-4,-1)=(-2,-1)
(-3,5)----->(-3-4,5)=(-7,5)
When the resulting figure is rotated 180° about the origin, the coordinates of the final figure becomes
(2,4)------>(-2,-4)
(-2,-1)----->(2,1)
(-7,5)------->(7,-5)
NB: The mapping for 180° rotation is:
(x,y)----->(-x,-y)
Simplify the expression 4x+10+6x+2x
Answer:
12X+10
Step-by-step explanation:
It's easy. Just combine like terms. Like terms must have the same variable and to the same power in this case all the terms have a power of 1, but it doesnt show it because it doesn't really matter. So 4x,6x, and 2x all have the same variable so add them together. That gets you 10x. Since nothing else in the expression has the same variable with 10, you leave the 10 at the end resolving in 12x+10

in a fundraiser, Mrs. Smith pledges $1 for each mile walked . if Sam walks 20 miles how much will Mrs. Smith donate? what is yhe constant proportionality of the problen
Final answer:
Mrs. Smith will donate $20 for Sam walking 20 miles, illustrating a direct proportional relationship with a constant of proportionality of $1 per mile, which is a simple yet effective example of how constants of proportionality function in everyday scenarios.
Explanation:
In the fundraiser mentioned, Mrs. Smith pledges $1 for each mile walked. If Sam walks 20 miles, Mrs. Smith will donate $20. The constant of proportionality in this problem is $1 per mile.
You can see this relationship as a simple formula: total donation = $1 × number of miles walked. So, if we replace "number of miles walked" with 20, the formula would be total donation = $1 × 20 = $20. This illustrates how the initial pledge creates a directly proportional relationship between the money donated and the miles walked.
The constant of proportionality here is crucial because it tells us how much money will be donated per mile that Sam walks. It is a straightforward example of how constants of proportionality work in real-life scenarios, similar to being paid for each call made in a phone drive or being charged per hour of tutoring.

-8=p-13 how do you solve this problem
Answer:
you add -8 to 13
Step-by-step explanation:
-8+13=5
p=5
Answer: 5 = p
Step-by-step explanation: To solve the equation -8 = p - 13, notice that the variable is on the right side of the equation,
don't let this throw you off.
To solve for p, we need to get p by itself on the right side of the equation by adding 13 but if we add 13 to the right side of the equation, we also must add 13 to the left side of the equation.
On the right side of the equation, the -13 and + 13 cancel eachother out and we have p. On the left side of the equation, -8 + 13 is 5 so we have 5 = p which is the solution to our equation.

orange, yellow, green, and blue). Keisha selects 1 marble, looks at it, puts it
back, and then selects another. Find the probability of Keisha first picking a
yellow marble and then an orange marble.
O A. 0.5
O B. 0.008
O c. 0.04
OD. 0.2
Answer:
The answer would be 0.2
Step-by-step explanation:
Because there is five numbers and if you split 1 into five equal parts there is 0.2 which leads to the answer being 0.2
The required probability of Keisha first picking a yellow marble and then an orange marble is 0.04. Option c is correct.
A bag contains marbles and has an equal number of marbles in 5 colors.
The probability of Keisha first picking a yellow marble and then an orange marble is to be determined.
Probability is the ratio of a favorable number of events to the total number of events.
The total number of samples is = 5
Probability for yellow marble = 1/5 = 0.2
Probability for orange marble = 1/5 = 0.2
Probability for first picking yellow than orange = 0.2*0.2
= 0.04
Thus, the required probability of Keisha first picking a yellow marble and then an orange marble is 0.04.

Machine a has a fixed daily cost of $40 and variable cost of one dollar per item produced. machine B has a fixed daily cost of $30 and a variable cost of $1.50 per item produced. A) what is the number of Items X for which the total daily cost C in dollars of each machine will be the same x items? B) what is the total daily cost per machine for this number of items?
To find the number of items, x, for which the total daily cost, C, of each machine will be the same, we can set up an equation and solve for x. The number of items x for which the total daily cost C of each machine will be the same is 20. For 20 items produced, the total daily cost per machine is $60.
Explanation:To find the number of items, x, for which the total daily cost, C, of each machine will be the same, we can set up the following equation:
40 + 1x = 30 + 1.5x
Simplifying, we get:
0.5x = 10
Dividing both sides by 0.5, we find:
x = 20
Therefore, the number of items x for which the total daily cost C of each machine will be the same is 20.
To find the total daily cost per machine for this number of items, we can substitute x = 20 into the equations for each machine:
Machine A: C = 40 + 1(20) = 60
Machine B: C = 30 + 1.5(20) = 60
So, for 20 items produced, the total daily cost per machine is $60.
