Answers
Answer:
(3, -9)
Step-by-step explanation:
5x + y = 7
-x - 2y = - 15
What we can do is multiply the second equation by 5, as we try to combine both equations to get rid of x.
5x + y = 6
-5x - 10y = 75
-9y = 81
y = -9
Now we plug y back in.
5x - 9 = 6
5x = 15
x = 3

Answer:
the answer is d) y = cos(x - Pi) - 2
Step-by-step explanation:
you can see that on the graph that os must be -2.. so you can move it for 2 up
than you have to take in count that (x - Pi) so you move your graph for Pi to the left
and than you have to recognize the function.. if it goes through 0 is sin if not is cos
The equation for the graph y = cos(x - Pi) - 2.
You can see that on the graph that os must be -2.
So you can move it for 2 up.

1. Mrs. Galicia is building a chicken farm in 2021 with an initial population of 3750 chickens. The farm grows at a rate of 2.15% annually.
(a) Use the exponential growth model to write an equation that estimates the population t years after 2021.
(b) Estimate the population of the town in 2036. *please show plug in step*
Answers
Hey there!
a) --›initial number = 3750
--›rate = 2.5%
let y be the population t years after 2021
So, y = 3750(1+2.15) ^ t
=> 3750 × 1.0215 ^ t
b) In 2036,
=> t = 2036 - 2021
=> 15
Substitute into the first value
=> 3750 × 1.0215 ^ t
=> 3750 × 1.0215 ^ 15
=> 5159.
Therefore, the population in 2036 would be 5159

Answer:
75 degrees and 105 degrees.
Step-by-step explanation:
So this is a transversal. We can use a couple different methods to solve this. We can use many different theorems to solve this problem. So we know that m<2=m<4 because of vertical angles, we also know that m<4=m<6 because of alternate interior angles. We also know that m<6=m<8 because of vertical angles. So we know that m<2=m<4=m<6=<8. In a transversal, there are only two different measurements. And those two different measurements add up to 180 degrees. So since once of the measurements is 75, that means the other measurement has to be 105 degrees. Also, we see that m<4 and m<5 are same side interior angles and according to that theorem, they have to equal up to 180 degrees.

Angles A and B are complementary to each other. If mA = 130 + x and mB = 170 + x, what is the value of x?∠∠
Answers
Answer:
-105
Step-by-step explanation:
This means their measures add to 90 degrees, so:
(130+x)+(170+x)=90
300+2x=90
2x=-210
x=-105
The value of x in the expression for the measure of the complementary angle is -105.
What is the numerical value of x?Complementary angles are simply angles that sum up to 90 degrees.
Given the parameter:
Angles A and B are complementary.
Measure of angle A = 130 + x
Measure of angle B = 170 + x
Value of x =?
Since angles A and B are complementary, their sum should be equal to 90 degrees.
Hence:
Angles A + Angle B = 90
Plug in the expressions:
(130 + x) + (170 + x) = 90
Combine like terms:
x + x + 130 + 170
2x + 300 = 90
Subtract 300 from both sides:
2x + 300 - 300 = 90 - 300
2x = -210
x = -210/2
x = -105
Therefore, x has a value of -105.

Assume that based on 2,000 calories per day, you want to choose 1/8 of your daily calories from consuming milk. How many calories am I allowed to get from milk and how many cups per serving?(1 cup of milk has 150 calories)
Answers
Answer:
1.7 cups
Step-by-step explanation:
Firstly, we need to figure out how many calories of milk we are allowed to consume. This would be solved by dividing 2000 by 8 to find 1/8 of 2000.2000 ÷ 8 is 250 calories. With this information, now we can use the information we have about one cup of milk.If one cup of milk is 150 calories and we are allowed to consume 250 calories of milk, we can solve by dividing 250 by 150.250 ÷ 150 is 1.7 cups of milk.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers.
