[tex]1140[/tex]
Step-by-step explanation:
[tex](−57)×(−19)+57 \\ =1083+57 \\ =1140[/tex]
Hope it is helpful....Answer:
1140
Step-by-step explanation:
1. you first need to distribute -57 to -19 as they are being multiplied
(-57) · (-19) + 57
(1083) + 57
2. now you remove the parenthesis and add the liked terms
1083 + 57 = 1140

Which equation represents a population of 490 animals that increases at an annual rate of 20% ?
Answer:
Step-by-step explanation:
The standard form of this exponential function is
[tex]y=a(b)^x[/tex] where a is the initial value and b is the growth rate. Our initial value is 490 and our growth rate is .2 so the equation is
[tex]y=490(.2)^x[/tex]

9. Tobias ran 3 miles. How many millimeters did he run? (1 mile = 1,610 meters)
Welcome to Brainly! I'm happy to help!
We see that there are 1,610 meters in a mile. However, we are looking for millimeters, not meters. But, knowing the meters will help us out.
A millimeter is a very small measurement. There are 1,000 millimeters in 1 meter. A meter is much larger. So, if we want to convert 1,610 meters to millimeters, there are going to be way more millimeters because they are so minute.
This means that we will have to multiply. We know that there are 1,000 millimeters in 1 meter, so if we multiply our meters by 1,000 (which is basically just adding 3 zeros), we will get the number of millimeters in one mile!
1,610×1,000=1,610,000 (one million six hundred and ten thousand!)
Don't forget that we are looking for 3 miles though, so we can take the number of millimeters in one mile and multiply by three.
1,610,000×3=4,830,000 (four million eight hundred and thirty thousand!)
So, Tobias ran 4,830,000 millimeters!

Which kind of function best models the data in the table? Graph the data and write an equation to model the data.
A. linear; y = x – 1
B. quadratic; y = x2 – 1
C. exponential; y = 3x – 1
D. linear; y = –x – 1
Answer:
D. linear; y = –x – 1
Step-by-step explanation:
Linear; y=-x - 1
The slope is negative since it’s decreasing. So it’s not the first equation. It’s not a quadratic equation because there is no forming U shape for this data. It’s not a exponential function because the slope is not 3 and a exponential function is in the form y=a(b)^x
Answer:
The correct answer is D) linear; y = –x – 1
Step-by-step explanation:
To find this, use any values in the table and it will produce a true statement. This is how we check to see if a model is correct. See the two examples below for proof.
(4, 5)
y = -x - 1
-5 = -4 - 1
- 5 = -5 (TRUE)
(0, -1)
y = -x - 1
-1 = 0 - 1
-1 = -1 (TRUE)
Please help me I’ll give a brainly! It’s due soon!
Hi! I'm happy to help!
First, we need to get our two equations, so we need to look at what facts we have throughout the equation. It tells us that x is 3 times as much as y. We can use this to write our first equation:
3y=x
All of the interior angles inside of a triangle add up to 180°, and because we already have 3 angles, we can use this information to make our second equation:
x+y+45=180
Now, we have to use these equations together to get our answer.
Since we can replace 3y for x (first equation) we can replace it in our second equation:
3y+y+45=180
We edit both sides of the equation in the same way to get the same outcome, but to simplify. Since we are solving for y, let's isolate it by subtracting 45 from both sides:
3y+y+45=180
-45 -45
3y+y=135
Let's combine the 3y and y to make things simpler:
4y=135
From here, we divide both sides by 4, to isolate y:
y=33.75
Now that we have our y value, we can use our first equation to solve for x:
3y=x
3(33.75)=x
101.25=x
We used our equations to get both our x and y values: 33.75, and 101.25.
I hope this was helpful, keep learning! :D

find the sum of first 50 terms in the sequence 10n-15.
Answer:
485 bro just do it with calculator
Step-by-step explanation:
10×n-15
10×50-15
485
Answer:
12,000.
Step-by-step explanation:
First term = 10(1) - 15 = -5
50th term = 10(50) - 15 = 485
Sum of 50 terms = (50/2)(-5 + 485)
= 25 * 480
= 12,000

Is the expression 2•4 equal to the expression 8x? Explain your answer
9514 1404 393
Answer:
no
Step-by-step explanation:
The expression 2·4 has the value 8.
The expression 8x has the value 8x, which is only equal to 8 when x=1. In general, x may have any value, so the expressions are not equal.
Find the constant of proportionality (r) in the equation y=rx
Answer:
r = [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Given the proportional equation
y = rx ← r is the constant of proportion
Divide both sides by x
[tex]\frac{y}{x}[/tex] = r
Use any ordered pair from the table.
Using (8, 2 ) , then
r = [tex]\frac{2}{8}[/tex] = [tex]\frac{1}{4}[/tex]
Answer:
1/4
Step-by-step explanation:
Multiplying the input (x) by (1/4) results in the output. This is direct proportion, and the constant of proportionality is (1/4).

Line RS bisects segment PQ at R. If RQ = x + 9 and RP = 2x, find PQ.
Answer:
PQ measures 36 units.
Step-by-step explanation:
Line RS bisects segment PQ at R. By the definition of a bisector:
[tex]\displaystyle PR = RQ[/tex]
Hence:
We are given that RQ = x + 9 and RP = 2x, and we want to determine PQ.
Solve for x. Substitute:
[tex]\displaystyle (2x) = (x+9)[/tex]
Hence:
[tex]\displaystyle x = 9[/tex]
PQ is given by:
[tex]\displaystyle PQ = PR + RQ[/tex]
Since PR = RQ:
[tex]\displaystyle PQ =2PR[/tex]
Substitute and evaluate:
[tex]\displaystyle \begin{aligned} PQ &= 2PR \\ &= 2(2x) \\ &= 4x \\ &= 4(9) \\ &= 36 \end{aligned}[/tex]
Hence, PQ measures 36 units.

what is the solution to the compound inequality in interval notation
Answer:
First choice is the right answer (-∞, -9] or (2, ∞)
Step-by-step explanation:
I. Solve 1st problem 2(2x - 1) > 6
4x-2 > 6
4x > 6+2
x > 2
II. Solve 2nd problem x + 3 <= -6
x <= -6-3
x <= -9
III. Prove the answer
if x > 2 then x = 3
2( 2(3)-1 ) > 6
2(5) > 6
10 > 6 so the answer is true
if x <= -9 then x = -9
-9 + 3 <= -6
-6 <= -6 so the answer is true

A shopkeepers bought 500 glass tumblers at rs 40 each . 20 glass tumblers were broken and he sold the rest at rs 45 each. Find his profit or loss percent
if you will solve this questions in copy and send me pictures of the answer then it will be very helpful for me please
500 at 40 each = £20000
To make a profit he needs to make more than £20000
20 broke so he sold 500-20 = 480 at 45 each.
480 x 45 = 21600
Profit = 21600 -20000 = 1600
His profit was £1,600

Together, Sala and Terry saved $10.00. Sala. saved D dollars. Write an expression for the amount Terry saved.
Let Terry Saved be T dollars .
The Expression will be
[tex]\\ \rm\longmapsto Sala+Terry=\$10.00[/tex]
[tex]\\ \rm\longmapsto D+T=\$10.00[/tex]
Answer:
T = 10 - S
Step-by-step explanation:
The only useful information is that they saved $10 together. We are just going to add the money Sala and Terry saved to equal 10.
S + T = 10
They want an expression for how much Terry saved so we can solve for T.
T = 10 - S
Best of Luck!
