Answer:
(2x^2 + x-7)/3x+ 3
Step-by-step explanation:
Here, we want to write the following as a single fraction;
2x-1/3 - 2/x + 1
That will be;
(2x-1)(x + 1) -2(3)/3(x+ 1)
= 2x^2+ 2x-x-1-6/3(x + 1)
= (2x^2+x-7)/3(x+1)
= (2x^2 + x-7)/3x+ 3
I need an answer for both of these
Answer:
1. x < -2
2. x < -9
Step-by-step explanation:
1. x + 15 < 13
Minus 15 on both sides.
x + 15 - 15 < 13 - 15
+15 - 15 makes a 0.
x < -2
2. x + 11 < 2
Minus 11 on both sides.
x + 11 - 11 < 2 - 11
+11 - 11 makes a 0.
x < -9
Answer:
1. x < -2
2. x < -9
3. x < 15
Step-by-step explanation:
Treat the < and > symbols as an equals sign to make it less confusing to solve. Then solve for x like you normally would.
1. x+ 15 = 13
subtract 15 from both sides
x=-2, or x < -2
2. x + 11 = 2
Subtract 11 from both sides.
x=-9, or x <-9
3. 19 > x + 4
19 = x + 4
Subtract 4.
15 > x, or x < 15
If anyone could answer this it would be great!!
Answer:
27/8
Step-by-step explanation:
first you would convert -.5 to -1/2 and add everything up by getting the same denominator
Answer:
3.375
Step-by-step explanation:First convert the 2 1/4 and the 1 5/8
then you just add it with the 0.5 or just use a calculator
2 1/4 = 9/4
1 5/8= 13/8
okay now do this ---> 0.5 + 9/4 +13/8 =3.375
write the equation of the line thay passes through the point (2,-1) and has a slope of -3
Answer:
Y = -3x -1
Step-by-step explanation:
Y = mx + b
Y is the y intercept (x,y) always graph on y axis
M is the slope
Answer:
Step-by-step explanation:
use the point slope equation.
y-y1 = m(x-x1)
the point is (x1, y1) = (2, -1)
the slope is m = -3
y+1 = -3( x-2)
y = -3x +6-1
y = -3x +5

The geometric meaning of the word normal is perpendicular.
Answer:
A normal is an object such as a line or vector that is perpendicular to a given object. ... If normal is 90 degree to the surface, that means normal is used in 3D. Perpendicular in that case is more in 2D referring two same entities (line-line) with 90 degree angle between them.

Which equation could be used to solve for a value, x, that is equal to 5 times the sum of x and 12?
x = 5x = 12
5x = x + 12
x = 5(x + 12)
x = x + (5)(12)

Answer:
93.96
Step-by-step explanation:
11.54 (half dollar mass) x 4 half dollars = 45.36
8.1 (dollar coin mass) x 6 dollar coins = 48.6

45.36
+48.6
93.96
Answer: The total mass of the coins in Sari's bag is 93.96 grams.
Step-by-step explanation: The half dollar mass is 11.54 grams × 4 half dollars= 45.36 grams and the dollar coin mass is 8.1 grams × 6 dollar coins=48.6 grams.
So we add half dollar and dollar coin masses: 45.36+48.6=93.96 grams, your total should be 93.96 grams, I hope your answer is very helpful, please mark me as brainliest, and have a happy holidays!!!!!!!!! :D

Swim floats are on sale at sam’s shop. They are marked 30% off of the original price of 18.00. How much will the float cost
Answer:
the cost is now $5.40
Step-by-step explanation:
if 18.00 is 100%, and we need to find the new price we need to make 30% into a decimal. which is 0.3. then we multiply 0.3 times 18.00, and that equals 5.4, but since we are dealing with money the answer would be $5.40.
we multiply if we are trying to find the new amount and we divide to find the old amount.

============================================================
Explanation:
Let's find the slope of the table. This will tell us the rate of change.
m = slope
m = (y2-y1)/(x2-x1)
m = (25250 - 26375)/(2 - 1) .... I used the first two rows
m = -1125/1
m = -1125
The slope of -1125 means the plane's altitude is decreasing at a rate of 1125 feet per minute. This is the descent speed.
Since we're told the initial altitude was 27500 ft, this means b = 27500
This means y = mx+b turns into y = -1125x+27500
x is the number of minutes and y is the altitude at time x
As a way to check this, plug in various x values of the table. You should get corresponding y values that match the table. I'll let you do this part.
------------------
Now plug in y = 16250 and solve for x
y = -1125x+27500
16250 = -1125x+27500
-1125x+27500 = 16250
-1125x = 16250-27500
-1125x = -11250
x = -11250/(-1125)
x = 10
It takes 10 minutes after the descent period has started, for the pilot to get to 16,250 ft.
Since the pilot was contacted at the x = 4 minute mark, this means 10-4 = 6 minutes is the duration needed for the pilot to go from 23,000 ft to 16,250 ft.
