Answer:
x=0 x=8 x = -1/10
Step-by-step explanation:
- 2x(x − 8)(10x + 1) = 0
Using the zero product property
-2x =0 x-8 = 0 10x+1= 0
x= 0 x= 8 10x = -1
x=0 x=8 x = -1/10

what is the answer to -22/9r = 11/9
Answer:
2
Step-by-step explanation:
for this question you've to cross multiply
-22/9r=11/9
99r=-198
then you divide both sides by 99 inorder to remain with r on one side
99r/99=198/99
r=2

(I think I remember your other information correctly.)
Step-by-step explanation:
I think you said you were given
*Integral from x=-5 to x=0 of g was -14
*Integral from x=-5 to x=6 of g was 6
Asked to find integral( g(x) + 2 , from x=0 to x=6)
Yes this can be split into two integrals:
Integral(g(x), x=0 to x=6) + Integral(2, x=0 to x=6)
The last integral is easier... the antiderivative or 2 is 2x. So evaluate 2x as the limits and subtract. Always plug in the top limit first. 2(6)-2(0)=12-0=12
Let's start with the bigger interval from x=-5 to x=6 which was 6... and since we want to get rid of the interval from x=-5 to x=0 to find the integral of g from x=0 to 6, all we must do is do 6-(-14)=20.
Integral( g(x) + 2 , from x=0 to x=6)
=
Integral(g(x), x=0 to x=6) + Integral(2, x=0 to x=6)
=
20+12

Given a positive integer N. Deleting the last digit of N decreases it by 2021. What is N ?
The value of the positive integer N, such that deleting its last digit decreases it by 2021, is 2245. That is, [tex]N=2245[/tex].
Given: A positive integer N such that deleting the last digit of N decreases it by 2021
To find: The value of N
Let x be the integer consisting of all digits of N except the last digit and let the last digit of N be d.
Then, [tex]N=10x+d[/tex]
It is given that deleting the last digit decreases it by 2021
Then, [tex]x=N-2021[/tex]
Substitute [tex]N=10x+d[/tex] in [tex]x=N-2021[/tex] to get,
[tex]x=10x+d-2021[/tex]
[tex]d=2021-9x[/tex]
Since d is a digit, we have,
[tex]0\leq d\leq 9[/tex]
Substitute [tex]d=2021-9x[/tex] in [tex]0\leq d\leq 9[/tex] to get,
[tex]0\leq 2021-9x\leq 9[/tex]
[tex]9x\leq 2021\leq 9x+9[/tex]
[tex]9x\leq 2021\leq 9(x+1)[/tex]
[tex]x\leq \frac{2021}{9} \leq x+1[/tex]
[tex]x\leq 224.5556 \leq x+1[/tex]
Then,
[tex]x\leq 224.5556[/tex] and [tex]224.5556 \leq x+1[/tex]
[tex]x\leq 224.5556[/tex] and [tex]x\geq 223.5556[/tex]
[tex]223.5556 \leq x \leq 224.5556[/tex]
Since x is an integer, the only possibility that satisfies the above inequality is, [tex]x=224[/tex]
Substitute [tex]x=224[/tex] in [tex]d=2021-9x[/tex] to get,
[tex]d=2021-9(224)[/tex]
[tex]d=2021-2016[/tex]
[tex]d=5[/tex]
Substitute [tex]x=224[/tex] and [tex]d=5[/tex] in [tex]N=10x+d[/tex] to get,
[tex]N=2245[/tex]
Thus, the value of the positive integer N, such that deleting its last digit decreases it by 2021, is 2245. That is, [tex]N=2245[/tex].

the Answer is irrational number
How do you do this TwT
Answer:
Step-by-step explanation:
First step plug the numbers into the equation.
-10/(5+2) = (-10/5) + (-10/2)
Solve both sides of the equation separately.
-10/(5+2) Use distributive property, multiply both 5 and 2 by -10.
= -50 + (-20) = -70
-10/5 + -10/2 Multiply the fractions so they can be added together.
-10/5*2 = -20/10 -10/2*5 = -50/10
-20/10 + -50/10 = -70
Now you have solved both equations and they are both equal to -70, so you have verified that the equations are equal to each other because they both equal -70.

find LCM of 60,40 and 90
Answer:
Step-by-step explanation:
Prime factorize.
60 = 2 *2 * 3 * 5 = 2² * 3 * 5
40 = 2 * 2 * 2 *5 = 2³ * 5
90 = 2 * 3 * 3 * 5 = 2 * 3² * 5
LCM = 2³ * 3² * 5 = 8 * 9 * 5 = 360

It is 5 cm between two buildings on a map that has a scale of 100 000:1. What is their actual
distance apart?
O A.
0.5 km
B. 50 km
C.
5 km
OD.
500 km
Answer:
C 5 km
Step-by-step explanation:
so, 5 cm on the map correlates to
5×100000 = 500000 cm in reality.
100 cm = 1 m
1000 m = 1 km
so, 500000 / 100 = 5000 m.
5000 / 1000 = 5 km
Find the measure of the missing angles.
100°
b =
C=
Answer:
<b = 80
<c = 80
Step-by-step explanation:
<b and 100 form a straight line so they add to 180
<b +100 =180
<b = 180-100
<b = 80
angles b and c are vertical angles and vertical angles are equal
<c = <b = 80

Find angle CBA
pls help
Answer:
40
Step-by-step explanation:
u can draw a line at point c parallel to line ab
angle at d and lower part of c is interior angle so u can find the value at lower part of c that is 180-145=35
so point c 75-35=40 is upper part of point c
upper part of c and angle b is alternate angle so both angle are the same
angle cba is 40
Answer:
<CBA = 40°
Step-by-step explanation:
If AB is parallel to DE, you can make an irregular pentagon by continuing AB and drawing a line perpendicular to DE. The sum of the interior angles of a pentagon is 540. You can use this to solve for the supplement of <CBA, then subtract that from 180. (I’m sure there’s an easier way, but I cant think of one right now).
540-90-90-145-75=x
140=x
<CBA=180-140= 40°
