Select the solution(s) to the following equation: (3x−2)(x+5)=0 SELECT ALL THAT APPLY
x=3/2
x=5
x=-5
x=2/3
x=-2/3
x=-3/2
Answer:
Step-by-step explanation:
Check by direct substitution. If we begin by checking x = 3/2, we substitute 3/2 for x in (3x - 2)(x + 5), obtaining (9/2 - 2)(3/2 + 5), which is NOT zero. Therefore x = 3/2 is not a solution.
(3*5−2)(5+5)=0 False. x = 5 is not a solution.
(3*[-5]−2)([-5+5)=0 True. x = -5 is a solution
x = 2/3: (3*2/3 - 2)( ) = 0. True x = 2/3 is a solution
x = -2/3: ( )( ) = -17 1/3; so x = -2/3 is not a solution
x = -3/2: ( ) ( ) = -22 3/4; so x = -3/2 is not a soution

Answer:
The solution of the given inequality
x > 10
Step-by-step explanation:
Step(i):-
Given inequality
3 ( x-8) > -4 + x
Multiply
3 x - 24 > -4 +x
subtract 'x' on both sides , we get
3 x - 24 - x > - 4 + x - x
⇒ 2 x - 24 > - 4
Step(ii):-
Adding '2'4' on both sides , we get
⇒ 2x - 24 + 24 > -4 +24
⇒ 2 x > 20
Dividing '2' on both sides , we get
[tex]\frac{2x}{2} > \frac{20}{2}[/tex]
x > 10
Final answer:-
The solution of the given inequality
x > 10
Express 49 1/2 in simplest radical form.
Answer:
[tex]\sqrt{49}[/tex]=7
The value of the square root of the number 49 is 7.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs. An nth root of a number x is a number r that when raised to the power n yields x.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the number is 49 and the square of the number is calculated as,
E = √49
E = √ ( 7 x 7 )
E = 7

Answer:
A=35, B=55, and C=25
Step-by-step explanation:
Angle A and the angle next to it are linear pairs, so you can subtract 145 from 180.
if you already know Angle A, and that the other angle is 90 degress, you can add 90+35 and subtract it from 180 to get Angle B
Angle C is paired with the angle across from it (I forgot what the term is called) so it is 25 degrees.
which is an equation of the line
a. y = x - 1
b. y= x + 1
c. y= -x -1
d. y= -x + 1
Answer:
the form is y = mx + b an db is the y intercept. the y intercept is 1 so it is not a or c. The slope is positive, so it is b!!!

Forty students went on a trip on Wednesday. On Thursday, 15% less students went on a similar trip. How many students went on the trip on Thursday?
Answer:
34
Step-by-step explanation:
40 * .15= 6
40-6 = 34
okkk so you do 40 * .15 because you just put a decimal point before all percentages to convert it into number
40*.15= 6
then subtract 6 to the original amount
40-6=34
34 students went on the trip on thursday cause 6 students got killed by bears in the last trip.
