Answer: X= -3
Step-by-step explanation: If f(x)= 3x-1
then you would do the math 3x-1= -10
which makes out to be x= -3
1) 5x - 100 x=25 2) x³ x=4 3) 2x - 20 x=5 4) 7x + 25 x=4 5) x³ + 9 x=3. 6) 4(x-5) x=20 7) 6x + y² x= 4 and y= 3
please help asap my parents took away everything and expect me to finish all of this with nothing! help! ily!
Answer:
1) 25
2)64
3)-10
4)53
5)36
6)60
7)33
Step-by-step explanation:
Substitute
1) 5(25)-100
125-100=25
2) 4*4*4=64
3)2(5)-20
=10-20
-10
4)7(4)+25
28+25
53
5) (3*3*3)+9
27+9
36
6) 4(20-5)
4(15)
60
7)6(4)+(3*3)
24+9
33
Step-by-step explanation:
For all of these problems, we are given the values of the variable x.
Now, we just need to input them into the equations.
1) 5x-100 x=25
5(25)-100
125-100= 25
2) x^3 x=4
4^3= 4×4×4= 64
3) 2x-20 x=5
2(5)-20
10-20= -10
4) 7x+25 x=4
7(4)+25
28+25= 53
5) x^3+9 x=3
3^3+9= (3×3×3)+9
27+9= 36
6) 4(x-5) x=20
4(20-5)
20(4)-5(4)
80-20= 60
7) 6x+y^2 x=4 and y=3
6(4)+3^2
24+(3×3)
24+9= 33
Hope this helps! :)

What are the coordinates of the vertex for f(x) = x2 + 4x + 10? (1 point) (−2, 2) (2, 2) (−2, 6) (2, 6)
Answer:
A or C
Step-by-step explanation:
x = x2 + 4x + 10
x = 6x + 10
-5x = 10
x = -2

Help Asap!! Name The Angle Pair And Find The Missing Value .
Answer: Step-by-step explanation:
Supplementary Angles. (Linear Pair)
111 + 3x + 3 = 180
Add 111 and 3 together
114 + 3x = 180
Subtract 114
3x = 66
Divide by 3
x = 22
Answer:
Two angles are called supplementary when their measures add up to 180 degrees. And x=22
Step-by-step explanation:
if you enter 22 in as x and times it by 3 and add 3 to it you get 69 add 111 you get 180 therefore it is supplementary and x=22
6. Which measurement is closest to the value of x?
x cm
5 cm
12 cm
To find the value of x, let us use the pythagoras theorem .
According to the pythagoras theorem, the square on the hypotenuse will be equal to the sum of the squares on the other two sides .
Which means :-[tex] = {5}^{2} + {12}^{2} = {x}^{2} [/tex]
[tex] = 25 + 144 = {x}^{2} [/tex]
[tex] = 169 = {x}^{2} [/tex]
[tex] = 13 \times 13 = x \times x[/tex]
[tex]\color{olive} x = \color{hotpink}13 \: \: cm[/tex]
The measurement which is closest to the value of x, is 12 cm, so the right answer would be 12 cm .
Therefore , the measurement which is closest to the value of x is :-
[tex] \boxed{ \: \bold\color{plum}12 \: \: cm \: }[/tex]

Step-by-step explanation:
Container A and container B have leaks. Container A has 800 mL of water, and is leaking 6mL per minute. Container B has 1000 mL, and is leaking 10mL per minute. How many minutes, m, will it take for the two containers to have the same amount of water?
Answer:
x = 50 minutes
Step-by-step explanation:
GIven:
Container A contain = 800 mL
Container B contain = 1,000 mL
Container A leak = 6 mL per min
Container B leak = 10 mL per min
Computation:
Assume; in x minute
So,
800 - 6x = 1,000 - 10x
4x = 200
x = 50 minutes
When a certain number is multiplied by 12, the product is 120. What is the number? Let s = the number.
Answer:
s = 10
Step-by-step explanation:
you can solve this by the equation 120 / 12 = s. S = 10. so when you do the opposite and multiply 10 by 12 you get 120. Hope this helps.
