Answer:
-1 or -0.5
Step-by-step explanation:
f(x) is a common phrase you will see a lot in more advanced math.
Think of it as saying "Function of X". So, when you see f(-1), that means the function of x=-1.
So, when it's asking what value X is in f(-1), remember that that number is the x value.
I say COULD BE -0.5 if it means what y is when x = -1. This is if AND ONLY IF you have a check button to see if -1 is right or the wrong answer. I doubt it is, but I want you to be successful in your work.
I hope this helps :)
Solve the simultaneous equations
5x - 4y = 19
x + 2y = 8
Answer:
x= 5 and y = 1.5
Step-by-step explanation:
5x -4y = 19
x + 2y = 8
let x = 8 - 2y...
5x - 4y = 19.......x = 8 -2y
5(8-2y) - 4y = 19
40 - 10y -4y= 19
40-14y = 19
-14y = 19-40
-14y = -21
y = 1.5
x = 8 - 2(1.5)
x = 8 - 3
x = 5
Thus, x is 5 and y is 1.5
Hope this helps!!!!

OPTIONS R NOT HERE
HOPE IT HELP
Answer: i didn't get enough detail but you can use this to help
Step-by-step explanation:
Irrational numbers are the real numbers that cannot be represented as a simple fraction. It cannot be expressed in the form of a ratio, such as p/q, where p and q are integers, q≠0. It is a contradiction of rational numbers.
Irrational numbers are expressed usually in the form of R\Q, where the backward slash symbol denotes ‘set minus’. it can also be expressed as R – Q, which states the difference between a set of real numbers and a set of rational numbers.

What percent is 7 out of 20?
Step-by-step explanation:
35%Therefore, 7/20 in terms of percentage is 35%
Now, let us express 7/20 in terms of decimals. To convert any fraction to a decimal, we divide the numerator by the denominator.

Answer:
m∠y = 50 (Due to A)
m∠x = 50 (Due to F)
Step-by-step explanation:
Due to corresponding angles,
x = y = 50
Also, another thing... You wrote 60 degrees as your answer for the first part, you did a slight miscalculation.
180 - 130 = 50
So the answer for the first part is 50 degrees. However, the reasoning is correct!

Solve: 3x+4 2−6x = −2/ 5
Answer:
(3x + 4)/(2 - 6x) = -2/5
=>5(3x + 4) = -2(2 - 6x)
=> 15x + 20 = -4 + 12x
=> 15x -12x = -4 -20
=> 3x = -24
x = -24/3 = -8

A store sells notepads in packages of 24 and packages of 6. The organizers of a conference needs to prepare at least 200 notepads for the event. Would they have enough notepads if they bought five packages of 24 and fifteen packages of 6 ?
Answer: Yes they would have enough notepads
Step-by-step explanation:
24 * 5 = 120
15 * 6 = 90
120 + 90 = 210
The organizers will have enough notepads if they bought five packages of 24 and fifteen packages of 6.
Given that, a store sells notepads in packages of 24 and packages of 6.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Now, the number of note pads with five packages of 24
24 × 5 = 120
The number of note pads with fifteen packages of 6
15 × 6 = 90
Total number of note pads
= 120 + 90 = 210
Therefore, the organizers will have enough notepads if they bought five packages of 24 and fifteen packages of 6.

Solve B=1/4m(s+z) for s
Answer:
[tex]s = \frac{-mz+4B}{m}[/tex]
Step-by-step explanation:
Step 1: Distribute.
[tex]B = \frac{1}{4}m * s + \frac{1}{4}m * z[/tex] [tex]B = \frac{1}{4}ms + \frac{1}{4}mz[/tex] [tex]\frac{1}{4}ms + \frac{1}{4}mz = B[/tex]Step 2: Subtract 1/4(mz) from both sides.
[tex]\frac{1}{4}ms + \frac{1}{4}mz - \frac{1}{4}mz = B - \frac{1}{4}mz[/tex] [tex]\frac{1}{4}ms = -\frac{1}{4}mz + B[/tex]Step 3: Divide both sides by m/4.
[tex]\frac{1}{4}ms/\frac{m}{4}=(\frac{-1}{4}mz + B)/\frac{m}{4}[/tex] [tex]s = \frac{-mz+4B}{m}[/tex]which is bigger 3/11 or 3/12

[12(x+3)-4]-2(x-1)+6]
10(x + 4)
Step-by-step explanation:
Simplify :
[12(x + 3) - 4] - 2(x - 1) + 6
= [12x + 36 - 4] - 2x + 2 + 6
= 12x - 2x + 36 - 4 + 2 + 6
= 10x + 32 + 8
= 10x + 40
= 10(x + 4)
