Answer:
x > π/4Step-by-step explanation:
Given the inequality expression
sin(x)>cos(x)
Divide both sides by cos(x)
sin(x)/cos(x)>cos(x)/cos(x)
tan(x) > 1
x > tan⁻¹1
x > 45⁰
x > π/4
Hence the required solution is x > π/4

Simplify the expression 4(5 - 2)2 – 7.
Answer:
17
Step-by-step explanation:
Remember to solve by the order by operations, or PEMDAS. PEMDAS says that when simplifying an expression, you need to solve parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right) in that order.
1) Knowing this, start by solving what's in the parentheses:
[tex]4(5-2)2-7\\= 4 (3)2-7[/tex]
2) Then - still following the order of operations - multiply the 4, 3, and 2 together.
[tex](4)(3)(2)-7\\(24)-7[/tex]
3) Finally, subtract 7 from 24.
[tex]24-7\\= 17[/tex]
Therefore, 17 is the answer.

Which Expression represents 8 less than 3 times?
Answer:
3x-8
Step-by-step explanation:
if 8 less than something it means subtract, example:
8 less than 21 = 13
and plus u said 3 times x and when multiplying by a variable(letter) you can put them together, example:
3 times x = 3x
The given statement can be written as expression as -
f(x) = 3x - 8
What is a expression? What is a mathematical equation? What do you mean by domain and range of a function?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which [y] exists.
Given is the statement -
8 less than 3 times
We have -
Assume the number to be [x]. Then -
f(x) = 3x - 8
Therefore, the given statement can be written as expression as -
f(x) = 3x - 8

Answer:
C
Step-by-step explanation:
you can see the proportion is right because you get 5 cucumbers for 2 dollars. for double cucumbers times by two which equals 4 dollars. Times 5 by three because it's 3 times bigger meaning it has to equal 6 dollars and finally times 2 by 4 making 20 cucumbers cost 8 dollars.

To solve the problem we must know about fractions.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction [tex]\frac{1}{4}[/tex] can be described as 0.25
What is a Mixed Fraction?A mixed fraction is a fraction that contains a whole number and a fraction whose denominator is greater than the numerator.
The solution to this problem is [tex]5\dfrac{13}{40}[/tex].
Given to us
[tex]8\frac{1}{5}-2\frac{7}{8}[/tex]
Converting the mixed fractions to fraction
[tex]8\dfrac{1}{5}-2\dfrac{7}{8}\\\\=\dfrac{(8 \times 5)+1}{5}-\dfrac{(8\times 2)+7}{8}\\\\=\dfrac{41}{5}-\dfrac{23}{8}\\\\[/tex]
Taking LCM,
[tex]=\dfrac{41\times 8}{5\times 8}-\dfrac{23\times 5}{8\times 5}\\\\=\dfrac{328}{40}-\dfrac{115}{40}\\\\=\dfrac{328-115}{40}\\\\=\dfrac{213}{40}[/tex]
Converting to Mixed Fractions,
[tex]=5\dfrac{13}{40}[/tex]
Hence, the solution to this problem is [tex]5\dfrac{13}{40}[/tex].

Answer:
-2 due to the y axis having the line run through the -2
Answer:
Y-intercept is -2. Equation is y=1x-2
Step-by-step explanation:
#NotATest.
You probably don't want an explanation.
The y-intercept is -2 because that is where the line meets the y-axis.
The slope is 1 because the line is going up 1 unit, and over 1 every time.
The last part is -2 because that is the y-intercept.

SOLVE FOR X, WILL GIVE BRAINLIEST
-- these are called same side interior angles, which are supplementary.
to solve for x:
3x + 37 + 2x - 7 = 180
5x + 30 = 180
5x = 150
x = 30
Answer: x = 30
========================================================
Explanation:
These angles shown are same side interior angles.
Due to the parallel lines, same side interior angles are always supplementary.
This means they add to 180
(2x-7)+(3x+37) = 180
2x-7+3x+37 = 180
(2x+3x)+(-7+37) = 180
5x+30 = 180
5x = 180-30 .... subtracting 30 from both sides
5x = 150
x = 150/5 ... dividing both sides by 5
x = 30
