For the function y = f(x) = 3x -5
What is the y intersection
Answer:
The y-intercept is -5.
Step-by-step explanation:
In algebra, "y=" and "f(x)=" is basically the same thing. You don't have to write them both. Also, [tex]y=3x-5[/tex] is in slope-intercept form, which is: [tex]y=mx+b[/tex], where [tex]b[/tex] is the y-intercept. That means "-5" is the y-intercept.
In terms of the cosecant of a positive acute angle, what is the expression for csc 240°?
Answer:
- csc60°
Step-by-step explanation:
240° is in the third quadrant where csc < 0 , thus
csc240° = - csc(240 - 180)° = - csc60°
The expression for cosec 240° in terms of the cosecant of a positive acute angle is -cosec 60°.
What is the value of cosec (180°+α)?The value of cosec (180°+α) is -cosec α because (180°+α) lies in the third quadrant and in the third quadrant cosecant is negative.
So, cosec 240° = cosec (180°+60°)
cosec (180°+α) = -cosec α
So, cosec (180°+60°) = -cosec 60°
Thus, the expression for cosec 240° in terms of the cosecant of a positive acute angle is -cosec 60°.

What is 1/5 as a percentage and decimal?
Answer:
1/5 as a percentage:
1/5*100
1/1*20
20/1
20%
1/5 as decimal:
(JUST SIMPLY DIVIDE 1/5)
0.2
Answer:
20% and 0.20
Step-by-step explanation:
Let's say 5/5 = 100, so then in order to convert 1/5 into a percentage, all you have to do is divide 100 by 5, and that will be your percentage:
100 / 5 = 20
So, 1/5 = 20%
Now, as a decimal its basically the same thing, but instead of thinking of it as 100, you think of it as 1.00, and then your decimal form of 1/5 will be 0.20

Alyssa’s lemonade recipe calls for 9 lemons for every 2.5 gallons of water. Brian’s recipe calls for 12 lemons for every 4 gallons of water. Whose lemonade will require more water if they each use 36 lemons? . can you help me
Answer:
Alyssa’s lemonade recipe
Step-by-step explanation:
→ Work out how much lemons is needed per gallon for Alyssa’s lemonade recipe
9 lemons = 2.5 gallons
(÷ 2.5) = (÷ 2.5)
3.6 lemons = 1 gallon
→ Work out how much lemons is needed per gallon for Brian’s lemonade recipe
12 lemons = 4 gallons of water
(÷ 4) = (÷ 4)
3 lemons = 1 gallon of water
→ Now compare
Alyssa’s lemonade recipe ⇒ 3.6 lemons = 1 gallon
Brian’s lemonade recipe ⇒ 3 lemons = 1 gallon of water
Brian's lemonade recipe requires more water.
Alyssa uses 10 gallons of water for 36 lemons. Brian uses 12 gallons of water for 36 lemons. Therefore Brian's lemonade recipe requires more water.

If three quarters of a number decreased by twenty is equal to eighty two, what is that number?
A number is :
[tex]x[/tex]
_________________________________
Three quarters of it means :
[tex] \frac{3}{4}x \\ [/tex]
_________________________________
Decrease by 20 means :
[tex] \frac{3}{4}x - 20 \\ [/tex]
_________________________________
Equals to 82 means :
[tex] \frac{3}{4}x - 20 = 82 \\ [/tex]
_________________________________
What is that number ?
x asked so we must solve the above equation for x.
Let's do it....
[tex] \frac{3}{4}x - 20 = 82 \\ [/tex]
Plus sides 20
[tex] \frac{3}{4}x = 82 + 20 \\ [/tex]
[tex] \frac{3}{4}x = 102 \\ [/tex]
Multiply sides by 4
[tex]3x = 102 \times 4[/tex]
Divided sides by 3
[tex]x = \frac{102 \times 4}{3} \\ [/tex]
[tex]x = \frac{102}{3} \times 4 \\ [/tex]
Simplify
[tex]x = 34 \times 4[/tex]
[tex]x = 136[/tex]
So that number is 136 .

The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.
Winston lives near the ocean. He regularly brings an altimeter to the beach to measure the elevation of the ocean’s surface. You will use the data Winston gathered to complete tasks about the rising and falling of the ocean’s surface. When necessary, sketch a diagram of the situation on a separate sheet of paper to assist you.
On Monday at 1 p.m., when the ocean’s surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.
What was the distance between the deck and the ocean’s surface at 1 p.m.? Which was higher, the deck or the ocean?

a photo collage consists of seven equal sized square photo arranged in a row to form a rectangle if the total area of the college is 567 square inches what is the length of the collage
Answer:
Step-by-step explanation:
I have attached a written explanation to help :).
Let's say each side of the square =[tex]x[/tex]
If we put 7 squares in a row to make the rectangle,
length of the rectangle = [tex]7x[/tex]
Area of a rectangle = length multiplied by width
Area of rectangle = [tex]7x[/tex] multiplied by [tex]x[/tex] = [tex]7x^2[/tex]
We are also told that the total area = 567
So [tex]7x^2 = 567[/tex]
Now solve for [tex]x[/tex].
Divide both sides by 7.
[tex]\frac{7x^2}{7} = \frac{567}{7}[/tex]
[tex]x^2 = 81[/tex]
Then square root both sides to find [tex]x[/tex]
[tex]x = \sqrt{81}[/tex] = 9
Finally, the question asks to find the length of the collage which we said was [tex]7x[/tex] and we know [tex]x = 9[/tex]
Length of collage = [tex]7x = 7[/tex] multiplied by [tex]9[/tex] = ?
y/5-2=-7 what is the solution of the equation.
Answer: mg they left u hanging for some time here hol up,
y=−25
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
y/5-2-(-7)=0
y/5
(y/5 - 2) - -7 = 0
Subtracting a whole from a fraction
Rewrite the whole as a fraction using 5 as the denominator :
2 = 2/1=2.5/5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
y - (2.5/5 5)=y - 10
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
y+25
———— • 5 = 0 • 5
5
Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
y+25 = 0
4.2 Solve : y+25 = 0
Subtract 25 from both sides of the equation :
y = -25

The quadratic equation will be 2x²-12x+1=0.
What is a quadratic equation?Quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given that the roots of the quadratic equation are 1 and 5 and the leading coefficient is 2.
The equation will be written as,
Quadratic equation = 2( x - 1 ) ( x - 1 )
Quadratic equation = 2 ( x² + 4x - 5)
Quadratic equation = 2x² + 8x - 10

HELP PLEASE!!!!!!!
The y-intercept is the value in the equation without the x and the slope is the value in the equation with the x, it would respond to y = 7.5 - 2
What is the Equation of a Line?A line's equation is a unified representation of all of the line's points. Any point on a line will satisfy the equation in its general version, which is of the type ax + by + c = 0. The slope of the line and a point on the line are the two essential elements needed to create the equation of a line.
A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.
The y-intercept is the value in the equation without the x and the slope is the value in the equation with the x, it would respond to y = 7.5 - 2

What we know:
C + 8 = A
A + 5 = B
A + B + C = 72
Charles:
C + 8 + 5 = B
C + (C + 8) + (C + 13) = 72
72 - 8 - 13 = 51
51/3 = 17
Charles scored 17 points.
Bethany:
17 + 13 = 30
Bethany scored 30 points.
Adam:
17 + 8 = 25
Adam scored 25 points.
