Answer:
y-intercept: -4 or (0, -4)
x-intercept: 3 or (3, 0)
Step-by-step explanation:
4x - 3y = 12
we can convert this to slope-intercept form (y = mx+b) given that m is the slope and b is the y-intercept
4x - 3y = 12
-3y = -4x + 12
y = 4/3x - 4
So the intercept is -4 or (0, -4).
For the x-intercept, we can make the y value 0 to solve for x.
4x - 3y = 12
4x - 3(0) = 12
4x = 12
x = 3
So the x-intercept is 3 or (3, 0).

If csc 0 = 2, find sin 0
Answer:
1/2 (Please read explanation to educate yourself)
Step-by-step explanation:
csc = hyp/opp
sin is the inverse of csc --> sin = opp/hyp
so for csc you have csc(0) = 2/1 and since sin is the inverse then sin(0) = 1/2

15 POINTS PLEASE HELP! It is known that 3 is less than y is less then 7. Find the possible values of the expression:
a) 8y
b)14-2y
Answer:
[tex]a) 8y = 32.\\b)14-2y = 6.[/tex]
[tex]the \: right \: expression \: for \\ 3 \: is \: less \: than \: y \: is \: less \: than \: 7 \: is \\ 3 < y < 7. \\ then \\ y \: can \: be \: any \: value \: form \: (4 \: to \: 6). \\ so \: if \: y = 4. \\ then \\ 8y = 8 \times 4= 32. \\ and \\ 14 - 2y = 14 - 2 \times 4 = 6.[/tex]
The maximum and minimum value of the expressions are -
1 - 8y Max [1] = 48 Min [1] = 32
2 - 14 - 2y Max [2] = 6 Min [2] = 2
What is inequality?
In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
Given is that 3 is less than y is less then 7.
We can write the inequality -
3 < y < 7
Expression 1 : 8y
Maximum value of the expression = Max [1] = 48
Minimum value of the expression = Min [1] = 32
Expression 1 : 14 - 2y
Maximum value of the expression = Max [2] = 14 - 2 x 4 = 14 - 8 = 6
Minimum value of the expression = Min [2] = 14 - 2 x 6 = 14 - 12 = 2
Therefore, the maximum and minimum value of the expressions are -
1 - 8y Max [1] = 48 Min [1] = 32
2 - 14 - 2y Max [2] = 6 Min [2] = 2

A convenience store requires that Ayumi spend $4 or more if she wants to pay using a debit card. Donuts cost $0.80 each. A
bottle of orange Juice costs $1.20. Ayumi payed for 1 orange juice and d number of donuts. Write the equation that represent
the situation.
Answer
1.20+0.80d ≥ 4.00 is the equation. If you are trying to solve for the minimum of donuts she needs to buy so it is over $4.00, then it is 4
Step-by-step explanation:
So in the problem we know she already has bought one bottle of orange juice and needs to buy a certain amount of donuts but we know they are each 0.80 so that will become 0.80d. The 1.20 + 0.80d have to be greater than or equal to 4.00 so she can pay with the debit card and that is why we put the ≥ symbol.
Answer:
.80 × 4 =$3.20
orange juice is $1.20
d =.80×4 +1.20
d=$4.40

Z=3x+3 solve for x.
Z=2+3r solve for x.
Answer:
1. X= 1/3 z -1
2. X= 1/3z + -2/3
Step-by-step explanation:
z=3x+3
Step 1: Flip the equation.
3x+3=z
Step 2: Add -3 to both sides.
3x+3+−3=z+−3
3x=z−3
Step 3: Divide both sides by 3.
3x/3 = z-3/3
Step 1: Flip the equation.
3r+2=z
Step 2: Add -2 to both sides.
3r+2+−2=z+−2
3r=z−2
Step 3: Divide both sides by 3.
3r/ 3 = z-2/3

What is an eqination of the line that passes through the point (-3, -7) and parallel to the line 3x-y=5
I need the y=mx+b
Answer:
y = 3x + 2
Step-by-step explanation:
First you need to change the way the equation is said into a easier form:
y = 3x - 5
Since the line is parallel, you can use the same slope of 3:
y = 3x + b
Now you plug in the coordinates into the equation and solve for b:
-7 = 3 ( -3) + b
-7 = - 9 + b
-7 + 9 = b
2 = b
Now plig this into the equation and you have the answer
y = 3x + 2

Options
The circle at the new location has _____________ the original circle.
- the same center as
- twice the circumference of
- half the radius of
- the same area as
Answer:
the same area as
Step-by-step explanation:
When a circle is translated and reflected, the center of the circle will change; however, its area, circumference, radius and diameter remain the same.
This is so because, translation and reflection only affect the positioning of the circle not the size.
Considering the above analysis, we can conclude that option d answers the question correctly.

Answer:
a) root77
b) 2 root77 / ~17.55 cm^2
Step-by-step explanation:
a) by using Pythagorean Theroem,
a^2 + b^2 = c^2
2^2 + b^2 = 9^2
4 + b^2 = 81
81 - 4 = b^2
77 = b^2
root77 = b
b) 1/2bh is the quation for area thus,
area = 1/2 ( 4 ) ( root77)
area = 2 root77
or area = ~17.55 cm^2
h = [tex]\sqrt{77}[/tex]
A =[tex]2\sqrt{77}[/tex]
Step-by-step explanation:Rules for solving this problem:
Isosceles triangle rules
∠C = ∠ABC = BABecause of isosceles being made up of two right triangles; using the pythagorean theorem we can deduce that
(1/2 x AC)² = BC² - h² (1/2 x AC)² = BA² - h²Area of a triangle

If an object is projected upward from ground level with an initial velocity of 48ft per sec, then its height in feet after t seconds is given by s(t)= -16t^2+48t. Find the number of seconds it will take to reach its maximum height. What is this maximum height? The object will take __ second(s) to reach its maximum height. (Simplify your answer.) The maximum height reached by the object is __ feet. (Simplify your answer.)
Answer:
t = 1.5 s and s(t) = 36 feet
Step-by-step explanation:
The height reached by an object as a function of time t is given by :
[tex]s(t)= -16t^2+48t[/tex] ...(1)
t is in seconds
To find the maximum height, put [tex]\dfrac{dh}{dt}=0[/tex]
[tex]\dfrac{d( -16t^2+48t)}{dt}=0\\\\-32t+48=0\\\\t=\dfrac{48}{32}\\\\t=1.5\ s[/tex]
It will take 1.5 seconds to reach its maximum height.
Put t = 1.5 s in equation (1), such that,
[tex]s(1.5)= -16(1.5)^2+48(1.5)\\\\s(t)=36\ \text{feet}[/tex]
The maximum height reached by the object is 36 feet.
