Write an equation in point slope form that passes through (-14, - 6) and the
slope is 2/3
Answer:
y=2/3x - 6
Step-by-step explanation:
use the formula y=mx+b. the m of this equation is equal to the slope and you know that the slope is 2/3. the b of the equation is equal to the y-intercept so, to find b you simply look at the points given. the points are written in (x,y) form so if -14 is x, -6 must be y. remember to KEEP CHANGE CHANGE your signs so that plus sign becomes negative 6.

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.

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

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

It says solve each triangle so what parts am I solving? Do I solve all parts or if there’s 2 angles and 1 side, I look for the other angle?
Step-by-step explanation:
Solving a triangle means finding all unknown sides and angles.
For example, in #9, the third angle is 180° − 81° − 59° = 40°.
Using law of sines, the other two sides are:
a / sin 59° = 15 / sin 40°
a = 20.0
b / sin 81° = 15 / sin 40°
b = 23.0
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

Anyone with the answers to unit 1 Geometry basics homework 5 angle relationships
Answer:
Step-by-step explanation:
1) x + 65 = 90
x = 90 -65
x = 25
2) x + 51 = 180 {Linear Pair}
x = 180 - 51
x = 129
3) y = 107 {Vertically opposite angles are equal}
x + 107 = 180 {linear pair}
x = 180 - 107
x = 73
z = x {Vertically opposite angles are equal}
z = 73
4) If sum of two angles is 180,, then they are called supplementary.
one angle = 13
It's supplement = 180 - 13
= 167
5) If sum of two angles is 90, then they are called complementary.
one angle = 38
It's complement = 90 - 38
= 52
6) ∠1 + ∠2 = 180
5x + 9 + 3x +11 = 180 {Combine like terms}
8x + 20 = 180
8x = 180 -20
8x = 160
x= 160/8
x = 20
∠1 = 5x + 9
= 5*20 +9
= 100+9
= 109
∠2 = 3x +11
= 3*20 +11
= 60 +11
= 71
7) Vertically opposite angles are equal
∠2 = ∠2 1
20x - 14 = 17x + 1
20x - 17x -14 = 1
3x - 14 = 1
3x =1 +14
3x = 15
x = 15/3
x = 5
∠2 = 20x - 14
= 20*5 - 14
= 100 - 14
= 86
8) ∠K + ∠L = 90
3x +3 + 10x - 4 = 90 {Combine like terms}
13x -1 = 90
13x = 90 + 1
x = 91/13
x = 7
∠K = 3x + 3
= 3*7 + 3
= 21 +3
= 24
∠L = 10x - 4
= 10*7 -4
= 70 - 4
= 66

Write the fraction 16/40 in simplest form. If the fraction is in simplest form
To covert a fraction to it's simplest form we need to divide their numerator and denominator with the same number .
= 16/40
= 16 ÷ 4 / 40 ÷ 4
= 4/10
= 4 ÷ 2 / 10 ÷ 2
= 2/5
Since both the numerator and denominator dont have a common factor , we can say that they are in their simplest form .
Therefore , the fraction 16/40 = 2/5

Answer:
a) root77
b) 2 root77 / ~17.55 cm^2
Step-by-step explanation:
a) by using Pythagorean Theroem,

Step-by-step explanation:
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
