Which equation in point-slope form contains the point (4, –1) and has slope 3?
y + 1 = 3(x – 4)
y – 4 = 3(x + 1)
y – 1 = 3(x + 4)
y + 4 = 3(x – 1)
Answer:
y+1=3(x-4)
Step-by-step explanation:
Hi there!
We are given a slope of 3 and a point (4,-1).
We need to find the equation of the line in point-slope form
Point-slope form is given as y-y1=m(x-x1), where m is the slope, and (x1,y1) is a point
We have all of the needed information to substitute into the formula
First, let's label the values of everything to avoid any confusion
m=3
x1=4
y1=-1
now substitute into the formula *remember, the formula has SUBTRACTION, and we have a NEGATIVE number, so we'll end up subtracting a negative*
y--1=3(x-4)
simplify
y+1=3(x-4)
That's it!

Identify the explicit function for the sequence in the table x 1,2,3,4,5 y 9,14,19,24,29
Answer:
[tex]a_{n}[/tex] = 5n + 4
Step-by-step explanation:
There is a common difference between the consecutive terms of y
29 - 24 = 24 - 19 = 19 - 14 = 14 - 9 = 5
This indicates the sequence is arithmetic with explicit formula
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 9 and d = 5 , then
[tex]a_{n}[/tex] = 9 + 5(n - 1) = 9 + 5n - 5 = 5n + 4

Lucia is making blackberry jam. She starts with 25 cartons of blackberries. After making 9 jars of jam, she has 10 cartons of blackberries left. Lucia's jars all have the same capacity. Select true or false for each statement.
Answer:
A = true
B = false
C = false
D = True
Step-by-step explanation:
Cartons of blackberries = 25
Jars of blackberry jam made = 9
Cartons of blackberries left = 10
Cartons of blackberry used = Cartons of blackberries - Cartons of blackberries left
= 25 - 10
= 15
Cartons of blackberry used = 15
Cartons of blackberry used per jam = Cartons of blackberry used / Jars of blackberry jam made
= 15/9
= 5/3
A = true
15 jars of blackberry = Cartons of blackberry used per jam × jars of black berry made
= 5/3 × 15
= 75/3
= 25 cartons of blackberry
B = false
She can make 15 jars of blackberry jam using 25 cartons of blackberry
C = false
Cartons of blackberries left = 10
Number of blackberry jam made with 10 cartons of blackberry = Cartons of blackberries left / Cartons of blackberry used per jam
= 10 ÷ 5/3
= 10 × 3/5
= 30/5
= 6

Answer:
(6x + 5)(x + 2)
Step-by-step explanation:
x coefficients must multiply to 6
so 6 * 1 or 2*3
10 must be 5*2 or 1* 10
(6x + 5)(x + 2) = (6x² + 12x + 5x + 10) = 6x² + 17x + 10
For the triangles to be similar by the SSS similarity theorem, what must be the value of y?
18
20
24
26
Answer:
20
Step-by-step explanation:
Took the cumulative exam on Edge
The value of y in the given similar triangles is 20.
What are the similar triangles?Two triangles are said to be similar if their corresponding angles are congruent to each other and the corresponding sides are in equal ratios.
Given are two triangles, we need to find the value of y so that the triangles be similar by SSS rule,
If the figures are similar by SSS Similarity Theorem, then the ratio of its corresponding sides must be proportional,
So,
14/28 = 10/y
y = 20
Hence, the value of y in the given similar triangles is 20.

Answer: t=-3h+25
Step-by-step explanation:
t=-3h+25
25 degrees is a constant-- it never changes, no matter how many hours goes by. So, you don't multiply a variable with it.
The temperature drops every 3 hours-- this is not constant, since it's dependent on the number of hours that passes. So, use a variable here. Since the temperature drops every three hours, it's -3, and not 3.
Answer:
[tex]t=-3h+25[/tex]
Step-by-step explanation:
If we know that when [tex]h=0[/tex], [tex]t=25[/tex], then we can use a direct proportion equation ([tex]x=ky[/tex]). The temperature decreases every hour by 3 degrees. However, we know that before any temperature drop, the temperature was 25 degrees. All together, this gives us [tex]t=-3h+25[/tex], where [tex]-3h[/tex] is the temperature drop each hour, and [tex]25[/tex] is the starting temperature. Hope that explained things :)

A 525ft cable runs from the top of an antena to the ground. The angle of elevation made by the ground to the top of an antena 25°
How tall is the antena ??
Answer:
221.87 feet
Step-by-step explanation:
Given that,
A 525 ft cable runs from the top of an antenna to the ground.
The angle of elevation made by the ground to the top of an antena 25°
We need to find the height of the antenna.
Using trigonometry,
Hypotenuse, H = 525 ft
θ = 25°
So,
[tex]\sin\theta=\dfrac{P}{H}\\\\P=H\sin\theta\\\\P=525\times \sin(25)\\\\P=221.87\ ft[/tex]
So, the height of the antenna is equal to 221.87 feet.
Which equation shows a line with the
slope of 5 that passes through point (2, -3)?
Answer:
y = 5x - 13
Step-by-step explanation:
point slope form: y - y1 = m (x - x1)
plug in: y1 = -3, x1 = 2, m = 5
y - (-3) = 5 (x - 2)
y + 3 = 5x - 10 <- simplify and expand
y = 5x - 13 <answer for slope intercept
equation: y = 5x - 13
I'm not sure what equation type you would like as well as your possible answer choices, but I hope this helps!

Answer: The value of x can be either 5 or 10.
Step-by-step explanation:
We are given:
Total profit, P = $5600
The given equation follows:
⇒ P = 600 + 1500x - 100x²
Putting value of P in above equation, we get:
⇒ -100x² + 1500x + 600 = 5600
⇒ -100x² + 1500x - 5000 = 0
⇒ 100x² - 1500x + 5000 = 0
Solving this equation by middle term split, we get:
⇒ 100(x² - 15x + 50) = 0
⇒ (x² - 10x - 5x + 50) = 0
⇒ x(x - 10) - 5(x -10) = 0
⇒ (x - 10)(x - 5) = 0
⇒ x = 10, 5
Hence, the value of x can be either 5 or 10.
