Answer:
x-intercept: -6 (-6,0 if you need full coordinates)
y-intercept: -4 (0,-4 for full coordinates)
Step-by-step explanation:
I'm in a rush but ask if you need steps
Answer:
a) y = -(2/3)x - 4
b) x-intercept = -6
y-intercept = -4
Step-by-step explanation:
Slope intercept form is
y = mx + b
4x + 6y + 24 = 0
Subtract 4x + 24 from both sides
6y = -4x - 24
Divide both sides by 6
y = -(2/3)x - 4
-------------------------------------
X intercept
at the x intercept y = 0
0 = (-2/3)x - 4
add (2/3) x to both sides
(2/3)x = - 4
Multiply both sides by 3/2
x = -12/2
x = -6
----------------------------
Y intercept
at the y-intercept x = 0
y = -(2/3)0 - 4
y =-4
A pet store has two tanks of tropical fish. The first tank contains 5 blue fish and 2 yellow fish and the second tank contains 7 blue fish and 2 yellow fish. If Keisha randomly purchases a fish from each tank, what is the probability that both fish will be blue?
Answer:
It would be B
Step-by-step explanation:
You need to add them both together and then once you do that divide everything and you'll get the answer of b.
Find the median and mean of the data set below:
21,0,36,30,13,32
Answer:
Mean: 22
Median: 25.2
Step-by-step explanation:
The mean is the sum of all the numbers in a set divided by the number of terms in a set.
The median is the middle value of the numbers when the numbers in a set are arranged from least to greatest. If there is two middle numbers, the median is the average of the two numbers.

a point in rectangular coordinates is given. Convert the point to polar coordinates. Round your answers to two decimal places.
(5,7)
Answer:
(√74, 54.46°)
Step-by-step explanation:
The rectangular coordinate point is given as; (5, 7)
Now, converting rectangular coordinates to polar coordinates is done by;
(r, θ)
Where, r is the magnitude while θ is the angle
r = √(5² + 7²)
r = √74
tan θ = (7/5)
θ = tan^(-1) 1.4
θ = 54.46°
Thus,polar coordinate is; (√74, 54.46°)

Express the lcm of 50,18 and 32 in prime factors
Answer:
The least common multiple of 50, 18 and 32 is 7200.
Step-by-step explanation:
mark brainleist plz
Answer:
LCM = 7200
Step-by-step explanation:
LCM(18, 32, 50) =
LCM(LCM(18, 32), 50)
Working from the innermost parentheses outward:
LCM(18,32) = (18 × 32) / GCF(18,32)
= (18 × 32) / 2
= 576 / 2
= 288
LCM(288,50) = (288 × 50) / GCF(288,50)
= (288 × 50) / 2
= 14400 / 2
= 7200
Therefore,
LCM(18, 32, 50) = 7200

Answer:
r = 5
Step-by-step explanation:
(r + 8)^2 = r^2 + 12^2
r^2 + 16r + 64 = r^2 + 144
16r = 80
r = 5
Answer:
r = 5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle ABC
AC² = BC² + AB²
(r + 8)² = r² + 12² ← expand left side using FOIL
r² + 16r + 64 = r² + 144 ( subtract r² from both sides )
16r + 64 = 144 ( subtract 64 from both sides )
16r = 80 ( divide both sides by 16 )
r = 5

Anne is 3m away from Ishan at a bearing of 100°. Katniss is 7m away from Anne at a bearing of 260°. By plotting the postitions Anne and Katniss ( using a scale of 1cm : 1m), estimate the distance of Katniss from Ishan.
Answer:
The distance of Katniss from Ishan is approximately 4.305 meters
Step-by-step explanation:
The distance between Anne and Ishan = 3 m
The bearing of Ann from Ishan = 100°
The distance between Anne and Katniss = 7 m
The bearing of Ann from Katniss = 260°
From the diagram of the bearing created with MS Word, let 'a' represent the distance between Ishan and Katniss, let 'b' represent the distance between Ishan and Anne and let 'c' represent the distance between Katniss and Anne, by cosine rule, we have;
b = 3 m
c = 7 m
∠A = 20°
a² = b² + c² - 2·b·c·cos(A)
a² = 3² + 7² - 2 × 3 × 7 × cos(20)
a = √(3² + 7² - 2 × 3 × 7 × cos(20)) ≈ 4.305
By calculation, the distance from Ishan to Katniss, a ≈ 4.305 m
By measurement on MS Word, the distance from Ishan to Katniss, a = √(1.783² + 3.976²) ≈ 4.357.

Answer:
Step-by-step explanation:
First of all it should be like fractions
So -2/3 becomes -10/15
and -3/5 becomes -9/15
-9/15 is greater than -10/15
-3/5 is greater than -2/3
Answer:
-2/3 < -3/5
Explanation:
to convert the fractions to equivalent forms, we need to make sure that they have the same denominator (number on the bottom). the lowest common multiple of both 3 and 5 is 15, hence:
-2/3 = -10/15 (×5)
-3/5 = -9/15 (×3)
thus, we can see that -10/15 is smaller than -9/15, and -2/3 is smaller than -3/5.
