Answer:
[tex]y = -\frac{3}{5}x -\frac{8}{5}[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (-1,-1)[/tex]
[tex](x_2,y_2) = (4,-4)[/tex]
Required
Determine the line equation
First, calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{-4 - (-1)}{4 - (-1)}[/tex]
[tex]m = \frac{-4 +1}{4 +1}[/tex]
[tex]m = \frac{-3}{5}[/tex]
[tex]m = -\frac{3}{5}[/tex]
The equation is then calculated using:
[tex]y - y_1 = m(x - x_1)[/tex]
This gives:
[tex]y - (-1) = -\frac{3}{5}(x - (-1))[/tex]
[tex]y + 1 = -\frac{3}{5}(x +1))[/tex]
Open bracket
[tex]y + 1 = -\frac{3}{5}x -\frac{3}{5}[/tex]
Make y the subject
[tex]y = -\frac{3}{5}x -\frac{3}{5}-1[/tex]
[tex]y = -\frac{3}{5}x +\frac{-3-5}{5}[/tex]
[tex]y = -\frac{3}{5}x +\frac{-8}{5}[/tex]
[tex]y = -\frac{3}{5}x -\frac{8}{5}[/tex]

Is (3,5) a solution to the system - x +y = 1 and 2x + 4y = 2?
Answer:
No, it is not.
Step-by-step explanation:
Answer: The answer is no.
Step-by-step explanation: Plug in the values of -x + y = 1. -3 + 5 [tex]\neq[/tex] 1, and even if the other equation works out, the system of equations would not be valid.
For which of the following equations is (-2,-3) not a solution?
A) y=x-1
B) -3x=4y-6
C) 2y-3x=0
D) 5x+2y=-16
Answer:
B) -3x=4y-6
Step-by-step explanation:
(-2,-3); x= -2 and y= -3
B) -3x=4y-6
-3x= 4(-3) - 6= -12-6= -18
x= -18/-3=6... wrong

Reduce the ratio to its lowest form. 72:8
Answer:
9:1
Step-by-step explanation:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 72 and 8 is 8
Divide both terms by the GCF, 8:
72 ÷ 8 = 9
8 ÷ 8 = 1
The ratio 72 : 8 can be reduced to lowest terms by dividing both terms by the GCF = 8 :
72 : 8 = 9 : 1
Therefore:
72 : 8 = 9 : 1

Answer:
[tex]y = 2 {(x - 3)}^{2} + 1[/tex]
Answer:
D) 2(x - 3)² + 1
Step-by-step explanation:
First off:
the equations are in y = a(x-h)²+k format.
So, that means that since the vtx is (3, 1), the answers could only be c or d
The difference between the two is one parabola is reflected (negative) and the other is facing up. Since (1, 9) is above the vtx, only D is the one that passes through (1, 9) because it is the only one facing upward to touch that point.
Shaun's earnings at $12 per hour were less than $150. Write an inequality

Step-by-step explanation:
A Data Scientist of a Fortune 500 banking firm is looking at the relationships between various age groups of adults and types of investments portfolios. He is looking at a Chi Square distribution in his statistical software. What is the probability that x is larger than 12 when df = 19?
Answer:
The probability that x is larger than 12 when df = 19 = 0.100
Step-by-step explanation:
We are supposed to find the probability value at x>12 at degree of freedom equals to 19.
P(x>12)
By looking at the chi square table we can see, at df = 19 and x>12, P(x>12) is equal to 0.100
because at df = 19, the least x values is 27.2036 for which (Px=27.2036) or (Px>12) = 0.100

If x = 0.75 and y = 0.6, find y when x = 5
Answer:
y = 4
Step-by-step explanation:
create a proportion, then cross-multiply
0.6 / 0.75 = y / 5
5(.6) = .75y
3 = .75y
y = 3/0.75
y = 4
