Answer:
y=2x-11
Step-by-step explanation:
arralel lines have same gradient
since gradient of the known line is 2( the coefficient of x), it therefore follows that the gradient of the second line we want to find is also 2
So we know the gradient of the second line is 2, and we have one known point (7,3). We can therefore apply the formula for finding gradient to come up with the line
[tex]2=\frac{y-3}{x-7} \\\\y-3=2(x-7)\\\\y-3=2x-14\\\\y=2x-14+3\\\\y=2x-11[/tex]

the transformation from f(x) to g(x) is (c) the graph of g(x) is horizontal compression of the graph f(x) by a factor of 1/3 and a reflection across the x-axis.
How to compare both functions?The functions are given as:
f(x) =x^3
g(x) = -(3x)^3
The minus sign in g(x) = -(3x)^3 implies that the function f(x) is reflected across the x-axis
The 3 in g(x) = -(3x)^3 implies that the function f(x) is stretched horizontally by 1/3

,
tan < 0
The exact values of the remaining trigonometric functions are sin(x) = -7/25 and tan(x)= -7/24
How to solve the trigonometric functions?The function is given as:
cos(x) = 24/25, tan(x) < 0
The sine function is calculated using:
sin^2(x) + cos^2(x) = 1
So, we have:
sin^2(x) + (24/25)^2 = 1
Collect like terms
sin^2(x) = -(24/25)^2 + 1
Evaluate the squares
sin^2(x) = -576/625 + 1
Take the LCM
sin^2(x) = (625-576)/625
Evaluate
sin^2(x) = 49/625
Take the square roots
sin(x) = -7/25 --- sin(x) is negative because tan(x) < 0
The tangent function is calculated using:
tan(x) = sin(x)/cos(x)
This gives
tan(x) = (-7/25) / (24/25)
Evaluate
tan(x)= -7/24
Hence, the exact values of the remaining trigonometric functions are sin(x) = -7/25 and tan(x)= -7/24

Three friends start a business and decide to split the profits equally. Susan invests $6,000, John invests $4,000, and Pria invests $7,000. If the profits are $12,000, how much of the profits would Pria receive if the profits were divided proportional to how much each friend invested
Susan investment = $6000
John investement = $4000
Pria investment = $12000
investment proportion of Susan, John and Pria = 6:4:12= 3:2:6
Hence, Pria share in profit = (6/11)*$12000
= $ 6,545.454
Answer:
Pria receives $4941.18 of the profits.
Step-by-step explanation:
• Susan invested $6,000,
• John invested $4000,
• Pria invested $7000.
The ratio of their investments Susan : John : Pria is 6000 : 4000 : 7000 ,
⇒ 6 : 4 : 7
This means that Pria should receive 7/17 th of the total profits.
∴ Pria receives = [tex]\frac{7}{17}[/tex] × $12,000

Micaela and Chelsea each improved their yards by planting rose bushes and ivy. They bought their supplies
from the same store. Micaela spent $58 on 5 rose bushes, r, and 3 pots of ivy, i. Chelsea spent $100 on 5
rose bushes and 10 pots of ivy. Write equations to represent the scenario. Then, find the cost of one rose
bush and the cost of one pot of ivy.
Answer: A rose bush, r, cost $8; one pot of ivy, i, cost $6;
Step-by-step explanation:
[tex]\left \{ {{5r + 3i =58} \atop {5r+10i=100}} \right.[/tex]
We combine them by minus, we get:
5r + 3i = 58
- 5r + 10i = 100
- 7i = - 42
i = 6
We plug in i = 6 to the first equation, we get:
5r + 3(6) = 58
5r + 18 = 58
5r = 40
r = 8
The cost of one rose bush is $8 and the cost of one pot of ivy is $6.
How to calculate the equationHere are the equations to represent the scenario:
Micaela: 5r + 3i = 58
Chelsea: 5r + 10i = 100
Let's solve the system of equations to find the cost of one rose bush (r) and one pot of ivy (i).
Subtracting the first equation from the second equation, we get:
7i = 42
Dividing both sides by 7 we get:
i = 6
The rose bushes will be:
5r + 3i = 58
5r + 18 = 58
5r = 58 - 18
5r = 40.
r = 8
This means that the cost of one rose bush is $8 and the cost of one pot of ivy is $6.

A product is made up of three parts A B and C .The manufacturing in process is such that the probability of A being defective is 0.2..The probability of B being defective is 0.1 and probability of C being defective is 0.3.Find the probability that the assembled will have
a) No defective
b) at least two defective parts.
The probability that there'll be no defective will be 0.504.
How to calculate the probability?Probability of A being defective = 0.2.
Probability of B being defective = 0.1
Probability of C being defective = 0.3.
The probability that there will be no defective will be:
= (1 - 0.2) × (1 - 0.1) × (1 - 0.3)
= 0.8 × 0.9 × 0.7
= 0.504
The probability that there'll be no defect is 0.504.
The probability that there'll be at least two defective part will be:
= (0.2 × 0.1) + (0.2 × 0.3) + (0.1 × 0.3)
