y = [tex]\frac{5x-1}{3}[/tex]
make x the subject
3y = 5x - 1
3y + 1 = 5x
[tex]\frac{3y + 1}{5}[/tex] = x
now switch x with y

Answers
Step-by-step explanation:
Slope formula:
[tex] \frac{y2}{x2} - \frac{y1}{x1} = m[/tex]
m = slope
Substitute the points into the formula format:
[tex] \frac{ - 6}{1} - \frac{30}{ - 5} = m[/tex]
Solve:
[tex] \frac{ - 36}{6} = m[/tex]

1) A car moves with a speed of 40 km/h for 15 mins and then with a speed of 60 km/h for next 15 mins . The total distance covered by the car is : _________
(a) 100km. (b) 25km
(c) 15km. (d) 10km
• Don't spam
• Need Genuine Answer with Explanation .
Answers
Answer:
25 km
Explanation:
Distance = speed * time
We have change time which are given in minutes to hour. As the speed is mentioned in kilometre per hour.
For part A:
[tex]\rightarrow Distance = speed * time[/tex]
[tex]\hookrightarrow Distance = 40 * \frac{15}{60}[/tex]
[tex]\hookrightarrow Distance = 10[/tex] km
For part B:
[tex]\rightarrow Distance = speed * time[/tex]
[tex]\hookrightarrow Distance =60 * \frac{15}{60}[/tex]
[tex]\hookrightarrow Distance = 15[/tex] km
Total distance covered:
part A + part B
10 km + 15 km
25 km
25 km
Solution :-Speed of the car in first 15 mins ,
The car is moving in the speed of 40 km/h for 15 mins.
Distance covered = speed × Time taken Distance covered = 240 × 15/60 = 10 kmSpeed of car in next 15 mins ,
again ,
distance covered = 60 × 15/60 = 15kmnow , total distance covered = ( 10 + 15 ) km = 25 km

6x = 26+4
6x= 30
x= 5
6x = 26 + 4
Add 26 and 4 to get 30:
6x = 30
Divide both sides by 6:
x = ³⁰/₆
Divide 30 by 6 to get 5:
x = 5

[] First, we will set up an equation for Ross.
-> We will use slope-intercept form (see attached)
-> The slope:
[tex]\frac{y_{2} -y_{1}}{x_{2} -x_{1} }[/tex] = [tex]\frac{81-40.5}{6-3}[/tex]=[tex]\frac{40.5}{3}[/tex]=13.5
-> The y-intercept:
y = 13.5x + b
(81) = 13.5(6) + b
81 = 81 + b
0 = b
-> Final equation:
y = 13.5x
-> For 8 hours, we will plug in 8 as the x.
y= 13.5(8)
y = $108
[] Joey earns 3 dollars more,
y = (13.5 + 3)x
-> Now we will plug 8 into the equation as x,
y = $132

Answer:
A = 6
B = 10
Step-by-step explanation:
[] Let's look at the system again:
[tex]\left \{ {{Ax+By=38} \atop {2Ax-By=16}} \right.[/tex]
[] They give us a set of x and y values, (3, 2) so we can plug them into the system.
[tex]\left \{ {{A(3)+B(2)=38} \atop {2A(3)-B(2)=16}} \right.[/tex]
[] Now, we can solve this with a graphing calculator. Let A be x and B be y for the sake of graphing.
A = x
B = y
[tex]\left \{ {{x(3)+y(2)=38} \atop {2x(3)-y(2)=16}} \right.[/tex]
-> See attached
[] We can see the lines intersect at (6, 10) so the answer is A = 6 and B = 10.

In Exercises 25–28, the red figure is the image of the
blue figure after a dilation with center C. Find the
scale factor of the dilation. Then find the value of
the variable.
Answers
Dilation involves changing the size of a shape
The scale factor is 2, and the value of the variable is 6
How to determine the scale factorFrom the figure, the scale factor is the quotient of the red figure and the blue figure.
So, we have:
[tex]k = \frac{28}{14}[/tex]
Divide
[tex]k = 2[/tex]
The value of the variable (n) is then calculated as:
[tex]n * k = 12[/tex]
This gives
[tex]n * 2 = 12[/tex]
Divide both sides by 2
[tex]n = 6[/tex]
Hence, the scale factor is 2, and the value of the variable is 6
