The straight line joining the points A(3,-5) and B(6,k) has a gradient of 4.
Gradient is the slope
So the slope of the line joining the points A(3,-5) and B(6,k) is 4
Slope of line joining two points =
A(3,-5) and B(6,k) are (x1,y1) and (x2,y2)
slope =
slope =
We know slope =4
Cross multiply and solve for k
k + 5 = 12
k = 7
The value of k = 7
Answer:
you need to isolate t or time
you need to know distance between sun and earth and velocity of them in order to calculate how long it takes for light to travel from the Sun to Earth
Step-by-step explanation:
to find time you multiply t to both sides then you cancel t from where velocity is and you get velocity by itself
now you mulipy d to both side to get v over d and time by itself
Answer:
first one

Answer:
Step-by-step explanation:
↔Start of with your 'solution section' to make sure you have the right things↔
↔Solution 1 ➡ 4(x) + 9(y) = 16
↔Solution 2 ➡ 6(x) - 9(y) = 8
-----------------------------------------------------------------
▪Looking for the value of the 'x'-intercept ⬇▪
◾4 (3) (y) / 2 + 4/ 3 + 9(y) = 16
◾15(y) = 32 / 3
◾ 45(y) = 32
▪x-intercept: 32
-----------------------------------------------------------------
◾Looking for value of the 'y'-intercept ◾
◾45(y) = 32
◾y-intercept : 45
◾x = 3(y)/2+4/3 which is translated to this, am i correct? ➡ (y) = 32/45
-----------------------------------------------------------------
↪ Now, we have finally found both of their intercept ⬇
↪x-intercept: 12
↪y-intercept: 5
↪Or you can even say the intercepts in other words. Here's what I am talking about if in case you don't know what I am saying
↪x-intercept: 32✅
↪y-intercept✅
Let's solve your equation step-by-step.
5=(−4)(8)+b
Step 1: Simplify both sides of the equation.
5=(−4)(8)+b
5=−32+b
5=b−32
Step 2: Flip the equation.
b−32=5
Step 3: Add 32 to both sides.
b−32+32=5+32
b=37
