Answer:
y= 8x +7
Step-by-step explanation:
slope-intercept form:
y= mx +c, where m is the gradient (or slope) and c is the y-intercept.
Since it is a linear function, the gradient of any 2 points would be equal.
[tex]gradient = \frac{y1 - y2}{x1 - x2} [/tex]
Thus, gradient of the line
[tex] = \frac{39 - 23}{4 - 2} \\ = \frac{16}{2} \\ = 8[/tex]
Subst. m=8 into the equation:
y= 8x +c
To find the value of c, substitute a pair of coordinates.
When x=0, y= 7,
7= 8(0) +c
c= 7
Thus, the equation of the linear function is y= 8x +7.
The equation Y+3=5(x-2)
goes through with point?
(2,-3)
(3,-2)
(-2,3)
(-3,2)
Answer:
(2, -3)
Step-by-step explanation:
Well the equation is y - y1 = m ( x - x1)
-3 = y1
2 = x1
(2, -3)
Answer:
(2,-3)
Step-by-step explanation:
The given equation is in point-slope form. That is,
[tex]y-y1=m(x-x1)[/tex]
[tex]x1[/tex] and [tex]y1[/tex] is a point, while [tex]m[/tex] is the slope.
So, [tex]y1=-3[/tex] and [tex]x1=2[/tex].
The point that this equation passes through is (2,-3).

Container A and container B have leaks. Container A has 800 ml of water, and is
leaking 6 ml per minute. Container B has 1000 ml, and is leaking 10 ml per minute.
How many minutes will it take for the two containers to have the same amount of
water?
**Write an equation to represent the situation (first blank). Use the variable m, for
minutes.
**Then solve for m (second blank).
**Finally, use your solution to determine the water level at that time (third blank).
The equation
can represent this situation. It will take
minutes for the two containers to have the same amount of water. At this time,
both containers will have ml left.
Answer:
a) 50 minutes
b) The water level at 50 minutes for Container A and B would be 500ml
Step-by-step explanation:
a) Let number of minutes at which both containers leak be represented by m.
Container A has 800 ml of water, and is leaking 6 ml per minute.
800ml - 6ml × m
800 - 6m
Container B has 1000 ml, and is leaking 10 ml per minute.
1000ml - 10ml × m
1000 - 10m
How many minutes will it take for the two containers to have the same amount of water?
Container A = Container B
800 - 6m = 1000 - 10m
Collect like terms
-6m + 10m = 1000 - 800
4m = 200
m = 200/4
m = 50 minutes
It will take 50 minutes for the two containers to have the same amount of water.
b) Finally, use your solution to determine the water level at that time.
Since m = 50 minutes
Container A = Container B
800 - 6m = 1000 - 10m
800 - 6 × 50 = 1000 - 10 × 50
800 - 300 = 1000 - 500
500 ml = 500 ml
Therefore, the water level at 50 minutes is 500 ml

A rectangular meadow has an area of 28 square
meter and perimeter 22 m, find the length and breadth.
Answer:
perimeter =22m
area=28square meter
perimeter of rectangle=4l
22m=4l
22÷4=l
5.5=l
l=5.5m
area of rectangle =l×b
28=5.5×b
28÷5.5=b
5.09=b
b=5.09m

Answer:
1. Right: pointing downwards
Left: pointing upwards
2. Right: pointing upwards
Left: pointing upwards
3. Right: pointing downwards
Left: pointing upwards
4a. True
4b. True
Step-by-step explanation:
When the leading coefficient is negative the equation will either open downwards or the y-values will decrease as the x-values increase. The opposite is true for when the leading coefficient is positive. When the degree is odd one end will point downwards while the other points upwards. When the degree is even, both ends point in the same direction.

Johny and Rahul divided the benefit of the business in the ratio 7:9. If
Rahul got 4878 rupees as benefit did Johny get?
Answer:
Step-by-step explanation:
7:9 = x:4878
4878/9 times 7
3794 would be your answer
Answer:
3,794 rupees
Step-by-step explanation:
Johny got 7 parts of the benefit while Rahul got 9. This can be represented as a fraction: 7/9
To solve this problem, we can use cross multiplication, where x represents the amount of rupees Johny got:
[tex]\frac{7}{9}[/tex] = [tex]\frac{x}{4878}[/tex]
Multiply 7 by 4,878: 34,146
Multiply 9 by x: 9x
Now the equation looks like this:
9x = 34,146
Divide both sides of the equation by 9 to isolate the x:
9x/9 = 34,146/9
x = 3,794
Johny got 3,794 rupees.

Here are 36 carpenters on a construction crew. On a certain day, 29 carpenters were present. Which proportion can be used to determine the percent of carpenters that were present?
Answer:
80.6%
Step-by-step explanation:
Given that :
Total construction crew = 36
Number present in a certain day = 29
Percentage present on that day :
(Number present / total number) * 100%
(29 / 36) * 100%
0.8055555 * 100%
80.555%
= 80.6%
