(0,1)
(1,-1)
plot points
y=-5x+4
(0,4)
(1,-1)
Step-by-step explanation:
Answer:
(1,-1)
Step-by-step explanation:
You would graph y=-2x+1 by starting the graph at (0,1) then placing another point at (-1, 3) and drawing a straight line through those points. You would graph y=-5x+4 by starting the graph at (0,4) then placing another point at (-1, 9) and drawing a straight line through those points. The answer would be where the two graphs intersect which is (1,-1).

make y the subject of the following :
Step-by-step explanation:
we first square both sides to eliminate the square root brackets..
(√(m(y+n)/y)²= p²
m(y+n)/y = p²
(my +mn)/y =p²
so we multiply both sides by y to eliminate the denominator,
(my+mn)/y*y =p²*y
my+mn = p²y
collecting like terms,we have:
mn= p²y-my
so we seperate the y on the right hand side from the rest to have
mn = y(p²-m)
so divided both sides by the value in the bracket on the right hand side we have..
mn/(p²-m)=y(p²-m)/(p²-m)
so we have,
y= mn/(p²-m)
Answer:
y = [tex]\frac{-mn}{m-p^2}[/tex]
Step-by-step explanation:
Given
[tex]\sqrt{\frac{m(y+n)}{y} }[/tex] = p ( square both sides )
[tex]\frac{m(y+n)}{y}[/tex] = p² ( multiply both sides by y )
m(y + n) = p²y ← distribute parenthesis on left side
my + mn = p²y ( subtract p²y from both sides )
my - p²y + mn = 0 ( subtract mn from both sides )
my - p²y = - mn ← factor out y from each term on the left side
y(m - p²) = - mn ← divide both sides by (m - p²)
y = [tex]\frac{-mn}{m-p^2}[/tex]

A coach travels to the beach which is 576 KM away in 6 hours. If he is only allowed to travel at a maximum speed of 90 kph, did the coach break the speed limit? What was his average speed?
Answer:
Yes
Step-by-step explanation:
576Km:6Hrs
576 divided by 6=96 km
6 divided by 6=1
96km:1hr
96 was the coaches speed limit
km=Kilometers
Hrs=Hours
96>90
yes , the coach break the speed limit and the average speed is 96 km ph
What is Speed?Speed is the time rate at which an object is moving along a path
Given,
A coach travels to the beach which is 576 KM away in 6 hours.
The maximum speed he can travel is speed of 90 kph
We need to check whether the coach breaks the speed limit or not.
Yes he has to break the speed limit because in 6 hours with 90kph he can travel only 540 km. He still needs to travel 36 km.
and the average speed he has to maintain is 576/6
96kmph
Hence, yes the coach break the speed limit and the average speed is 96 km ph

Answer:
The answer you are looking for is x = 3/10
Step-by-step explanation:
D( x )
x = 0
x = 0
x = 0
x in (-oo:0) U (0:+oo)
72/x = 3.6/0.015 // - 3.6/0.015
72/x-(3.6/0.015) = 0
72/x-240 = 0
72*x^-1 = 240 // : 72
x^-1 = 10/3
-1 < 0
1/(x^1) = 10/3 // * x^1
1 = 10/3*x^1 // : 10/3
3/10 = x^1
x = 3/10
x = 3/10
Answer:

What is the 50th term of the arithmetic sequence 7, 10, 13, ...?
show complete working format please
Answer:
154
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 10 - 7 = 3 , thus
a₅₀ = 7 + (49 × 3) = 7 + 147 = 154
Parallel lines e and f are cut by transversal b. What is the value of y?

Answer:
y = 130
Step-by-step explanation:
Those two exterior angles are equal (property of parallel lines)
y is thsupplement of 4x - 14
2x + 18 = 4x - 14 Add 14 to both sides
2x + 18 + 14 = 4x - 14 + 14 Combine like terms
2x + 32 = 4x Subtract 2x from both sides
2x-2x+32=42-2x Combine
32 = 2x Divide by 2
32/2 = x
16 = x

Select the correct answer in each of the following.
a) The value of a is
(-3,4)
A: negative
B: zero
C: positive
b) The value of c is
A: negative
B: zero
C: positive
c) The solutions of y=ax*2+ bx + c = 0 are
A: both negative
B: both positive
C: one negative and one positive
Answer:
A, A and A
Step-by-step explanation:
Given
y = ax² + bx + c
• If a > 0 then minimum vertex
• If a < 0 then maximum vertex
Here the vertex is a maximum, thus a < 0 , that is negative → A
The value of c is the y- intercept
The graph crosses the y- axis below the y- axis, thus c is negative → A
The solutions to ax² + bx + c = 0 are the values of x on the x- axis where the graph crosses the x- axis.
The graph crosses the x- axis to the left of the y- axis , thus
Both solutions are negative → A

The front and back covers of a textbook are each 0.3 cm thick. Between the covers are 200 sheets of paper, each 0.008 cm thick. How high is a stack of 10 books
Answer:
22 cm
Step-by-step explanation:
Start off by multiplying the number of pages by the thickness.
200*0.008=1.6
Add the thickness of the front and back cover.
1.6+0.6=2.2
Multiply by 10.
2.2*10=22 cm
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The height of the 10 stacks of books is 22cm.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that the front and back covers of a textbook are each 0.3 cm thick. Also, there are 200 sheets of paper between the cover and the thickness of each sheet is 200 sheets. Therefore, the thickness of the book is,
The thickness of a single book
= (Number of covers × Thickness of cover) + (Number of sheets × Thickness of sheets)
= (2 × 0.3cm) + (200 × 0.008cm)
= 2.2 cm
Now, the thickness of 10 books will be,
The thickness of 10 books = 10 × the Thickness of a single book
= 10 × 2.2 cm
= 22 cm
Hence, the height of the 10 stacks of books is 22cm.

11. A line that passes through (3, 1) and (0, -3)
Answer:
y=(4/3)x - 3
Step-by-step explanation:
Use equation (y-y1) =m (x-x1)
slope is m= (y1-y2)/(x1-x2)=1+3/3-0=4/3
use one of the points and this slope to complete the equation
(y-1)=(4/3)(x-3) distribute and add1 to both sides
y=(4/3)x-(3*4/3)+1
y=(4/3)x - 3
Answer:
y = [tex]\frac{4}{3}[/tex] x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, 1) and (x₂, y₂ ) = (0, - 3)
m = [tex]\frac{-3-1}{0-3}[/tex] = [tex]\frac{-4}{-3}[/tex] = [tex]\frac{4}{3}[/tex]
The line crosses the y- axis at (0, - 3) ⇒ c = - 3
y = [tex]\frac{4}{3}[/tex] x - 3 ← equation of line

Step-by-step explanation:
>>1 gram of carbs=4 cal
20 g of carbs times 4 calories per gram of carbs= 80 calories
>>1 gram of fat=9 calories
3 g of fat times 9 calories per gram of fat= 27 calories
>>1 gram of protein=4 calories
