Here we need to plot x and y co-ordinates from the given table.
What are x and y co-ordinates and intercepts ?This is 2D co-ordinate geometry here we have an x axis and a y axis we use co-ordinate geometry to plot lines and curves according to the gives question.when the question consist of linear equations they form straight lines and when questions consists of quadratic and higher degree polynomials they form curves.
a. Here the the days are represented by x and remaing balance are represented by y.
So, when x = 0, y = 20 is co-ordinate form we can represent this as (0,20)
similarly the other co-ordinate points are (1,16), (2,12), (3,8), (4,4), (5,0).
b. x- and y- intercepts represnts the value of one variable corresponding to the other variable.

2a+4=3 what is the value of a???????
Hey there!
2a + 4 = 3
ADD 4 to BOTH SIDES
2a + 4 - 4 = 3 - 4
CANCEL out: 4 - 4 because that gives you 1
KEEP: 3 - 4 because it helps solve for the a-value
2a = 3 - 4
3 - 4 = -1
2a = -1
DIVIDE 2 to BOTH SIDES
2a/2 = -1/2
CANCEL out: 2/2 because it gives you 1
KEEP: -1/2 because it gives you the value of the a-value
a = -1/2
SIMPLIFY IT!
Therefore, your answer is: a = -1/2
Good luck on your assignment and enjoy your day!

Find the x and y intercepts
Answer:
x:(-1,0),(5,0)
y:(0,-2)
Answer:
see explanation
Step-by-step explanation:
The x- intercepts are where the graph crosses the x- axis
The graph crosses the x- axis at x = - 1 and x = 5 ← x- intercepts
The y- intercept is where the graph crosses the y- axis
The graph crosses the y- axis at - 2 ← y- intercept

If f(x)= x² + 3x –10, then over which of the following intervals is f(x) <0?
Answer:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
Interval Notation: (−∞,∞)
Set-Builder Notation: {x|x∈R}

1) Given A = {1, 2, 3, 4, 5 }; B = {2,4,6,83 2,4,6,8} Find A∩B, A-B
2) Is it true to say that sin ( A+B) = -sinA + sinB
3) prove that ( tan theta - sin theta ) / ( tan theta + sin theta ) = ( sec theta - 1 ) / ( sec theta + 1 )
Answer:
A∩B = 2,4
A-B = 1,3,5
sin (A+B) = sin(A)cos(B)+cos(A)sin(B)
Step-by-step explanation:
A intersects U means the numbers that are coming to both A and U

4(x6+5)=2x+10 I'm not sure what the answer is can somebody help???
Answer:
[tex]4(6x + 5) = 2x + 10 \\ 4 \times 6x + 4 \times 5 = 2x + 10 \\ 24x + 20 = 2x + 10 \\ 24x - 2x = 10 - 20 \\ 22x = - 10 \\ x = \frac{ - 10}{22} = \frac{ - 5}{11} \\ thank \: you[/tex]
Answer:
-5 / 11 or -0.455
Step-by-step explanation:
this is a very simple question that does not need much complexity about it
we have
4( 6x + 5 ) = 2x + 10
first of all, we open the bracket;
24x + 20 = 2x + 10
now, we have to collect like terms;
24x - 2x = 10 - 20
22x = -10
divide through by 22 to give us!
22x / 22 = -10 / 22
x = -5 / 11
therefore,
x = - 5 / 11
hope that helps
thank you
Solve the system by substitution.
−5x+2y=14
y=3x+2
let −5x+2y=14 be [1]
& y=3x+2 be [2]
Finding the value of x
By substituting y in [2] for y in [1]
⇒ −5x + 2(3x+2) = 14 [expand the bracket]
⇒ -5x + 6x + 4 = 14 [subract 4 from both sides and simplify]
⇒ x = 10
Finding the value of y
Since x =10, we can substitute value of x into [2]
⇒ y = 3(10) + 2
⇒ y = 32

Part A Write an expression to find size of the largest jellyfish. Represent the expression in meters as a product of two numbers in scientific notation.
Answer:
The expression for the size of the largest jellyfish 1 × 108 • 2 × 10-8 meters.
Step-by-step explanation:
A jellyfish can be up to 1 × 108 times bigger than femtoplankton. Find the size of the largest jellyfish by multiplying the size of a femtoplankton by 1 × 108 times.
The size of a femtoplankton is 2 × 10-8 meter. That means the expression for the size of the largest jellyfish 1 × 108 • 2 × 10-8 meters.

The sides of a rectangle are in the ratio of 5:6. If its longer side is 7.2 in., find the shorter side, the perimeter, and the area of this rectangle. PLSSS HELP
Answer:
43.2
26.4
6
Step-by-step explanation:
so first if we know that the loger side's ratio is 6 we divided by 7.2
7.2 divided by 6 which is 1.2
so we mulitply the 5 by 1.2
so the shorter side is 6
6 x 7.2 = 43.2 is the area
14.4 + 12 = 26.4 is the perimeter
An art teacher has 47 1/3 pounds of clay.he wants to give each student in his class 2 1/2 pounds of clay. The teacher estimates that he has enough clay for 9 students. Is this the best estimates explain
Answer:
47 1/3 = 142 / 3 total clay
2 1/2 = 5 / 2 clay required for each student
If we divide total clay by clay per student
(142 / 3) / (5 / 2) = 284 / 15 = 18.9
So he should have enough clay for 18 students
