Describe a linear equation in the form Ax + By = C for each condition.a. A = 0

b. B = 0

c. C = 0

Answers

Answer 1
Answer: a.
A=0
0x+By=C
0+By=C
By=C
this is just a horizontal line

b.
B=0
Ax+0y=C
Ax+0=C
Ax=c
this is just a vertical line


c.
C=0
Ax+By=0
this is a line that passes through the point (0,0)

What is the mean of Variable A? Express answer to one decimal place. Scatter plot on a first quadrant coordinate grid. The horizontal axis is labeled Variable A. The vertical axis is labeled Variable B. Points are plotted at (two, two), (two, eight), (four, three), (five, one), (six, three), (seven, five), (eight, six), (nine, two).

Answers

Variable A is x. Variable B is y. (x,y)

2 , 2, 4, 5, 6, 7, 8, 9

Mean is computed by adding all the numbers in the data set and dividing it by its count.

2 + 2 + 4 + 5 + 6 + 7 + 8 + 9 = 43

43 / 8 = 5.375 rounded to 5.4

Sam determines the zeros of the function f(x) to be 8 and 7. What could be Sam’s function?1.

f(x) = (x − 8)(x + 7)
2.

f(x) = (x − 8)(x − 7)
3.

f(x) = (x + 8)(x + 7)
4.

f(x) = (x + 8)(x − 7)

Answers

Answer:

2. f (x) = (x - 8)\cdot (x-7)

Step-by-step explanation:

Given that function is polynomial, each zero is contained in binomials of the form (x - a), where a is the value of the zero. The number of roots means the number of binomial and the grade of the polynomial. Then, the function has the following form:

f (x) = (x - 8)\cdot (x-7)

In cosequence, the right answer is 2.
Option 2: f(x) = (x-8)(x-7)

x-8 = 0 ⇒ x = 8

x-7 = 0 ⇒ x = 7

Suppose that a family wants to start a college fund for their child. If they can get a rate of 5.5% , compounded monthly, and want the fund to have a value of $35,450 after 20 years, how much should they deposit monthly? Assume an ordinary annuity and round to the nearest cent.

Answers

Answer:

They should deposit $81.38 monthly.

Step-by-step explanation:

We know that,

\text{FV of annuity}=P\left(((1+r)^n-1)/(r)\right )

where,

FV of annuity = $35,450

P = monthly payment,

r = rate of interest = 5.5% annually = (5.5)/(12)\%

n = number period = 20 years = 240 months

Putting all the values,

\Rightarrow 35450=P\left(((1+(0.055)/(12))^(240)-1)/((0.055)/(12))\right )

\Rightarrow P(35450)/(\left(((1+(0.055)/(12))^(240)-1)/((0.055)/(12))\right ))

\Rightarrow P=\$81.38

Therefore, they should deposit $81.38 monthly.
In 20 years a family will be able to earn 35 450 dollars. The interest that they earned is 5.5% compounded monthly. Now, let's find out how much will they need to save monthly to get this amount in 20 year:
=> 12 * 20 = 240 months
=> 35 450 / 240 months = 147.7 dollars per month is the money with interest
Let's subtract the interest
=> 147.7 * 0.055 = 8.1 dollars.
=> 147.7 - 8.1 = 139.6 dollars per month.

WILL GIVE BRAINLIEST 5 Adrian, Ben and Charlie share some sweets in the ratio 7:4:9
Charlie got 24 more sweets than Adrian.
Work out the total amount of sweets.​

Answers

Answer:

240 sweets total

Step-by-step explanation:

We know the ratio Adrian:Ben:Charlie=7:4:9. We can put one sweet as x:

  • 7x+4x+9x=20x
  • Charlie has 24 more sweets that Adrian– 9x-7x=2x=24
  • So– x=12
  • Now– 7(12)+4(12)+9(12)=20(12)=240

Check your work:

  • 84:48:108
  • 108-84=24
  • 84+48+108=240

Given 2 points on a graph, write the equation of the graph. Vertex (3,5). Point(5, -3)

Answers

we know that
for
y=a(x-h)^2+k
vertex is (h,k)
given vertex is (3,5)
y=a(x-3)^2+5
we are also given
(5,-3)
x=5 and y=-3 is a possible solution

-3=a(5-3)^2+5
-3=a(2)^2+5
minus 5 both sides
-8=a(4)
-8=4a
divide by 4 both sides
-2=a


the equation is
y=-2(x-3)^2+5
