Answer:

y=0.3x - 7.6

Step-by-step explanation:

line: y=ax+b

a= Δy ÷ Δx

a= (-9 + 7) ÷ (-5 - 2)

a= -2 ÷ -7 = approximately 0.3

y=0.3x + b

Now you can fill in one of the points to find b (or both to make sure you got the answer right).

0.3 × 2 + b = -7

0.6 + b = -7

b = -7 - 0.6 = approximately -7.6

So: an equation of the line that passes through this pair of points is y=0.3x - 7.6

On a test, i would write as many decimals as possible if not said not to, to get the most exact answer. Also remember to keep calculating with the number on your calculator and not to round them off for the most exact answer.

Answer:

x = -5

Step-by-step explanation:

If one draws a perfect verticle line at x = -5, one will have exactly 1/2 the parabola on each side. Then is one where to fold the parabola on that line, then there would be no overhang. Hence x = -5 is the axis of symmetry.

Answer:

∠EFA

Step-by-step explanation:

The diagram shows several rays starting at point F. There are 2 sets of rays that are opposite to each other ie their angles add up to 180°

These are
FD and FA
FB and FE

You can ignore the other two rays since they do not have any opposite rays and therefore do not figure in a linear relationship

Ignoring FG and FC we get the equivalent of two lines crossing each other at point F

We can eliminate any angles that contain C and G
So we can eliminate ∠BFC, ∠CFG and ∠GFD

Which leaves the last choice as the only option

So answer is ∠EFA

∠EFA is linearly paired with ∠BFD since they lie on the same straight line and the measure of sum of their angles is 180°

∠EFA also is vertically paired with ∠BFD since these angles are opposite each other

The set of non negative powers of 10 is given as

  (x | x = 10ⁿ , n = 0,1,2,3....)

Powers of 10 is any integer powers of the number 10. In simple words 10 multiplied by itself several times.

We need to define a set of nonnegative powers of 10 using the given set builder notation .

Powers of 10 is expressed as = 10ⁿ where n = 0,1,2,....

Thus in set builder form we can write

(x | x = 10ⁿ , n = 0,1,2,3....) which states that x is such that (which is denoted as '|' ) x is equal to 10ⁿ where n is equal to 0,1,2,....

Hence the set of non negative powers of 10 is given as

  (x | x = 10ⁿ , n = 0,1,2,3....)

The required answers for the given questions is question are 1) x = -4,  2)  x = 6 - √15,   3) x = 3 + 3√3,   4) x = -3,  and  5)x = -9 - √21  / 5

The quadratic Equation formula is x = -b ± √(b² - 4ac) / 2a

1. x² + 7x + 12 = 0

By using the above formula

Here a = 1, b = 7, c = 12

x = -7 ± √(7² - 4*1*12) / 2*1

x = -7 ± √(49 - 48) / 2

x = -7 ± √1 / 2

x = -7 ±1 /2

x = -7+1 /2           x = -7 - 1 / 2

x = - 6 / 2            x = -8 / 2

x = -3                   x = -4

2) x²-12x+21=0

By using the above formula

Here a = 1,  b = -12, c = 21

x = -(-12) ± √((-12)² - 4*1*21) / 2*1

x = 12 ± √(144 - 84) / 2

x = 12 ± √60 / 2

x = 12 ±2√15  /2

x = 12 + 2√15 /2           x = 12 - 2√15  / 2

x = 6 + √15          x = 6 - √15

3. 18+6y-y²=0

By using the above formula

Here a = -1, b = 6, c = 18

x = -6 ± √((6² - 4*(-1)*18) / 2*(-1)

x = -6 ± √(36 + 72) / -2

x = -6 ± √108 / -2

x = -6 ± 6√3 / -2

x = -6+6√3 /-2           x = -6 - 6√3 / -2

x = 3-3√3            x = 3 + 3√3

4. 3x²+14×+15=0

By using the above formula

Here a = 3, b = 14, c = 15

x = -14 ± √((14² - 4*(3)*15) / 2*(3)

x = -14 ± √(196 - 180) / 6

x = -14 ± √16 / 6

x = -14 ± 4 / 6

x = -14 + 4 /6           x = -14 - 4  / 6

x = -10 / 6                x = -18 / 6

x = -5/3                   x = -3

5.5x²-18x+12=0 ​

By using the above formula

Here a = 5, b = -18, c = 12

x = -18 ± √((18² - 4*(5)*12) / 2*(5)

x = -18 ± √(324 - 240) / 10

x = -18 ± √84 / 10

x = -18 ± 2√21 / 10

x = -18 + 2√21 /10           x = -18 - 2√21  / 10

x = -9 + √21 / 5                x = -9 - √21  / 5

Hence, the values of the given question are 1) x = -4,  2)  x = 6 - √15,   3) x = 3 + 3√3,   4) x = -3,  and  5)x = -9 - √21  / 5

Answer:

The additional money that Ed Moura should invest in certificates of deposit paying 4% so that the average return on the two investments is 5% is 219,000.

Step-by-step explanation:

It is given that Ed Moura has $73,000 invested in stocks earning an average return of 8%, and that he should put the remaining funds in certificates of deposit paying an average return of 4%, the average return on the two investments is 5%, than;

=> 0.08 (73,000) + 0.04b = 0.05 (b + 73,000)

=> 5840 + 0.04b = 0.05b + 3650

=> 0.01b = 2190

=> b = 219,000

=> $219,000

Therefore, the additional money that Ed Moura should invest in certificates of deposit paying 4% so that the average return on the two investments is 5% is $219,000.
