Answer:

v=-5 and v=3

Step-by-step explanation:

We are given that

v^2-15=-2v

We have to find  two solutions of quadratic equation.

v^2+2v-15=0

Using addition property of equality

v^2+5v-3v-15=0   (By using factorization method)

v(v+5)-3(v+5)=0

(v+5)(v-3)=0

Substitute each factor equal to 0

v+5=0 and v-3=0

v=-5 and v=3

Hence, two solutions of quadratic equation are

v=-5 and v=3

Answer:

82

Step-by-step explanation:

We are given that a graph which shows the number of beads used for varying cord lengths.

The graph

y=2.52x+1.61

We have to find the number of beads that she can used for cord length 32 in.

Substitute the value x=32

Then, we get

y=2.52(32)+1.61=82.25

After round to unit place then, we get

y=82

Hence, the best estimate she can used  for number of beads =82

What is the equivalent amount in year ten of an expenditure of $5,000 in year one, $6,000 in year two, and amounts increasing by
Archy [21]

Answer:

The correct answer is the equivalent amount is $139,059.41

Step-by-step explanation:

According to the scenario, the computation of the equivalent amount in year ten is shown below;

= $5,000 × (P/A, 10%,10) + $1,000 × (P/G, 10%,10)

= $5,000 × 6.1466 + $1,000 × 22.8913

= $30,723 + $22,891.30

= $53,614.30

Now the equivalent amount is

= $53,614.30 × (F/P, 10%,10)

= $53,614.30 × 2.5937

= $139,059.41

Hence, the equivalent amount is $139,059.41

10w + 4w = -84 solve by combining like terms show all steps leading to awnser plz
Ira Lisetskai [31]
10w + 4w = - 84
14w = - 84
w = - 84 : 14
w = - 6  (  answer )
-----------------------------------
10 * (- 6) + 4 * (- 6) = - 84
            - 60 + (- 24) = - 84
                         - 84 = - 84

How do you write the following linear equations in standard form ?
ANTONII [103]
Hi<span>, Victoriasoto93p63zva!

To rewrite these equations in standard form you need to understand that standard form looks something like this Ax+By=C, now obviously there will be variations like </span>Ax-By=C or -Ax+By=C, etc..., but for these expressions, they would look like this:
<span>1. -8y + 0x = 37
2. 14x </span>+ 4y<span> = -18
3. x + </span>\frac{3}{5} y = \frac{4}{5} <span>
4. 13x + 0y = -25
