We are given equation y = -3x^2.

We need to check the given table.

We have x=-2,-1,0,1,2 in the given table.

Plugging x=-2,-1,0,1,2 in the given equation

For x=-2

y = -3 (-2)^2 = -3(4) = -12

For x =-1

y = -3 (-1)^2 = -3(1) = -3

For x =-0

y = -3 (0)^2 = -3(0) = 0

For x =1

y = -3 (1)^2 = -3(1) = -3

For x =2

y = -3 (2)^2 = -3(4) = -12.

Therefore, correct table is

<h3>   x       y      (x,y)</h3><h3>_____________</h3><h3>  -2   -12       (-2,-12)</h3><h3>  -1    -3        (-1,-3)</h3><h3>   0    0        (0,0)</h3><h3>   1     -3        (1,-3)</h3><h3>   2    -12       (2,-12).</h3><h3>________________</h3>

If g(x) = 4x + 1 and g(x) = -11, find x.
podryga [215]

Answer:

x = - 3

Step-by-step explanation:

g(x) = 4x + 1...... (1)

g(x) = -11.... (2)

From equations (1) & (2)

-11 = 4x + 1

-11 - 1 = 4x

-12 = 4x

-12/4 = x

-3 = x

x = - 3

You invested $ 7000 between two accounts paying 3 % and 5 % annual? interest, respectively. If the total interest earned for the
natita [175]

Answer:

In the first account was invested \$3,000  at 3%

In the second account was invested \$4,000  at 5%

Step-by-step explanation:

we know that

The simple interest formula is equal to

I=P(rt)

where

I is the Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

First account

t=1 years\\ P=\$x\\ r=0.03

substitute in the formula above

I=x(0.03*1)

I=0.03x

Second account

t=1 years\\ P=\$(7,000-x)\\ r=0.05

substitute in the formula above

I=(7,000-x)(0.05*1)

I=350-0.05x

Remember that

The interest is equal to \$290

so

Adds the interest of both accounts

0.03x+350-0.05x=\$290

0.05x-0.03x=350-290

0.02x=60

x=\$3,000

therefore

In the first account was invested \$3,000  at 3%

In the second account was invested \$7,000-\$3,000=\$4,000  at 5%
