A teacher asked his students to solve the equation w-15=22. One student incorrectly said that the solution is 7. What is the cor

jonny [76]

Answer:

$w= 37$

Step-by-step explanation:

The student used the wrong property of equality.

When you undo a number to get a letter by itself, you should do the opposite operation of the number said. The student subtracted 15 from 22 instead of adding 15 to 22.

Use the addition property of equality to isolate w.

$w(-15+15)=22+15\\w=37$

suppose you deposit $2,475 in a savings account that earns 6.25% simple interest per year. How much simple interest would be ear

Nikolay [14]

$116.02 interest will be earned in 9 months

Step-by-step explanation:

The formula for simple interest is given by:

$I = Prt$

Here

P is the initial amount

r is the interest

t is the time measured in years

Given

P = $2475

r = 6.25% = $\frac{6.25}{100} = 0.0625$

t = 9 months

Converting time into year by dividing by 12

$t = \frac{9}{12}\ years = 0.75\ year$

Putting the values in the formula

$I = 2475 * 0.0625 * 0.75\\I = 116.0156$

Rounding off to nearest hundredth

I = $116.02

Hence,

$116.02 interest will be earned in 9 months

X^2 + 8x + 6

Maurinko [17]

Ax^2+bx+c=0
a=leading term

ok so if the leading term is positive then opens up and has a min
if leading term is negative then opens down and has a max

leading term is positive
1x^2+8x
has a max

to complete the square, move c aside take 1/2 of b and square it
b=8
8/2=4
4^2=16
now add that to both sides
x^2+8x+16+6=0+16
factor perfect square
(x+4)^2+6=16
subtract 6
(x+4)^2=10
subtract 10
(x+4)^2-10=0
vertex aka min or max is (h,k) when ou have
y=a(x-h)+k
h=-4
k=-10
