Which point-slope form equation represents a line that passes through (3,-2) with a slope of -4/5
son4ous [18]

Answer:

y + 2 = - \frac{4}{5}(x - 3)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = - \frac{4}{5} and (a, b) = (3, - 2), hence

y - (- 2) = - \frac{4}{5}(x - 3), that is

y + 2 = - \frac{4}{5}(x - 3)

Which of the binomials below is a factor of this trinomial? ---- PLS EXPLAIN FOR ME?
Dennis_Churaev [7]
To factor this notable trinomial, you have to find two numbers that summes give -5 and multiplied give 6*(-25) = -150

Then let's call n1 and n2 the two numbers and a the number before x^2 (6)

ax^2+sx+fn = (ax + n1)(x + n2/a)

Numbers are -15 and +10

-15+10 = -5
-15*10 = -150

So

(6x-15)(x + 10/6)

Or write it as a sum

6x^2 + 10x - 15x - 25

And factor

6x^2 + 10x = 2x(3x+5)

-15x-25 = -5(3x+5)

(2x-5)(3x+5)

Answer:

143 calories

Step-by-step explanation:

We can use a ratio to solve

110 calories      x calories

----------------- = ---------------

28.4 grams         36.92 grams

Using cross products

110* 36.92 = 28.4 * x

Divide each side by 28.4

110*36.92 / 28.4 = x

143 calories = x

I have no idea how to do this please help
never [62]

Remember that

An explicit formula directly calculates the term in the sequence that you want

in this problem we have

5,8,11,14,...

so

a1=5

a2=8

a3=11

a4=14

a2-a1=8-5=3

a3-a2=11-8=3

a4-a3=14-11=3

the common difference d=3

An explicit formula is equal to

a_n=a_1+d(n-1)

we have

a1=5

d=3

substitute

\begin{gathered} a_n=5+3(n-1) \\ a_n=5+3n-3 \\ a_n=2+3n \end{gathered}

the answer is

<h2>an=2+3n</h2>

Mr. May invested $21,000, part at 8% and the rest at 6%. If the annual income for from both investments were equal find the amou
Vikki [24]

Answer: the amount of money invested at the rate of 8% is $9000

the amount of money invested at the rate of 6%. Is $12000

Step-by-step explanation:

Let x represent the amount of money invested at the rate of 8%.

Let y represent the amount of money invested at the rate of 6%.

Mr. May invested $21,000, part at 8% and the rest at 6%. This means that

x + y = 21000

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time

Considering the investment at the rate of 8%,

P = x

R = 8

T = 1

I = (x × 8 × 1)/100 = 0.08x

Considering the investment at the rate of 6%,

P = y

R = 8

T = 1

I = (y × 8 × 1)/100 = 0.06y

If the annual income from both investments were equal, it means that

0.08x =0.06y - - - - - -1

Substituting x = 21000 - y into equation 1, it becomes

0.08(21000 - y)=0.06y

1680 - 0.08y = 0.06y

0.06y + 0.08y = 1680

0.14y = 1680

y = 1680/0.14 = 12000

Substituting y = 12000 into

x = 21000 - y

x = 21000 - 12000

x = 9000
