Answer:

-7

Step-by-step explanation:

number - n

Twice a number - 2n

Seven times the number - 7n

2n = 7n +35

7n-2n = -35

5n = -35

n = - 7

Check:

2(-7) = 7(-7) +35

-14 = -49 + 35

-14 = -14 True

The number is (- 7).

Hello,

Step-by-step explanation:

y-intercept: x=0 ,f(0)=-10

$x^3-8x^2+17x-10\\\\=x^3-5x^2-3x^2+15x+2x-10\\\\=x^2(x-5)-3x(x-5)+2(x-5)\\\\=(x-5)(x^2-3x+2)\\\\=(x-5)(x^2-x-2x+2)\\\\=(x-5)(x(x-1)-2(x-1))\\\\=(x-5)(x-1)(x-2)\\$

x-intercepts are: 5,1,2.

Andrew has a four-year college loan for $20,000. The lender charges a simple interest rate of 5 percent. How much interest will

Olegator [25]

Given that loan amount P=20000

Interest rate r=5% = 0.05

Time of loan t=4 years

Now to find the interest amount we just plug those values into formula

simple interest = P × r × t

simple interest = 20000* 0.05* 4

simple interest = 1000 * 4

simple interest = 4000

Hence final answer is choice b. $4000.
