The angle the radius makes with AB is a right angle, so the Pythagorean theorem applies.
r² = 17.4² - 7² = 253.76
r = √253.76 ≈ 15.9

The length of radius r is about 15.9.

X - y = 6

Dominik [7]

the system has no solution.

Option C is correct.

Step-by-step explanation:

We need to solve the system of equations by substitution

$x - y = 6\,\,\,eq(1)\\x = y + 2\,\,\,eq(2)$

Putting value of x from eq(2) into eq(1)

$(y+2)-y=6\\y+2-y=6\\0+2=6\\0=6-2\\0\neq4$

As as 0≠4is not true, we cannot find the value of y so the system has no solution.

Option C is correct.

Steve opens a bank account with a simple annual interest rate of 5%. After four years, how much interest will Steve earn on an i

Marysya12 [62]

Steve will earn $160 interest after four years ⇒ 1st answer

Step-by-step explanation:

The formula of the simple interest is I = Prt, where

P is the initial deposit
r is the annual rate in decimal
t is the time of investment

∵ Steve opens a bank account with a simple annual interest rate of 5%

∴ r = 5% = 5 ÷ 100 = 0.05

∵ His initial deposit is $800

∵ He will put the money for four years

∴ t = 4

- Substitute all these values in the formula above

∵ I = 800(0.05)(4)

∴ I = 160

Steve will earn $160 interest after four years

If x = -3 and y = 4x - 1, then y equals what number

Masteriza [31]

$\huge\text{Hey there!}$

$\large\textsf{y = 4x - 1}$

$\large\text{If x= -3, then substitute it into the given equation}$

$\large\textsf{y = 4(-3) - 1}$

$\large\textsf{4(-3) = \boxed{\bf -12}}$

$\large\textsf{y = -12 - 1}$

$\large\textsf{-12 - 1 = y}$

$\large\textsf{-12 - 1 = \boxed{\bf -13}}$

$\boxed{\boxed{\large\textsf{Answer: \huge \bf y = -13}}}\huge\checkmark$
