Two step inequalities 5x-7_>8

Naddik [55]

Answer:

x ≥ 3

Step-by-step explanation:

5x - 7 ≥ 8

5x ≥ 8 + 7 (You take the common terms to one side)

5x ≥ 15

$\frac{5x}{5} \geq \frac{15}{5}$

x ≥ $\frac{15}{5}$

x ≥ 3

(2/7)-² ÷ 2² = <br>pls answer

Nataly_w [17]

Answer:

$\frac{4}{98}$

Step-by-step explanation:

→ Simplify the (2/7)² term

$(\frac{2}{7} )^{2} =\frac{2}{7} *\frac{2}{7}=\frac{4}{49}$

→ Simplify the 2² term

$2^{2} =2*2=4$

→ Evaluate

$\frac{4}{49} /2=\frac{4}{49} *\frac{1}{2} =\frac{4}{98}$

Write a system of two equations in two variables where one equation is quadratic and the other is linear such that the system ha

PilotLPTM [1.2K]

Answer:

This system has no solution:

y = x²

y = 0 · x - 1

Step-by-step explanation:

Hi there!

I propose these two equations:

y = x²

y = 0 · x - 1

This system has no solution because in the quadratic function "y" is always positive for every value of "x", while in the linear function "y" is always -1 for every value of "x". Then, there will not be a pair (x,y) shared by both functions.

In other words, there is no value of "x" that satisfies this expression:

x² = 0 · x - 1

In the attached graphic, you can see that both curves never touch (in red is the quadratic function and in blue is the linear function), hence, the system has no solution.

Have a nice day!

Principal: $4,000 at 6% for a) 4 years, b) 4 months, and c) 4 days.

ZanzabumX [31]

Answer:

If you're asking for the interest:

a) 960

b) 80

c)2.63 approx.

Step-by-step explanation:

interest = principal x rate x time OR $I = prt$

TIME IS IN YEARS.

Thus, the first would be $I = 4000 *4 *6%$ % = 960

Second: 4 months = $\frac{1}{3}$ year

I = 4000x $\frac{1}{3}$ x6% = 80

Third: t = 4 days = $\frac{4}{365}$ year

I = 4000x6%x $\frac{4}{365}$ ≈ 2.63
