Answer: No solution

When an equation has infinitely many solutions, it is the exact same equation on both sides. For example, for this to be infinitely many, it would have to be:

5c+9=5x+9

This would be infinitely many, because it would be the same line plotted twice, so it would have an infinite amount of intersecting points.

This also cannot be one solution, because they have the same slope. When an equation has the same slope, it can either be infinitely many solutions or one solution. We already explained why this is not infinitely many, but it is also not one solution. If plotted, these points could never intersect. For this to be one solution, it would have to be:

5c+9=4c-12

This means the equation has no solution. It will never intersect. Let’s prove this by solving:

5c+9=5c-12

*subtract 5c on both sides*

9=-12

Since this is not true and 9 does not equal -12, there is no solution

Answer:

The answer is no solution.

Step-by-step explanation: First, you would add + 12 to both sides of the equation so that you would have 5c + 21 = 5c. Then, you would subtract 5c from both sides of the equation. This would leave you with 21 = 0. Since this is not true, the equation would have no solution.

A jet travels 470 miles in 2 hours. At this rate, how far could the jet fly in 15 hours? What is the rate of speed of the jet?
Gennadij [26K]

Answer:

The jet could fly 3,525 miles in 15 hours.

The rate of speed is 235 miles an hour.

Step-by-step explanation:

Step 1- Find the rate of speed

470÷2= 235

235 miles an hour

Step 2- Multiply

235×15= 3,525

A bank loaned out $14000, part of it at the rate of 9% per year and the rest at 17% per year. If the interest received in one ye
WINSTONCH [101]

Using simple interest, it is found that $13,872 was loaned at 9%.

<h3>Simple Interest</h3>

The amount of money after t years in simple interest is modeled by:

A(t) = P(1 + rt)

In which:

  • P is the initial amount.
  • r is the interest rate, as a decimal.

The interest earned is:

I(t) = Prt

A bank loaned out $14000, in two parts, hence:

P_2 = 14000 - P_1

Part of it at the rate of 9% per year and the rest at 17% per year, hence:

r_1 = 0.09, r_2 = 0.17

The interest received in one year totaled $2000, hence:

I_2 = 2000 - I_1

Then:

I_1 = 0.09P_1

I_2 = 0.17I_2

14000 - P_1 = 0.17(2000 - I_1)

Isolating I_1 as a function of P_1, then we can replace on the equation for the first interest.

14000 - P_1 = 340 - 0.17I_1

0.17I_1 = -13660 + P_1

I_1 = \frac{P_1 - 13660}{0.17}

Then:

I_1 = 0.09P_1

\frac{P_1 - 13660}{0.17} = 0.09P_1

P_1 - 13660 = 0.0153P_1

0.9847P_1 = 13660

P_1 = \frac{13660}{0.9847}

P_1 = 13872

$13,872 was loaned at 9%.

Not sure if y-2x=10 or y-2x=-10

I'll solve both
later you will see that 10 or -10 is irrelevant

find slope first since perpendicular lines have slopes that multiply to -1
the slope from form ax+by=c is -a/b
-2x+y=?
slope=-(-2)/1=2


perpendicualr
2 times what=-1
what=-1/2

y=mx+b
m=slope
we know slope is -1/2
y=-1/2x+b
find b
subsitut eht point (9,-5)
(x,y)
x=9 and y=-5
-5=-1/2(9)+b
-5=-9/2+b
add 9/2 to both sides
-1/2=b

the equation is
y=-1/2x-1/2
