Step-by-step explanation:

the answer would be 2 years

explanation:

$1= $ 30 P = $500$

p= 3% = 0.03

I = PRT

30 = 500 · 0.03 ·t

Substitute

30 = 15t Multiply.

30/15=15/15

divide both sides by 15.

t=2

Answer:

6w-66

Step-by-step explanation:

We can use the distributive property by multiplying the number outside the parentheses to each term inside the parentheses. So we have (w-11)6 = 6*w-6*11 = 6w-66.  

Answer:

Hey There!

Let's solve....

Isolate for x first which is

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

\(substitute \: x = \frac{3 + 3y}{4} \\ \\ \brack \: 5 \times \frac{3 + 3y}{4} - 4y = 3 \\ \\ \)

Now simplify...

\( \brack \: \frac{15 - y}{4} = 3 \\ \\ = y = \frac{15 - 3}{4} \\ \\ = \frac{12}{4} \\ simplify \\ \\ \frac{ \cancel{12} ^{3} }{ \cancel{4}^{1} } \\ x = 3\)

Y=3

We need to find value of y first... now x

\(x = \frac{3 + 3 \times 3}{4} \\ \\ =x = \frac{3 + 9}{4} \\ \\ = x = \frac{12}{4} \\ simplify \: \frac{ \cancel{12}^{3} }{ \cancel{4} ^{1} } \\ \\ value \: of \: x = 3 \)

Answer:

x = -1.3

I hope this is right, and I am sorry if this is wrong if it is! I rlly hope this helps you out and you can understand my method and the way I typed this!!

Step-by-step explanation:

We are going to use one of my fav methods! The substitution method!

Set this aside for now: 4x - 3y = 3     We gonna use this one: 5x - 4y = 3

5x - 4y = 3

= 5x - 3 = 4y

( also, the subtraction is with the 4y as a negative, so 4y would be positive if you moved it!)

Divide all of the equation by 4!

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

Now, you take take the other equation and substitute the y with what you have above!

\(4x - 3 times \frac{5x - 3}{4} = 3\)

you cross multiply 4( the denominator) with the other side that has only a three!

4x - 3 \(times 5x - 3\) = 12

4x - 15x - 3 = 12

-11x - 3= 12

Move the three to the other side become positive!

-11x = 15

divide both sides by -11

x = -1.3

Kilometers to Miles:

For an approximate result, divide the length value by 1.609

The answer is b cause i took the test

Answer:

(1/4) hr/mile

Step-by-step explanation:

4 mph can be rewritten using other units of measurement:

Suppose we convert 'miles' to 'feet:'

Then:

4 miles     5280 ft

---------- * ------------- = 21120 ft/hr

     1 hr        1 mile

Note that we could invert 4 mph and obtain

 1 hr

-------- or (1/4) hr/mile

4 mi

Firstly, you have to understand that if you talk about slope is a similar word gradient of the graph. So if you are calculating slope you have to use gradient formula:

m= Y2-Y1

X2-X1

therefore, in order for you getting first box & second box you have to use this formula above.

First box answer is:

Points fromthegraph (-2:-2) & (-3:-3)

m= Y2-Y1

X2-X1

m = -3-(-2)

-3-(-2)

m = 1

Second box answer is:

Points fromthegraph (3:3) & (4:4)

m= Y2-Y1

X2-X1

m= 4-3

4-3

m= 1

Third box answer is:

= 4

Forth box answer is:

Answer:

The properties of the parabola equation are

Vertex = (-5, -4)

Roots = (-7, 0) and (-3, 0)

Points = (-2, 5) and (-4, -3)

What are parabola equations?

Parabola equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

How to plot the graph of the parabola?

The equation is given as

y = x^2 + 10x + 21

Next, we plot the graph on the coordinate plane

On the graph, we can see the following properties

Vertex = (-5, -4)

Roots = (-7, 0) and (-3, 0)

Points = (-2, 5) and (-4, -3)

× x = 190

Multiplying both sides by 100 and dividing both sides by 38,

we have x = 190 ×

x = 500

If you are using a calculator, simply enter 190×100÷38, which will give you the answer.

Step-by-step explanation:

Use a conversion factor of 1 mph = 1.609 kph to solve the problem.

Answer:

35.40

Step-by-step explanation: Therefor 35:40 is the answer!

(1 mile per hour = 1.609 kilometer per hour)

Answer:

Graph 3

Step-by-step explanation:

equation: y = mx + b → y = 1/3x - 4

- m is the slope (slope = rise / run):

- b is the y intercept (when x = 0): -4

Graph 1 is incorrect because the y-intercept is 1.5 on this graph when the equation is -4

Graph 2 is incorrect because the slope is 3 / 1, the rise is 3 and the run is 1

the correct equation for this graph is y = 3x - 4

Graph 3 is correct because the slope is 1/3, the rise is 1 and the run is 3

and the y intercept is -4

Graph 4 is incorrect because the y-intercept is not even shown
