what is the answer to this question 13 + 3p = 7

Answer:

The only single-digit prime numbers are: 2, 3, 5, and 7.

Answer:

2, 3, 5, 7

Step-by-step explanation:

1) Prime numbers are numbers that can only be multiplied by themselves and one; therefore, they only have two factors.

Hope this helps!

y is the dependent variable and x is the independent variable.

Hey there! I'm happy to help!

This is slope intercept form: y=mx+b, where m is the slope and b is the y intercept. The slope is what is multiplying x. In our case, 2.83 is multiplying x, so 2.83 is the slope.

Given :

Rain is falling at 0.5 inches per hour and 1.5 inches have already accumulated.

To Find :

How many hours must have passed if there are 5 inches of rain .

Solution :

Let , after x hours rain accumulated is 5 inches .

We know , general equation of line :

y = mx +c

Here , m = 0.5 and c = 1 .

So , equation of rain accumulated is :

[tex]y=0.5x+1[/tex]

Now , putting value of x = 5 hours .

We get :

[tex]y=0.5\times 5+1\\\\y=2.5+1=3.5\ inches[/tex]

Hence , this is the required solution .

Answer:

0.5h+1.5=5

1.5h+0.5=5

Answer:

3 is correct answer

Step-by-step explanation:

[tex]3(x - 2) + 5x = 18 \\ 3x - 6 + 5x = 18 \\ 8x - 6 = 18 \\ 8x = 18 + 6 \\ 8x = 24 \\ x = \frac{24}{8} \\ x = 3[/tex]

Answer:

x=3

Step-by-step explanation:

3x-6+5x=18

add the same terms to both sides

8x-6=18

add the term again

8x-6+6=18+6

8x=24

8x/8 24/8

x=3

Answer:49

Step-by-step explanation:

Step-by-step explanation:

y = 0x - 1.

Slope of the line = 0.

A line that is parallel to the original line must have the same slope, which is 0.

y = 0x + c.

When x = 8, y = -4.

-4 = 0(8) + c. So c = -4.

Hence the equation of the parallel line is y = -4.

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

D(-4,4), X(-2, 2)

The midpoint is

[tex]M = ( \frac{ - 4 - 2}{2} \: , \: \frac{4 + 2}{2} ) \\ = ( - \frac{ 6}{2} , \frac{6}{2} )[/tex]

We have the final answer as

Answer:

Rational

Step-by-step explanation:

2.7 can be written as a fraction, so therefore it is ration[tex]2.7=2\frac{7}{10} =\frac{27}{10}[/tex]al.

The number 2.7 is a rational number.

A rational number is a number that can be expressed as a ratio of two integers, where the denominator is not zero.

In other words, a rational number can be written in the form p/q, where p and q are integers, and q is not equal to zero.

Now, let's express 2.7 as a fraction:

2.7 = 27/10

Since 27 and 10 are both integers, and the denominator (10) is not zero, we have successfully expressed 2.7 as a fraction of two integers.

Therefore, 2.7 is a rational number.

On the other hand, an irrational number cannot be expressed as a simple fraction of two integers. Examples of irrational numbers include π (pi) and √2 (the square root of 2).

These numbers have non-repeating and non-terminating decimal expansions, and they cannot be written as a fraction of two integers.

However, 2.7 is a terminating decimal (it has a finite number of decimal places), and it can be expressed as a fraction, making it a rational number.

As we look at both triangles, we can see that they have a few things in common.

Each triangle shares a right angle, one leg, and an acute angle.

LL = leg and leg

HA = hypotenuse and angle

HL = hypotenuse and leg

LA = leg and angle

The triangles do not share two legs, nor do they share a hypotenuse.

Therefore,

LA is the only choice that makes sense.

For these two right triangle, LA(Leg and angle) verifies that ΔDEF ≅ ΔSTU.

If the hypotenuse and a side of a right- angled triangle is equivalent to the hypotenuse and a side of the second right- angled triangle, then the two right triangles are said to be congruent.

In these two given right triangles, ∠D = ∠S and ∠F = ∠U.

Therefore, the third angle of each triangle are equal as per the third angle theorem.

The leg of each triangle is equal as mentioned.

Therefore, LA(Leg and angle) verifies that ΔDEF ≅ ΔSTU.

Answer:

Step-by-step explanation:

Easy way: type the equation into a graphing calculator.

__

By hand: find a couple of points and draw a line through them.

The equation is in "slope-intercept" form:

  y = mx + b

where m is the slope (-2) and b is the y-intercept (3). The y-intercept is where the line crosses the y-axis, so right away you know one point on the line. That point is (0, 3).

The slope of -2 means for each horizontal unit, the line drops 2 units vertically. The point 1 unit to the right of (0, 3) is (1, 3); and the point 2 units below that is (1, 3-2) = (1, 1). So, another point on the line is (1, 1).

You can plot those two points and draw the line through them.
