Can I get help please? <br>5b+4+10=-2

rjkz [21]

5b+4+10=-2

5b+14=-2

5b+14-14=-2-14 1) subtract 14 from both sides

5b=-16

5b/5=-16/5 2) divide by 5 on both sides

b=3 & 1/5

WRITE AN EQUATION TO DESCRIBE THE RELATIONSHIP BETWEEN J AND Mj | 4 | 12 | 20m | 3 | 9 | 15

galina1969 [7]

First, we can use the points (4,3) and (20,15) to find the slope of the line:

$\begin{gathered} s=\frac{m_2─m_1}{j_2─j_1}=\frac{15─3}{20─4}=\frac{12}{16}=\frac{3}{4} \\ s=\frac{3}{4} \end{gathered}$

Now we can find the relation function using the point (4,3) and the slope s=3/4

$\begin{gathered} m─m_1=s(j─j_1) \\ \Rightarrow m─3=\frac{3}{4}(j─4)=\frac{3}{4}j─(\frac{12}{4})=\frac{3}{4}j─3 \\ m=\frac{3}{4}j \end{gathered}$

therefore, the equation to describe the relationship between J and M is m=3/4j

Find the value of x so that the polygons have the same perimeter.

Novosadov [1.4K]

Answer: x=4

Step-by-step explanation:

The perimeter´s formula for this kind of polygons is

The triangle perimeter would be:

(x+2)+(x+3)+(x+3)

And the rectangle:

(x+2)+(x+2)+x+x

For them to have the same value, we should equal them:

(x+2)+(x+3)+(x+3)=(x+2)+(x+2)+x+x

Working with this:

3x+8=4x+4

x=4
