2(x+5)+6x = 8x+10 One Solution No Solution Many Solutions

Mama L [17]

Step-by-step explanation:

2(x + 5) + 6x = 8x + 10

2x + 10 + 6x = 8x + 10

8x + 10 = 8x + 10

Since this equality is true for any real values of x, there are infinitely many solutions for x.

The best answer here is "Many Solutions".

Select the equation in which you use the inverse property of multiplication to find the solution.

loris [4]

Given:

Equations using properties.

To find:

The equation which use the inverse property of multiplication.

Solution:

<u>Inverse property of multiplication:</u>

<em>The product of any number and its reciprocal is always 1.</em>

Let us select the option which uses inverse property of multiplication.

Option A: $\left(\frac{3}{4} \cdot \frac{4}{3}\right)+7=8$

Inverse of $\frac{3}{4}$ is $\frac{4}{3}$ . Their product is 1.

$$\frac{3}{4} \cdot \frac{4}{3}=1$

This equation uses the inverse property of multiplication.

Option B: $\left(-\frac{7}{8}+\frac{7}{8}\right)+4=4$

Inverse of $\frac{-7}{8}$ is $\frac{8}{-7}$

So, it is not true equation.

Option C: $(-5 \cdot 0)-9=-9$

Inverse of $-5$ is $-\frac{1}{5}$ .

So, it is not true equation.

Option D: $\left[7 \cdot\left(\frac{5}{7}-\frac{4}{7}\right)\right]+8=9$

Here also inverse property is not used.

So, it is not true equation.

Hence the equation use the inverse property of multiplication is

$$\left(\frac{3}{4} \cdot \frac{4}{3}\right)+7=8$ .

What are the slope and y intercept of the linear function? Please help

kow [346]

FIND THE SLOPE
The line passes through (0,1) and (2,0)
Use formula of the slope to find the slope
m = (y₂ - y₁)/(x₂ - x₁)
m = (0-1)/(2-0)
m = -1/2
The slope is -1/2

FIND THE Y-INTERCEPT
The y-intercept is the value of y when the line intersects y axis. The line intersects y axis in point (0,1). The value of y is 1. So the y-intercept is 1.
