d1i1m1o1n [39]

Answer:

x=20

Step-by-step explanation:

We can use similar triangle to find x.  Put the smaller triangle over the larger triangle.

11             10

-------- = ----------

121+11       10 +5x+10

Combine like terms

11             10

-------- = ----------

132       20+5x

Using cross products

11 (20+5x) = 132*10

Distribute

220 +55x = 1320

Subtract 220 from each side

220-220 +55x = 1320-220

55x = 1100

Divide by 55

55x/55= 1100/55

x =20

Determine the intercepts of the line
dusya [7]

Answer:

y-intercept: (0, -0.7)

x-intercept: (-1.2, 0)

Step-by-step explanation:

  • To find the x-intercept (x, 0) of a line substitute y by zero in the equation of the line, and from the graph, it is the point of intersection between the line and the x-axis
  • To find the y-intercept (0, y) of a line substitute x by zero in the equation of the line, and from the graph, it is the point of intersection between the line and the y-axis

In the given figure

∵ The line intersects the y-axis at the point (0, -0.7)

∴ The point of intersection between the line and the y-axis is (0, -0.7)

→ By using the 2nd note above

∴ The y-intercept is (0, -0.7)

∵ The line intersects the x-axis at the point (-1.2, 0)

∴ The point of intersection between the line and the x-axis is (-1.2, 0)

→ By using the 1st note above

∴ The x-intercept is (-1.2, 0)

Need help with this please
Crazy boy [7]

Answer:

1. 2(k + 3)

2. 3. 75 + k

Step-by-step explanation:

1. 2x + 6

Since, 2 is a common factor of 2 and 6, we can take that common outside.

So, 2x + 6 = 2(x + 3)

Note that in the initial expression, this 2 was distributed to arrive at 2x + 6.

2. (1.5 + k) + 2.25

This is simple addition. We can simply remove the brackets to have:

1.5 + k + 2.25

Since, the like terms can be added, we will have:

1.5 + 2. 25 + k

= 3. 75 + k

4x+32=24<br> show your work
sp2606 [1]

Answer:

x = -2

Step-by-step explanation:

Original equation:

4x + 32 = 24

Subtract 32 from 24

-8

The equation should look like this now:

4x = -8

Divide both sides by 4

x = -2

Hope this helps :)
