Answer:
A = 21
Step-by-step explanation:
Hello
The triangle area is= (base*height)/2, so
A = (6*7)/2
A = 42/2
A = 21
Remember that a trinagle is the area of half square =D
Best regards
Answer:
-4x
Step-by-step explanation:
-8x + 4x = -4x
Answer:
Step-by-step explanation:
You can solve this two ways: insert the values into point-slope form and simplify to solve for y, converting it to slope-intercept form, <em>or</em><em> </em>insert the values into slope-intercept form, solve for b, and insert b. We'll do both :)
<em><u>Point-slope form:</u></em>
Where:
- is the slope
- and are corresponding coordinate points
Insert the given values:
Solve for y. Expand the right sie using the distributive property:
Isolate the variable. Subtract 6 from both sides, canceling out the 6 on the left:
<em>OR</em>
<em></em>
<em><u>Slope-intercept form:</u></em>
Where:
- is the slope
- is the y-intercept
- and are corresponding coordinate points
Insert the given values:
Simplify the multiplication:
Solve for b. Add 10 to both sides, canceling out the 10 on the right:
The value of b is 4. Insert the appropriate information into the equation. When using slope-intercept form, you don't plug in the coordinate points:
:Done
Answer:
Step-by-step explanation:
Given
Required
Express as x/y
Let
This implies that:
--- (1)
Multiply by 100
--- (2)
Subtract 1 from 2
This gives
So:
Solve for x
This implies that:
becomes
Express 0.6 as fraction
Take LCM and solve
