Answer:
( 5 , 2)
Step-by-step explanation:
The coordinates of T can be found as
[ 1 + (2/3)(7 - 1) , 4 + (2/3)(1 - 4) ] =
[ 1 + (2/3)(6) , 4 + (2/3)(-3) ] =
[ 1 + 4. 4 - 2 ] =
( 5 , 2)
Step-by-step explanation:
Let EF and GH are the two lines segment of length a and b such that a> b
We can construct line AB by using ruler and compasses.
- Step 1: Draw a line longer than the combined length of EF + GH or (a+b) and mark a point A on it
- Step 2: Using a compass, cut a line segment AC on line l equal to the length of EF by keeping its metal point of A
- Step 3: Using a compass, cut a line segment BC on line l equal to the length of EF by keeping its metal point of B
- Step 4: Using a compass, cut a line segment AH online AC equal to haft of the length of AC
=> we have a line segment with length equal to (EF+GH)/ 2
Hope it will find you well.
Answer:
y = -1/5x + 6.4
Step-by-step explanation:
Use the point-slope formula.
y-y₁ = m(x -x₁)
so...
y-7 = -1/5(x - (-3))
y = -1/5x+ 32/5
and you need you can change 32/5 to 6.4
Hope this helps!
Answer:
<h2>170</h2><h2 />
Step-by-step explanation:
given:
Ann, Ben, and Cindy were eating strawberries.
The ratio of the numbers of berries they ate is 5:5:7.
If Cindy ate 30 strawberries less than Ann and Ben together,
find:
what is the total number of strawberries the three of them ate?
solution:
add the ratios 5 +5+7 = 17
since Cindy ate 30, less than Ann and Ben together so, the factor is
7x = 5x + 5x - 30
7x - 10x = -30
x = 30/3
x = 10
ann 5 x 10 = 50
ben 5 x 10 = 50
cindy 7 x 10 =<u> 70
</u>
total = 170
