As the x value increases by 1, the y value increases by 4. If the x value skips from 4 to 25, it increaes by 21. The y value can be found by multiplying 21 * 4 and adding the previous y value, 7. 21 * 4 is 84 and 84 + 7 = B) 91
Answer:
The length of side AC is 5 units.
The areas of triangle ABC is 10 square units.
Step-by-step explanation:
From point A (1,3) to point C (1,-2) is 5 units
To check this:
3 - (-2) = 3 + 2 =5
We're subtracting since the point went down (from positive 3 to negative 2)
Now for the area:
Area formula for a triangle:
bh =
⋅b⋅h
We already found the height (length) : 5
The base is from point C (1,-2) to point B (5,-2), which is 4 units
To check this:
5 - 1 = 4
Now that we have found the base and height, Let's solve:
⋅4⋅5 =
⋅20 = 10
Our area is 10 square units.
Hope that helps :)
Answer:9.0875
Step-by-step explanation:
[2.4–(0.3–3.21)÷2+0.44÷(−2)]÷ 2/5=
[4.8:2-(-2.91):2-0.44:2]:2/5=
=[(4.8+2.91-0.44):2]*5/2=
=[(7.71-0.44):2]*5/2=
=(7.27:2)*5/2=(7.27*5):(2*2)=
=36.35:4=9.0875
Should be a scale factor of y= 1/9
4/6
As there are 4 numbers on the dice and there are 6 numbers all together on a dice.
Hope this helps
