The first one is D. 12(3x+1)
Is there a 4th option for question 2
Reflecting DEF on the y-axis gives the following coordinates of D'E'F' as follows
the coordinate of D' (-2, 2)
the coordinate of E' (2, -1)
the coordinate of F' (3, 5)
Translating D'E'F' by the vector (3, -5) gives the following coordinate of D''E''F'' as follows
the coordinate of D'' (-2+3, 2-5) = (1, -3)
the coordinate of E'' (2+3, -1-5) = (5, -6)
the coordinate of F'' (3+3, 5-5) = (6, 0)
The diagram below shows the transformation of triangle DEF
Answer:
D
Step-by-step explanation:
The shortest side is the side opposite the smallest angle, the longest side is opposite the largest angle.
First find the measure of the angles in the triangle.
The sum of the 3 angles = 180° then
5x + 40 + 10x + 7x + 8 = 180
22x + 48 = 180 ( subtract 48 from both sides )
22x = 132 ( divide both sides by 22 )
x = 6
Then
∠ A = 7x + 8 = 7(6) + 8 = 42 + 8 = 50°
∠ B = 5x + 40 = 5(6) + 40 = 30 + 40 = 70°
∠ C = 10x = 10(6) = 60°
The shortest side is opposite ∠ A , that is BC
The longest side is opposite ∠ B , that is AC
The sides in order from shortest to longest are
BC, AB, AC → D
Answer:
135=15m+25 OR 15m+25=135
Step-by-step explanation:
To set this equation up you want to look at key words. It states that "Karina now saved $135" in meaning her total saved. Now it states she STARTED the account with 25 so that would be added to the amount she adds per month (which is $15). The equation can be set up as 15m+25=135. 15m because m stands for every month she added $15, 25 because she started the account with 25 and 135 because that's her total after the several months.
Hi there.
100 mph; how long would it take to drive 211 miles?
The answer here is rather simple. Divide 211 by 100 to determine how many hours it will take.
211 / 100 = 2.11
This means it will take 2 11/100 (or 2.11) hours to drive 211 miles.
I hope this helps!
