subtracting term by term
(3.1x - 4.3x ) + (2.8z - (- 1.2z ) )
= - 1.2x + (2.8z + 1.2z ) = - 1.2x + 5z
Answer:
Step-by-step explanation:
Corresponding parts of congruent triangles are congruent.
So, XY = AB
3a - 3.9 = 1.7a - 1.3
3a = 1.7a - 1.3 + 3.9
3a = 1.7a + 2.6
3a -1.7a = 2.6
1.3a = 2.6
a = 2.6/1.3
a = 2
ΔABC ≅ ΔXYZ
First two letter
AB = XY
Second and third letters
BC = YZ
Third and first letter
CA = ZX
Answer:
f(5).g(5)
Step-by-step explanation:
(fg)=(f.g)
this is how it starts: (fg)(X)= f(x) [g(x)]
x=5
f(5).g(X)
The equivalent ratios for 6:7 is 12:14 because 12/14 is equivalent to 6:7.The ratios for 14:28 is 1:2. The ratio for 27:9 is 3:1. The ratio for 15:12 is 5:4. Last but not least the ratio for 35:40 is 7:8.
Answer:

Step-by-step explanation:
To start, you need to find the equation of both of these lines. For the orange one, the slope can be found with the points (-5,0) and (0,-4), where there is a drop of 4 for a run of 5. This is a slope of -4/5, and a y-intercept of -4. For the purple line, you can use the points (-2,0) and (0,1), where there is a rise of 1 for a run of 2 or a slope of 1/2 and a y intercept of 1. Therefore, the two equations are:


You can now set them equal to each other:

Add 4 to both sides:

Multiply both sides by 2:

Multiply both sides by 5:

Subtract 5x from both sides:

Divide both sides by -13:
