To the nearest whole: 4
to the nearest hundredth: 4.2
actual answer: 4.5
Answer:
x = 5.4
Step-by-step explanation:
Since A is the scale image of B,
4/3 = 7.2/x
Cross multiplying,
4x = 3*7.2
Dividing by4,
x = 3*7.2 / 4
x = 5.4
Answer:
They are perpendicular.
Step-by-step explanation:
When we convert the equation 6x-2y=-5 into y=mx+b form, it changes into y=3x-5/2. Since we know that perpendicular slopes are opposite reciprocal, the opposite reciprocal of -x/3 is 3. So, we know that these 2 slopes are perpendicular.
Its 157, because 180-23= 157 degrees.
Answer:
(10,0)
Step-by-step explanation:
When it comes to rotations by 90 degrees or 270 degrees, you just have to switch the order of x- and y- coordinates. Then find the sign by considering which quadrant will it be. In this case, it is originally on the positive y-axis and now it would be +ve x-axis.
