Answer:
b=-6.8
Step-by-step explanation:
multiply both sides by -2 to get rid of the denominator.
Use the pythagorean theorem A²+B²=C²
Use 21ft for A
Use 14ft for B
Then solve for C (the diagonal)
21²+14²=C²
441+196=C²
673=C²
√<u />673 = √C²
C≈25.24 or if you leave in radical form it is the square root of 637
Answer:
x=13
Step-by-step explanation:
15x-15
15*13=195
195-15=180
Answer:
3rd option, $672
Step-by-step explanation:
The area is,
(4×12)+(8×10)
= 128
per square foot it costs $5.25, so the total cost will be,
128×$5.25
= $672

Answer:
The coordinates of image are : (-3,4) , (-8,2) and (-4,7)
Step-by-step explanation:
The rule is given as (x, y) —> (-x,y)
The coordinates of the triangle are : (3,4) , (8,2) and (4,7)
The coordinates of the image of the triangle will be : (-3,4) , (-8,2) and (-4,7)
Graphing the coordinates of image and connect the points to get the image of the triangle as attached below;
You will notice the rule of the transformation is a reflection along the y-axis.
