Answer:
{y,x} = {0,1}
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = 3x - 3
// Plug this in for variable y in equation [2]
[2] -3•(3x-3) - 9x = -9
[2] - 18x = -18
// Solve equation [2] for the variable x
[2] 18x = 18
[2] x = 1
// By now we know this much :
y = 3x-3
x = 1
// Use the x value to solve for y
y = 3(1)-3 = 0

The Angle-Side-Angle Postulate (ASA)
Step-by-step explanation:
Suppose that after 10 years of service, 40% of computers have problems with motherboards (MB), 30% have problems with hard drives (HD), and 15% have problems with both MB and HD.
(a) Are the events A have problems with motherboards" and B have problems with hard drives independent? Why or why not?
(b) What is the probability that a 10-year old computer still has fully functioning MB and HD?

Alberto has a scale drawing of an object whose area is 12 square centimeters. The scale factor is 1:3 Alberto says that the area of a real object is 36 square centimeters is Alberto's answer is correct.
WIL GIVE GIVE BRAINLIEST LOTS OF POINTS
Answer:
No, Albert's answer is not correct
Step-by-step explanation:
For illustrative purposes, let's say the object is a rectangle with width 2cm and length 6cm.
Therefore, area = width x length = 2 x 6 = 12 cm²
If the scale factor is 1 : 3, then each side of the real object should be 3 times larger than the scale drawing.
So the width = 2 x 3 = 6 cm
and the length = 6 x 3 = 18 cm
Therefore, the area of this rectangle would be 6 x 18 = 108 cm²
So the scale factor of the area is: 12 : 108 = 1 : 9
so Alberto's answer is incorrect, as 12 : 36 is NOT 1 : 9

need to show work!!!
Answer:
9
Step-by-step explanation:
Since you have a right triangle, you can use the Pythagorean theorem.
a² + b² = c²
x² + 5² = 10²
x² + 25 = 100
x² = 75
x = √75
x = 5√3 = 8.66...
x = 9
The height of a tower on a scale drawing is 14 centimeters. The scale is 2 cm : 29 m. What is the actual height of the tower?
Answer:
203 m
Step-by-step explanation:
Set up a proportion and solve it.
drawing size : real size
14 cm : x
2 cm : 29 m
14/x = 2/29
2x = 14 × 29
x = 7 × 29
x = 203
Answer: 203 m

Answer:
28.4
Step-by-step explanation:
IJ corresponds to FG, and JK corresponds to GH. So, x/6 = 52/11. 11x = 312, x = 28.36, which rounds to 28.4

IPASS Corn Maze 2
Tina and her family live on a farm. Each summer
they design and plant a corn maze for local
children to enjoy in the autumn. This year Tina
is designing the maze. Here are the details of
her proposed design.
The corn is to be planted in four
concentric
circles as shown in the diagram.
The radit of the circles of corn are as marked
in the diagram
A 3-Foot arc of each circle of corn will not be
planted, as shown in the picture.
+
Tina's parents want to make a gravel walkway
that will extend 6 feet from the outer circle of
the maze all the way around the maze. Find the
area of the walkway. Round your answer to the
nearest square foot, if necessary.
10 ft
420 ft
30 ft
-40 ft
Answer:
460 ft long because if you add them all together and minus 40 that what you should get
Select the equation in slope-intercept form for the line through points (5, - 3) and (10, - 2) and is perpendicular to the line described by y = - 5x + 4
Answer:
y = x/5 - 4
second option is the correct answer.
Step-by-step explanation:
y = -5x+4
y = mx+b
m = -5
Now
Slope of the line perpendicular to a line would be the negative proprtional of the slope of the line.
so,
For the points (5,-3) and (10,-2)
m = 1/5
y = mx + b
or, -3 = 1/5 × x + b
or, -3 = 1/5 × 5 + b
or, -3 = 1+b
so, b = -4
Now,
y = mx+b
or, y = 1/5 × x + (-4)
or, y = x/5 - 4
