1. Is -7 + 9= -9 + 7 true, false, or open

Mathematics

Inessa [10]3 years ago
7 0
1. -7 + 9= -9 + 7 is false 
2. Is 4x - 3 = 19 is open, because this could be a valid equation.
 3. 16 = 4x - 4 
  So, 16+4=4x; 4x=20; x=20/4; x=5..... option C is the correct one.
 4. length of the classroom is 2.4 times its width. 
  given length = 42 in, and since length = 2.4 times width, width = 42/2.4,
hence option A) 17.5 in is correct
 5. x - 3 = 10
  x = 10+3 =13
 Option B is the right one.

According to these three facts, which statements are true?
sveticcg [70]
We have that

1)<span>Circle W has center (−3, 0) and radius 8
the equation of a circle W is
(x+3)</span>²+(y)²=8²

2)<span>Circle V is a translation of circle W, 2 units down.
the center of circle V--------> (-3,0-2)---------> (-3,-2)

3)</span><span>Circle V is a dilation of circle W with a scale factor of 2.
then the radius circle V is 8*2------> 16 units
</span>the equation of a circle V is
(x+3)²+(y+2)²=16²

therefore

 case <span>A. Circle V and circle W are similar.---------> is correct
</span>because  I can transform circle V to circle W using only translations, rotations and scaling  (In the case of circles, no rotations are necessary).

case <span>B. Circle V and circle W have the same center.-------> is not correct

case </span><span>C. The radius of circle V is 16.-----------> is correct

case </span><span>D. The center of circle V is (−5, 0).----------> is not correct


the answer is
</span> case A. Circle V and circle W are similar.---------> is correct
 case C. The radius of circle V is 16.-----------> is correct

Equivalent fractions for 15/35
Anit [1.1K]
\frac{15}{35} /5 \\  \frac{15/5}{35/5}  \\  \frac{3}{7}

That's the simplest form of 15/35. You can use 3/7 to get other equivalent fractions by multiplying the numerator and denominator by the same number. Other examples are 9/21, 6/14, and 12/28.
Hope this helps!

Find the slope of 10y = 7x + 5.<br> Round to the third.
hram777 [196]

Answer:

0.7

Step-by-step explanation:

10y = 7x + 5

Divide both sides by 10.

y = 7x/10 + 5/10

y = 0.7x + 0.5

On a straight line of the form y = kx + m, k is the slope of the line.

In our line, y = 0.7x + 0.5, k is 0.7. Thus, the slope of our function is 0.7

Answer: 0.7
