Answer: Infinite solutions
Step-by-step explanation:
Solve4x+6y=9for x:
4x+6y=9
4x+6y+−6y=9+−6y(Add -6y to both sides)
4x=−6y+9
4x
/4
=
−6y+9
/4
(Divide both sides by 4)
x=
−3
/2
y+
9
/4
Substitute
−3
/2
y+
9
/4
for x in 12x+18y=27:
12x+18y=27
12(
−3
/2
y+
9
/4
)+18y=27
27=27(Simplify both sides of the equation)
27+−27=27+−27(Add -27 to both sides)
0=0
The <em>correct answer</em> is:
D) If two points lie in a plane, the line containing those points lies in the same plane.
Explanation:
If two planes intersect, they intersect in a line, not a plane.
Space contains at least 4 non-coplanar points, not 3 non-collinear points.
If two lines intersect, their intersection is a point.
Only one line can be drawn through two given points.
7+3x≤8(3+x) perform indicated multiplication on right side
7+3x≤24+8x subtract 8x from both sides
7-5x≤24 subtract 7 from both sides
-5x≤17 divide both sides by -5 (and reverse direction of inequality sign because of multiplication/division by a negative value)
x≥-17/5
x≥ -3.4
105÷35=3. As a result, the unit rate is 3 words per minute. Hope it help!
C squared = a squared+ b squared (formula)
so therefore
(c longest side) (this is your x)
(a and b shorter sides).
C squared = 5 squared + 3 squared
C squared = 25 + 9
C squared = 31
Then you find the square root of c (which is just getting rid of the squared sign) and the square root of 31 And that is your answer
Hope this helps!!
