Which of the following equations has exactly one solution?
Answer:
A and B
Step-by-step explanation:
simplify both sides of the equation
add 4x to both sides subtract 3 from both sides. Divide both sides by 9 and that's it
If the equation given a unique and single value of variable after solving then the equation is said one solution equation.
The equation which has only one solution are,
[tex]5x+3=-2(2x+3)[/tex]
Thus, the option C is the correct option.
How to find one solution of equation?
If the equation given a unique and single value of variable after solving then the equation is said one solution equation.
Such equation gives exactly one solution.
Given information-
To find the equation we have to solve each equation one by one.
A)The equation given in the problem is,[tex]-7x+2&=-3(x-3)-4x-7\\[/tex]
Solve it further,
[tex]-7x+2&=-3x+9-4x-7\\-7x+2&=-7x+2\\.\;\;\;\;\;\;\;\;\;\;\;0=0[/tex]
Thus this equation has no solution. Hence the option A is the incorrect option.
B)The equation given in the problem is,[tex]14x&=7(2x+2)[/tex]
Solve it further,
[tex]14x&=14x+14\\.\;\;\;0=14[/tex]
Thus this equation has no solution. Hence the option B is the incorrect option.
C)The equation given in the problem is,[tex]5x+3=-2(2x+3)[/tex]
Solve it further,
[tex]5x+3=-(4x+6)\\5x+3=-4x-6[/tex]
Bring the same variable terms one side.
[tex]5x+4x=-6-3\\9x=-9\\x=-1[/tex]
As the expression of equation gives the value of variable which is -1.Thus this equation has one solution.
Hence the option C is the correct option.
D)The equation given in the problem is,[tex]3(4x+2)-9=12x-3[/tex]
Solve it further,
[tex]12x+6-9=12x-3\\2x-3=12x-3\\.\;\;\;\;\;\;\;0=0[/tex]
Thus, this equation does not has one solution.
Hence the option D is the incorrect option.
Hence the equation which has only one solution are,
[tex]5x+3=-2(2x+3)[/tex]
Thus, the option C is the correct option.

Lawrence has a paperweight in the shape of a triangular prism. The prism is filled with sand and has a volume of 84 cm3. If the paperweight’s area of the base, B, is 12 cm2, what is the height of the triangular prism?
A. 7 cm
B. 28 cm
C. 24 cm
D. 6 cm
Answer:
H=7cm
Step-by-step explanation:
If volume is: V=B*H then H= V:B
So, you get:
H= 84:12
H=7cm

What is an equation of the line that passes through the points (0, 3) and (5, -3)?
Answer:
y = -6/5x + 3
Step-by-step explanation:
y2 - y1 / x2 - x1
-3 - 3/ 5 - 0
= -6/5
To find the y-intercept, you need to plug the coordinates into the equation,
y = -6/5x + b
3 = -6/5(0) + b
3 = 0 + b
b = 3
The equation is y = -6/5x + 3

Give me the answer for the blanks
Airplane
Boat
Bike
The clues are at true bottom
Answer:
Airplane goes 550 mph
Bike goes 9 mph
Ship goes 27 mph
Step-by-step explanation:
The airplane goes 1,925 every 3.5 hours
Divide 1925 by 3.5
1925/3.5 = 550mph
Do the same thing with the bike’s numbers:
45/5 = 9
So 9mph
And again with the ship:
432/16 = 27
It also says its three times as fast as the bike so:
9 x 3 = 27
So the ship goes 27 mph

Can you help me match each figure with the appropriate angle pair relationship
Answer:
co interior angle plz take my and
Answer:
1) Alternate exterior
2) alternate interior
3) consecutive interior angles
Alright so here’s a trick
Alternate already means different sides so look for that.
Interior angles are all the angles inside the two parllel lines.
Exterior angles are all angles out side the two parralel lines.
No matter what if its alternative interior or exterior, it should make a perfect
“/“ or back slash.
Consecutive is on the same side.
Corresponing is also on the same side but it has 1 exterior and 1 interior
