How do I solve this equation and check all the solutions?
Answer:
x = 12
Step-by-step explanation:
[tex]\sqrt{3x}[/tex] + 10 = x + 4
[tex]\sqrt{3x}[/tex] = x - 6
( [tex]\sqrt{3x}[/tex] )² = ( x - 6 )²
3x = x² - 12x + 36
x² - 15x + 36 = 0
(x - 3)(x - 12) = 0
[tex]x_{1}[/tex] = 3
[tex]x_{2}[/tex] = 12
Check the answer:
[tex]\sqrt{3*3}[/tex] + 10 ≠ 3 + 4
13 ≠ 7 ⇒ 3 is not the root of original equation (strange root)
[tex]\sqrt{3*12}[/tex] + 10 = 12 + 4
16 = 16 ⇒ 12 is the root of original equation
How do I solve this equation and check all the solutions?
Answer:
10
Step-by-step explanation:
x-√2x-5=5
-√2x-5=5-x
√2x-5=-5+x
2x-5=x²-10x+25
2x-5-x²+10x-25=0
12x-20-x²=0
-x²+12x-20=0
x²-12x+20=0
x=10
Note: there is a another answer x=2 but the equality will be false if x=2 so the answer is 10

translate FGH 3 units down and 2 units left followed by a rotation counterclockwise 90°.Then followed by a dilation by a scale factor of 2.
Step-by-step explanation:
Hope this helps, happy learning!!!
The diagram of translatation FGH 3 units down and 2 units left followed by a rotation counterclockwise 90° is attached below.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form.
Depending on the scale factor, the object's size can be raised or lowered.
The translate FGH 3 units down and 2 units left followed by a rotation counterclockwise 90°.Then followed by a dilation by a scale factor of 2.
F ( -1, 0)
G (1, 0)
H ( -1, 1)
Thus, counterclockwise 90°
F' ( 0, 1)
G' (0, -1)
H' ( -1, -1)
Scale factor = 2
Then
F'' ( 0, 2)
G'' (0, -2)
H'' ( -2, -2)

Multiple Choice An equation of the line
whose slope is 3 and whose y-intercept is 8 is
? ?
A y = 8x + 3
C y = – 3x + 8
Ey = 3x - 8
B y = 3x + 8
D y = - 3x – 8
Answer:
y = 3x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3 and c = 8 , thus
y = 3x + 8 ← equation of line
Harper needs to buy some new leotards for gymnastics practice. At the sporting goods store, she finds 2 leotards on sale for $24.80 each. She buys them both and finds out that she saved a total of $22.38. If she saved the same amount on each one, what was the original price of each leotard?

The trend line passes through points (2,5) and (6,11). What is the slope of the trend line?
What is the y-intercept of the trend line?
Y=___X +___
Answer:
slope = 3/2
y intercept = 2
y = 3/2x + 2
Step-by-step explanation:
to find the slope you will you (y₂-y₁) ÷ (x₂-x₁)
(11-5) ÷ (6-2) =
6 ÷ 4 = 3/2
slope = 3/2
to find the y intercept you with use the slope intercept formula (y = mx+ b) and use one point given for x and y
for the example im going to use the point (2,5)
5 = 3/2 (2) + b
5 = 3 + b
subtract three from both sides to find b (y-intercept)
b = 2

After restocking the vending machine, Sonya determined that 2 packs of mints were sold for every 6 packs of gum. If a total of 160 packs of candy were sold, how many were packs of gum?
Answer:
80
Step-by-step explanation:
160÷2=80 yay!!!!!!!!!!!
Answer:
(By mints I hoped you meant candy) 480 packs of gum
Step-by-step explanation:
2 packs of candy for every 6 packs of gum. Divided beach side by two to get ration of 1:3. This means that for every 1 pack of candy 3 packs of gum are sold. 160 x 3 = 480.
On a coordinate plane, which axis is the horizontal axis, and which is the vertical axis? Is there a way to graph points that are not whole numbers? How do you think you can do that? Describe some real-world situations that remind you of the coordinate plane.
Answer:
Horizontal axis is X
Vertical Axis is Y
You can graph points that are not whole numbers, you just have to add more lines or estimate where the point may be
Battleship maybe? Or like the longitude and latitude on a map?

How many months does it take to earn $180 in interest on an investment of the principal is $5000 and the interest rate is 2%?
Answer:
months = 6.67
Step-by-step explanation:
time in years = interest / (principal amount x rate)
time in y = 180 / (5000 x 0.02)
time in y = 180 / 100
time in months = 12 / 1.8

Train A leaves a station 45 minutes before train B. Both trains travel in the same direction and their speeds are 36km/h and 48km/h respectively.
i) How long will it take train B to catch up with train A? ii) How far from the start were the two trains when they met
Answer:
Train B catches up with train A at 2.25 h
The two trains meet at 108 Km from the start
Step-by-step explanation:
Relative Speed
There are two trains, A and B leaving the same station. Train A leaves 45 minutes before train B at va=36 Km/h. Train B travels at vb=48 Km/h in the same direction, so they eventually meet.
i)
Calculate the head start of train A Xh, i.e. the distance it traveled in 45 minutes = 45/60=0.75 h.
[tex]X_h=36*0.75=27~Km[/tex]
When train A is 27 Km ahead, train B leaves the station. The relative speed between them is vb-ba=48 - 36 = 12 Km/h.
Thus, for train B to meet with train A, the head start must be traveled at the relative speed.
The time needed to do that is:
[tex]\displaystyle t=\frac{27~Km}{12~Km/h}[/tex]
t = 2.25 h
Train B catches up with train A at 2.25 h
ii) In the time calculated above, train B has traveled a distance of:
[tex]X_b=48~Km/h*2.25~h=108~Km[/tex]
The two trains meet at 108 Km from the start

Which set of ordered pairs represents y as a function of x?

{(3, 3), (3, 4), (4, 3), (4, 4)}
{(1, -5), (1, 5), (2, -10), (2, -15)}
Answer:
{(2,-1), (4, -2), (6, -3), (8, -4)}
Step-by-step explanation:
The other ordered pairs have a common domain value which means they are not a function.
For example:
{(5,7), (5,8), (10,3)} would not be a function because the 5 is repeating
However
{(2,6), (4,6), (22,7)} would be function because there are no numbers in the x part of the ordered pair that repeat. (x,y)

Step-by-step explanation:
It goes up by 3 units and goes to the left by 2, 3/2. And the line intercepts the axis at -1.
How many solutions does this equation have?
-4 + 19 - 7f = -15 - 7f
no solution
one solution
infinitely many solutions
Answer:
No solution
Explanation:
-4+19-7f = -15-7
cancel terms on both sides ( add 7f on both sides)
Calculate the sum
-4+19= -15
-4+19=15
15 = -15
The statement 15 = -15 is false so there is no solution :)
