Answer:
y=7
Step-by-step explanation:
We have two numbers,
x
,
y
. We know two things about them:
2
x
+
y
=
25
3
x
−
y
=
20
Let's add these two equations together which will cancel the
y
:
5
x
+
0
y
=
45
x
=
45
5
=
9
We can now substitute in the
x
value into one of the original equations (I'll do both) to get to
y
:
2
x
+
y
=
25
2
(
9
)
+
y
=

y
=

y
=

What is the image point of (-6,9)(−6,9) after a translation left 4 units and down 1 unit?
Answer:
( -10,8)
Step-by-step explanation:
(-6,9)
Shifting 4 units left means subtract 4 from the x coordinate
(-6-4,9)
Shifting 1 unit down means subtract 1 from the y coordiant
(-6-4,9-1)
( -10,8)
Answer:
(-10, 8)
Step-by-step explanation:
A translation left 4 units and down 1 unit would be described algebraically as:
[tex](x,y)\rightarrow(x-4,y-1)[/tex]
Apply rule to (-6,9):
[tex](-6,9)\rightarrow(-6-4,9-1)\rightarrow(-10,8)[/tex]
The image after the translation should be (-10, 8).
Hope this helps.

Nicholas's sand castle is 30 cm tall and he is adding sand at a rate of 12 cm per minute. Nina's sand castle is 78 cm tall and she is adding more sand to it at a rate of 6 cm per minute. After how many minutes, x, will Nina and Nicholas's sand castles be the same height?
Answer:
8 minutes
Step-by-step explanation:
Speed or Rate = Distance / time
Distance = Speed × time
Nicholas's sand castle is 30 cm tall and he is adding sand at a rate of 12 cm per minute.
Nicholas = Nina
30cm + (12cm/min)x
= 30 + 12x
Nina's sand castle is 78 cm tall and she is adding more sand to it at a rate of 6 cm per minute.
78cm + (6cm/min)x
78 + 6x
30 + 12x = 78 + 6x
12x - 6x = 78 - 30
6x = 48
x = 48/6
x = 8 minutes
Therefore, after 8 minutes, Nina and Nicholas's sand castles be the same height.
Which of these is NOT a function ?
Answer:
A
Step-by-step explanation:
it fails the vertical line test
Answer: A
Step-by-step explanation: The easiest way to determine
if a relation is a function is to use the vertical line test.
The vertical line test tells us that if we can draw a vertical line
that intersects more than one point on the graph of a relation,
then the relation is not a function.
In this case, the only graph that is not a function is A.
If we draw a vertical line on the graph, it's possible that
the lie will hit two points on the graph telling us that it's not a function.

81 Degrees/Base Angle
Step-by-step explanation:
x+x+18=180 1. Add x+x= 2x. 2. Subtract 18 from each side, which leaves you with 2x=162. 3. Divide each side by 2, that gives you a final answer of x=81
If you bought a stock last year for a price of $90, and it has gone down 13% since then, how much is the stock worth now, to the nearest cent?
Answer:
It is now $109.62. You would multiply .13 (13%) by 126 which would give you 16.38. You would then subtract 126-16.38 to get 109.62.
Hope this helps, have a great day, have a wonderful weekend and stay safe!
Also Happy Halloween! :) :D :3
Answer:
$78.30
Step-by-step explanation:
13% of 90 is 11.7, 90 - 11.7 = 78.3, therefore our answer is $78.30

Answer:
Step-by-step explanation:
Okay Im going off of my work because we did some in class and then the rest by ourselves but i turned mine in yesterday but didnt recieve a grade yet but i hope these help you...
The number number line it is seven units apart.
The absolute value larger number smaller number would be 2 - (-5). So what you do with that is keep the 2 change the subtraction sign to plus sign and change the negative 5 to positive 5. So your answer would be 7.
And smaller number to larger number would be -5 - 2. And then you do the same steps as the last one. Keep the negative five, change the subtraction sign to addition sign and make the two negative. And that answer would be -7
2. For the number two problem you would plot the robins nest just below the top of the verticle line. the red squirrel den would be right next to the zero but a tad up. And the groundhog burrow would be below the zero mark and a little before the end of the verticle line.
Next, for groundhog burrow to red squirrel den you put the number 0.3-(-1.2)=1.5 Red squirrel den to Robin’s nest 3.6 – 0.3 = 3.3. And for the last one Groundhog burrow to Robin’s nest 3.6 – (-1.2) = 4.8.
3. you have to turn the 1 1/2 and 3/4 into 8ths. 1/2= 3*4 = 12 and for the denominator 2*4 = 8. So 12/8.
The next one is 3*2 which is 6 and 4*2=8
so now you have 12/8, 6/8, and 1/8
you have to add the points on the chart (i cant really help you on this part because i do not know how to upload picture) but you would make 24 and then you find where 12/8 would go and draw the hops but on mine the hop looks like how you would draw a rainbow but just one for the 12. Then do the same for the 6 and add 1 for the last one to make 19.
On mine I add the 12 + 6 + 1 = 19 so that is how i got mine. (sry if this a bad explination)
it should kinda look like this on the chart.
| | | | | | | | | | | | | | | | | | | | | | | | they should be spaced apart like this.
and for the last one i put cup 3 because it bigger than the amount of ingrident in the recipe. (im not sure if that one was the answer this is the only part we didnt get help on in class)
Step-by-step explanation:
Method B
(Step 1) | 19 - (-12) |
(Step 2) | 19 + 12|
(Step 3) | 31 | = 31

Two equal forces, the magnitude of each of them is 6 N. , the magnitude of
their resultant is 6 N. , then the angle between them equals
Answer:
The angle between both forces is equal to 120°.
Step-by-step explanation:
Net Force
The net force between two or more forces is determined by adding their vector representation.
We have two forces of 6 N each but applied to an object at different angles. The resulting force should be of magnitude 6 N, as required by the question.
Please refer to the image where both forces F are applied at an angle θ with respect to the vertical. For the total force to have a magnitude of F, the vertical component of one of them must be F/2 as shown in the diagram.
The angle formed by this configuration must comply with the trigonometric ratios in the rectangle triangle.
[tex]\displaystyle \cos\theta=\frac{F/2}{F}=\frac{1}{2}[/tex]
The angle is θ = 60° which makes the angle between both forces be equal to 120°.

the graphs of f(x) and g(x)= f(x)+k are shown below. the value of k is ____
Answer:
The value of k is 2
Step-by-step explanation:
The rule of vertical translation
If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k ⇒ add y-coordinate of every point by kIf the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k ⇒ subtract y-coordinate of every point by kFrom the graph
∵ Point (0, 0) ∈ f(x)
∵ Point (0, 2) ∈ g(x)
∵ Point (2, 4) ∈ f(x)
∵ Point (2, 6) ∈ g(x)
∴ Each y-coordinates of the points on f(x) added by 2 on g(x)
→ That means f(x) is translated up 2 units
∴ f(x) is translated up by 2 units
→ By using the first rule above
∴ g(x) = f(x) + 2
∵ g(x) = f(x) + k
∴ k = 2
∴ The value of k is 2
Leah wants to divide x by -2.4. What number should she multiply by x to find
the answer?
The number which is to be multiplied with x to find the answer will be equal to [tex]\frac{-1}{2.4}[/tex] .
What do you mean by algebraic expressions ?
Algebraic expression is an equation which consists of variables and the arithmetic operations such as division , multiplication , etc.
It is given that Leah wants to divide x by a number which is -24. We know that an algebraic expression need a variable.
x divided by -2.4 can be written as :
= x ÷ -2.4
In fractional division, we need to find the reciprocal of the divisor fraction and then multiply it with the dividend to find the solution.
The expression can be written as :
= x × [tex]\frac{-1}{2.4}[/tex]
or
We need to multiply [tex]\frac{-1}{2.4}[/tex] by x to find the answer.
Therefore , the number which is to be multiplied with x to find the answer will be equal to [tex]\frac{-1}{2.4}[/tex] .
