(a) Reflect the point (7, -9) across the y-axis:
(b) Reflect the point (7, -9) across the x-axis:
Answer:
(-7,-9) and (7,9)
Step-by-step explanation:7,-9 so we do across the x so you need a graph for this now x goes left so we plot the coordinates in the third box 7,-9 is in the 4 box so after we plotted that you can see it reflects.Now y coordinate since the y line goes up we plot the coordinates on top of the 4 box where our original coordinates stay now it should be 7,9 the y becomes positive which is 9.

Answer:

Step-by-step explanation:
2y=12
Divide each term by
2
and simplify.
y
=
6
Answer:
x = -2 and y = 3
Step-by-step explanation:
plug in the x = 3y - 8 into the x for the top equation
so it looks like this...
-3(2y - 8) + 2y = 12
solve
-6y + 24 + 2y = 12
-4y + 24 = 12
-24 -24
-4y = -12
divide bye -4
y = 3
plug in y = 3 on the second equation
x = 2y - 8
x = 2(3) - 8
x = 6 - 8
x = -2
The graph shows the relationship between the radius and volume for many cones whose height is 6 inches. Select ALL true statements about such cones.
Answer:
E. If the radius of the cone is 2 inches, the volume of the cone is 25 cubic inches.
B. The relationship between radius and volume is not linear.
Step-by-step explanation:
The true statement regarding the cones should be
If the radius of the cone is 2 inches, the volume of the cone is about 25 cubic inches.
The relationship between radius and volume is not linear.
What is the volume of cone?
The volume of the cone should be equivalent to one-third of the volume of the cylinder that contains a similar radius of the base and height. Here V means the volume, r means the radius and h means the height.
According to the graph, we can say that in the case when the radius should be 2 inches so the volume should be 25 cubic inches. And, the relation between the radius and the volume should not be linear.

Step-by-step explanation:
A shop sells packs of black pens, packs of red pens and packs of green pens.
There are
2 pens in each pack of black pens
5 pens in each pack of red pens
6 pens in each pack of green pens
On Monday, the ratio of number of packs of pens sold was Black : Red : Green = 7 : 3 : 4
A total of 212 pens were sold.
Work out the number of green pens sold.
Answer:
The number of green pens sold are 96 green pens
Step-by-step explanation:
The given parameters for the packs of pens sold by the shop are;
The number of pens in each pack of black pens = 2 pens
The number of pens in each pack of red pens = 5 pens
The number of pens in each pack of green pens = 6 pens
The ratio of number of packs of pens sold Black : Red : Green = 7 : 3 : 4
The total number of pens sold = 212
Let 'x' represent the number of packs of pens sold
Therefore, the fraction of the packs the pens sold that are black pens = 7/(7 + 3 + 4) = 7/14 = 1/2
∴ 1/2 of the number of packs of pen sold = packs black pens = x/2
The fraction of the packs the pens sold that are red pens = 3/14
∴ 3/14 of the number of packs of pen sold = packs of red pens = 3·x/14
Similarly, we have;
The fraction of the packs the pens sold that are green pens = 4/14 = 2/7
∴ 2/7 of the number of packs of pen sold = packs of green pens = 2·x/7
Therefore, we have;
x/2 × 2 + 3·x/14 × 5 + 2·x/7 × 6 = 212
Where;
x/2 × 2 = The number of black pens sold
3·x/14 × 5 = The number of red pens sold
2·x/7 × 6 = The number of green pens sold
∴ 53·x/14 = 212
x = 212 × 14/53 = 56
∴ The number of packs of pens sold = x = 56 packs
The number of green pens sold = 2·x/7 × 6 = 2 × 56/7 × 6 = 96
The number of green pens sold = 96 pens.

4. Answer the question below using complete sentences. * Rae made a table of x and y values. The relationship between the x and the y values in Rae's table is not a function. One of the values of x is missing from Rae's table, as shown. What is a value of x that Rae could use to complete her table to show that the relationship between x and y is not a function? explain your answer
Answer:
Any of x = {-3, 5, -1, 0}Step-by-step explanation:
Since the relationship in the table is not a function, Rae could put any values for x that is already in the table.
x = -3, 5, -1, 0This will result in repeat of x-values with different corresponding y-values.

luca sells muffins and juice boxes. muffins are $1.50 each and jucie boxes are $1.25 each. write an algebraic expression for the total income luca received from the sale of muffins and juice boxes
Answer:
1.5m+1.25j
Step-by-step explanation:
m equals the number of muffins sold, and because each muffin sells for $1.50, 1.5m represents the income made from the muffins.
Same thing with the juice boxes, j equals the number of juice boxes sold, and because each juice box sells for $1.25, 1.25j represents the income made from the juice boxes.
Add the income from both of them to get the total income, and you get 1.5m+1.25j.

I need help on my warm up!! pls thx!
Step-by-step explanation:
[tex] \tt{30.16 = 17.56 + 5x} [/tex]
Swap the sides of the equation :
⤑ [tex] \tt{17.56 + 5x = 30.16}[/tex]
We want to remove the 17.56 first.
Since the original equation is 17.56 , we are going to use the opposite operation and subtract 17.56 from both sides :
⤑ [tex] \tt{5x + 17.56 - 17.56 = 30.16 - 17.56}[/tex]
Simplify. 17.56 - 17.56 = 0 on the left. 30.16 - 17.36 = 12.6 on the right.
⤑ [tex] \tt{5x = 12.6}[/tex]
Then, we need to think about how to remove the coefficient 5. Since the opposite of multiplication is division , I am going to divide both sides by 5.
⤑ [tex] \tt{ \frac{5x}{5} = \frac{12.6}{5}} [/tex]
Simplify. 5/5 = 1 on the left and 12.6/5 = 2.52 on the right. So, Our answer is x = 2.52.
[tex] \pink{ \boxed{ \boxed { \tt{Our \: final \: answer : \underline{ \underline{ \bold{ \tt{x = 2.52}}}}}}}}[/tex]

2x^2+2x is it simplified
Answer:
Yes it is simplified
Step-by-step explanation:
2x^2 is not a like term to 2x because 2x does not have an exponent. Therefore, you cannot add 2x to 2x^2. So it is as simplified as it can be at this point

Marissa climbs a vertical ladder to go down a slide. The slide makes a 25° angle with
the ground. If the ladder is 12 ft tall, what is the length of the slide?
Answer:
28.39 ftStep-by-step explanation:
The ladder is the vertical leg and the slide is the hypotenuse of the triangle formed.
The angle opposite the ladder is 25°, slide has the length of x.
sin 25° = opposite/hypotenusesin 25° = 12/xx = 12/sin 25°x = 28.39 ft
