Answer:
The scale factor SF = [tex]\frac{7}{3}[/tex] ⇒ C
Step-by-step explanation:
If the point (x, y) dilated by a scale factor n, then the coordinates of its image are (n x, n y)
Let us solve the question
∵ The coordinates of the point K are (-3, 6)
∴ x = -3 and y = 6
∵ The coordinates of its image k' are (-7, 14)
→ From the rule above the image is (n x, n y)
∵ The scale factor is n
∴ n x = -7
∴ n y = 14
→ Substitute x by -3
∵ n (-3) = -7
∴ -3n = -7
→ Divide both sides by -3
∵ [tex]\frac{-3n}{-3}[/tex] = [tex]\frac{-7}{-3}[/tex]
∴ n = [tex]\frac{7}{3}[/tex]
→ Substitute y by 6
∵ n (6) = 14
∴ 6n = 14
→ Divide both sides by 6
∵ [tex]\frac{6n}{6}[/tex] = [tex]\frac{14}{6}[/tex]
∴ n = [tex]\frac{7}{3}[/tex]
→ Both coordinates gave the same value of n
∴ The scale factor SF = [tex]\frac{7}{3}[/tex]
How can you get equation b from equation A. 3(x+2)=18 B. X+2=18
Answer:
We start with the equation:
A: 3*(x + 2) = 18
And we want to construct equation B:
B: X + 2 = 18
where I suppose that X is different than x.
Because in both equations the right side is the same thing, then the left side also should be the same thing, this means that:
3*(x + 2) = X + 2
Now we can isolate the variable x.
(x + 2) = (X + 2)/3
x = (X + 2)/3 - 2
Then we need to replace x by (X + 2)/3 - 2 in equation A, and we will get equation B.
Let's do it:
A: 3*(x + 2) = 18
Now we can replace x by = (X + 2)/3 - 2
3*( (X + 2)/3 - 2 + 2) = 18
3*( (X + 2)/3 ) = 18
3*(X + 2)/3 = 18
(X + 2) = 18
Which is equation B.
write an equation from the table.

Answer:
y=-2x+7
Step-by-step explanation:
slope intercept form: y=mx+b
Slope formula: [tex]\frac{rise}{run}[/tex] or [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{2}}[/tex]
You can pick any two equations. In this example, I chose the firsts 2.
(0,-7) and (1,-9)
Plug into the slope formula,
-9+7 over 1-0 which is -2/1 or -2
The m in y=mx+b is the slope, the equation above is the sloe formula meaning -2 is the slope. The b is the y, when it is at 0. The y at 0 for this equation is -7. Thus, when plugging in the equation, y=-2x-7

Q.4. The HCF and LCM of two numbers are 12 and 24 respectively. Find the product of the two numbers.
Answer:
288
Step-by-step explanation:
Since, the product of the HCF and LCM of two numbers is equal to the product of the two numbers.
Therefore,
The product of the two numbers
[tex] = HCF \times LCM \\ \\ = 12 \times 24 \\ \\ = 288[/tex]

Tony uses 4 cups of shredded cheese on 3 pizzas. How many cups of cheese are on each pizza? Answer in fraction form.
Answer:
1 1/3
Step-by-step explanation:
Answer:
4/3 (improper form) 1 1/3 (mixed form)
Step-by-step explanation:
Put the amount over whatever it's being divided amongst. In this case, you're dividing 4 cups by 3 pizzas. Fractions are actually just the top being divided by the bottom, so just think of it that way.

Verify the identity. & Show your work.
cos (x - y) - cos (x + y) = 2 sin x sin y
Answer:
this is a required answer.
Answer:
See Below.
Step-by-step explanation:
We want to verify:
[tex]\cos(x-y)-\cos(x+y)=2\sin(x)\sin(y)[/tex]
We will utilize the following identities:
[tex]\cos(x-y)=\cos(x)\cos(y)+\sin(x)\sin(y)[/tex]
And:
[tex]\cos(x+y)=\cos(x)\cos(y)-\sin(x)\sin(y)[/tex]
So, by substitution, we acquire:
[tex](\cos(x)\cos(y)+\sin(x)\sin(y))-(\cos(x)\cos(y)-\sin(x)\sin(y))=2\sin(x)\sin(y)[/tex]
Distribute:
[tex]\cos(x)\cos(y)+\sin(x)\sin(y)-\cos(x)\cos(y)+\sin(x)\sin(y)=2\sin(x)\sin(y)[/tex]
The first and third term will cancel:
[tex]\sin(x)\sin(y)+\sin(x)\sin(y)=2\sin(x)\sin(y)[/tex]
Combine like terms:
[tex]2\sin(x)\sin(y)\stackrel{\checkmark}{=}2\sin(x)\sin(y)[/tex]

A cereal box has a length of 8 inches, a width of1 - inches, and a height of 12 - inches. What is thevolume of the cereal box?
Answer:
96
Step-by-step explanation:
LxWxH=V or BxH=V
L=8
W=1
H=12
8x1x12=96
Answer: 96in²
Step-by-step explanation: To find the volume, you multiply the Length, Width, and Height.
The formula is whl, which means W × H × L.
So, we'll multiply 8 by 1 by 12.
Step 1.
Multiply 8 by 1.
8 × 1 = 8
Step 2.
Multiply 8 by 12.
8 × 12 = 96
Hence, 96in² is the answer.
A box is a cuboid with dimensions 29cm by 15cm by 20cm all measured to the nearest centimetre.? disc cases are cuboids measured 1.4cm by 14.2 by 19.3 to t he nearest millimetre. show that 19 disc cases stacked straight down will definitely fit in the box
Answer:
See explanation.
Step-by-step explanation:
The question requires you to determine the volume of both the box and the disc case then find how many of the disc cases can fit in to the box.
The volume of the box
V= l*w*h
V= 29 * 15 * 20 = 8700 cm³
The volume of the disc case
V=l*w*h
V=1.4 * 14.2*19.3
V=383.684 cm³
The number of disc cases that fit in the box will be;
8700/383.684
22.67
In this calculation, it is clear that 19 of these disc cases will definitely in the box because the box can accommodate 22 of these disc cases.

the area of a right triangle is 336 square centimeters. The base of the right triangle is 48 centimeters. What is the length of the hypotenuse of the right triangle?
Answer:
50 cm
Step-by-step explanation:
So the first step is to find the height, and to do that you know that the area of a triangle is height * base / 2 = area. Plugging in the numbers you have, you get:
[tex]height*48/2=336[/tex]
Then, this becomes
[tex]height * 24 = 336[/tex]
Divide both sides by 24
[tex]height = 14[/tex]
Now you can use the base and the height to find the hypotenuse using the Pythagorean Theorem: [tex]a^{2} +b^{2} =c^{2}[/tex]
[tex]48^{2} +14^{2} =c^{2} \\2304 + 196 = c^{2}\\2500 = c^2\\50 = c\\c = 50[/tex]
Therefore the length of the hypotenuse is 50 cm

Every kid in Mr. Levans's 3rd grade class made a valentine for every kid in the class, including themselves. If the class made a total of $484$ valentines, how many kids are in the class?
Pls tell me and why it is correct I will mark you brainliest!! (20 POINTS!!)
Answer:
22
Step-by-step explanation:
So the number of valentines made is going to equal the number of kids * the number of kids, so all you have to do is the square root of 484.
This is 22, because 22 * 22 = 484.
