Which translation vector moves every point of a pre-image 4 units left and 6 units up?
F. (4, -6)
G. (-4, 6)
H. (-6, 4)
J. (6, -4)
Answer:
G(-4,6)
Step-by-step explanation:
Here, we want to write a translation
moving left means we are to subtract the number of units from the original
So we have this as -4
Moving up means we are to add the number of units to the original
So we have this as +6 = + 6 units
So the answer here will be;
(-4,6)
G. (-4, 6).
Given translation is 4 units left and 6 units up.
For left we use negative sign. And for up was use plus sign.
So the translation vector is (-4, 6).

Answer:
about 236.715 ft²
Step-by-step explanation:
area of a circle = πr²
so π7.5² = 176.7145868
area of a rectangle is b × h
so 15 × 4 = 60
60 + 176.7145868 = 236.7145868 ft² ≈ 236.715 ft² (for the nearest thousandths)

y – 1.02 = 4.7
solve for y
Answer:
y=5.72
Step-by-step explanation:
Let's solve your equation step-by-step.
y−1.02=4.7
Step 1: Add 1.02 to both sides.
y−1.02+1.02=4.7+1.02
y=5.72
Answer: y=5.72
Step-by-step explanation:
4.7 plus 1.02 equals 5.72
5.72 minus 1.02 equals 4.7

Meagan and jake both live on the same street that the librarian is on.Megan lives 3.5 blicks north of the library,and jake lives 4.5 blocks south of the library.How many blpcks apart do jake and meagan live.
Answer:
8 blocks
Step-by-step explanation:
As the north direction is upwards and the south direction is downwards the total distance between the two people 's (Megan and Jake) houses will be obtained by adding their distances from the library which is in the middle as shown in the diagram.
Hence total distance between the two houses= 3.5 + 4.5= 8 blocks
Jake and Meagan live 8 blocks apart.

3x^2+bx+24=0 if one of its root is 3
Answer:
Other root of equation, [tex]\frac{8}{3}[/tex]
Value of ([tex]b[/tex]), [tex]-17[/tex]
Step-by-step explanation:
The given quadratic equation is in standard form. Standard form is the basic format of representing a quadratic equation, a quadratic equation in standard form would use the following format,
[tex]y=ax^2+bx+c[/tex]
To solve this problem, one could use Vieta's theorems. Vieta's theorems state the following, let ([tex]x_1[/tex]) and ([tex]x_2[/tex]) represent the roots of the equation,
[tex](x_1)+(x_2)=-\frac{b}{a}[/tex]
[tex](x_1)(x_2)=\frac{c}{a}[/tex]
Substitute the given values into the equation,
[tex]3+(x_2)=-\frac{b}{3}[/tex]
[tex](3)(x_2)=\frac{24}{3}[/tex]
Simplify,
[tex](3)+(x_2)=-\frac{b}{3}[/tex]
[tex](3)(x_2)=8[/tex]
Inverse operations,
[tex](3)+(x_2)=-\frac{b}{3}[/tex]
[tex]x_2=\frac{8}{3}[/tex]
Substitute in the value of ([tex]x_2[/tex]),
[tex](3)+(\frac{8}{3})=-\frac{b}{3}[/tex]
Simplify, convert to improper fractions and combine like terms,
[tex]\frac{9}{3}+\frac{8}{3}=-\frac{b}{3}[/tex]
[tex]\frac{17}{3}=-\frac{b}{3}[/tex]
Multiply both sides of the equation by ([tex]3[/tex]) to remove the denominator,
[tex]17=-b[/tex]

If you flip a coin 7 times what is the probability that you will get exactly 2 tails
Answer:
The answer is 2/7.
Step-by-step explanation:
If you flip a coin 7 times then 7 is the denominator, which stands for the total amount of times you flipped the coin. The numerator is 2, which is the amount of times you land on the same thing, in this case, landing on tails.

Find the ratio of the volume of the triangular prism
to the volume of the cuboid,
Give your answer in its simplest form
고
Answer:
The ratio of the volume of the triangular prism to the volume of the cuboid is [tex]\frac{3}{20}[/tex].
Step-by-step explanation:
Geometrically speaking, the volume of the prism is equal to the product of the area of the base and its height. Then, the volumes of the triangular prism and the cuboid are, respectively:
Triangular prism
[tex]V_{tp} = \frac{1}{2}\times 5\,cm \times 4\,cm \times 9\,cm[/tex]
[tex]V_{tp} = 90\,cm^{3}[/tex]
Cuboid
[tex]V_{c} = 6\,cm\times 5\,cm \times 20\,cm[/tex]
[tex]V_{c} = 600\,cm^{3}[/tex]
Lastly, the ratio of the volume of the triangular prism to the volume of the cuboid is:
[tex]r = \frac{V_{tp}}{V_{c}}[/tex]
[tex]r = \frac{3}{20}[/tex]
The ratio of the volume of the triangular prism to the volume of the cuboid is [tex]\frac{3}{20}[/tex].

Answer:
slope = [tex]\frac{4}{5}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 0 ) and (x₂, y₂ ) = (2, 4) ← 2 points on the line
m = [tex]\frac{4-0}{2-(-3)}[/tex] = [tex]\frac{4}{5}[/tex]

1/6
Step-by-step explanation:
Hi! Please explain how you got your answer thanks! :))
Answer:
a + b = 780
Step-by-step explanation:
If we subtract the two equations we can ”eliminate“ a and b and find the value of z.
a-a = 0
b-b = 0
-10z = -700
z = 70
now we have to subistitute this value in the two equations
a + b -4(70) = 500
a + b + 6(70) = 1200
a+b - 280 = 500
a + b + 420 = 1200
If we simplify we have
a + b = 780
a + b = 780

Rosa want to buy a new TV priced at 499.99 The TV is on sale for 15% off but the cashier informs her that if she applies for a store credit card she can have an additional 10% off. How much will Rosa pay after the discounts and 6% tax have been applied? Write and solve an equation to find the final price.
Answer:
$405,44
Step-by-step explanation:
Equation: 499.99 - (499.99 x 15/100) - 1/10[499.99-(499.99 x 15/100)] + 6/100{1/10[499.99-(499.99 x 15/100) = x
Steps: x = (15 x 499.99)/100 = $74.9985
499.99 - 74.9985 = $424,9915
x = (424,9915 x 10)/100 = $42,49915
424,9915 - 42,49915 = $382,49235
x = $22,949541
382,49235 + 22,949541 = $405,441891
That can be rewritten as $405,44.

Find the length of the diagonal of the rectangle. Round your answer to the nearest tenth.
Answer:
d = 15.8 m
Step-by-step explanation:
Apply the Pythagorean Theorem to find the length of the diagonal. The correct equation for this particular rectangle is
d = √(9² + 13²) = √250 = √25·√10 = 5√10
To the nearest tenth, this comes to d = 15.8 m
Answer: 15.8
Step-by-step explanation:
The radius of a circle is 1 yard. What is the circle's circumference?
r=1 yd
Answer:
6.3 yards
Step-by-step explanation:
mathematically, to get the circumference of the circle, we will have to use the formula for the circumference of a circle
we have this as;
C = 2 * pi * r
r is 1 yard
c = 2 * pi * 1 = 2pi yards = 6.3 yards

I don’t know what to do
Answer:
x = 14.4
Step-by-step explanation:
Similar means that the figures are proportional to each other. Because of this, we can form a problem. [tex]\frac{9}{5}[/tex] (the short side lengths) = [tex]\frac{x}{8}[/tex] (the long side lengths). Now we can solve this by cross-multiplying. If we multiply 9 · 8 we get 72, and 5 · x is 5x. 72 = 5x. Now divide both sides by 5. 72 ÷ 5 = 14.4. Therefore, x should be equal to 14.4. Does this make sense?
