What is the image of point A(1, 3) after a dilation with a scale factor of -4

Answer:

I think its 66 but i dont know. i took the test and had the same question but teachers are different

Step-by-step explanation:

Answer:

33 deg

Step-by-step explanation:

Since <POQ is a right angle, lines MQ and PO are perpendicular. That makes <PON a right angle with measure 90 deg.

m<MOP + m<MON = m<PON

3x - 3 + 4x + 9 = 90

7x + 6 = 90

7x = 84

x = 12

m<MOP = 3x - 3 = 3(12) - 3 = 36 - 3 = 33

m<MOP = 33

Answer:

the answer is -4

Step-by-step explanation:

step 1: -7m<28

step 2: -7m÷ (-7)>28÷(-7)

step 3: m>28÷(-7)

step 4: m>-28÷7

step 5: m>-4

Answer:

Step-by-step explanation:

Answer:

B: 11

Step-by-step explanation:

121 is the area. Since a square is a shape with all even sides you need to find one number that multiplies by itself to get 121. 11x11=121

B: 11

Answer:

B is a solution, A and C are not

Step-by-step explanation:

Answer: (1,5) = No

(0,7) = yes

(-3,-6) no

Step-by-step explanation:

(1,5) is outside the double shaded region and (-3,-6) is on the dash lined therefore its ruled outside as well

Answer:

The volume of the olive oil is 661.4583 cm³

Step-by-step explanation:

The rule of the density of an object is d = M ÷ V, where

∵ A bottle is filled with 635 g of olive oil

∴ M = 635 g

∵ The olive oil has a density of 0.96 g/cm³

∴ d = 0.96 g/cm³

→ Substitute them in the rule above

∵ 0.96 = 653 ÷ V

→ Multiply both sides by V

∴ 0.96 V = 635

→ Divide both sides by 0.96

∴ V = 661.4583 cm³

∴ The volume of the olive oil is 661.4583 cm³

Answer:

D. [tex] \frac{1}{4} [/tex]

Step-by-step explanation:

Given that rectangle V'W'X'Y' is a dilation of rectangle VWXY, this means that the dimensions of rectangle VWXY was reduced by to get the dimensions of V'W'X'Y'.

Therefore, the ratio of any segment of V'W'X'Y', to a corresponding segment of VWXY would be equal to the scale factor.

W'X' = 5

WX = 20

Therefore:

Scale factor = [tex] \frac{5}{20} = \frac{1}{4} [/tex].

A scale factor that is a fraction tells us that the original figure reduced in size resulting into another new figure whose sides are of proportional lengths to the original figure.

In other words, the original figure was compressed go form a new figure.

Step-by-step explanation:

When Betty used 1/2 OF the 1/3 yards she has she has to multiple those. It's easier to put it in a sentence in my opinion because then you can see the "of" in the sentence which means to multiply. Hope this helps!

Answer:

(5, 9 )

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y ) → (- x, y ), thus

(- 5, 9 ) → (5, 9 )

Answer: 36 games

Step-by-step explanation:

75% is 3/4

1/4 of 48 is 12, thus 3/4 of 48 is 36

Therefore, the baseball team won 36 games

Answer:

A

Step-by-step explanation:

Let T represent the total number of turtle nests found during the season.

The 28 turtle nests was 40% of 0.4 of the total. Therefore:

[tex]28=0.4T[/tex]

So, to find T, divide both sides by 0.4:

[tex]T=70[/tex]

So, the total number of turtle nests the group found during tthe season was 70.

Hence, our answer is A.

Answer:

-5

Step-by-step explanation:

[tex]f(x) = - 5 \\ \\ plug \: x = - 4 \\ \\ f( - 4) = - 5[/tex]

Since it is constant function so the value will remain unchanged.

Answer:

(-1,4)

Step-by-step explanation:

First lets put the two equations into y=mx+b format by subtracting 2x and 4x to the right side of their equations.

y=-2x+2

y=-4x+0

Now you can put this into a system of equations, but you can also plug in the coordinates to see if both equations are equal. I will show system of equations solution.

-2x+2=-4x, solve this by adding -2x to the right side so that the 2 is by itself.

Now you have 2=-2x. Divide by -2 to get the x by itself, now you have x=-1. Plug this back into one of the equations, so y=-4x would be y=-4(-1), so y=4.

Answer:

-1,4

Answer:

The domain is (-∞ , -3) ∪ (-3, ∞) ⇒ D

Step-by-step explanation:

The domain of the rational fraction is the values of x which make the fraction defined. That means the domain does not contain the values of x which make the denominator equal to 0.

∵ g(x) = [tex]\frac{1}{x+3}[/tex]

∴ The denominator = x + 3

→ Equate the denominator by 0

∵ x + 3 = 0

→ Subtract 3 from both sides

∴ x + 3 - 3 = 0 - 3

∴ x = -3

→ That means the domain can not have -3 because it makes the denominator

   equal to 0

∴ The domain is all values of real numbers except x = -3

∴ The domain = {x : x ∈ R, x ≠ -3}

∴ The domain = (-∞ , -3) ∪ (-3, ∞)

Answer:

(2, 5), (-5, 6) and (-1, 1)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.

If a point A(x,y) is translated a units right and b units up, the new location is at A'(x + a, y + b).

From the image attached, the location of the vertices of the triangle is at (0,2), (-7, 3) and (-3, -2). If the triangle is under the translation (x, y) ⇒ (x + 2, y + 3), the new location of the vertices would be at (2, 5), (-5, 6) and (-1, 1)

Answer

85%

Step-by-step explanation:

34/40=0.85

Answer:

85%

Step-by-step explanation:

Easy way to solve this is just to divide 34 and 40.

34÷40=0.85.

Then you multiply 0.85 by 100 to get the decimal to the front.

0.85 x 100=85
