Answer:

True

Step-by-step explanation:

We need to verify whether 15 and 20 are the correct solution to the rule of "The difference between the 2 number is 5 and the number are in the ratio 3 : 4". Let's see,

First rule → The difference between the 2 numbers is 5

20 - 15 = 5 ⇒ Correct

Second rule → The numbers are in the ratio 3 : 4

15 : 20 ( ÷ 5 to both ratio's ) 3 : 4 ⇒ Correct

Each column of the matrix represents a vertex of a triangle. If Rosa scales the triangle by finding 3T

LiRa [457]

Answer:

$\{(0,0) (0,9) (9,0)\}$

Step-by-step explanation:

Given

See attachment for matrix

From the attachment, we have the following vertices

$(x_1,y_1) = (0,0)$

$(x_2,y_2) = (0,3)$

$(x_3,y_3) = (3,0)$

When scaled by 3T, we have the following:

$(x_1,y_1) =3 * (0,0)$

$(x_1,y_1) =(0,0)$

$(x_2,y_2) = 3 * (0,3)$

$(x_2,y_2) = (0,9)$

$(x_3,y_3) = 3 *(3,0)$

$(x_3,y_3) = (9,0)$

Hence, the vertices are:

$\{(0,0) (0,9) (9,0)\}$

If the zeros of a quadratic function, F, are -2 and 4, what is the equation of the axis of symmetry of F

vagabundo [1.1K]

Answer:

x=1

Step-by-step explanation:

if the zeroes are (-2,0) and (4,0), then the axis of symetry is going to be right in the middle of those two, with the graph reflected equally on either side.

so you get:

(4-2)÷2=1

therefore the equation of the axis of symetry is x=1
