ANSWER

B. a reflection across the x-axis

EXPLANATION

The given triangle has vertices

A(-2,3)

B(3,4)

C(1,-2)

The image triangle has vertices

P(-2,-3)

Q(3,-4)

R(1,2)

We can see that the mapping for the above transformation is

$(x,y)\to (x,-y)$

This is the mapping for reflection across the x-axis.

The correct choice is B.

Compare the functions.

Function h has the largest y-intercept which is 44

Step-by-step explanation:

Any linear function is represented in the form

$f(x) = mx+b$

Here b is the y-intercept of the linear function i.e. the constant term in the function.

We will compare all the functions with the general form we get

y-intercept of f(x) = 1

y-intercept of g(x) = 8

y-intercept of h(x) = 44

y-intercept of j(x) = 0

Hence,

Function h has the largest y-intercept which is 44

Find the value of y if VP is an angel bisector, m<2=1+28y and m

galben [10]

Answer:

$\boxed{y=1}$

Step-by-step explanation:

Since $m\angle1=m\angle2$ due to $\over{VP}$ is an angle bisector, we have the following:

$m\angle1+m\angle2=m\angle XVW\\(1+28y)+(1+28y)=59y-1\\2+56y=59y-1\\2+1=59y-56y\\3=3y\\y=1$

Sum of three numbers in an as is 33 and the sum of thier cubes is 5049.find the numbers

Alex73 [517]

Sum of three numbers is 33 and sum of their cubes is 5049 then three numbers are 7,11,15 or 15,11,7.

As given,

Let a-d, a, a +d be three numbers

Sum =33

⇒a-d + a +a +d =33

⇒ a =11

Sum of cubes= 5049

⇒ (a-d)³ + a +(a +d)³ =5049

⇒ a³ -d³ -3a²d +3ad² + a³ +a³ +d³ +3a²d +3ad² =5049

⇒3a³ + 6ad² = 5049

⇒ d=± 4

Therefore, sum of three numbers is 33 and sum of their cubes is 5049 then three numbers are 7,11,15 or 15,11,7.
