mutiplying -1.24 by 4.25 would get you -5.27

SSSSS [86.1K]

PEMDAS states that the value in the parenthesis should be evaluated first:
4(5*6)
4(30)
After just multiply the value in the parenthesis by the number outside of the parenthesis:
120

What value should go in the red box

NeX [460]

I’m pretty sure it would be 4, since y= (x) which would be the numbers on the chart and then add 2
ex: y= (2) + 2
y= 4 and so on

The function f(x) = x2 is transformed to f(x) = −1.4x2. Which statement describes the effect(s) of the transformation on the gra

Romashka-Z-Leto [24]

Answer:

C) The parabola is narrower and reflected across the x-axis.

Step-by-step explanation:

The original parabola has equation:

$f(x) = {x}^{2}$

The transformed parabola has equation

$f(x) = - 1.4 {x}^{2}$

How wide the graph is can be determined by the absolute value of the coefficient.

The smaller the absolute value of the coefficient, the wider the graph.

Since

$|1| \: < \: | - 1.4|$

The original graph is wider than the transformed graph.

Also the negative factor tells us there is a reflection in the x-axis.

find real numbers a, b, and c so that the graph of the function y=ax^2+c contains the points (-1,6), (2,7), and (0,1)

Paraphin [41]

This gives you three simultaneous equations:

6 = a + c
7 = 4a + c
1 = c

c = 1

If c =1,

6 = a + 1
a = 5

This doesn't work in the second equation, so the quadratic that goes through these points is not in the form y = ax^2 + bx + c
Was there supposed to be a b in the equation?

The vertices of two rectangles are A(−5,−1),B(−1,−1),C(−1,−4),D(−5,−4) and W(1,6),X(7,6),Y(7,−2),Z(1,−2). Compare the perimeters

valkas [14]

The two rectangles are not similar. actually WXYZ is not a rectangle at all. it is a polygon but not a rectangle. hope the visual helps..
