Mathematics
1 answer:
Soloha48 [4]3 years ago
4 0

Answer:

NO. Emma is not correct.

Step-by-step explanation:

✔️Initial value for Function A:

The initial value is the y-intercept of the graph. The y-intercept is the point at which the line intercepts the y-axis. From the graph given, the line intercepts the y-axis, at y = 2, when x = 0.

Initial value for Function A is therefore = 2

✔️Initial Value of Function B:

To find the initial value/y-intercept for Function B, do the following:

Using two pairs of values form the table, (2, 2) and (4, 3), find the slope:

Slope (m) = ∆y/∆x = (3 - 2) / (4 - 2) = 1/2

Slope (m) = ½

Next, substitute (x, y) = (2, 2) and m = ½ into y = mx + b, to find the intial value/y-intercept (b).

Thus:

2 = ½(2) + b

2 = 1 + b

2 - 1 = b

1 = b

b = 1

The initial value for Function B = 1

✅The initial value for Function A (2) is not the same as the initial value for Function B (1). Therefore, Emma is NOT CORRECT.

Write the equation for this line in y=blanks+blank<br><br> **Please see picture**
Diano4ka-milaya [45]

Equation for this line is y = -2x + (-4)

<u>Step-by-step explanation:</u>

Step 1:

Slope intercept equation for a line is of the form y= mx +  b, where m is the slope and b is the y-intercept.

Step 2:

Calculate slope of the given line.

⇒ m = (y2 - y1)/(x2 - x1) = (2 - (-2))/(-3 - (-1)

⇒ m = 4/-2 = -2

Step 3:

Find y-intercept

⇒ b = - 4

Step 4:

Substitute values to get equation

⇒ y = -x -4 or y = - (x + 4)

The area of a rectangle is 53.3 in2. If the width is 6.5 in, what is the perimeter of the rectangle?
Nuetrik [128]
You can find the length from
  A = LW
  53.3 in² = L×(6.5 in)
  (53.3 in²)/(6.5 in) = L = 8.2 in

The perimeter is twice the sum of length and width.
  P = 2(L +W)
  P = 2(8.2 in +6.5 in) = 29.4 in

The perimeter of the rectangle is 29.4 inches.
