Which equation represents the line shown on the graph? y=-2x у y = 2x 1 y = -x + 2 x -3-2-1 1 2 3 -2 -3 y = x + 2

Karo-lina-s [1.5K]

Answer:

y = x + 2

Slope = rise / run

= 2 / 2 (or 1 bc 2 divided by 2 is 1)

The plotted point on the x axis is on 2

y = x + 2

algol13

Answer:

$A=\dfrac{1}{2}(10s+14d)$

Step-by-step explanation:

Given that,

He makes $10 per hour making sandwiches, and $14 per hour delivering orders.

Let there are s sandwiches and d is delivering orders.

Eric puts half of his total earnings in a savings account for college.

The expression that represents the total amount of money Eric saves for working s hours making sandwiches and d hours delivering orders.

$A=\dfrac{1}{2}(10s+14d)$

Hence, this is the required solution.

Using the completing-the-square method, find the vertex of the function f(x) =- 3x2 + 6x − 2 and indicate whether it is a minimu

svp [43]

F(x) = -3x² + 6x - 2
First, we make the coefficient of x² equal to 1
f(x) = -3(x² + 2x - 2/3)

Now, we must make the form a² + 2ab + b²
b = 2x/2x
b = 1

f(x) = -3(x² + 2x + 1² - 1² - 2/3)
f(x) = -3(x² + 2x + 1 - 5/3)
f(x) = -3(x + 1)² - 5

The vertex is (-1 , -5)
And this is the maximum point because the coefficient of the squared term is negative.

A rectangle has an area of 96 cm2 The length of the rectangle is 4 cm longer than the width. Work out the length and width of th

Svetach [21]

Area of a rectangle: 2(L+W)
length: 4+W

Area: 2(4+W) + 2W = 96
8+2W+2W = 96
8+4W = 96
4W = 88
W= 22cm

Calculate for length: 2L + 2(22) = 96
2L + 44 = 96
2L = 52
L = 26cm

• The length is 26cm and width is 22 cm.
