Which choice shows +=7

Mathematics
1 answer:
V125BC [204]3 years ago
7 0

Answer:

y=-x +7 is the slope-intercept form and the graph is shown in the attachment.

Step-by-step explanation:

The given equation is

x + y = 7

We solve for y to get:

y =  - x + 7

This is now of the form, y=mx+c

This is called the slope-intercept form.

Since the slope is negative, the graph slopes backwards. Also the y-intercept is 7, so the graph will intersect the y-axis at 7

Y varies directly with x. If y=25 when x=5, find y when x =-4<br><br>y =​
alina1380 [7]

Answer:

y = -20

Step-by-step explanation:

Given that y varies directly with x it means changing x will also cause change in y

Mathematically it can be written as:

y∝x

Removing the proportionality symbol

y = kx

Given y=25 when x=5 Putting the values

25 = k(5)\\k = \frac{25}{5}\\k = 5

Now

y = 5x

We have to find the value of y when x = -4

Putting x=-4

y = 5(-4)\\y = -20

Hence,,

y = -20

A company makes paper labels for paint cans. As shown below, each can is in the shape of a cylinder
sineoko [7]

The company needs 41 labels on average, each minute.

<h3>What is the circumference of a circle?</h3>

The perimeter of a circle (circumference): 2 π radius

Replacing with the values given:

C = 2 (3.14) 2 = 12.56 cm

So, the area of one label is:

Area of a rectangle: length x width = 12.56 x 7 = 87.92 cm sq.

Now, the number of label be n

87.92 x n = 3612.64 cm2

n = 3612.64 / 87.92

n = 41.09

Hence, The company needs 41 labels on average, each minute.
