Answer:

b=320; slope=-30

Step-by-step explanation:

if you look along the y-axis find the spot that the line intercepts and then that's b

now for the slope

find two points on the line, i chose(8 , 120) and (4 , 240)  

use the slope formula: y2-y1 over x2-x1

240-120=120 and 4-8= -4

so the slope is 120/-4 and that can be simplified to 30/-1 or -30

Igoryamba

Answer:

The value of given expression is 1.

Step-by-step explanation:

Consider the given expression is

\dfrac{e}{4}+2f-3

When e=12 and f=\dfrac{1}{2}.

Substitute e=12 and f=\dfrac{1}{2}  in the given expression.

\dfrac{12}{4}+2(\dfrac{1}{2})-3

On simplification we get

3+1-3

1

Therefore, the value of given expression is 1.

I need help on 11 and 12 and you don’t need to graph it
Lera25 [3.4K]

Answer:

Part 11) see the explanation

Part 12) The graph in the attached figure

Step-by-step explanation:

Part 11)

Let

x ----> the number of tickets is section A (cost $50 each)

y ----> the number of tickets is section B (cost $40 each)

we know that

At most means "less than or equal to"

x+y\leq 10 ----> inequality A

50x+40y\leq 450 ----> inequality B

Using a graphing tool

The solution is the shaded area

see the attached figure N 1

Three possible combinations are the points

(0,10),(5,5),(9,0)

That means

(0,10) ----> They buy 0 seats in section A and 10 seats in section B

(5,5) ----> They buy 5 seats in section A and 5 seats in section B

(9,0) ----> They buy 9 seats in section A and 0 seats in section B

Part 12)

Let

x ----> the number of hours Kendra works as a babysitter

y----> the number of hours Kendra works providing technical support

we know that

x+y\leq 80 ----> inequality A

At least means "greater than or equal to"

10x+15y\geq 1,000 ----> inequality B

using a graphing tool

The solution is the triangular shaded area

The graph in the attached figure N 2

soldi70 [24.7K]
Given:
bake sale at least $300
price of each pie is $6.00
let the number of pies be represented by x.

Write the inequality:
6x <u>></u> 300  

Solve the inequality:
6x <u>></u> 300
<u>÷6       ÷6</u>
  x <u>></u> 50

Graph the inequality.
y = 6x

x is the number of pies sold; x at least 50 and gradually increases.
y is the total sales
