Fiesta28 [93]3 years ago
8 0

Answer:

if f(x)= -4x+3

f(-5)= 23

Step-by-step explanation:

first you substitute x for -5

f(-5)= -4(-5)+3

then you multiply

-4(-5)

f(-5)=20+3

you get the positive 20 because negative times negative equals positive

then you just add the rest (20+3) which will give you your answer

f(-5)= 23

Using it's concept, the range of the function is given by:

y ≥ 1

<h3>What is the range of a function?</h3>


The range of a function is composed by the set that contains all output values for the function. Considering the graph of the function, the range is given by all the values of y, which compose the vertical axis of the graph.

Looking at this graph, the function assumes values of 1 and greater, hence the range of the function is given by:

y ≥ 1.

The system of equation that will represent her situation is as follows:

1.39b + 2.49m = 50.73

1.29b + 2.69m = 51.63

<h3>How to represent system of equation?</h3>

At store A she will pay a total sum of $50.73 for bread and milk.

At store B she will pay a total sum of $51.63  for bread and milk.

Therefore, the system of equation that will represent her situation is as follows:

where

  • b = number of bread
  • m = number of milk

Therefore,

1.39b + 2.49m = 50.73

1.29b + 2.69m = 51.63

$22,102 is invested, part at 11% and the rest at 7%. If the interest earned from the amount invested at 11% exceeds the interest
Yuliya22 [10]
X + y = 22,102
.11x = .07y + 913.46  =      x= (7/11)y + 8304.18

((7/11)y + 8304.18) + y = 22,102

(18/11)y = <span>13797.82
</span>
y= 13797.82/(18/11)

y=8432.00 

8,432.00 dollars are invested at 7%
13,670.00 dollars are invested at 11%

Check
.07 x 8432=  590.24
.11 x 13,670 = 1503.70

1503.70 - 590.24 = 913.46
