sylvia bought 4 bananas for 50 cents each and 1 apple for 80 cents. wire a numerical expression to represents this situation.

4b = 50; 1a = 80

Step-by-step explanation:

So let's say that bananas = b and apple = a

Then we could set up the equations that are:

4b = 50 (cents)

1a = 80 (cents)

That means we have 2 equations of 4b = 50 and 1a = 80

Step-by-step explanation:

banana = b = 50¢ = $.50

apple = a = 80¢ = $.80

Total cost of fruit = f

She bought 4 bananas for .50 each so we multiply 4*.50 to find the total cost of the bananas and she bought 1 apple for .80, so we add them together to get the total cost of the fruit, f.

4b + a = f     Now substitute the values.

(4*.50) + .80 = f       This is you expression, let's solve for fun.

(4*.50) + .80 = f

2 + .80 = f

$2.80 = f   Sylvia spend $2.80 on the fruit.

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
