Answer:  5.25 or 5.5 [see note]

Step-by-step explanation:

1/4 (15 – 6) +3  [I'm not clear what is meant by the " : 12," so I left it out.]

1/4 (9) +3

9/4 + 3

2.25 + 3 = 5.25

===

If it is supposed to read

1/4 (15 – 6) +3/12

Then it would be

5.25 + 0.25 = 5.5

dani takes her two friends out for lunch. dani's meal costs $5. 72 and her friends' meal are $4. 89 and $7. 30. dani pays for the meals with a $20 dollar bill. how much change should she get?

Answers

Your answer is : $2.09

To find this answer you first need to find out how much money Dani spend.The equation for this is (5.72+4.89+7.30=17.91).The last step is to subtract the amount Dani spent by the amount she paid so new equation is (20.00-17.91=2.09)The answer is $2.09

$5.72+$4.89+$7.30=$17.91
$20.00-$17.91=$2.09

Dani will get $2.09 back. :)

​

Answers

Given the graph of the function, where the vertex is the maximum point at (-5,4):

We can establish the quadratic function in vertex form:

g(x) = -(x + 5)^2 + 4

To find the value of g(-1):

Substitute -1 as the input of the function:

g(-1) = -(x + 5)^2 + 4

g(-1) = -(-1 + 5)^2 + 4

g(-1) = -(4)^2 + 4

g(-1) = -12



To find the value of g(-3):

Substitute -3 as the input of the function:

g(-3) = -(x + 5)^2 + 4

g(-3) = -(-3+ 5)^2 + 4

g(-3) = 0


To find the value of x when g(x) = 4:
Since your vertex is (-5, 4), in which the y-coordinate is 4, then its x-coordinate is -5.

Therefore, the value of x when g(x) = 4 is -5.

if x:y = 2:5, find the value of (x + y) : (2x-3y)

Answers

Answer:

(x + y) : (2x-3y) = - 7/11

Step-by-step explanation:

The ratio is denoting:

x = 2

y = 5

Substitute your values into the equation's variables (x and y). Then solve.

(x + y) : (2x-3y)

(2 + 5 ) : [2(2) - 3(5) }

7 : [4-15]

7: -11

ratios can be turned into fractions.

7: -11 is the same thing as - 7/11

if you wrote the number 0.0009763 as a single digit times a power of ten, would the exponent be positive or negative? explain.

Answers

Answer:

10^n   means to multiply by 10

10^-n means to divide by 10 or multiply by 1 / 10

So .0009763 means 9.763 / 10000 = 9.763 * 10-4

can also write as 9.763E-4

If multiplying then the power of 10 would have to be negative

2y + 2x + 28 = 14 + 2x

use the slope-intercept form to graph the equation y=7x-4.

20 pts !!!

Answers

first, let's break the equation down.

y=7x-4

-4 represents your staring coordinate, or your y-intercept. This is because -4 does not have an x after so you know it is equal to your y value. So you start at (0,-4)

Now all you need to do is the y=7x part.

The 7x represents your slope.

Slope is equal to rise/run or y/x.

So for each coordinate, you go up 7 and to the right 1.

(0,-4)

(1,3)

(2,10)

Answer:

All you need to do is plug the values and then simplify!

Plug the value of x and y :

[tex] \longrightarrow \: \large{ \tt{ - 2 \times ( - 2) + 3 \times ( - 5)}}[/tex]

When negative integer is multiplied by negative integers , we get positive integer & when positive integer is multiplied by negative integer , we get negative integer.

[tex] \longrightarrow \large{ \tt4 + ( - 15){}}[/tex]

[tex] \longrightarrow \large{ \tt{4 - 15}}[/tex]

[tex] \longrightarrow{ \large{ \boxed{ \tt{ - 11}}}}[/tex]

Hence , Our simplified answer is -11 .

Use the table from Callie's Candies to answer the question.



Lily is buying candy for party favors. She needs 1.5 pounds of chocolates, 0.75 pounds of mints, and 15 lollipops. What is the total cost for the candy?
A.
$5.84

B.
$8.82

C.
$15.30

D.
$18.27

just show the letter

Answers

We can use logic along with 3 linear equations to solve this problem.

For the three types of candies, we will write a slope-intercept form equation. We know what m (slope) is for each equation, and there is no y-intercept because there is no starting point.

Equations:

Mints: y=.96x
Chocolates: y=4.70x
Lollipops: y=.07x

Using the given information, we can use the equations in function form. We know what x (input) is for all three types of candy, and that will give us y (output), which is the total for that candy type.

Solving:

Mints: y=.96(.75)
Chocolates: y=4.70(1.5)
Lollipops: y=.07(15)
We just input our information into the equations. Using logic, we know that we will have to multiply the cost of the candy by the number of candies to get the total of the three types.

Totals:

Mints: y=.72
Chocolates: y=7.05
Lollipops: y=1.05.
*Recall that y=total cost of candy for each type.

Now, we just simply add the three costs up to get the total sum that the candy will cost:

.72+7.05+1.05=8.82

Therefore, all the candy will cost $8.82.
