If They have 7 cups of sprinkles then you would need 1/8 of a cup for each Sundae, you would have to multiply 8 by 7 to find your answer.

Answer: Matt's Ice Cream Shoppe can serve 56 Sundaes

Hope this helps

Which equation shows y=−12x+4 is in standard form? 2x + y = 8 2x−y=8 x + 2y = 8 x+2y=−8

drek231 [11]

Answer:

Step-by-step explanation:

The standard form of an equation of a line:

$Ax+By=C$

We have:

$y=-\dfrac{1}{2}x+4$

Convert:

$y=-\dfrac{1}{2}x+4$ <em>multiply both sides by 2</em>

$2y=-x+8$ <em>add x to both sides</em>

$x+2y=8$

I need help with #2 and #6 pleaseeeeee

Answer:

Area of the rectangle = x² - 3x - 10

2019

Step-by-step explanation:

Length of the rectangle = x + 2

Width of the rectangle = x - 5

Area of the rectangle = length × width

= (x + 2) (x - 5)

= x² + 2x - 5x - 10

= x² - 3x - 10

Area of the rectangle = x² - 3x - 10

C = 20t² + 135t + 3050

Where

C = the number of new cars

t = year the number of new cars was purchased

t = 0 corresponds to 1998

Find the when c = 15,000

C = 20t² + 135t + 3050

15,000 = 20t² + 135t + 3050

20t² + 135t + 3050 - 15,000 = 0

20t² + 135t - 11,950 = 0

4t² + 27t - 2390 = 0

Solve using quadratic equation

t = -b ± √b² - 4ac / 2a

= -27 ± √27² - 4(4)(-2390) / 2(4)

= -27 ± √729 -(-38240) / 8

= -27 ± √729 + 38240 / 8

= -27 ± √38969 / 8

= -27/8 + √38969/8 or 27/8 - √38969/8

= -3.375 + 197.41/8 or -3.375 - 197.41/8

= -3.375 + 24.67625 or -3.375 - 24.67625

t = 21.30125 or - 28.05125

t cannot be negative

Therefore,

t = 21.30125

To the nearest whole number

t = 21

Recall,

t = 0 corresponds to 1998

Therefore

1998 + 21 = 2019

c = 15,000 in the year 2019

50 points but please give a helpful answer <3

Rasek [7]

They are all (SAS)side angle side except for the bottom right one. This is because the question does not give the little ticks to show that one side is the same as the other. It is not good enough to assume they are congruent without proof.

quadrilateral WXYZ is reflected across the line y=x to create quadrilateral W’X’Y’Z'. What are the coordinates of quadrilateral

rosijanka [135]

Explanation

We are required to determine the coordinates of W’X’Y’Z' when WXYZ is reflected across the line y = x.

This is achieved thus:

From the image, we can deduce the following:

$\begin{gathered} W(-7,3) \\ X(-5,6) \\ Y(-3,7) \\ Z(-2,3) \end{gathered}$

We know that the following reflection rules exist:

Therefore, we have:

$\begin{gathered} (x,y)\to(y,x) \\ W(-7,3)\to W^{\prime}(3,-7) \\ X(-5,6)\to X^{\prime}(6,-5) \\ Y(-3,7)\to Y^{\prime}(7,-3) \\ Z(-2,3)\to Z^{\prime}(3,-2) \end{gathered}$

Hence, the answers are:

$\begin{gathered} \begin{equation*} W^{\prime}(3,-7) \end{equation*} \\ \begin{equation*} X^{\prime}(6,-5) \end{equation*} \\ \begin{equation*} Y^{\prime}(7,-3) \end{equation*} \\ \begin{equation*} Z^{\prime}(3,-2) \end{equation*} \end{gathered}$

This is shown in the graph bwlow for further undertanding:

A) 5t - 6= 3 - 41<br><br> Me ajuda!!!! Por favor

nirvana33 [79]

Answer:

t= -32/5

Step-by-step explanation:

1. Simplify 3-41= -38 5t-6 = -38

2. Add 6 to both sides 5t= -38+6

3. Simplify -38+6=-32 5t= -32

4. Divide both sides by 5 and it should give you t = − 32/5

If you want to check your answer 1. 5t-6 = 3-41 let t = -32/5 5× -32/5 -6 = 3-41

2. Cancel 5 -32 -6 = 3-41

3. Simplify -32-6= -38 -38= 3-41

4. Simplify 3-41= -38

-38=-38 and that how you check your answer to see it was right.
