Answer:

equation of the line: y=1/2x-1

slope :1/2x

y intercept: -1

Step-by-step explanation:

using y1-y2/x1-x2:

-1-0/0-2= -1/-2=1/2

the slope is 1/2.

plug in the numbers from the given points to find the y intercept:

-1=1/2•0+b

b= -1

the y intercept is -1.

with that, you've gotten the slope and the y intercept, which means you just have to plug them into y=mx+b.

so, the equation of the line is y=1/2x-1

child admission is $5.90 and adult admission is $9.10 . 175 tickets were sold for a total sales of $1282.10 . How many child tic

WITCHER [35]

Answer:

Child tickets sold: 97

Step-by-step explanation:

Step 1: Write out system of equations

5.90x + 9.10y = 1282.10

x + y = 175

Step 2: Rewrite 2nd equation

y = 175 - x

Step 3: Substitution

5.90x + 9.10(175 - x) = 1282.10

Step 4: Distribute

5.90x + 1592.5 - 9.10x = 1282.10

Step 5: Combine like terms

-3.2x + 1592.5 = 1282.10

Step 6: Isolate x

-3.2x = -310.4

x = 97

And we have our final answer!

Answer:8 1/4 cups

Step-by-step explanation:

All you must do is multiply 2.75 (which is 2 3/4 in decimal form) by 3 since Wendy is baking a TRIPLE recipe. So, the work will look like this: 2.75x3=8.25 or 8 1/4 cups of flour.

Answer:

A: (b) 320 is what percent of 400

B: 80%

Step-by-step explanation:

Part A:

This is a reading comprehension question. You are told that ...

$320 is the amount needed

$400 is the amount earned

and you are asked to find ...

what percent of the amount earned is the amount needed?

The question can be rephrased as ...

the amount needed is what percent of the amount earned?

Filling in the amounts you are told, the rephrased question becomes ...

$320 is what percent of $400 . . . . . matches choice (b)

Part B:

If we let x represent "what percent", then we can write the above question as ...

320 = x · 400

Dividing by 400 gives ...

320/400 = x = 0.80 = 80%

That is, 320 is 80% of 400.
