Find the Equation Using Two Points (-3,-7) (-1,4)

Mathematics
1 answer:
dexar [7]2 years ago
6 0

Answer:

equation= y-y¹=m(x-x¹)

where m = gradient or slope

slope= <u>y²</u><u>-</u><u>y</u><u>¹</u>

x²-x¹

= <u>4--</u><u>7</u>

-1--3

= <u>4+7</u>

-1+3

= <u>1</u><u>1</u>

2

= 5.5

equation= y-4=5.5(x--1)

= y-4=5.5(x+1)

y-4= 5.5x+5.5

y= 5.5x+5.5+4

y= 5.5x+9.5

Sophia‘s favorite homemade cookie recipe requires one cup of chocolate chips for 10 servings if the number of cups required for
weqwewe [10]

Answer:

3 cups

Step-by-step explanation:

We can use a proportion to find how many cups of chocolate chips she needs for 30 servings. Assuming c = cups of chocolate chips and b = batches

\frac{c}{b}

\frac{1}{10} = \frac{c}{30}

We can now multiply the diagonal values that don't include the missing variable (30 and 1) and then divide it by the value that is diagonal to the variable (10)

30 \cdot 1 = 30\\30 \div 10 = 3

Therefore, she needs 3 cups of chocolate chips to make 30 servings.

Serial numbers for a product are to be made using 2 letters followed by 3 digits the letters are to be taken from the first 6 le
kipiarov [429]

Answer:

Step-by-step explanation:

We have to make 5 place serial number with first two as alphabets and last three as digits.

The alphabets are bonded to first 6 ( A, B, C, D, E, F) where as digits are 10 (say 1 to 10).

Let the serial number be S1 S2 S3 S4 S5.

For Alphabets

For S1 we have 6 alphabets.

Now for S2 we are left with 5 alphabets since there is no repetition one alphabet will be fix for S1.

So the possible combination for S1 S2= 6x5=30.

For Digits

We did the same as we did for alphabets, for S3 we have 10 possibilities, and for S4 and S5 9 and 8 respectively due to the no repetition condition.

So the possible combinations for S3 S4 S5 = 10x9x8=720

So the total number of serial numbers are 30+720=750.
