Step-by-step explanation: The identity property holds true for both addition and multiplication.

The statement 8 × 1 = 8 represents the identity property of multiplication.

The identity property of multiplication says that when we multiply 1 by any number, the product is equal to the original number.

In general terms, we can write the identity property of multiplication as

a × 1 = a where a is a variable which represents any number.

The zero property only holds true for multiplication.

The zero property of multiplication is shown here, 7 × 0 = 0. The zero property of multiplication says that if we multiply any number by 0, the product is always 0.

In general terms, we can write the zero property of multiplication as followed.

a × 0 = 0 where a is a variable that represents any number.

Jan has 35 teaspoons of chocolate cocoa mix and 45 teaspoons of French vanilla cocoa mix. She wants to put the same amount of mi

spin [16.1K]

Given that Jan has 35 teaspoons of chocolate cocoa mix and 45 teaspoons of French vanilla cocoa mix and that she wants to put the same amount of mix into each jar.

Given that she only wants one flavor mix in each jar and that she wants to fill as many jars as possible.

This question depicts a HCF (highest common factor) question where the maximum amount of jars of each flavor she can fill represent the multiple of the HCF of 35 and 45.

35 = 5 x 7
45 = 5 x 9

Thus the HCF of 35 and 45 is 5.

Therefore, the number of jars of French vanilla cocoa mix Jan will fill is 9.

12.) Find the x-intercept and y intercept of the following equation. 9x + 6y = -36

Alik [6]

Answer:

Thevalue of x-intercept is 0

and y intercept is-6.

Step-by-step explanation:

here,9x+6y=-36

9x = -36 - 6y

x=(-36 -6y)/9

x=(-12-2y)/9.........(i)

putting value of x in question

9[(-12-2y)/9]+6y=-36

-12-2y+6y= -36

-12+4y= -36

4y=-24

y=-6

puting value of x in equation (i)

x=(-12-2y)/9

x=(-12-2×-6)/9

x=0
