Answer:
no, because in a function, the input is paired or has only one output, but here 20 is paired to both 40 and 42, which doesn't make it a function.
Answer:
The expression that could be used is (-4)(3) + (-4)() ⇒ B
Step-by-step explanation:
Let us revise the distributive property:
<em>The product of a number and the sum of 2 other numbers equal to the sum of the products of the number with the other 2 numbers</em>
We will use this rule to solve the question
∵ The product of -4 and 3 = -4 × 3
→ We can right 3 as (3 + )
∵ 3 = (3 + )
∴ -4 × 3 = -4(3 + )
→ By using the rule above
∵ -4(3 + ) = (-4)(3) + (-4)()
∴ -4 × 3 = (-4)(3) + (-4)()
∴ The expression that could be used is (-4)(3) + (-4)()
The answer is 9. because... (8+9) + 32= 49
Answer:
5 + 7
Step-by-step explanation:
3 + 2 = 5, 4 + 3 = 7
To add fractions they're suppose to have the same base or denominator then u add the top
To subtract it's the same but u subtract the top
