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)()
Answer:
7
Step-by-step explanation:
Because 35/5=7 so 1/5 of 35 would = 7
Answer:
Both equation represent functions
Step-by-step explanation:
The function is the relation that for each input, there is only one output.
A. Consider the equation
This equation represents the function, because for each input value x, there is exactly one output value y.
To check whether the equation represents a function, you can use vertical line test. If all vertical lines intersect the graph of the function in one point, then the equation represents the function.
When you intersect the graph of the function with vertical lines, there will be only one point of intersection (see blue graph in attached diagram). So this equation represents the function.
B. Consider the equation
This equation represents the function, because for each input value x, there is exactly one output value y.
When you intersect the graph of the function with vertical lines, there will be only one point of intersection (see green graph in attached diagram). So this equation represents the function.
Answer:
<u>There is no restriction to domain:</u>
<u>The range is to vertex coordinate of 1:</u>
