The property used is: Multiplicative identity

Step-by-step explanation:

We need to identify the property in the equation : -3\times 1=-3

The property used is: Multiplicative identity

Multiplicative identity

The multiplicative identity property is defined as if you multiply a number by 1, the result of multiplication is that original number.

In the given expression -3\times 1=-3 -3 is multiplied by 1 to get -3 so, multiplicative identity.

Which property is used to simplify the expression 5(3x +18) to 15x+90
natka813 [3]

Answer:

Distributive

Step-by-step explanation:

You distribute the 5 into 3x+18, multiplying it by each part of the equation (each part is separated by one of these signs: +, -, x, or /) to get 15x (from 5 x 3x) plus 60 (from 5 x 18).

Determine the standard form of the equation of the line that passes through (-6,6) and (3,-2)
Simora [160]

Answer:

y=(8/9)x + 4 and 2/3

Step-by-step explanation:

the slope of this line:

change in y/change in x

change in y=6-(-2)=8

change in x=-6-3=-9

change in y/change in x= 8/9

8/9 is the slope, so you plug it in for m in the standard form equation. You then use one point's x and y values to substitute for x and y in the equation, and solve for b, which is the y intercept

y=mx+b

y=(8/9)x+b

-2=(8/9)*3+b

-2=8/3+b

-4 and 2/3=b

Find the value of X and the missing angle
GuDViN [60]

Answer:

x = 10

missing angle = 83°

Step-by-step explanation:

These are supplementary angles meaning they have a sum of 180°.

8x + 3 + 97 = 180

8x + 100 = 180

8x + 100 - 100 = 180 - 100

8x = 80

x = 10

Substitute the value for the variable.

8(10) + 3

80 + 3

83
