Answer:

Negative, because the product (-7)(-2) is positive, and the product (-5)(1) is negative and the product of a positive and a negative number is negative

Step-by-step explanation:

Negative, because there is an odd number of negative factors. The above explanation is reasonable, too.

What is the equation of the line which includes points (0,3) and (4,5)

laila [671]

Answer:

y = $\frac{1}{2}$ x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 5)

m = $\frac{5-3}{4-0}$ = $\frac{2}{4}$ = $\frac{1}{2}$

Note the line crosses the y- axis at (0, 3) ⇒ c = 3, thus

y = $\frac{1}{2}$ x + 3 ← equation of line

(WILL GIVE BRINALIST TO BEST ANWER) WHATS the measure of < 3

malfutka [58]

Answer:

∠3 = 60°

Step-by-step explanation:

Since g and h are parallel lines then

∠1 and ∠2 are same side interior angles and are supplementary, hence

4x + 36 +3x - 3 = 180

7x + 33 = 180 ( subtract 33 from both sides )

7x = 147 ( divide both sides by 7 )

x = 21

Thus ∠2 = (3 × 21) - 3 = 63 - 3 = 60°

∠ 2 and ∠3 are alternate angles and congruent, hence

∠3 = 60°

What is the sum of 52 and its additive inverse?

Lisa [10]

Hello there!

The additive inverse of any number just means to flip it's value.

For example;

The number "3" would have an additive inverse of "-3".
The number "-15" would have an additive inverse of "15".

Since we have "52", we can flip the value sign of it.
We now have -52 and 52.

Since the question asked us to sum our numbers, we need to add them.

-52 + 52 = 0

The sum of 52 and its additive inverse is 0.

I hope this helps!
