Answer:

slope = \frac{4}{5}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 3, 0 ) and (x₂, y₂ ) = (2, 4) ← 2 points on the line

m = \frac{4-0}{2-(-3)} = \frac{4}{5}

FIVE STARS AND BRAINLIEST FOR CORRECT ANSWER
Charra [1.4K]

For the given vectors \vec{a}=a_{1}\hat{i}+a_{2}\hat{j} and \vec{b}=b_{1}\hat{i}+b_{2}\hat{j}

The dot product of vectors a and b is defined as = \vec{a}.\vec{b}=(a_{1}\times b_{1}+a_{2} \times b_{2})

So, \vec{a}.\vec{b} = (4\hat{i}+3\hat{j}). (-4\hat{i}+4\hat{j})

\vec{a}.\vec{b}=(4\times(-4)+3 \times4)

= -16+12

= -4

Find the difference: (20x + 3) - (7x - 5) *
OlgaM077 [116]

Answer:

27x - 2

Step-by-step explanation:

First off, we use commutative property to get the like terms together.

(20x + 7x) - (3-5)

Now we can solve the equations inside the parenthesis.

27x - (-2)

Because these aren't like terms, this is as far as we can go. Meaning 27x - 2

is out answer.

expeople1 [14]

no. of boys : no.of girls

100 : 140

to get the simplest ratio you gotta divide both with a common factor

Because both 100 and 140 share a common factor of 20

the simplest ratio will be

100/20 : 140/20

5:7

5:7 is the simplest ratio
