Answer:

9/10

1/2+2/5

Since these fractions have different denominators, we need to find the least common multiple of the denominators.The least common multiple of 2 and 5 is 10, so we need to multiply to make each of the denominators = 10

1/2 ∗ 5/5 = 5/10

5/2∗ 2/2= 4/10

Since these fractions have the same denominator, we can just add the numerators

5/10+ 4/10 = 9/10

PLEASE HELP! urgent! Write the equation of a line in a slope-intercept form and standard form

m_a_m_a [10]

Answer:

$y = \frac{3}{4}x -3$ --- Slope intercept

$4y - 3x =- 12$ --- Standard form

Step-by-step explanation:

Given

The attached linear graph

Required

The equation

Select any two points on the line

$(x_1,y_1) = (0,-3)$

$(x_2,y_2) = (4,0)$

Next, calculate the slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

So, we have:

$m = \frac{0 --3}{4 - 0}$

$m = \frac{3}{4}$

The slope intercept is then calculated using:

$y = m(x - x_1) + y_1$

So, we have:

$y = \frac{3}{4}(x - 0) -3$

$y = \frac{3}{4}(x) -3$

$y = \frac{3}{4}x -3$

Multiply through bu 4

$4y = 3x - 12$

Subtract 3x from both sides

$4y - 3x =- 12$ --- Standard form

Answer:

Step-by-step explanation:

Midpoint = (x₁+ x₂)/2 , (y₁ +y₂)/2

= [(-1)+(-3))/2] , (-2 + 9)/2

= (-4/2) , (-7/2)

= (-2 , -3.5)
