Step-by-step explanation:

$\frac{20}{48} \times \frac{80}{44}$

Divide the fraction with 4

$\frac{20÷4}{48÷4} \times \frac{80÷4}{44÷4} = \frac{5}{12} \times \frac{20}{11}$

Reduce the number with factor 4

$\frac{5}{12÷4} \times \frac{20÷4}{11} = \frac{5}{3} \times \frac{5}{11}$

Multiply the fractions

$\frac{5 \times 5}{3 \times 11} = \frac{25}{33}$

$\boxed{\green{= \frac{25}{33} = 0.75}}$

Write in y= mx + b form: a line through (-3,1) having the same y-intercept as the graph of x-2y=-4

MariettaO [177]

Step-by-step explanation:

Aight, so the same intercept

$- 2y = - 4 - x = = = > \\ y = \frac{1}{2} x + 2$

m=½

$y = \frac{1}{2} x + b = = = > \\ now \: let \: us \: replace \: the \: point \\ 1 = \frac{1}{2} ( - 3) + b = = = > \\ \frac{5}{2} = b$

soooo

$y = \frac{1}{2} x + \frac{5}{2}$

The line with x-intercept of 10 and y- intercept of -2.

Yuri [45]

Answer:

y = $\frac{1}{5}$ x - 2

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

with (x₁, y₁ = x- intercept (10, 0) and (x₂, y₂ ) = y- intercept (0, - 2)

m = $\frac{-2-0}{0-10}$ = $\frac{-2}{-10}$ = $\frac{1}{5}$

The y- intercept c = - 2

y = $\frac{1}{5}$ x - 2 ← equation of line

How to solve 3 variable systems

AVprozaik [17]

Pick two pairs: 4x - 3y + z = - 10. 2x + y + 3z = 0. ... Eliminate the same variable from each system: 4x - 3y + z = - 10. 2x + y + 3z = 0. ... Solve the system of the two new equations: -5y - 5z = - 10. 5y - 7z = 34. ... Substitute into one of the original equations: - x + 2y - 5z = 17. ... Check: Does 2(1) + 4 + 3(- 2) = 0 ? Yes.
