Write an equation for a line that is parallel to 2x+5y=15 and passes through the point (-10, 3)

Lyrx [107]

Answer:

The equation of the line is,

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

Step-by-step explanation:

First, you have to write it in a form of y = mx + b :

$2x + 5y = 15$

$5y = 15 - 2x$

$y = 3 - \frac{2}{5} x$

$y = - \frac{2}{3} x + 5$

When both lines are parallel to each other, they will have to same gradient value. So the equation of the line is y = (-2/5)x + b. Next, you have to find the value of b by substutituting (-10,3) into the equation :

$y = - \frac{ 2}{5}x + b$

$let \: x = - 10,y = 3$

$3 = - \frac{2}{5} ( - 10) + b$

$3 = 4 + b$

$3 - 4 = b$

$b = - 1$

Complementary angels add up to 90°
so x+18°=90°
so x=90-18=72°

bill has a bike that weights 56 pounds . magda has a bike that weights 52 pounds. she add a bell and a basket to her bike. the b

pickupchik [31]

No because she's adding ounces plus 2 pounds so she's up to 54 pounds so... plus the 12 ounces and 8 ounces, and 12 ounces into 1 pound would be 0.75 so it's almost a pound....then 8 ounces into a pound would be 0.5 pounds so if you add the two 0.75 and 0.5 you would get 1.25 pounds... so 1.25 plus 54 pounds would not be 56 pounds...So No. Please mark brainliest:)!
