Answer:
y=-5/3x+13.
Step-by-step explanation:
As a line that is perpendicular to anoher line has a slope that is the negative reciprocal of the line's original slope, we know that the slope of our new line is -5/3. As it passes point (12, -7), we can use the point slope formula which is y-y1=m(x-x1). So plug in, y+7=-5/3(x-12) and that gives us y+7=-5/3x+20 which gives our final answer of y=-5/3x+13.
I would have to say
Maria is 21
Jose 9
If Maria was 12 and Jose wasn’t born yet look at their ages in nine years.
Hope this helped.
30%of 68 = 30/100*68= 3*68/10=204/10=20.4
9y - 6y = 3y
3y + y = 4y
answer: 4y
Step-by-step explanation:
Step 1 : 0.5x + y = 1.5
0.8x - 0.2y =6
Step 2 : y = 1.5 - 0.5x
0.8x - 0.2 ( 1.5 - 0.5x ) = 6
Step 3 : y = 1.5 - 0.5x
0.8x - 0.3 + 0.1x = 6
Step 4 : y = 1.5 - 0.5x
0.9x = 6.3
Step 5 : y = 1.5 - 0.5* 7
x = 7 ( put 7 into the x value above )
Ans: y = -2
x = 7
You can ask me if you don't understand any step^^
