Answer:
4x + y = 13
Step-by-step explanation:
1. Change 4x + y -2=0 into slope intercept form to find the slope:
y = -4x +2 The slope is -4
2. Plug in x, y and m into y = mx + b
-3 = -4 (4) + b
-3 = -16 + b
13 + b
3. Plug m and b into equation y = mx + b
y = -4x + 13
4. Change equation into standard form:
4x - y = 13
Answer:
IT EITHER B OR D BECASUE THOSE SEEM TRUE AND ALL BUT I DONT TRUST A AND C SO DONT MAKE THE WRONG MOVE MY GUY
Step-by-step explanation:
For the second question
3/4-1/3
3•4 12
1•4
12-4=8
8/12= 2/3
There should be 2/3 of a quart left
Answer: x=5.6 or 5 3/5
Step-by-step explanation:
Cross multiplication is when you have two fractions (ratios) that are equivalent and you can multiply the numerator of the first one by the denominator of the second one, and the denominator of the first one by the numerator of the first one. The answers to these two are equivalent.
So, 5x/8 = 7/2
10x=56
x=5.6
x= 5 3/5
3x-25=14
First, you'll add the 25 to the other side of the equation because its negative. 25+14 =39. then you'll divide these by 3. (because it says 3 times what curtis spent.)
39÷3=13. so the answer is 13. curtis spent 13 dollars shopping.
