Slope= -3/2 Y-intercept= 175 Start at point 175, graph that point, then go down 3 then right 2, graph that point, repeat a few times then connect points for the line

Wow, lots of points, easy qeustion and nobody anwering

ok so

basically solve for y

6x+4y=700
minus 6x from both sides
4y=-6x+700
divide both sides by 4
y=-3/2x+175

ok so
y=mx+b
m=slope
b=yintercept or where the line crosses the y axis

so
y=-3/2x+175
yintercept is 175 so go 175 units up on teh y axis and put a point there

slope is -3/2
slope=rise/run
go 3 units down and 2 units to the right from that first point you ploted
that is new point
connect the 2 points to get graph, or input a value for x and get a value for y to get a point

basically just find 2 differn points and connect them to graph

I have attached graph

64p=-16+8p-40p^2 solve by factoring.

marusya05 [52]

Answer:

Solution set = {(-1,-2/5)]

Step-by-step explanation:

64p=-16+8p-40p²

64p-8p=-16-40p²

56p+16+40p²=0

40p²+56p+16=0

8(5p² +7p+2)=0

5p²+5p+2p+2=0

5p(p+1) +2(p+1)=0

(p+1)(5p+2)=0

p+1=0; 5p+2=0

p=-1; p=-2/5

Jeremy is driving to his friends house that is 60 miles away from his home the scale on Jeremy's map is 1 1/2 inches equivalent

defon

Answer:

The distance between their house on the map is 10 inches.

Step-by-step explanation:

In order to calculate the distance from Jeremy's friend house to his we can apply a rule of three in a way that 60 miles is related to "x" inches in the same proportion as "1 1/2" inches is related to 9 miles. Before applying that it'll be for the best if we convert the mixed fraction to a pure fraction as shown below:

$d = 1\frac{1}{2} = 1 + \frac{1}{2} = \frac{2}{2} + \frac{1}{2} = \frac{3}{2}$

Creating the rule of three:

$\frac{60}{9} \frac{\text{miles}}{\text{miles}} = \frac{x}{\frac{3}{2}} \frac{\text{inches}}{\text{inches}}\\\\9*x = \frac{60*3}{2}\\\\x = \frac{180}{18}\\\\x = 10 \text{ inches}$
