Use x+2y=8
Subtract 2y to make
x=8-2y
Plug this in to the other equation
3(8-2y)+2y=6
Distribute the 3
24-6y+2y=6
Combine like terms
24-4y=6
Solve
18/4=y, 9/2=y
Plug and solve for x
X+2y=8
X+(2*9/2)=8
X+9=8
X=-1
answer:
29
step-by-step explanation:
22 + (96 - 40) / 8
22 + 56 / 8
22 + 7
= 29
First box is 6,464 feet. Second box is 4,061.5 feet.
Cincinnati Ohio à<span> Charlote North CA = a total of 336 miles
Cincinnati </span>à<span> Chicago Illinois = a total of 247 miles
Perry drove from Charlote to Chicago by passing Cincinati. Find the distance she drove.
=> Note that the distance from charlotte to Cincinnati is 365 then from Cincinnati to Chicago is 247
=> 336 miles + 247 Miles
=> 583 miles
Penny drove for a total of 583 miles from Charlotte to Cincinnati to Chicago.</span>
Slope-intercept form of a line:
y=mx+b
m=slope
We have this equation of a line:
y=2x+3
The slope of the line will be; m=2
Ohter line that is parallel to this line(y=2x+3) will have the same slope, therefore the slope will be: m=2
Point-slope form: we need a point (x₀,y₀) and the slope:
y-y₀=m(x-x₀).
We have thel point (-4,1) and the slope:
therefore:
y-1=2(x+4) (point-slope form)
y-1=2x+8
y=2x+8+1
y=2x+9 (slope-intercept form).
answer: the equation of the line that is parallel to this line y=2x+3 , is:
y=2x+9
