Answer:
4 miles an hour
Step-by-step explanation:
Solve the following system using elimination:
{3 x - 4 y = -24 | (equation 1)
{x + y = -1 | (equation 2)
Subtract 1/3 × (equation 1) from equation 2:
{3 x - 4 y = -24 | (equation 1)
{0 x+(7 y)/3 = 7 | (equation 2)
Multiply equation 2 by 3/7:
{3 x - 4 y = -24 | (equation 1)
{0 x+y = 3 | (equation 2)
Add 4 × (equation 2) to equation 1:
{3 x+0 y = -12 | (equation 1)
{0 x+y = 3 | (equation 2)
Divide equation 1 by 3:
{x+0 y = -4 | (equation 1)
{0 x+y = 3 | (equation 2)
Collect results:
Answer: {x = -4, y = 3

The original photo is 4 by 6
The ratio of that is 4/6 or 2/3
Since the “wide” is extended to 12, you simply compare the ratio as 4/6=12/x and solve for x. Cross multiply and you should get 18 inches tall
For
|a|<b
assume
-b<a<b
for
|a|=b
assume
a=b and a=-b
|y+4|<1
-1<y+4<1
minus 4
-5<y<-3
A
|2t|-5=7
add 5
|2t|=12
assume
2t=12
2t=-12
divide by 2
t=6
t=-6
B is answer
|a|-3/4=-5/8
|a|-6/8=-5/8
add 6/8 to oths ides
|a|=1/8
a=1/8 and a=-1/8
A
