Answer:
x = 2
Step-by-step explanation:
x + 1 + 4 = 2x + 3
x + 5 = 2x +3
x + 2 = 2x
2 = x
x = 2
Use point-slope form.
But first let's find the slope.
(4, 2), (2, 4)
m = y2-y1/x2-x1
m = (4 - 2)/(2 - 4)
m = 2/-2
m = -1
So this is the slope, now we can plug this into the equation along with any point.
y - y1 = m(x - x1)
Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.
Let's plug in point (4, 2):
y - 2 = -1(x - 4)
This can be one of your options.
Distribute -1:
y - 2 = -x + 4
Add 2 to both sides:
y = -x + 6
This can be another of your options.
Add 'x' to both sides:
x + y = 6
This can be another of your options.
Rate for 1 mile is 1.75$+0.75$=2.50$
Jack has 10 $ to spend
when 2.50$ for 1 mile
so 10 $ for 10/2.50=4 mile he can travel
Answer:
96 square inches.
Step-by-step explanation:
From given picture we see that
BC=8 in
AD=10 in
Given that
AD=AB
Then AB=10 in
Apply Pythagorean theorem in triangle ABC to find AC
take square root
Then area of triangle ABC 
There are total 4 congruent triangles.
Then total area of the given figure = 4(24)=96 square inches.
