Answer:
The equation of a line in slope-intercept form is y = mx + b
where m is the slope
and b is the y-intercept.
For example,
in the equation y = 9x - 7
the slope is 9
and the y-intercept is -7, which means that the line crosses the y-axis at the point (0, -7)
If your question you are given m=3/8 and you can find the value of b from the given y-intercept.
Step-by-step explanation:
The slope-intercept form of a linear equation is:
y
=
m
x
+
b
Where
m
is the slope and
b
is the y-intercept value.
Substituting gives:
y
=
3
x
+
7
Answer:
Step-by-step explanation:
1 km= 1000 m
1 dam= 10 m
8 km= 8000m
700 dam = 7000m
so Plane A
plane A is higher by 700m!

Answer:
x = 27
Step-by-step explanation:
To find the value of x, create a proportion. A proportion is two equal ratios for similar figures. The two triangles are similar because they are the same shape but not the same size. Create ratios between corresponding sides of figures.
To solve for x, cross multiply:
(x+8)(14) = (10)(2x-5)
14x + 112 = 20x -50
112 = 6x - 50
162 = 6x
27 = x
Answer:
30.14
Step-by-step explanation:
- The formula for cirumference is 2(pi)r
- If the diameter equals 9.6 then the radius is 4.8
- 4.8 times 2 equals 9.6
- 9.6 times 3.14(pi) equals 30.144 which could be rounded to 30.14
Subs x = -5 into f(x) = 4
f(-5) = 4 (answer)
