Answer:
x-intercept: (-5,0)
y-intercept (0,25)
or in standard form 5x - y = -25
Step-by-step explanation:

6. 12.5 cm
7. 0.7241
Step-by-step explanation:
6.
You have 2 right triangles. You can use the Pythagorean theorem for each one.
a^2 + b^2 = c^2
Let y = length of vertical side between triangles.
Left triangle:
5^2 + y^2 = 13^2
25 + y^2 = 169
y^2 = 144
y = 12
Right triangle:
3.5^2 + 12^2 = x^2
12.25 + 144 = x^2
x^2 = 156.25
x = 12.5
Answer: x 12.5 cm

For <X, 2.0 ft is adj leg. 2.9 ft is hyp.
cos X = 2.0/2.9 = 0.6897
X = cos^1 0.6897 = 46.397 deg
sin X = sin 46.397 deg = 0.7241
Step-by-step explanation:
the first one is equivalent : Adding property is applied
the second one is not equivalent.
Answer:
g(3a – 6) = a - 4
Step-by-step explanation:
g(x) = 1/3x - 2
g(3a – 6) = 1/3(3a – 6) - 2
= a - 2 - 2
= a - 4
Answer:
3.99 inches
Step-by-step explanation:
<u><em>The correct question is</em></u>
The function f(x) = 3(1.1)^x gives the length (in inches) of an image after being enlarged by 10% x times.
What is the length of the image after it has been enlarged 3 times? Round your answer to the nearest hundredth
we have
This is a exponential growth function
where
f(x) represent the length (in inches) of an image
x is the number of times the image is enlarged
so
For x=3
substitute in the exponential equation
