PLEASE HELP ASAP (8th grade question)

Mathematics
1 answer:
Ahat [919]3 years ago
6 0

Answer:

m∠2=35°, m∠1=35°

Step-by-step explanation:

∠2 and ∠4 equal 180° when added, so 180-145=35

all angles of a triangle equal 180°, so 180-∠3-∠2=∠1

180-110-35= 35

Jack and Jim sign up with an online music store. Jack chooses 15 downloads for $19.75, and Jim chooses 40 downloads for $43.50.
lina2011 [118]
The answer would be A. <span>The registration fee is $5.50, and the cost per download is $0.95.</span>

Solution
Let x = registration fee
y = cost/downloads

Jack
15y + x = 19.75 ; x = 19.75 - 15y
Jim
40y + x = 43.50

Thus,
40y + x = 43.50
40y + <span>19.75 - 15y = 43.50
</span>25y = 23.75
y= 0.95

for x,
<span>x = 19.75 - 15y</span>
x = 19.75 - 15( 0.95)
x= 19.75 -14.25
x = 5.5

Please resolve this problem for me! I've been having trouble with this for a while.

Answer:

a) 41

b) -31

c) 25/3

Step-by-step explanation:

The instructions explain what a function is pretty clearly.

Basically, whatever is in the parentheses next to the f, you plug in to the expression that is the function.

ex:     f(x) = x + 4

        f(5) = 5 + 4 = 9

Okay, onto the problems:

a) f(x) = 3x - 1

First, plug in 14, since that is given:

f(14) = 3(14) - 1

and solve.

f(14) = 42 - 1

f(14) = 41

So, 41 is the answer to a.

b) Do the same thing you did in problem a. Plug in the number inside the parentheses and solve.

f(-10) = 3(-10) - 1

f(-10) = -30 - 1

f(-10) = -31

-31 is the answer to b.

c) For this problem, you have to do a bit of algebra.

First, take the base function f(x):

f(x) = 3x - 1

Then, set f(x) = 24:

24 = 3x - 1

and solve by isolating x.

25 = 3x

\dfrac{25}{3} = x

x = \dfrac{25}{3}

25/3 is the answer to c.
