Answer:
[tex]no \: solution[/tex]
Step-by-step explanation:
1) Expand.
[tex]7a + 5a + 15 = 8a + 4a+ 8[/tex]
2) Simplify 7a + 5a + 15 to 12a + 15.
[tex]12a + 15 = 8a + 4a+ 8[/tex]
3) Simplify 8a + 4a + 8 to 12a + 8.
[tex]12a + 15 = 12a + 8[/tex]
4) Cancle 12a from both sides.
[tex]15 = 8[/tex]
5) Since 15 = 8 is false, there's no solution.
[tex]no \: solution[/tex]
Therefor, this equation has no solution.

Answer:
x=7
Step-by-step explanation:
Step 1: Cross-multiply.
9(x−4)/6=x+2/2
9(x−4)*(2)=(x+2)*(6)
18x−72=6x+12
Step 2: Subtract 6x from both sides.
18x−72−6x=6x+12−6x
12x−72=12
Step 3: Add 72 to both sides.
12x−72+72=12+72
12x=84
Step 4: Divide both sides by 12.
12x/12=84/12
x=7

Consider the graph of the function f(x) = e^x.
Answer:
Option A
Step-by-step explanation:
Equation of the graph → f(x) = eˣ
Range of the given function is (0, ∞).
If the graph of the given function is translated by 3 units up.
New function will be,
g(x) = eˣ + 3
And the range of the new function will be (3, ∞).
Option A will be the correct option.
The range of the new function will be (3, ∞).
What is the range of a function ?
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain

Answer:
x should be 55
Step-by-step explanation:
the acute angle is 55 and we know that the whole horizontal is 180 so calculate 180-55 to find the obtuse angle which is 125. Then subtract 70 from that to isolate for x and you get 55.

Step-by-step explanation:
[tex]A = \frac{1}{2} (b+c)h\\[/tex] -> This is the original equation
[tex]\frac{A}{h} = \frac{1}{2} (b+c)\\[/tex] -> Divide by h on both sides
[tex]2\frac{A}{h} = b+c\\[/tex] -> Multiply both sides by 2
[tex]2\frac{A}{h}-b = c\\[/tex] -> subtract b from both sides

Given that ℓ1∥ℓ2 and the measure of ∠c = 44°, find the measures of angles a and b.
m∠a =
°
m∠b =
°
Answer:
<a = 44 degrees
<b = 136degrees
Step-by-step explanation:
From the given diagram;
<a = <c (alternate interior angle)
Since <c = 44 degrees, hence <a = 44 degrees
Also the sum of a and b is supplementary hence;
a + b = 180
44 + b = 180
b = 180 - 44
b = 136degrees
Hence m<b =136degrees

The country of Sylvania has decided to reduce the number of its illiterate citizens by 3/5 each year. This year there are 9000 illiterate people in the country.
Write a function that gives the number of illiterate people in Sylvania, P(t), t years from today
Answer:
P(t)= 9000(0.4)^t
Step-by-step explanation:
Generally, we have an exponential function as follows;
P(t)= I(1 - r)^t
This case represents a decay ( decrease in value)
from what we have;
I represents the initial value, whereas r is the rate of change
From the question, we have that the change rate is the fraction 3/5
Writing this as a decimal, it is 0.6
substituting this back into the equation, we have;
P(t)= I(1-0.6)^t
P(t)= I(0.4)^t
I in this case is 9,000
So we have it that;
P(t) = 9000(0.4)^t
