Answer:
x=20
Step-by-step explanation:
log3(4x+1) = 4
Raise each side to the base of 3
3^log3(4x+1) = 3^4
4x+1 = 3^4
4x+1 = 81
Subtract 1 from each side
4x+1-1 = 81-1
4x= 80
Divide by 4
4x/4 = 80/4
x = 20
Answer:
y = 3.75+1.74= 5.49=5.5 =5.5
4(3.75) - 2(5.5) =15 - 11 =4
Step-by-step explanation:
y = x+ 1.74 → -x + y = 1.74
(1/2)(4x - 2y = 4) → 2x - y = 2
Add two eq → x=3.74 and y=5.5
The problem says that u need replace but with the process before you can get the result easily.
y = 3.75+1.74= 5.49=5.5 ≠ 0
4(3.75) - 2(0) =15 ≠ 4
y = 4+1.74= 5.74=6 ≠ 4
4(4) - 2(4) =8 ≠ 4
y = 3.75+1.74= 5.49=5.5 =5.5
4(3.75) - 2(5.5) =15 - 11 =4
y = 5.5+1.74= 7.24 ≠ 0
4(5.5) - 2(4) =14 ≠ 4
Answer:
Last week jake ran One and Three-fourths miles(s)
Step-by-step explanation: First we need divide to see how many miles jake ran last week so 7 divided by for is the same as seven-fourths because the divison bar means to divide. Now that we have seven-fourths lets convert that to a mixed number witch is One and three-fourths
Please, when you present a list of numbers, such as 4, 8, 16, ..., separate them with commas or semicolons: 4, 8, 16, ...
If x^2 + y^2 = 16, then 16 represents r^2, and r = 4. r cannot be negative in this type of problem.
Answer:
<em>2.5</em>
Step-by-step explanation:
y2 - y1 = top
x2 - x1 = bottom
<em>y2 = -5</em>
<em>y1 = -7.5</em>
<em />
<em>x2 = -2</em>
<em>x1 = -3</em>
<em />
<em />
-5-(-7.5) = 2.5
-2-(-3) = 1
2.5 over 1 = 2.5
