Hey mate!
You stuck?
^3 The cube root of 125=5
^2 The square root of 35=5.91
^3 The cube root of 64=4
^2 The square root of 38=6.16
Therefore your answer would be x2= 38, because 6.16 is greater than the other sums.
Hope this helps! :) (Don't forget Brainliest) :)
Answer:
x=4
Step-by-step explanation:
-4+3x=8
+4 +4
<u>3x</u>=<u>12</u>
3x 3x
x=4
pH = f(x) = -log₁₀x
1. Graphs
I used Excel to calculate the pH values and draw the graphs (see the Figure).
f(x) and f(x) +1 are plotted against the left-hand axis, while f(x+ 1) is plotted against the expanded right-hand axis.
The points at which pH = 0 and pH = 1 are indicated by the large red dots.
2. x = 0.5
When x = 0.5, pH ≈0.30. The point is indicated by the red diamond.
3. Transformations
(a) ƒ(x) = -log(x) + 1
This function has no y-intercept, because log(0) is undefined.
(b) ƒ(x +1) = -log(x + 1)
f(0) = -log(0 + 1) = -log(1) = 0
This function has a y-intercept at (0,0).
hope this helps please mark me brainliest!
A). They are supplementary angles meaning they add up to 180
So
B) (12x+8)+(3x+7)=180
12x+8+3x+7=180
15x+15=180
-15 -15
15x=165
15/15x=165/15
x=11
Angle 1 is
12x+8
12(11)+8
132+8
140
Therefore measure of angle 1 is 140°
Angle 2
3x+7
3(11)+7
33+7
40
Measure of angle 2 is 40°
