The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We have the points (look at the picture) (0, 1) and (-2, -2). Substitute:
![m=\dfrac{-2-1}{-2-0}=\dfrac{-3}{-2}=\boxed{\dfrac{3}{2}}\to\boxed{D}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B-2-1%7D%7B-2-0%7D%3D%5Cdfrac%7B-3%7D%7B-2%7D%3D%5Cboxed%7B%5Cdfrac%7B3%7D%7B2%7D%7D%5Cto%5Cboxed%7BD%7D)
log(4)x + log(4)(x + 5) = 6
log(4)x + log(4)x + log(20) = 6
log(8)x + log(20) = 6
<u> - log(20) - log(20)</u>
<u>log(8)x</u> = <u>6 - log(20)</u>
log(8) log(8)
x ≈ 0.999
Answer:
1: 36° 2: 122° 3: 122° 4: 38°
Step-by-step explanation:
First start out by getting 2 and 3. so 58+angle 3 has to sum to 180° since they are supplementary and are a straight line. So 180-58=122. Angle 2 is the same since theyre vertical. then since a triangle has 180° total, you subtract from 180 to find the final angle measurement.
Answer:
Step-by-step explanation:
1. your kinda doing the same thing
2. solving problems is somewhat like math
3. you solve problems in math
Answer: 15 boys
Explanation: ratio 5:7
5 + 7 = 12
Number of boys = 5/12 × 36
