2(3x + 2 + x) = 6x + 4 + 2x = 8x + 4
A and D have the same solutions
Bisects means it cut it in half. So half of 50 is 25.
AngleDAC = 25
Answer:
Step-by-step explanation:
First you need to use your information to set up a proportion. (put your parts over the wholes and a variable in the blank spot.
<u>part </u> <u> part</u>
whole whole
<u>2 </u> <u>6</u>
x 150
Now you use the butterfly method, cross multiply the numerator and denominator and then divide that answer by the remaining numerator or denominator. This will give you the missing value for your variable.
150 x 2 = 300 300 ÷ 6 = 50
Answer:
Angle θ would be about 17.1 degrees.
Step-by-step explanation:
To figure out what Angle θ is, first we have to find the hypotenuse. You can easily do that by find the square root of BC² + AC².
c = √4² + 13²
Square 4 and 13 to get 16 and 169 respectively.
c = √16 + 169
Add 16 and 169 to get 185.
c = √185
Find the square root of 185 (I'll round to the nearest tenth.)
c = 13.60147 ≈ 13.6 units
To find angle β, divide AC by AB and find the inverse sine of that.
β = arcsin(13/13.6)
Divide 13 by 13.6. Round to the nearest thousandth.
β = arcsin(0.955)
β ≈ 1.2723 rad
To convert radians to degrees, multiply the radians by 57.2957795 for an approximate amount.
β ≈ (1.2723 * 57.2957795)°
β ≈ 72.8974203 ≈ 72.9 degrees
Now subtract 72.9 from 90 to get angle θ's measure of 17.1 degrees.
The first question is D because if the
y-intercept is 1 then every point moves down three units.
The second question is J because a vertical line is not a function so it can’t be a linear function.
