-√(81/9)+11 = -√9 +11 = -3+11 = 8
2√(100/4) - 23 = 2*√25 - 23 = 2*5 - 23 = -13
Answer
We know that this is a straight line, so it will follow the slope intercept equation:
y = mx + b.
To solve this problem, we need to plug in the x and y values for one point to get b, and then we will know the equation for the line, which is valid for all points.
x = −4
y = −3
m = 1/2
Let's start by solving for b:
b = y − mx
Now we can plug in numbers:
b = −3 − (1/2 × −4)
b = −3 − (−2)
b = −3 + 2
b = −1
Now that we know m and b, we can plug into our original equation:
The equation is y = 1/2x − 1.
Answer:
√(209)
Step-by-step explanation:
Since <B is a right angle, AC is the hypotenuse and AB and BC are legs.
(AB)² + (BC)² = (AC)²
(4 mm)² + (BC)² = (15 mm)²
16 mm² + (BC)² = 225 mm²
(BC)² = 209 mm²
BC = √(209) mm
Answer:
ask your mom or dad
Step-by-step explanation:
Cannot be determined because if your only given two thing (FG and the angle measure of F) thats not enough informations. The only way you know if a triangle is similar with only two pieces of information would be for the angle angle postulate.
