Answer:
y = 3x -1
Step-by-step explanation:
It is convenient to choose two points that have x-values 1 unit apart when computing the slope of the line (m). Here, we choose the points (-1, -4) and (0, -1).
... m = (change in y)/(change in x) = (-1-(-4))/(0-(-1)) = 3/1 = 3
The point (0, -1) tells you that the y-intercept (b) is -1.
Now you have the information you need to fill in y = mx + b:
... y = 3x -1
Answer:
∠A = 94°
Step-by-step explanation:
Two angles are called supplementary when their measures add up to 180°.
Therefore, if ∠A and ∠B are supplementary:
⇒ ∠A + ∠B = 180
⇒ (2x + 10) + (2x + 2) = 180
⇒ 4x + 12 = 180
⇒ 4x = 168
⇒ x = 42
To find ∠A, substitute found value of x into the expression for ∠A:
⇒ ∠A = 2(42) + 10 = 94°
$3,885 because if you add them all up you should get 1,518.77 then you subtract that from 5,403.77.
The number in the equivalent ratio is 6.
What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.
Where, x and y are individual amount of two quantities.
And, Total quantity gives after combine as x + y.
Given that;
The equivalent ratio is,
⇒ 1.2 : x = 30 : 150
Now,
Find the value of x in the equivalent ratio as;
⇒ 1.2 : x = 30 : 150
By definition of ratio we can formulate;
⇒ 1.2 / x = 30 / 150
Multiply by x, we get;
⇒ 1.2 = 30x / 150
Multiply by 150, we get;
⇒ 1.2 × 150 = 30x
⇒ 180 = 30x
Divide by 30 both side;
⇒ 180 / 30 = x
⇒ x = 6
Thus, The number in the equivalent ratio is 6.
