Answer:
side b= 11.489
Step-by-step explanation:
well I'm doing the exact same lesson currently and I just did the test on this exact question soo yeahh
The x-value at the point, denoted by d, is 18
<h3>Slope of a line </h3>
From the question, we are to determine the x-value at point B on the line
Given the points (x₁, y₁) and (x₂, y₂) on a line.
The slope, m, of a line with two points (x₁, y₁) and (x₂, y₂) on the line is given by the formula
m = (y₂ - y₁)/(x₂ - x₁)
From the given information,
Point A is (2, 1)
Point B is (d, 81)
That is,
x₁ = 2
y₁ = 1
x₂ = d
y₂ = 81
and
slope, m = 5
Thus,
5 = (81 - 1) / (d - 2)
5 = 80/(d -2)
5(d - 2) = 80
5d - 10 = 80
5d = 80 + 10
5d = 90
d = 90/5
d = 18
Hence, the x-value at the point, denoted by d, is 18

Step 1. Multiply 5 by y and you get 5y
Step 2. Multiply 5 by .4(2/5)
Step 3. Your equations will look like 5y+2=-13
Step 4. Subtract 2 from its self and -13
Step 5. Your equation will be 5y=-15
Step 6. Divide 5 from both sides
Step 7. Your answer is y=-3
Answer:
25-50
Step-by-step explanation:
Since the graph shows us only values of x that are between 25 and 50, this is the correct answer.
We can interpolate with known data. However, once the interpolation occurs, and we approximate the data for a line of the form <em>y = mx + b</em> (m <0 , linear negative association), we could find the other values of y for a wider range of x values.
Answer:
x - 1 is not a factor.
Step-by-step explanation:
By the Factor theorem if x - 1 is a factor then f1) = 0:
f(1) = 4*1^3 + 3*1^2 - 4*1 + 3
= 4 + 3 - 4 + 3
= 6 so it is not a factor.
