What is the equation of the line in slope-intercept form?
A y=x+8
By=2 - 8
y = 8x + 8
Dy = 8x - 8
Answer:
B. y = x - 8
Step-by-step explanation:
✔️First, find the slope of the line using two points on the line, say (0, -8) and (8, 0):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - (-8)}{8 - 0} = \frac{8}{8} = 1 [/tex]
slope (m) = 1
✔️Find the y-intercept (b):
The y-intercept is -8. The line intercepts the y-axis at y = -8.
b = -8
✔️Next, substitute m = 1, and b = -8 into y = mx + b:
Thus:
y = (1)x + (-8)
y = x - 8
The $230.00 digital camera Anne purchased was on sale for 15% off. What amount did Anne get off the price?
A $23
B $46
C $34.50
D $35.50
Answer: C $34.50
Step-by-step explanation: The 15% of 230 is 34.50, so the digital camera was $34.50 off.
Given points ( - 2, 3) and ( 9, 3 ) which expression can be used to find the distance between the two points?
Answer:
|-2| + |9|= 11
Step-by-step explanation:
d=(9−(−2))2+(3−3)2−−−−−−−−−−−−−−−−−−√
d=(11)2+(0)2−−−−−−−−−−√
d=121+0−−−−−−√

Select true or false to tell whether the following disjunctions are true or false. Use the truth table if needed.
5-3 = 15 or 7 + 5 = 20
True
False
9514 1404 393
Answer:
False
Step-by-step explanation:
The disjunction evaluates to ...
false or false
In order for an "or" statement to evaluate to True, at least one of the elements needs to be true. That is not the case here, so the disjunction is false.

solve for x if both sides are similar
Answer:
x = 12
Step-by-step explanation:
we can put this is a proportion: (new side 1) / (old side 1) = (new side 2) / (old side 2)
so in this case, 18 would be old side 1, x would be new side 1
12 would be old side 2, and 8 would be new side 2
plug these in: x/18 = 8/12
cross multiply 18 and 8: x = 144/12
now simplify: x = 12

========================================================
Explanation:
On the left side, there are two blocks labeled "y". This represents y+y which turns into 2y.
On this same side, we have three blocks labeled "1". So 1+1+1 turns into 3
Overall the expression for the left side is 2y+3
The right side is formed in the same way, just with different values.
On the right we have four "y" blocks leading to 4y. We also have two "1" blocks leading to 1+1 = 2. The expression for the right side is 4y+2
Ultimately we end up with the equation 2y+3 = 4y+2

Step-by-step explanation:
The table below shows the approximate percent of students who sent applications to two colleges in various years since 1985.
A regression equation for this line is y = -0.42x 19.26
What does the slope and y-intercept indicate?
a. The slope indicates that the percentage in 1985 should have been about 19%. The y-intercept indicates that the percent is falling at about 0.4% each year.
b. The slope indicates that the percent is falling at about 0.4% each year. The y-intercept indicates the percent in 1985 should have been about 19%
c. The slope indicates that the percent has remained the same each year. The y-intercept indicate the percent in 1985 should have been 22%
d. There is not enough information to determine what the slope and y-intercept indicate.
Answer: b. The slope indicates that the percent is falling at about 0.4% each year. The y-intercept indicates the percent in 1985 should have been about 19%
Step-by-step explanation:
The slope of straight line indicates the rate of change and in a regression equation is the m in: y = mx + c
In the regression equation of y = -0.42 + 19.26, the slope is -0.42 indicating that the rate of change has been -0.42% which means that the percent is falling at about 0.42% per year.
The y intercept (c) measures the rate at the origin and in this equation is 19.26. As the origin of the line is 1985, this means that the percent in 1985 should have been about 19%.

Suppose that 28% of the vehicles in a certain town are trucks. A person standing at an intersection waiting for a friend to pick him up. Let X = the number of trucks observed after 20 cars pass the observer. What is the expected value of X?
Answer:
The expected value is 5.6
Step-by-step explanation:
Here, we want to calculate the expected value of x
Mathematically, that will be the probability multiplied by the number of items
In this case, that will be ;
0.28 (28%) * 20 = 5.6
Which graph represents the equation y − 6 = -(x − 4)?
Answer: Am thinking (0,10)
Step-by-step explanation:
Answer:0,10, 10,0.
Step-by-step explanation:
The equation is in point-slope form, y − y1 = m(x − x1), where the slope, m, is -1, and the line goes through the point (4,6).
Use the slope to find a second point on the line. So, from the point (4,6), go down 1 unit and to the right 1 unit. Therefore, the line also goes through the point (3,5).
This is the graph showing a line that goes through (4,6) and (3,5).

This graph shows the solution to which inequality?
Answer:
The graph shows the solution of the inequality y > [tex]\frac{4}{3}[/tex] x - 2 ⇒ D
Step-by-step explanation:
In the inequality,
If the sign of inequality is ≤ or ≥, then the line that represents it must be a solid lineIf the sign of inequality is < or >, then the line that represents it must be a dashed lineIf the sign of inequality is > or ≥, then the shaded area must be over the lineIf the sign of inequality is < or ≤, then the shaded area must be under the lineFrom the given graph
∵ The slope of the line = [tex]\frac{2--6}{3--3}[/tex] = [tex]\frac{2+6}{3+3}[/tex] = [tex]\frac{8}{6}[/tex] = [tex]\frac{4}{3}[/tex]
∵ The y-intercept is (0, -2)
∵ The line is dashed and the shaded area is over the line
→ By using the 2nd and 3rd notes above, the line is dashed and
the sign of inequality is >
∴ The inequality is y > [tex]\frac{4}{3}[/tex] x - 2
∴ The graph shows the solution of the inequality y > [tex]\frac{4}{3}[/tex] x - 2
Solve for x.
