Write the equation of a line in slope-intercept form that passes through (0, 7) and has a slope of -23.
Answer:
y = -23x + 7
Step-by-step explanation
We are using the equation y = mx + b.
The slope (m) is -23, so it would be y = -23 + b.
b is the y-intercept, and the ordered pair that gives us the y-intercept is (0,7).
Remember that the y-intercept is what the y-coordinate is equal to when the x-coordinate is 0.
Determine the value of x.
4x + 20% 2x + 60%
(A) X= 10°
(B) x = 20°
(C) X= 30°
(D) x = 40°

Step-by-step explanation:
After a tropical storm in a certain state, news reports indicated that 19 percent of households in the state lost power during the storm. A state engineer believes that estimate is too low. The engineer will collect data to perform a hypothesis test on the proportion of all households without power. Which of the following are the appropriate hypotheses for such a test?
Answer:
D
Step-by-step explanation:
The null hypothesis is that p=0.19. The engineer says that this estimate is too low, meaning he believes the true proportion is greater than 0.19 - p>0.19. Because this is a proportion of ALL houses in the state, we use p rather than phat, leaving D as the correct answer.

Answer:

Step-by-step explanation:
A Parallel Line means the slope must be the same as the Given Line. A Perpendicular Line means the slope must be the negative reciprocal of the Given Line.
For Row A: Parallel is 12, Perpendicular is 6
For Row B: Parallel is 2, Perpendicular is 11
For Row C: Parallel is 9, Perpendicular is 16
For Row D: Parallel is 4, Perpendicular is 13
In Row E's case, 0 doesn't have a negative reciprocal, so you go with the equation that has a straight line down but no Y-Intercept.
For Row E: Parallel is 15, Perpendicular is 7
Row A = 72
Row B = 22
Row C = 144
Row D = 52
Row E = 105
Sum = 395
Code = 395 × 3 = 1185
A line passes through the point (–6, –3) and has a slope of 2/3 . Which point is on the same line?
Answer:
The point (0, 1) represents the y-intercept.
Hence, the y-intercept (0, 1) is on the same line.
Step-by-step explanation:
We know that the slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven
The point (-6, -3)The slope m = 2/3Using the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointIn our case:
m = 2/3(x₁, y₁) = (-6, -3)substituting the values m = 2/3 and the point (-6, -3) in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-3\right)=\frac{2}{3}\left(x-\left(-6\right)\right)[/tex]
[tex]y+3=\frac{2}{3}\left(x+6\right)[/tex]
Subtract 3 from both sides
[tex]y+3-3=\frac{2}{3}\left(x+6\right)-3[/tex]
[tex]y=\frac{2}{3}x+4-3[/tex]
[tex]y=\frac{2}{3}x+1[/tex]
comparing with the slope-intercept form y=mx+b
Here the slope = m = 2/3
Y-intercept b = 1
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
Given the line
[tex]y=\frac{2}{3}x+1[/tex]
at x = 0, y = 1
Thus, the point (0, 1) represents the y-intercept.
Hence, the y-intercept (0, 1) is on the same line.

What is the intermediate step in the form (x + a)2 = b as a result of completing the
square for the following equation?
x2 + 34 = 10x
Answer:
So the intermediate step in question is (x - 10)² = 66
Step-by-step explanation:
Let's find out:
x² + 34 = 10x
x² - 10x = -34
x² - 20x + 100 = 66
(x - 10)² = 66
x - 10 = ± √66
x = 10 ± √66
x ≈ 18.12, 1.88

Answer:
n=1, m=3, and p=-4
Step-by-step explanation:
Take the fourth root of both sides
so x^n*y^m*z^p=x*y^3*z^-4;
notice z has a negative exponent because it was in the denominator
therefore, n=1, m=3, and p=-4
Help me pleasee. Solve the system by substitution
Answer:
(3, - 2 )
Step-by-step explanation:
Given the 2 equations
4x - 2y = 16 → (1)
y = - 5x + 13 → (2)
Substitute y = - 5x + 13 into (1)
4x - 2(- 5x + 13) = 16 ← distribute and simplify left side
4x + 10x - 26 = 16
14x - 26 = 16 ( add 26 to both sides )
14x = 42 ( divide both sides by 14 )
x = 3
Substitute x = 3 into (2) for corresponding value of y
y = - 5(3) + 13 = - 15 + 13 = - 2
solution is (3, - 2 )

Look at the following numbers:
-7, 0, 7, 14
Which pair of numbers has a sum of 0?
Group of answer choices
0, 7
-7, 7
7, 14
-7, 14
Answer:
The correct answer is: -7, 7
Step-by-step explanation:
Given numbers are:
-7, 0, 7, 14
We have to check all pairs of numbers with respect to sum to check that which pair of numbers sums up to zero. So first of all, we will take -7 and will find its sum with other numbers.
So,
[tex]-7+0 = -7\\-7+7=0\\-7+14 = 7[/tex]
We can see that the sum of -7 and 7 is zero.
Hence,
The correct answer is: -7, 7
Your answer is B.) -7, 7
