TIMED HURRY!! For the given equation, find the values of a, b, and c, determine the direction in which the parabola opens, and determine the y-intercept. Decide which table best illustrates these values for the equation: y = x squared + 7 x Table A a b c up or down y-intercept 1 7 0 up (0,0) Table B a b c up or down y-intercept 7 1 0 up (0,0) Table C a b c up or down y-intercept 7 1 0 down (0,0) Table D a b c up or down y-intercept 1 7 0 down (0,0) a. Table A c. Table C b. Table B d. Table D
Answer:
the answer is c
Step-by-step explanation:
We can see that Table A best illustrates the values for the equation.
The answer is (a) Table A.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
The given equation is y = x² + 7x.
We can determine the values of a, b, and c by comparing the equation to the standard form of a quadratic equation,
which is y = ax² + bx + c.
In this case,
a = 1, b = 7, and c = 0.
To determine the direction in which the parabola opens, we can look at the coefficient of the x² term, which is a.
Since a is positive, the parabola opens upwards.
The y-intercept is the point where the parabola intersects the y-axis.
To find it, we can set x = 0 in the equation:
y = 0² + 7(0) = 0
So the y-intercept is (0,0).
Thus,
We can see that Table A best illustrates the values for the equation.
The answer is (a) Table A.

Solve the equation: 315= 390- 25q
Answer:
q=3
Step-by-step explanation:
315=390-25q
390-25q=315
390-25q-390=315-390
-25q=-75
Divide both sides by 25
q=3
Answer: q = 3
Step-by-step explanation:
315 = 390 - 25Q
1. Minus 390 from both sides
-75 = =-25q
2. Divde both sides by -25 to get q by itself
3 = q or q = 3

What is the value of y in (1/2)x + 3 = (1/3)y - 2 if x = 28/3?
Answer:
y = 29
Step-by-step explanation:
x/2 + 3 = y/3 - 2
28/3 ÷ 2 = 14/3
14/3 + 9/3 = y/3 - 6/3
23/3 + 6/3 = y/3
29/3 = y/3 ∴ y = 29

Lucy Baker is analyzing demographic characteristics of the American Idol program. Previous studies indicate that the average viewer is 43 years old. May changes took place in the program and there are rumors the audience has changed. Mrs. Baker was tasked to find out . She randomly selects 100 people from the audience, and reports that the average age is 45 years. Assuming that variability in the ages of viewers is σ = 5 years, identify if Mrs. Baker's conclusion. She wants to accept a Type I error of .05.
Answer:
We conclude that the mean age of average viewer has changed
Step-by-step explanation:
H0 : μ = 43
H1 : μ > 43
The test statistic :
(xbar - μ) ÷ σ/sqrt(n)
Sample size, n = 100
xbar = 45 ; σ = 5
Test statistic :
(45 - 43) ÷ 5/sqrt(100)
2 ÷ 0.5 = 4
The Pvalue :
P(Z < 4) = 0.000032
Pvalue < α
0.000032 < 0.05 ; Hence, we reject the Null
We conclude that the mean age of average viewer has changed
Find the perimeter of quadrilateral ABCD. Round your answer to the nearest hundredth. A(3, 5) B(1, 3) C(3, -1) D(5, 3)
Answer:
Perimeter = 4(√2 + √5) units
Step-by-step explanation:
Given:
Quadrant of 4 points;
A(3, 5) B(1, 3) C(3, -1) D(5, 3)
Find:
Perimeter
Computation:
Distance = √(x1 - x2)² + (y1 - y2)²
Distance between AB = √(3 - 1)² + (5 - 3)²
Distance between AB = √4 + 4
Distance between AB = 2√2 units
Distance between BC = √(1 - 3)² + (3 + 1)²
Distance between BC = √4 + 16
Distance between BC = 2√5 units
Distance between CD = √(3 - 5)² + (-1 - 3)²
Distance between CD = √4 + 16
Distance between CD = 2√5 units
Distance between DA = √(5 - 3)² + (3 - 5)²
Distance between DA = √4 + 4
Distance between DA = 2√2 units
Perimeter = sum of all sides
Perimeter = 2√2 + 2√5 + 2√2 + 2√5
Perimeter = 4√2 + 4√5
Perimeter = 4(√2 + √5) units

Write the general variation equation
Find the constant of variation, k.
Write a variation equation relating x and y using the value of k found in b).
Find y when x = -5.
у
Answer:
y = -15
Step-by-step explanation:
Given that,
y varies directly as x i.e.
[tex]y\propto x\\\\y=kx[/tex]
Where
k is the constant of variation.
Put y = 12 and x = 4 to find k.
[tex]k=\dfrac{y}{x}\\\\k=\dfrac{12}{4}\\\\k=3[/tex]
Now put k = 3 and x = -5 and finding the value of y.
[tex]y=3\times -5\\\\y=-15[/tex]
So, the value of y is equal to -15.
Three friends all have ages that are consecutive integers. The sum of their
ages is 57. What is the age of the oldest friend?
Answer:
Friend C would be 20 years old
Step-by-step explanation:
Consecutive integers are integers that follow each other
In this case, we have three friends (let's call them A, B, and C) who's total age sum is 57:
A + B + C = 57
If Friend B is one year older than Friend A and Friend C is two years older than Friend A (or one year older than Friend B), then we write and solve for Friend A:
A + (A + 1) + (A + 2) = 57
3A + 3 = 57
3A = 54
A = 18
So if Friend A is 18 years old, then Friend B is 19 years old, and Friend C is 20 years old, making Friend C the oldest.
Answer:
20 years old
Step-by-step explanation:
3x + 3 = 57
3x = 54
x = 18
X + 2 = 18 + 2
Answer = 20 years old
