Will the border line of the graph of y < - x2 + 4x + 5 be a solid line or a broken
line?
Is the point (0,0) part of the solution of y<-x2 +4x+5
Step-by-step explanation:
When the inequality uses < or >, it is a broken line.
For the point (0, 0) it means that x = 0 and y = 0.
Since (0) < (0)² + 4(0) + 5 is true, the point is part of the solution.
Yes, the point (0,0) is part of the solution of y < - x² + 4x + 5.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
To determine the border line of the graph of y < - x² + 4x + 5
A broken line results from the inequality using < or >.
x and y are both equal to zero at the coordinates (0, 0).
Substitute the values of x = 0 nad y = 0 in the inequality y < - x² + 4x + 5
So, (0) < (0)² + 4(0) + 5
Since (0) < (0)² + 4(0) + 5 is valid,
Thus, the coordinates (0, 0) are part of the solution.

A student borrows a total of $5400 in student loan from two lenders. Bank One charges 4.3% simple
interest and Bank Two charges 5.9% simple interest. She is not required to pay off the principal for 3
years. However, at the end of three years, she will owe a total of $888.60 for interest from both loans.
How much did she borrow from Bank One?
non
9514 1404 393
Answer:
$1400
Step-by-step explanation:
Let x represent the amount borrowed from Bank 1. For each loan, the interest is given by I=Prt, where P is the principal borrowed at rate r for t years.
Then the total interest over 3 years is ...
3(4.3%·x +5.9%(5400 -x)) = 888.60
-1.6%·x +318.60 = 296.20 . . . . . . . . . . . divide by 3, simplify
-1.6%·x = -22.40 . . . . . . . . . . . subtract 318.60
x = 22.40/0.016 = 1400
The student borrowed $1400 from Bank 1.

Ronnie records the number of chirps per minute (x) that crickets make at different temperatures(Y ) in degree Fahrenheit. he determines that the association is linear and that the line of best fit is Y=1/6x+60.what is the interpretation of the slope and y intercept of this question?
Answer:
Step-by-step explanation:
Given
[tex]y = \frac{1}{6}x + 60[/tex]
Required
Interpret the slope and y intercept
The general form of an equation is:
[tex]y = mx + b[/tex]
Where
[tex]m=slope[/tex]
[tex]b = y\ intercept[/tex]
By comparison
[tex]m = \frac{1}{6}[/tex]
[tex]b = 60[/tex]
Interpretation:
Slope represents rate and y intercept represents the number of chirps at time 0.
So, the interpretations are:
Slope: The cricket chirps at a rate of [tex]\frac{1}{6}[/tex] chirps per minute
y intercept: The initial number of chirps is 60

Step-by-step explanation:
Normally, we make use of reciprocal pronouns in cases where each of two or more subjects are acting in the same manner towards one another. For example, X is talking to Y, and Y is talking to Z.
Thus, the subjects in question must be the same objects for them to be able to relate in the same way.

Gia researches online that her car is worth $3,000. She hopes to sell it for 85% of that value, but she wants to get at least 70%. She ends up selling it for $1,800. Did she get what she wanted? (Give both equations and solutions. Then answer the question of did she get what she wanted)
Answer:
she did not get at least 2100 and definitely not 85% of the worth
Step-by-step explanation:
3000*0.85=2550
3000*0.7=2100
Answer:
Gia hoped to sell it for $2,550, but wanted at least $2,100. Because it sold for $1,800, she did not get what she hoped and/or wanted.
Step-by-step explanation:
85% of $3,000 can be solved by moving the decimal two places to the left and multiplying: 85.0% becomes 0.85. So, we multiply 0.85x3,000=$2,550.
We do the same thing to figure out 70% of $3,000. Again, solving it by moving the decimal two places to the left and multiplying: 70.0% becomes 0.70. So, we multiply 0.70x3,000=$2,100.
write the x and y coordinate (in the second and third column, respectively) of dilation of quadrilateral ABCD with vertices A(1,1), B(2,2), C(4,1) and d(2,-1). Use a scale factor of 2
Answer:
The coordinates of the dillated vertices are [tex]A'(x,y) = (2,2)[/tex], [tex]B'(x,y) = (4,4)[/tex], [tex]C'(x,y) = (8,2)[/tex] and [tex]D'(x,y) = (4,-2)[/tex].
Step-by-step explanation:
From Linear Algebra, we define dilation by the following equation:
[tex]P'(x,y) = O(x,y) + k\cdot [P(x,y)-O(x,y)][/tex] (1)
Where:
[tex]O(x,y)[/tex] - Center of dilation, dimensionless.
[tex]P(x,y)[/tex] - Original point, dimensionless.
[tex]k[/tex] - Scale factor, dimensionless.
[tex]P'(x,y)[/tex] - Dilated point, dimensionless.
If we know that [tex]O(x,y) = (0, 0)[/tex], [tex]k = 2[/tex], [tex]A(x,y) = (1,1)[/tex], [tex]B(x,y) = (2,2)[/tex], [tex]C(x,y) = (4,1)[/tex] and [tex]D(x,y) = (2,-1)[/tex], then the dilated points are, respectively:
Point A
[tex]A'(x,y) = O(x,y) + k\cdot [A(x,y)-O(x,y)][/tex] (2)
[tex]A'(x,y) = (0,0) + 2\cdot [(1,1)-(0,0)][/tex]
[tex]A'(x,y) = (2,2)[/tex]
Point B
[tex]B'(x,y) = O(x,y) + k\cdot [B(x,y)-O(x,y)][/tex] (3)
[tex]B'(x,y) = (0,0) + 2\cdot [(2,2)-(0,0)][/tex]
[tex]B'(x,y) = (4,4)[/tex]
Point C
[tex]C'(x,y) = O(x,y) + k\cdot [C(x,y)-O(x,y)][/tex]
[tex]C'(x,y) = (0,0) + 2\cdot [(4,1)-(0,0)][/tex]
[tex]C'(x,y) = (8,2)[/tex]
Point D
[tex]D'(x,y) = O(x,y) + k\cdot [D(x,y)-O(x,y)][/tex]
[tex]D'(x,y) = (0,0) + 2\cdot [(2,-1)-(0,0)][/tex]
[tex]D'(x,y) = (4,-2)[/tex]
The coordinates of the dillated vertices are [tex]A'(x,y) = (2,2)[/tex], [tex]B'(x,y) = (4,4)[/tex], [tex]C'(x,y) = (8,2)[/tex] and [tex]D'(x,y) = (4,-2)[/tex].

4. Determine the magnitude and direction of the vector v = <5, -6>.
f. 11, NE
g. 61, SE
h. 111, NE
j. V61, SE
Answer:
The magnitude of vector is:
[tex]\left|\begin{pmatrix}5&-6\end{pmatrix}\right|=\sqrt{61}[/tex]
v = <5, -6> means the vector has x-coordinate x = 5 and y-coordinate y = -6, so the vector v = <5, -6> is heading towards SE.
Thus, option ( j ) is correct.
i.e. [tex]\sqrt{61},\:SE[/tex]
Step-by-step explanation:
Given the vector
v = <5, -6>
Determining the magnitude of the vector
To find a magnitude of a vector v = (a, b) we use the formula
[tex]||v||\:=\:\sqrt{a^2+b^2}[/tex]
Magnitude of the vector is basically termed as the length of the vector, which is denoted by
[tex]|\left(5,\:-6\right)|=\sqrt{\left(5\right)^2+\left(-6\right)^2}[/tex]
[tex]=\sqrt{5^2+6^2}[/tex]
[tex]=\sqrt{25+36}[/tex]
[tex]=\sqrt{61}[/tex]
Thus, the magnitude of vector is:
[tex]\left|\begin{pmatrix}5&-6\end{pmatrix}\right|=\sqrt{61}[/tex]
As the vector v = <5, -6> lies in 4th quadrant.
v = <5, -6> means the vector has x-coordinate x = 5 and y-coordinate y = -6, so the vector v = <5, -6> is heading towards SE.
Thus, option ( j ) is correct.
i.e. [tex]\sqrt{61},\:SE[/tex]

Solve each percent equation. Remember "of" means multiply and "is" means equal.
At your school, 74% of students bought their lunch at the cafeteria. There are
1250 students in the school. How many students bought their lunch?
925
students who brought their lunch. YUM!!
Answer
925 students brought their lunch.
Explanation
First let's rewrite the equation.
You know that "of" means multiply and "is" means equal.
Okay, so let's break it down.
The question says, "At your school, 74% of students brought their lunch at the cafeteria. There are 1250 students in the school."
This means that 74% of 1250 students brought their lunch at the cafeteria.
You are trying to find how many students brought their lunch. This will be x.
So the equation would be this.
74% × 1250 = x
74% is 0.74.
0.74 × 1250 = x
0.74 × 1250 = 925
So 925 students brought their lunch.

⟨1.00, 1.73⟩
⟨1.73, 1.00⟩
Answer:
C
Step-by-step explanation:
edge 2021
The required coordinates of Amy's position are (1.00, 1.73).
Amys walk 2 miles 60° northeast from her house. Vector coordinates to be determined.
Coordinate is defined as the abscissa and ordinate of the x-axis and y-axis respectively.
Amy walk 2 miles on 60° northeast, from origin.
x coordinate = 2cos60
= 2 * 1/2
= 1
y coordinate = 2sin60
= 2*√3/2
= 1.73
Thus, the required coordinates of Amy's position are (1.00, 1.73).
