"9 less than a number is
zero."
I need help
Answer:9 less than 9 is 0
Step-by-step explanation:
9-9=0
Answer:
9
Step-by-step explanation:
Less means minus, so basically X ( something ) - 9 is 0
X - 9 = 0
You add 9 on each side
X = 0 + 9
X = 9
Basically, all you're doing is the reverse, you start with 0 and do the opposite of taking away 9 which is adding nine so that you get the number:
0 + 9 = 9
Hence the number is 9

Determine the point and slope from the equation
y-4-5(x + 7)
point (-7.4) slope: -5
point (7.4) slope: -5
point (7.-4) slope: -5
To determine the point and slope from the given equation, we can rewrite the equation in the standard form of a linear equation: y = mx + b, where m is the slope and b is the y-intercept (the point at which the line crosses the y-axis).
In this case, the equation is already in the standard form, so we can immediately see that the slope is -5 and the y-intercept is (0, 4). This means that the point at which the line crosses the y-axis is (0, 4), and the slope of the line is -5.
Therefore, the correct answer is:
Point: (0, 4)
Slope: -5

b) If you sold 47 drinks, how many hot dogs did you sell?
You are running the concession stand for the basketball game. You sell hot dogs for $1.50 and drinks for $2.
a) an equation in a standard form that models this situation is
1.5H + 2D = 250
b) Hot dogs sold 104
What is the equation?Generally, a) Let H be the number of hot dogs sold and D be the number of drinks sold. The equation that models this situation is:
1.5H + 2D = 250
b) To find the number of hot dogs sold, we can solve the equation for H:
1.5H = 250 - 2D H = (250 - 2D) / 1.5
Substituting D = 47 into this equation gives us:
H = (250 - 2*47) / 1.5 H = (250 - 94) / 1.5 H = 156 / 1.5 H = 104

In the diagram, ∠4 ≅ ∠5 and SE — bisects
∠RSF. Find m∠1. Explain your reasoning.
Answer:
60°
Step-by-step explanation:
You want the measure of angle 1 in the given diagram.
Angle relationsTransversal TR creates corresponding angles 1 and 5, so those are congruent.
It is given that angles 4 and 5 are congruent.
Transversal SE creates alternate interior angles 2 and 4, so those are congruent.
Angle bisector SE creates angles 2 and 3 congruent.
Now we have ∠1≅∠5≅∠4≅∠2≅∠3.
Hence all of the angles are congruent to each other, and angle 1 is 1/3 of 180°.

A linear regression equation that represents the data set is y = -29.97x + 1048.80. Also, the number of new cases for 2026 is equal to 689 cases.
How to write the linear regression equation?In this scenario, the Year since 2014 (x) would be plotted on the x-axis of the scatterplot while the New cases (y) would be plotted on the x-axis of the scatterplot.
On the Excel sheet, you should right click on any data point on the scatterplot, select format trend line and then tick the box to display an equation for the linear regression (line of best fit) on the graph.
By critically observing the scatterplot (see attachment) which models the relationship given in the table, an equation for the linear regression is given by:
y = -29.97x + 1048.80
For 2026, the value of x is given by:
x = 2026 - 2014 = 12 years.
Now, we can determine the new cases for 2026:
y = -29.97(12) + 1048.80
y = -359.64 + 1048.80
y = 689.16 ≈ 689 cases.

A model car is 12 inches long. Using a scale of 3 inches : 4 feet ,how long is the actual car
The basic unit of length in the metric system is the meter. All units of length in the metric system are derived from the meter.
What is unit of length?Using measuring instruments like a ruler, measuring tape, etc., one can measure the length of any object. A ruler can be used to determine, for instance, how many inches a pencil is long. A feet scale can be used to gauge the height of each student in a class.The inch, foot, yard, and mile are the fundamental units of length and distance measurement in the English system. The rod, furlong, and chain are additional length units.Length of the car is 12 inches equal to 192 feet.
Given ,
3 inches : 4 feet
3 inches : 4*12
3 inches :48
1 inches : 16 feet
Length of the car is 12 inches = 12 * 16
Length of the car is 12 inches = 192 feet
The measurement or size of something from end to end is referred to as its length. To put it another way, it is the greater of the higher two or three dimensions of a geometric shape or object. For instance, a rectangle's length and width are its dimensions.In the metric system, the SI unit of length is a metre which is defined as: “The length of the path travelled by light in a vacuum within 1⁄299792458 seconds.”The SI unit of length is a metre (m). One metre (m) is divided into 100 equal parts called centimetre (cm). One centimetre (cm) has 10 equal parts called millimetre (mm). For measuring longer distances, we use a larger unit of length called, kilometre (km).To learn more about unit of length refer to:

OB. y = -2(x + 2)² - 5

In vertex form the equation of the parabola is [tex]y = -2(x+2)^{2} -5[/tex].
What is Vertex form if Parabola ?
When a graph crosses its symmetry axes, the vertex formula in mathematics may be used to get the vertex coordinate of a parabola. The vertex point is often represented by (h, k). We are aware that a parabola's conventional equation is y=ax2+bx+c. The vertex in this case should be near the base of the U-shaped curve if the coefficient of x2 is positive. The vertex should be at the peak of the U-shaped curve if the coefficient of x2 is negative. The standard form and vertex form of a parabola, as well as the vertex formula, will be covered in this article.
We are aware that the parabola's conventional form is y=ax2+bx+c.
So, y = a(x-h)2 + k is the vertex form of a parabola.
To determine a parabola's vertex, use the vertex formula. There are two methods for locating a parabola's vertex.
Vertex, (h, k) = (-b/2a, -D/4a)
Equation of the parabola,
y = [tex]-2x^{2} - 8x -13[/tex]
here ,
a = -2 , b = -8 and c = -13.
Therefore,
h = -b/2a = +8/-4 = -2 and,
k = -D/ 4a = [tex]-(b^{2} - 4ac)/4a[/tex] = -(64 - 104)/-8 = -40/8 = -5
So, the coordinate of vertex is (-2, -5)
So the vertex form of equation of parabola is
[tex]y = a(x-h)^{2} + k[/tex]
⇒ [tex]y = a(x+2)^{2} -5[/tex]
⇒ [tex]y = ax^{2} + 4ax +4a -5[/tex]
Equating this equation with equation pf parabola we get a = -2
So, in vertex form the equation of the parabola is [tex]y = -2(x+2)^{2} -5[/tex].

a. Which account statement is incorrect?
b. What may have been the bank's error?
The account statement for Account B is incorrect.
What is simple rate of interest?
Simple rate of interest is a type of interest calculation where interest is calculated only on the principal amount of a loan. Simple interest is calculated periodically, usually monthly or annually, as a fixed percentage of the principal. It is different from compound interest, which applies interest to both the principal and the accumulated interest. It is simpler to calculate than compound interest, and is generally used for short-term loans.
Given: Account A: $100, 3.4% and Account B: $300, 1.8%
We know, Simple Interest = Principal × Rate × Time
Interest for Account B = $300 × 1.8%
