f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. FYI: Different textbooks have different interpretations of the reference "standard form" of a quadratic function.
The standard form of a parabola is y=ax2++bx+c , where a≠0 . The vertex is the minimum or maximum point of a parabola. If a>0 , the vertex is the minimum point and the parabola opens upward. If a<0 , the vertex is the maximum point and the parabola opens downward.

Which of the following statements is true about the graph of the inequality y≤ax+b, where a≠0?
A. The graph of the inequality is a dashed line, and the shaded region is below the line.
B. The graph of the inequality is a solid line, and the shaded region is below the line.
C. The graph of the inequality is a solid line, and the shaded region is above the line.
D. The graph of the inequality is a dashed line, and the shaded region is above the line.
Answer:
The correct option is;
B. The graph of the inequality is a solid line, and the shaded region is below the line
Step-by-step explanation:
The given inequality is y ≤ ax + b, a ≠ 0
Therefore. the inequality is a straight line graph with a slope = a, and a y-intercept of b
Given that the inequality uses an equal to or lesser than sign, we have that the graph of the inequality is a solid line
Whereby the region of feasibility is the region below the value of the expression on the right of the inequality, the area below the straight line graph is the shade (feasible) region.

suppose BD bisects angel ABC. if angel ABD=2x+5 and angel DBC =x+23 what is angel ABC
Answer:
Bisect angle split an angle equally.
So,
ABD = DBC
2x+5 = x + 23
x = 23 - 5

Identify the equation in slope-intercept form for the line that contains points (3,−10) and (6,5).
Answer:
the answer is 5... 5- (-10) and 6-3 and divide the change by 15 and 3 and you'll get 5
Step-by-step explanation:
The linear function or equation in the slope-intercept form will be y = 5x - 25.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
The linear function is given as,
y = mx + c
Here, m is the slope while c is the y-intercept.
Slope m = (5 + 10)/(6 - 3)
m = 5
Put m = 5, (6,5)
5 = 5(6) + c
c = -25
Thus, y = 5x - 25
Hence "The linear function or equation in the slope-intercept form will be y = 5x - 25".

A party flyer has a surface area of 88 square inches. If the length of the paper is 11 inches, wha tis the width in inches?
Answer:
the width is 8 inches
Step-by-step explanation:
area=length x width
88=11(w)
w=8
Answer:
8
Step-by-step explanation:
A flyer is the shape of a rectangle ad its area uses the formula A = l*w. Since the area is 88 and the length is 11 inches, then 88 = 11*w. Solve for w.
88/11 = 11w/11
8=w
Determine whether the ordered pair (10, 4) is solution to the equation 3x - 5y = 10
O Yes, (10, 4) is a solution.
O No, (10, 4) is not a solution.
Given :
The ordered pair (10, 4) is solution to the equation 3x - 5y = 10.
To Find :
Which one is the solution and which is not.
Solution :
Two pairs are (10,4) and (4,10) :
Putting ( 10,4 ) in given equation, we get :
LHS = 3( 10 ) - 5( 4 ) = 30 - 20 = 10 = RHS
So, ( 10,4 ) is the solution of the equation.
Now, putting, ( 4, 10 ) in given equation, we get :
LHS = 3( 4 ) - 5( 10 ) = 12 - 50 = -38 ≠ RHS
Therefore, (10,4) is the solution and (4,10 ) is not the solution.
Hence, this is the required solution.
Answer: Yes, (10,4) is a solution

x=-2
Step-by-step explanation:
add 5 to get rid of the -5 and then -4 become 1 then multiply by 10 to get rid of the divide by 10 then 10 times 1 equals 10 so then you divide by negative 5 so now you have x=10÷-5 and that equals -2

Instructions: Find the measure of the indicated angle to the
nearest degree
Answer:
Required indicated angle is: 47°
Step-by-step explanation:
Given triangle is a right angled triangle
The side opposite to reference angle is perpendicular so,
Hypotenuse = 48
Perpendicular = 35
The trigonometric ratio of sine will be used as it involves hypotenuse and perpendicular.
Let y be the required angle
[tex]sin\ y = \frac{perpendicular}{hypotenuse}\\sin\ y = \frac{35}{48}\\sin\ y = 0.72916\\y = sin^{-1}\ (0.72916)\\y = 46.81..[/tex]
Rounding off to nearest degree,
y = 47°
Hence,
Required indicated angle is: 47°
.The ratio of tomatoes to red apples is 2:5. If there are 20 tomatoes, how many red apples are there
Answer:
8:20
Step-by-step explanation:
If there are 20 tomatoes there will be x:20 which means we need to know how many red apples there is.
So you ask yourself this how many times did you get from 5 to 20?
4 so you multiply 4 with the number of red apples which is 2 and you will get 8

What is the volume of a hemisphere with a radius of 39.4ft, rounded to the nearest tenth of a cubic foot?
Answer:
128099.5
Step-by-step explanation:
answers may vary to what the teacher wants as an answer but thats what i got according to delta math
The volume of a hemisphere with a radius of 39.4ft, rounded to the nearest tenth of a cubic foot is,
⇒ 122,325.97 cubic units
What is mean by Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Radius of hemisphere = 39.4 feet
Now, We know that;
The volume of a hemisphere = (2/3)πr³ cubic units.
Hence, We get;
The volume of a hemisphere = (2/3)π (39.4)³ cubic units.
= 2/3 × 3 × 61,162.98
= 122,325.97 cubic units
Thus, The volume of a hemisphere with a radius of 39.4ft, rounded to the nearest tenth of a cubic foot is,
⇒ 122,325.97 cubic units

Step-by-step explanation:
Write the following equation in slope-intercept form. - y + 6 = 0 y = - 6/5 y = + 6 y = 5/6
Answer:
y = +6
Step-by-step explanation:
-y + 6 = 0
Subtract 6 from both sides;
-y = -6
Divide both sides by -1

There are 12 squares and 16 triangles. What is the simplest ratio of squares to triangles?
Answer:
3 to 4
Step-by-step explanation:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 12 and 16 is 4
Divide both terms by the GCF, 4:
12 ÷ 4 = 3
16 ÷ 4 = 4
The ratio 12 : 16 can be reduced to lowest terms by dividing both terms by the GCF = 4 :
12 : 16 = 3 : 4
Therefore:
12 : 16 = 3 : 4
