Answer:
y = 6x + 17
Step-by-step explanation:
First you can find the slope:
m = (y2-y1) / (x2-x1)
m = (-7 - (-1)) / (-4 - (-3))
m = (-7 + 1) / (-4 + 3)
m = -6 / -1
m = 6
_______
Then we can plug what we know into the point-slope form:
y - y1 = m (x - x1)
(you can pick either one of the points to plug in as (x1, y1))
y - (-7) = 6 (x - (-4))
y + 7 = 6 (x + 4)
_______
Now we can change the point-slope form into slope-intercept form by solving for y:
y + 7 = 6 (x + 4)
y + 7 = 6x + 24
y = 6x + 17

Y=a|x-h|+k
11. how does the value of k affect the graph?
12. how does the value of h affect the graph?
13. how do the sign and absolute value of A affect the graph?
Step-by-step explanation:
Given the general form of the absolute value function, y = a|x - h| + k
11. How does the value of k affect the graph?The value of k determines how far up or down the parent function is translated. If k is positive, the function is translated k units up. If k is negative, the function is translated |k | units down.
12. How does the value of h affect the graph?The value of h determines how far left or right the parent function is translated. If h is positive, the function is translated h units to the right. If h is negative, the function is translated |h | units to the left.
13. How do the sign and absolute value of A affect the graph?The value of a determines whether the graph opens up or down.
If a is positive, the graph opens up.If a is negative, the graph opens down.The value of a also makes the parent function wider or narrower.
If 0 < a < 1, the graph is wider than the parent function.If a > 1, the graph is narrower than the parent function.PLEASE HELP WORTH 10

solve for a : 24a=8
simplify the answer as much as possible.
Answer:
a=1/3
Step-by-step explanation:
24a=8
Divide both sides by 24, and you will get a=8/24
Divide both the numerator and denominator by 4, and you will get 2/6, which is equivalent to 1/3.
Answer:
a = 1/3
Step-by-step explanation:
Divide both sides of the equation by the same term(24)
24a/24 and 8/24 = a = 1/3
Ryan spent a total of $40 at the grocery store. Of this amount, he spent $14 on fruit. What percentage of the total did he spend on fruit?
Answer:
35%
Step-by-step explanation:
ryan spent 14 out of his 40 dollars on fruit. so ryan spent 14/40 or 7/20 of his money.
to convert a fraction to a percentage, multiply by 100
so multiply 7/20 by 100 to get 35%
Answer:
35%
Step-by-step explanation:
Ryan spent $14 out of his $40 dollars on fruit. This is 14/40 = 35%

14 over 15 rounded to the nearest tenth
Answer:
0.9
Step-by-step explanation:
14/15 = 0.933333333 IF:
1. You first change it into a decimal by dividing the numerator by the denominator.
14 ÷ 15
2. You will get a recurring decimal.
0.933333333
3. The first digit after the decimal is in the position of the 'tenths'
0.9
4. You should use only two digits after the decimal to calculate
0.93
5. Since the number 3 is less than five, it will change into a zero and get eliminated.
∴ The answer will be = 0.9

Evaluate the expression when e=13 and f=16.
4(19+e2)+3f
Enter your answer as a mixed number in simplest form
Answer:
1 7/18
Step-by-step explanation:
I Had Also Taken The Test And It Was 1 7/18 In Mixed Numbers.
The expression 4(19 + e2) + 3f at e = 13 and f = 16 is 804.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, we have to Evaluate the expression 4(19 + e2) + 3f when e = 13 and
f = 16 is the same as replacing the numerical values of e and f in the expression
4(19 + e2) + 3f which is,
= 4(19 + 13²) + 3×16.
= 4(19 + 169) + 48.
= 4(189) + 48.
= 756 + 48.
= 804.

Find the value of arc s
Answer:
≈ 38.64 units
Step-by-step explanation:
The length of arc s is calculated as
circumference of circle × fraction of circle
The central angle subtended by arc s is 360° - 114° = 246° then
arc s = 2πr × [tex]\frac{246}{360}[/tex]
= 2π × 9 × [tex]\frac{41}{60}[/tex]
= 18π × [tex]\frac{41}{60}[/tex]

Find the volume of a right circular cone that has a height of 10.6 m and a base with a
diameter of 18.5 m. Round your answer to the nearest tenth of a cubic meter.
The volume of a right circular cone that has a height of 10.6 m and a base with a diameter of 18.5 m is,
V = 949.76cm³
What is 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;
Height of cone = 10.6 m
Diameter of cone = 18.5 m
Hence, We can solve for radius as;
= 18.5/2
= 9.25
We know that;
Volume of a right circular cone is,
V = 1/3(πr²h)
Here, r = 9.25, h = 10.6, π = 3.14,
Hence, We get;
V = 1/3(3.14)(9.25)²(10.6)
V = 1/3(3.14)(85.5625)(10.6)
V = 1/3(2847.86225)
V = 949.287417
V = 949.76cm³
Thus, The volume of a right circular cone that has a height of 10.6 m and a base with a diameter of 18.5 m is,
V = 949.76cm³
