Answer:
A) y= -1/4x + 21/16
Step-by-step explanation:
y-1= -1/4(x + (-5/4))
y= -1/4x - 5/4+1
y= -1/4x + 21/16
Answer:
A) y= -1/4x + 21/16
Step-by-step explanation:
y-1= -1/4(x + (-5/4))
y= -1/4x - 5/4+1
y= -1/4x + 21/16

A field goal kicker makes 84% of the field goals he attempts he has attempted 50 field goals this season how many goals hs he made
Answer:
He has made 42 field goals this season
Step-by-step explanation:
To find x% of number y, multiply y by [tex]\frac{x}{100}[/tex] ⇒ [tex]\frac{x}{100}[/tex] × y
∵ A field goal kicker makes 84% of the field goals he attempts
→ That means he makes 84% of his total attempts
∵ He has attempted 50 field goals this season
→ That means his total attempts is 50 field goals
∴ He makes 84% of 50 field goals
∵ 84% = 84 ÷ 100 = 0.84
∴ He makes 0.84 of 50
∵ He makes = 0.84 × 50
∴ He makes = 42 field goals
∴ He has made 42 field goals this season

The formula h=30+40t-5t^2 can be used to find the height h, in meters, of an object shot upward from the top of a building 30 m above the ground at the initial speed of 40 mps, after t seconds. How much higher above the ground is the object after 4 seconds than 2?
Answer:
20m
Step-by-step explanation:
Given the formula that modelled the height given as;
h=30+40t-5t^2
At t = 4s
h=30+40(4)-5(4)^2
h = 30+160-80
h = 160-60
h = 110m
At t = 2s
h=30+40(2)-5(2)^2
h=30+80-20
h = 110-20
h= 90m
Difference in height = 110-90 = 20m
Hence the height is 20m higher above the ground at 4s than at 2s
The rate at which crickets chirp is a linear function of
temperature. At 60°F they chirp 74 times per minute.
At 72º they chirp 120 times per minute.
a.) Write an equation in slope intercept form that
represents this function.
b.)Predict the number of chirps per minute when the
temperature is 64º.
Answer:
a) [tex]y=\frac{23}{6} x-156[/tex]
b) [tex]\frac{268}{3}[/tex]
Step-by-step explanation:
Formulas for linear equations:
Slope-intercept: [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept
Point-slope: [tex]y-y_1=m(x-x_1)[/tex], where (x₁, y₁) is a point on the function and m is the slope.
a) We are given two points. If you're given two points (x₁, y₁) and (x₂, y₂), the slope m is given by the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Let's mark the temperature on the x-axis, and the number of chirps per minute on the y-axis. So, we have the following points: (60, 74), and (72, 120). Calculating the slope m between these two points:
[tex]m=\frac{120-74}{72-60}[/tex]
[tex]m=\frac{23}{6}[/tex]
Since we have the x and y coordinates of a point on the function, we can write an equation in point-slope form, which will help us to find the y-intercept. We need the y-intercept in order to write the slope intercept form of the equation. We will use the point (60, 74) here, although you can also use (72, 120) if you want.
Point-slope form equation of the linear function:
[tex]y-74=\frac{23}{6} (x-60)[/tex]
Now that we have the point-slope equation of the function, we can find the y-intercept. The y-intercept is the point on the function where the graph crosses the y-axis (when the x-value is 0). So, we plug in 0 for x into the equation and solve for y:
[tex]y-74=\frac{23}{6} (0-60)[/tex]
[tex]y=-230+74[/tex]
[tex]y=-156[/tex]
Now that we have the y-intercept value of the function, we can write an equation in slope-intercept form:
[tex]y=\frac{23}{6} x-156[/tex]
b) Since we marked the temperature on the x-axis, we can just plug in the number 64 as the x-value into the equation we have. y will be the number of chirps per minute when the temperature is 64º.
[tex]y=(\frac{23}{6} *64)-156[/tex]
[tex]y=\frac{736}{3} - \frac{468}{3}[/tex]
[tex]y=\frac{268}{3}[/tex]

What is the opposite reciprocal of 1/6?
A.6
B.-6
C.1/6
D.-1/6
Answer:
A. 6
Step-by-step explanation:
The reciprocal is the fraction flipped
1/6 would become 6/1
6/1 is basically 6
(You said the opposite reciprocal so I don't know if you meant the oppisite of the reciprocal but. . . . oh well. If you did mean that, then the answer would be C. 1/6)
Hope this helps :)
Need help pls I don’t really remember functions if anyone could pls help that would be great pls and thank you.

(6x – 2) + (–x + 5) please help it is homework
Answer:
Step-by-step explanation:
You open the brackets;(6x-2)+ (-x+5)
6x-2-x+5
After Opening the brackets you group like terms;6x-x-2+5
•After grouping you proceed to simplify;
6x-x is going to be;
5x
•And then -2+5 is going to be positive 3 it's just like subtracting 2 from 5
Which is going to be;
5x+3
After you are done with this that's the final answer

The sum of 2 times a number and 8 is 7
Answer:
The number is -1/2
Step-by-step explanation:
Let x be the number
2x+8 = 7
Subtract 8 from each side
2x+8-8 = 7-8
2x = -1
Divide each side by 2
2x/2 =-1/2
x = -1/2
The number is -1/2
Answer:
2x + 8 = 7
x = -1/2
Step-by-step explanation:
"a number" can be signified by a variable.
So 2 times a number would give you 2x
And 8 would mean to add 8.
Is 7 means the end result is 7.
So 2x + 8 = 7
x = -1/2

Hebrew National since the cost is only 0.73
Step-by-step explanation:
First we need to identify the cost of each hotdog for each brand. I'll go by in order.
Ball Park:
We know that it cost $6.95 and it's 8 dogs for each one. Meaning all we have to do is divide the price by the amount of hot dogs.
"Price/Hotdogs per package"
In order
6.95/8=0.86875 or 0.87
8.20/10=0.82
7.35/8=0.91875 or 0.92
17.50/24=0.7291666 or 0.73
Since we're dealing with currency we would most likely round it by the nearest hundredth so the true answer would be $0.87.
Use this formula that I made for this question for any other questions.

A kid traveled a distance of 9 km by bike, and then walked a distance of km.
a.Find the total distance traveled in terms of
b. If the total distance was less than 30 km, form an inequality in , and
then solve it!
Answer:
Step-by-step explanation:
The question is incomplete. Here is the complete question;
A kid traveled a distance of 9 km by bike, and then walked a distance of x km.
a.Find the total distance traveled in terms of x
b. If the total distance was less than 30 km, form an inequality in x, and
then solve it!
a) Total distance = distance travelled by bike + distance walked
Total distance = 9km + xkm
Total distance = (9+x)km
b) If the total distance was less than 30 km, the inequality representing this is;
9+x < 30
Subtract 9 from both sides;
9+x-9 < 30-9
x < 21
hence the solution to the inequality is x< 21
