Brianna jogs 15 minutes more on Sunday than Saturday. She jogged 26 minutes on Saturday.
a.
How many minutes does she jog on Sunday?
Answer:
41
Step-by-step explanation:
15+26=41
Answer:
41 minutes
Step-by-step explanation:
If she jogged 15 minutes more on Sunday than Saturday, we can find how many minutes she jogged on Sunday by adding 15 to Saturday's amount:
So, add 15 to 26:
15 + 26
= 41
So, she jogged 41 minutes on Sunday.
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]

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 product of 15 and a number X is -75. Write the equation, and solution for X.
Answer: [tex]x = -5[/tex]
Step-by-step explanation:
If a product of 15 and an unknown number equals -75 the equation should look like this:
[tex]15x = -75[/tex]
Now to solve for x:
1. [tex]\frac{15x}{15} = \frac{-75}{15}[/tex]
2. [tex]x = -5[/tex]
The solution for x is -5.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation. Equal treatment should be given to each party.
Given:
The product of 15 and a number X is -75.
So, the expression is
15x = -75
Now, divide 15 on both side
15x/15= -75/15
x= -5
Hence, the value of x is -5.

Answer:
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.

Y=2/3x+2-2x+3y=6
Answer:
answer for y=2/3x+2: y=2/3x+2
answer for -2x+3y=6: x=3/2y-3
pls give brainliest
Answer:
There are infinitely many solutions.
Step-by-step explanation:
There are infinitely many solutions because if you solve the equations, you will find that both of the equations are actually the same, so there is infinitely many solutions.
Showing that both equations are equal: y=2/3x+2 -2x+3y=6
y=2/3x+2 Multiply by 3 on both sides
3y=2x+6 Rearrange (-2x on both sides)
3y-2x=6 More rearrangement
-2x+3y=6 Now, if you look back at the second equation, you will see that they are both the same.
