Answer: x = 8/1681
Step-by-step explanation:
select the equation represented by the graph
Answer:
b) y = -2/3 + 1
Step-by-step explanation:
The format for the equation is y = mx + b
(m is the slope, and b is the y intercept)
Slope is rise over run (the units the line moves up and the units the line moves to the right)
In this case, the slope is: -2/3 because it goes down 2 and to the right 3.
The y intercept is 1.
This makes our equation:
y = -2/3 + 1

helpp!! ill give brainliest! just explain a little at least
Answer:
(3,7)
Step-by-step explanation:
A function is a relation in which the members of the domain (x-values) DO NOT repeat. So, for every x-value there is only one y-value that corresponds to it. y-values can be repeated.

Answer:
The answer is y=-x+4 and y=-3x+2
Step-by-step explanation:
Answer:
y = x + 4 and y = 3x + 2
Step-by-step explanation:
Both of the lines slopes are positive, and for the equation of y = 3x + 2, the slope is 3 rather than [tex]\frac{1}{3}[/tex] because it goes up 3 then to the right 1 rather than up 1 and to the right 3.
find a number that is exactly halfway between 1 and 27
Answer:
14
Step-by-step explanation:
A number that is exactly halfway between 1 and 27 is the middle number
In other words, we want to find the median between 1 and 27
Median = (x + y) / 2
Let
x = 1
y = 27
Median = (x + y) / 2
= (1 + 27) / 2
= 28/2
= 14
Therefore, the number between 1 and 27 is 14

A store is having a sale on walnuts and chocolate chips. For 4 pounds of walnuts and 8 pounds of chocolate chips, the total cost is $25. For 2 pounds of walnuts and 3 pounds of chocolate chips, the total cost is $10. Find the cost for each pound of walnuts and each pound of chocolate chips.
Answer:
The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50
Step-by-step explanation:
Let,
x be the price per pound of walnuts
y be the price per pound of chocolate chips
According to given statement,
4x+8y=25 Eqn 1
2x+3y=10 Eqn 2
Multiplying Eqn 2 by 2
2(2x+3y=10)
4x+6y=20 Eqn 3
Subtracting Eqn 3 from Eqn 1
(4x+8y)-(4x+6y)=25-20
4x+8y-4x-6y=5
2y=5
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{5}{2}\\y=2.50[/tex]
Putting y=2.50 in Eqn 2
2x+3(2.50)=10
2x+7.50=10
2x=10-7.50
2x=2.50
Dividing both sides by 2
[tex]\frac{2x}{2}=\frac{2.50}{2}\\x=1.25[/tex]
Hence,
The cost of each pound of walnuts is $1.25 and each pound of chocolate chips is $2.50

Prove that sin²a + cos²a = 1 and = [tex]\frac{1}{cos^{2}a }[/tex] + tan²a (a not alpha)
Answer:
[tex]\frac{1}{cos^2a }= tan^2 a[/tex]
Step-by-step explanation:
Explanation:-
Given sin²a + cos²a = 1
and
[tex]\frac{1}{cos^{2} a} \\= \frac{sin^2a+cos^2a}{cos^2a} \\ \\\\ = \frac{sin^2a}{cos^2a} +\frac{cos^2a}{cos^2a}[/tex]
= tan²a + 1

6(3x - 5) - 7x = 25
Answer:
Step 1: Simplify both sides of the equation.
6(3x−5)−7x=25
(6)(3x)+(6)(−5)+−7x=25(Distribute)
18x+−30+−7x=25
(18x+−7x)+(−30)=25(Combine Like Terms)
11x+−30=25
11x−30=25
Step 2: Add 30 to both sides.
11x−30+30=25+30
11x=55
Step 3: Divide both sides by 11.
x=5
Step-by-step explanation:
The solution to the equation is x = 5.
To solve the equation 6(3x - 5) - 7x = 25, we need to simplify and isolate the variable x. Let's break it down step by step:
Distribute the 6 to the terms inside the parentheses:
18x - 30 - 7x = 25
Combine like terms on the left side of the equation:
(18x - 7x) - 30 = 25
11x - 30 = 25
Move the constant term to the right side by adding 30 to both sides:
11x = 25 + 30
11x = 55
Finally, isolate x by dividing both sides of the equation by 11:
x = 55 / 11
x = 5
Hence, the solution to the equation is x = 5. By simplifying and applying algebraic operations, we find that when x is equal to 5, the equation 6(3x - 5) - 7x = 25 holds true.

3 Select the correct answer. The variable y varles directly as x. When x = 20, y= 12. What is the value of y when x= 15?
А. 7 B. 9 C. 18 D. 25
Answer:
B.9
Step-by-step explanation:
What I did is I used ratio.
20:12
15:X
Cross multiply:15x12
Answer:180
The answer you get divided by 20.
180/20=9.
Answer:
B
Step-by-step explanation:
Given y varies directly as x, then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition when x = 20, y = 12, then
12 = 20k ( divide both sides by 20 )
k = [tex]\frac{12}{20}[/tex] = [tex]\frac{3}{5}[/tex]
y = [tex]\frac{3}{5}[/tex] x ← equation of variation
When x = 15, then
y = [tex]\frac{3}{5}[/tex] × 15 = 9

a bakery uses flour at a rate of 1/3 pounds each minute. at approximately what rate does the bakery use flour, in pounds per day
Answer:
I'm pretty sure the bakery uses 480 pounds per day
Step-by-step explanation:
You would multiply 1/3 by 60, which is 60 minutes an hour, and that gives you 20 which you would then multiply 20 by 24, which is 24 hours a day, which would then give you 480 pounds of flour per day.
Answer:
480 pounds
Step-by-step explanation:
because 1/3 times 60 is 20 and that is 20 pound /a hour then multiply it by 24
because there are 24 hours a day

1.It is given that h(x) = 2x − 5. Find h(4)
2.It is given that f(x) = 5x + 2. Find f –1(-3).
Answer:
h(4) = 3
f-1(-3) = - 1
Step-by-step explanation:
One
h(x) = 2x - 5
h(4) = 2*4 - 5
h(4) = 8 - 5
h(4) = 3
Two
Let y = f(x)
y = 5x + 2 Interchange x and y
x = 5y + 2 Subtract 2 from both sides
(x - 2) = 5y Divide by 5
(x - 2)/5 = y
but y = f'(x)
so f(x) = (x - 2)/5
f-1(-3) = (-3 - 2) / 5
f-1(-3) = -5/5
f-1(-3) = - 1
