Answer:
a=29/42
Step-by-step explanation:
6a-1÷7=4
first write the division as a fraction
6a-1/7=4
add 1/7 to each side
6a=4+1/7
which is equal to
6a=29/7
divide both sides by 6
a=29/42
the graph of y=f(x) is shown. a. estimate the turning point of the graph
Answer:
a) The location of the turning point is approximately [tex]V(x,y) = (-0.25, -2,1)[/tex].
b) Roots are approximately [tex]x_{1} \approx -1.3[/tex] and [tex]x_{2} \approx 0.8[/tex].
c) [tex]f(1.5) \approx 4[/tex]
Step-by-step explanation:
a) The figure presents the graphic of a parabola, that is, a second order polynomial, with an absolute minimum (vertex). The turning point of the graphic, that is, the point in which behavior of the curve changes, is the vertex. Hence, the location of the turning point is approximately [tex]V(x,y) = (-0.25, -2,1)[/tex]
b) According to the Quadratic Formula, second-order polynomials can have either two real roots or two conjugated complex roots. In this case, we have two real roots. A root corresponds with the point of the curve that passes through x-axis. In this case, roots are approximately [tex]x_{1} \approx -1.3[/tex] and [tex]x_{2} \approx 0.8[/tex].
c) [tex]f(1.5)[/tex] is the function evaluated at [tex]x = 1.5[/tex], that is, the value on y-axis associated with [tex]x = 1.5[/tex]. Lastly, we conclude that [tex]f(1.5) \approx 4[/tex].
which graph represents y=3x+2
Step-by-step explanation:
The general form of a straight line is y = mx + c, where m is the line's slope and c is the y-intercept.
For y = 3x + 2, the slope is positive 3 and the y-intercept is 2. The line should rise up and pass through the point (0, 2).
We are between Options B and C.
In Graph B, the line raises by 4 units for every 2 units across. Hence its slope is 4/2 = 2.
In Graph C, the line raises by 3 units for every 1 unit across. Hence its slope is 3/1 = 3.
Since we want 3 as the slope,
The answer is Option C.
The graph C represents y=3x+2

Answer:
the equation that has the same solution as the given expression is
m + 7.28 = 18.28
Step-by-step explanation:
Given expression;
0.2m = 2.20
To solve for m, divide both sides by 0.2
[tex]\frac{0.2 m}{0.2} = \frac{2.2}{0.2} \\\\m = 11[/tex]
From the given options, the equation that has the same solution as the given expression is m + 7.28 = 18.28
Solve the equation to confirm as follows;
m + 7.28 = 18.28
collect like terms
m = 18.28 - 7.28
m = 11
so my brother asked another question. He asked what is the rectangular room measures 224 square feet. One side of the room is 14 feet long. what is the perimeter of the room? how the question goes. (the rectangular room measures 224 square feet. One side of the room is 14 feet long. what is the perimeter os the room?
Answer:
The perimeter of the room is 60 feet.
Step-by-step explanation:
If the area of the room is 224 square feet, and one side is 14 feet, then the other side is 224/14 feet, or 16 feet.
This gives us the dimensions of the room, 14 x 16.
From this, we can calculate the perimeter, which would be 2(14+16), or 60.
Let me know if this helps!
Answer:
Step-by-step explanation:
The perimeter of the room is 60
The sum of two numbers is 84. The square of the first number is 6 more than the second number
Write a system of equations to find the value of x the first number, and y, the second number.
y = x2 +
Answer:
[tex]x + y = 84[/tex]
[tex]x^2 = 6 + y[/tex]
Step-by-step explanation:
Given
x = First Number
y = Second Number
Required
Write a system of equations
Sum is 84
This is represented as:
[tex]x + y = 84[/tex]
Square of first is 6 more than the second
This is represented as:
[tex]x^2 = 6 + y[/tex]
Hence, the equations are:
[tex]x + y = 84[/tex]
[tex]x^2 = 6 + y[/tex]
Answer: for plato users

Miss Guydan and her friend Alyssa are collecting food for the local food bank. Their goal is to collect 2100 pounds of food. They start with 400 pounds of food donated by a local grocery store. Their goal is to collect 25 pounds of food per day. Write an equation that represent this situation. Define your variables.
Answer: Required equation: 400+25x = 2100
Variable: x = Number of days to donate 2100 pounds.
Step-by-step explanation:
Let x = Number of days.
y = Total pounds of food donated in x days.
Given: Initial amount of food = 400 pounds
Pounds of food donated per day = 25
Total food = Initial amount of food + (Pounds of food donated per day ) (Number of days)
y = 400+25x
Their goal is to collect 2100 pounds.
2100 = 400+25x [Substitute y= 2100]
Required equation: 400+25x = 2100
Variable: x = Number of days.
