Answer:

y= -2 and x= 2.

Step-by-step explanation:

(y=-3x+4)4

(y=4x-10)3

make the x's cancel out.

you get 7y=-14.

y=-2.

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.

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].

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

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

y = -x+ 84

y= x^2 + -6

750/100 X 7 = 52.50

52.50 X 3 = $157.50

Step-by-step explanation:

divide principal amount by 100 then multiply by interest percentage. this gave 52.50

now multiply the interest amount by number of years

in this case 3

52.50 X 3 = $157.50

Answer:

yes you did right answer

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​

A diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles.

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.
