Each year, Andrea donates a total of $800 for scholarships at her local community college. This year, she wants the amount she donates for liberal arts to be three

times the amount she donates for scholarships for business. Determine the amount she will donate for each type of scholarship.

The equation is Andrea will donate $ for business scholarships and $ for liberal arts scholarships.

Answers

Answer:

The equation is [tex]L + B = \$800[/tex]

Andrea will donate $200 for business scholarships and $600 for liberal arts scholarships.

Step-by-step explanation:

Given

Represent Liberal Arts with L and Business with B

From the question, we have that:

[tex]L = 3 * B[/tex]

and

[tex]Total = \$800[/tex]

Required

Determine how much she donates for each

The total L + B is 800

i.e.

[tex]L + B = \$800[/tex]

Substitute 3 * B for L

[tex]3 * B + B = \$800[/tex]

[tex]3 B + B = \$800[/tex]

[tex]4B = \$800[/tex]

Solve for B

[tex]B =\$800/4[/tex]

[tex]B =\$200[/tex]

Recall that :

[tex]L = 3 * B[/tex]

[tex]L = 3 * \$200[/tex]

[tex]L = \$600[/tex]

Answers

Answer:

True

Step-by-step explanation:

7y and 8y are like terms, so you can add them together

True.

How? By combining like terms.

7y + 8y = what?

We keep the variable y and simply add the numbers.

7 + 8 = 15

We now include y in our answer.

So, 7y + 8y = 15y.

A high school football team scored 39 points in the game last night, with a combination of touchdowns (6 points each), extra points (1 point each), and field goals (3 points each).
The team make 1 more extra point than field goals, represented by the equation e=f+1, where e is the number of extra points and f is the number of field points scored.
They also scored five times as many points on touchdowns as field goals, represented by the equation 6t=15f, where t is the number of touchdowns and f is the number of field goals scored.
Write a system of equations representing this situation and use it to complete the statement.
The team scored __ touchdowns, __ extra points, and __ field goals.

Answers

Answer:

39=6t+3f+e

39=19f+1

5 touchdowns, 3 extra points, and 2 field goals.

Show that x + y : x - y= 3 : 2

Answers

Answer:

x + y : x - y = (5/2+1/2) : (5/2-1/2)

x + y : x - y = 3 : 2

Therefore,  x + y : x - y= 3 : 2 is proved.

Step-by-step explanation:

Given

x + y : x - y = 3 : 2

As

[tex]x + y = 3[/tex]

[tex]x - y = 2[/tex]

Solving to find x and y

[tex]\begin{bmatrix}x+y=3\\ x-y=2\end{bmatrix}[/tex]

[tex]x-y=2[/tex]

[tex]-[/tex]

[tex]\underline{x+y=3}[/tex]

[tex]-2y=-1[/tex]

[tex]\begin{bmatrix}x+y=3\\ -2y=-1\end{bmatrix}[/tex]

solve for y

[tex]-2y=-1[/tex]

Divide both sides by 2

[tex]\frac{-2y}{-2}=\frac{-1}{-2}[/tex]

[tex]y=\frac{1}{2}[/tex]

[tex]\mathrm{For\:}x+y=3\mathrm{\:plug\:in\:}y=\frac{1}{2}[/tex]

[tex]x+\frac{1}{2}=3[/tex]

[tex]x+\frac{1}{2}-\frac{1}{2}=3-\frac{1}{2}[/tex]

[tex]x=\frac{5}{2}[/tex]

so

[tex]x=\frac{5}{2},\:y=\frac{1}{2}[/tex]

Thus,

x + y : x - y = (5/2+1/2) : (5/2-1/2)

x + y : x - y = 3 : 2

Therefore,  x + y : x - y= 3 : 2 is proved.

Step-by-step explanation:

the equation was not the only way that could change in a single year of growth

we have:(x, y1)=(1,0)

(x2,y2)=(0,1)

then the equation of circle is

(x-1)(x-x2)+(y-y1)(y-y2)=0

=(x-1)(x-0)+(y-0)(y-1)=0

=x2-x+y2-y=0

=x2++y2-x-y=0.

Write an equation in slope-intercept form for the line with slope 6 and y-intercept -8 .

Answers

Answer:

y=6x-4

Step-by-step explanation:

The equation of line in the slope intercept form is y = 6x - 8 , where the slope of the line is m = 6

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the slope of the line m = 6

Let the y intercept of the line be = -8

Now , equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

Substituting the values in the equation , we get

y = 6x - 8   be equation (1)

Hence , the equation of line is y = 6x - 8
