son4ous [18]

Answer:

The number of apples bought was 7 and the number of pears bought was 4

Step-by-step explanation:

The correct question is

Thanh bought 11 pieces of fruit and spent $5.60. If apples cost $0.60 each and pears cost $0.35 each, how many of each kind of fruit did he buy?

Let

x ---->the number of apples bought

y ----> the number of pears bought

we know that

Thanh bought 11 pieces of fruit

$x+y=11$ ----> equation A

apples cost $0.60 each and pears cost $0.35 each and Thanh spent $5.60

$0.60x+0.35y=5.60$ ----> equation B

Solve the system of equations by graphing

Remember that the solution is the intersection point both graphs

Using a graphing tool

The solution is the point (7,4)

see the attached figure

therefore

The number of apples bought was 7 and the number of pears bought was 4

two points on the line are (-10,1) and (5,-5).if the coordinate of another point on the line is -3,what is the x-coordinate?

zlopas [31]

Answer:

x-coordinate = 0

Step-by-step explanation:

(-10,1) , (5,-5)

m = (y₂ - y₁)/(x₂ - x₁) = ( -5 - 1 ) / ( 5 - [-10] )

= -6 / ( 5 + 10)

= -6/15 = -2/5

y - y₁ = m (x - x₁)

y - 1 = (-2/5) ( x - [-10] )

y - 1 = (-2/5) ( x + 10 )

5 * (y -1) = -2 (x + 10)

5y - 5 = -2x -20

2x + 20 + 5y -5 = 0

2x + 5y + 15 = 0

Another point (a, -3) in on this line

2 * a + 5 * (-3) = -15

2a -15 = -15

2a = -15 +15

2a = 0

a = 0

x-coordinate = 0

I need help with math work!!

Akimi4 [234]

Answer:

(g-h)=x^2+5-8-x

=x^2-x-3

(g-h)(-9) means x= -9

x^2-x-3

=(-9)^2-(-9)-3

=81+9-3

=90-3

=87
