What is the x intercept of the line 6x-3y=24

Archy [21]

At x intercept , y = 0 so we have

6x - 3(0) = 24

6x = 24

x = 4 Answer

Together, teammates Pedro and Ricky got 2677 base hits last season. Pedro had 285 more hits than Ricky. How many hits did each

abruzzese [7]

So basically, you subtract (2677-285 = 2392) then you divide by 2 (2392/2=1196) so Ricky has 1196 and Pedro has 1481

ANSWER CORRECTLY AND IF YOU DONT KNOW IT JUST DONT SAY ANYTHING

arlik [135]

9514 1404 393

Answer:

A. 40, dollars added per day to the bank account

B. y -600 = 40(x -0); y = 40x +600; 40x -y = -600

C. f(x) = 40x +600

D. $880

Step-by-step explanation:

A. The slope is given by the formula ...

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

m = (720 -600)/(3 -0) = 120/3

m = 40

The bank account is increasing at the rate of $40 per day.

__

B. Point-slope form is ...

y -k = m(x -h) . . . . . line with slope m through point (h, k)

Using the first point, we have (h, k) = (0, 600) and m = 40.

y -600 = 40(x -0)

Slope-intercept form is ...

y = mx +b . . . . . . line with slope m and y-intercept b

The first point tells us the y-intercept is b=600, so the equation is ...

y = 40x +600

Standard form is ...

ax + by = c . . . . . . . a > 0, and a, b, c mutually prime

This form can be obtained by subtracting y from the point-slope form.

40x -y = -600

__

C. Replacing y with f(x) in the slope-intercept form gets the desired equation.

f(x) = 40x +600

__

D. The table shows the balance after 6 days. The balance increases $40 each day, so the balance after 7 days is ...

$840 +40 = $880 . . . . balance after 7 days

Help will mark brainlist if it correct If each edge of a cube is increased by 2 inches, the

Anastasy [175]

Answer:

D. sum of these edges is increased by 24 inches -- True

Step-by-step explanation:

Given a cube and its edge is increased by 2 inches.

To study the effect of this increase in the Volume, area of each face, diagonal and sum of edges.

Solution:

Let the side of original cube = a inches.

Formula for volume of cube:

$V =side^3 = a^3$

If the side is increased by 2 inches, the side becomes (a+2) inches.

So, new volume, $V' = (a+2)^3$

Using the formula:

$(x+y)^3 =x^3+y^3+3xy(x+y)$

$V' = (a+2)^3 = a^3+8+3\times 2 \times a(a+2)=a^3+8+6a(a+2)$

So, $V' = V + 8+6a(a+2)$

Volume increased by 8+6a(a+2) [which is not equal to 8]

So, statement is false:

A. volume is increased by 8 cubic inches -- False

Each face in a cube is a square.

Area of each face, A = $side^2 = a^2$

New area, A' = $(a+2)^2$

Using the formula: $(x+y)^2 =x^2+y^2+2xy$

$A' = a^2+4+4a$

Area increased by 4+4a [which is not equal to 4 sq inches]

B. area of each face is increased by 4 square inches -- False

Diagonal of each face = $a\sqrt2$

Increase of 2 in the edge:

New diagonal = $(a+2)\sqrt2 = a\sqrt2+2\sqrt2$

So, increase of $2\sqrt2$ not 2.

C. diagonals of each face is increased by 2 inches -- False

There are 12 number of edges in a square.

So sum of all 12 edges = 12a

When edge is increased by 2, sum of all edges = 12(a+2) = 12a + <em>24</em>

An increase of 24.

D. sum of these edges is increased by 24 inches -- True
