$x=-2 \\ y=-3$

The equation $3x\leq2y$ can now be rewritten: $3\times(-2)\leq2\times(-3)$

And simplified.

$-6\leq-6$

Which means the statement is true because operation states less than or equal to.

Direct answer: True

Follow the directions to solve the system of equations by elimination.

Ber [7]

8x + 7y = 39
4x - 14y = -68

(multiply each term in second equation by -2)

8x + 7y = 39
-8x + 28y = 136

(add both equations)

35y = 175

(divide both sides by 35)

y = 5

(substitute value of y in one of the equations)

8x + 7(5) = 39
8x + 35 = 39
8x = 4
x = 1/2
(x, y) = (1/2, 5)

A survey of a group’s viewing habits over the last year revealed the following information: (i) 28% watched gymnastics (ii) 29%

almond37 [142]

Answer: D) 52%

Step-by-step explanation:

G = gymnastics

B = baseball

S = soccer

G = 28%

BA = 29%

S = 19%

G and BA = 14%

BA and S = 12%

G and S = 10%

GBS = 8%

So, as we can see at the Venn diagram attached (consider every number in %)

GBS = 8

A = G and S - GBS = 10 - 8 = 2

B = G and BA - GBS = 14 - 8 = 6

C = BA and S - GBS = 12 - 8 = 4

Only G = G - A - B - GBS = 28 - 2 - 6 - 8 = 12

Only BA = BA - B - C - GBS = 29 - 6 - 4 - 8 = 11

Only S = S - A - C - GBS = 19 - 2 - 4 - 8 = 5

So, 2+6+4+12+11+5+8 = 48

100 - 48 = 52%

Find the gradient of the line segment between the points (4,3) and (5,6).

<h2>SOLVING</h2>

$\Large\maltese\underline{\textsf{A. \space What is Asked}}$

Find the gradient of the line segment between the points $\bf{(4,3)\:and\:(5,6)}$

$\Large\maltese\underline{\textsf{B. This problem has been solved!}}$

The formula used, here is

$\bf{m=\dfrac{y2-y1}{x2-x1}$

$\cline{1-2}$

Now let's put in the co-ordinates from these two points.

$\bf{m=\dfrac{6-3}{5-4}}$ | subtract on top & bottom

$\bf{m=\dfrac{3}{1}}$ | divide

$\bf{m=3}$

$\cline{1-2}$

$\bf{Result:}$

$\bf{=m=3}$

$\boxed{\bf{ aesthetic\not101}}$
