What is the answer to this

Mathematics
1 answer:
lukranit [14]3 years ago
8 0

Answer:

B.

Step-by-step explanation:

5x + y = 3

10x + 2y = - 3

y = - 5x + 3

2y = - 10x - 3

y = - 5x + 3

y = - 5x - 3/2

These lines have the same slope, but different y-intercept, so they are parallel.

Find the length of side AB.
melamori03 [73]

Answer:

8.86 cm

Step-by-step explanation:

The sine rule shows the relationship between the sides of a triangle and its opposite sides. Sine rule states that given a triangle with side a and opposite angle A, side b and opposite angle B, side c and opposite angle C then:

\frac{a}{sin(A)} =\frac{b}{sin(B)}=\frac{c}{sin(C)}

From the image attached, let AB = x, its opposite angle is 41°. BC = 13.5 cm and its opposite angle is 90°  (right angle). Therefore using sine rule:

\frac{x}{sin(41)} =\frac{13.5}{sin(90)} \\\\x=sin(41)*\frac{13.5}{sin(90)}\\\\x=8.8568\\\\ x=8.86\ cm\ to\ 3\ s.f

x = AB = 8.86 cm

Suppose that f(x)=x2 and g(x) =4/5x2. Which statement best compares the graph of f(x)?
Roman55 [17]

Answer:

See below.

Step-by-step explanation:

Are f(x)=x2 and g(x) =4/5x2 correctly written?

This answer assumes they are supposed to be:

f(x)=x^2 and g(x) = (4/5)x^2

If these revisions are correct, g(x) would produce values that are (4/5) of f(x).

See attached graph.

I don't see any of the options for "best statement."

Find the slope of the line containing the points (2,6)and(-4,3)
faltersainse [42]
M= 1/2
to find this you plug in the points into the the formula m=y2-y1 / x2-x1

m=3-6 / -4-2
m=-3 / -6
this simplifies to m=1/2
