Solve the system of equation using subtraction 3x+2y=7 y=-3y+11

1 answer:

8 0

Assumig 2nd euqation is y =-3x+11
using subtraction

minus y both sides and minus 11
-3x-y=-11

add to other equation to eliminate y's

-3x-1y=-11
3x+2y=7 +
0x+1y=-4

y=-4

sub back

y=-3x+11
-4=-3x+11
minus 11 both sides
-15=3x
divide both sides by 3
-5=x

(x,y)
(-5,-4)

A line, y mx + b, passes through the point (2, 3) and is parallel to y 2x + 5. What is the value of b?

Vitek1552 [10]

Answer:

Step-by-step explanation:

If a line is parallel to another it must have the same slope

The slope/intercept form of a line is y = mx + b where m is the slope and b the y intercept

The line y = 2x + 5 has slope 2

So the slope of the line that passes through (2,3) must also have the slope 2

We have
y = 2x + b; Substituting x =2, y =3 in this equation gives us
3 = 2 (2) + b or b = -1

Hence the equation of the line is
y = 2x -1

Cross-check

Substitute for x = 2 ==> y = 2(2) - 1 = 3 which is consistent

Copying a given segment is the process in which a given line segment is drawn following the required steps so that both object and image have the same length. Therefore,

i. PQ = 12 cm

ii. MN = 12 cm

Thus, PQ = MN

Construction is a process that requires the use of materials and instruments to produce a required image. This involves following stated or required steps.

A given line segment can be copied by following appropriate steps. Such that both lines would have the same length, and would be parallel to each other or as required.

The given question requires following the stated steps to produce the required construction. Such that line segment NM is the image of PQ, and both have equal length.

The required construction for the question is attached to this answer.
