Answer:

(1,2)

Step-by-step explanation:

first, make the equations equal each other so you can solve for x

8x-6=2x

this gives you 1

then, use what you got for x and plug it in for one of the original questions. I am gonna use 2x since its the easiest to plug in and solve

2(1)=2, so y is 2

so then x=1 and y=2

then put that into (x,y) which is (1,2)

Answer: (1,2)
This is because you first solve for x and substitute the value for x into the equations given. x =1 and y= 2

Triangle MNP has side lengths 3.5 cm, 4.1 cm, and 4.3 cm. A triangle with what side lengths would be similar to triangle MNP?
atroni [7]

Answer:

Option 1,

The triangle MNP is similar to the triangle with side lengths 35 cm, 41 cm, 43 cm

Step-by-step explanation:

Given triangle MNP has side lengths 3.5 cm, 4.1 cm, and 4.3 cm. we have to find the similarity triangle sides from the given option.

As we know, the two triangles are similar if the measures of the corresponding sides of two triangles are proportional.

For the first option: 35 cm, 41 cm, 43 cm

\frac{3.5}{4.1}=\frac{4.1}{41}=\frac{4.3}{43}=\frac{1}{10}

which shows that the sides are proportional.

we have to choose only one option ∴ we needn't have to check the others

Hence, the triangle MNP is similar to the triangle with side lengths 35 cm, 41 cm, 43 cm

Find the equation of line b described below, in slope-intercept form
Serjik [45]

Given:

Line a is perpendicular to line b .

Line a passes through the points (1,-8) and (9,-12) .

Line b passes through the point (-8, -16).

To find:

The equation of b.

Solution:

Line a passes through the points (1,-8) and (9,-12) . So, slope of line a is

m=\dfrac{y_2-y_1}{x_2-x_1}

m_a=\dfrac{-12-(-8)}{9-1}

m_a=\dfrac{-12+8}{8}

m_a=\dfrac{-4}{8}

m_a=-\dfrac{1}{2}

Product of slopes of two perpendicular lines is -1.

m_a\times a_b=-1

-\dfrac{1}{2}\times a_b=-1

b=2

Slope of line b is 2.

If a line passing through a point (x_1,y_1) with slope m, then equation of line is

y-y_1=m(x-x_1)

Line b passing through (-8,-16) with slope 2. So, equation of line b is

y-(-16)=2(x-(-8))

y+16=2(x+8)

y+16=2x+16

Subtract 16  from both sides.

y=2x

Therefore, the equation of line b is y=2x.

Rewrite the parametric equations by eliminating the parameter. Select ONE.
Vinil7 [7]

Answer:

Y=(X-7)/2

Step-by-step explanation:

we have

X=2t+3 -----> equation A

Y=t-2 -----> t=Y+2 -----> equation B

Substitute equation B in equation A

X=2(Y+2)+3

X=2Y+4+3

X=2Y+7

solve for Y

2Y=X-7

Y=(X-7)/2
