Step-by-step explanation:

1. r(-3) is just plugging in -3 into the r(x) function where ever we see x.

1a. r(-3)=-2(-3)^2+1=-17

2. We are left with q(-17).

2a. We plug -17 into where we x in q(x).

3. q(-17)=-(-17)+2=19

GuDViN [60]

Answer:

See explanation

Step-by-step explanation:

The triangles below are congruent and their corresponding parts are marked.

a) Angles marked with one arc are congruent, so $\angle B\cong \angle Z.$

Angles marked with two arcs are congruent, so $\angle A\cong \angle Y.$

Angles marked with three arcs are congruent, so $\angle C\cong \angle X.$

b) Sides marked with one segment are congruent, so $\overline {AC}\cong \overline {YX}.$

Sides marked with two segments are congruent, so $\overline {BC}\cong \overline {ZX}.$

Sides marked with three segments are congruent, so $\overline {AB}\cong \overline {YZ}.$

c) Name teo congruent triangle following the congruence of angles:

$\triangle BCA\cong \triangle ZXY$

Which equations represent the line that is parallel to 3x − 4y = 7 and passes through the point (−4, −2)? Select two options. y

xz_007 [3.2K]

Answer:

The equation of the parallel line to the given equation is

3 x-4 y = -4 and

The equation of the parallel line to the given equation is

$y = 1 + \frac{3 x}{4}$

Step-by-step explanation:

Explanation:-

Given equation of the line 3 x -4 y = 7 and given point ( -4 , -2 )

The equation of the parallel line to the given equation is

3 x - 4 y = k

it is passes through the point ( -4 , -2)

3 (-4) - 4 ( -2) = k

-12 +8 = k

k = -4

The equation of the parallel line to the given equation is

3 x- 4 y = -4

Dividing '4' on both sides , we get

$\frac{3 x-4 y}{-4} = 1$

$\frac{-3 x}{4} +y =1$

$y = 1 + \frac{3 x}{4}$

Conclusion:-

∴ The equation of the parallel line to the given equation is

3 x- 4 y = -4

and

The equation of the parallel line to the given equation is

$y = 1 + \frac{3 x}{4}$

You are selling lemonade for $1.50, a bag of kettle corn for $3, and a hot dog for $2.50 at a fair. Write and simplify an expres

kozerog [31]

Answer:

1.5p + 3p + 2.5p

Step-by-step explanation:

This expression, 1.5p + 3p + 2.5p, will represent the amount of money received when p people buy one of each food item.

Since the price of each is the coefficient for p, this will represent how much money will be gained from each food item. All 3 terms will be added together to represent the total amount of money gained from selling all 3 items.
