Answer 1

Answer:

No solution

Step-by-step explanation:

The given system of equations are ,

3x - y = -1 y = 3x - 5 = y-3x = -5

Adding both equations ,

=> 3x - y + y -3 x = -1-5

=> 0 = -6

Since we arrived at a contradiction the given pair of equations have No solution .

Given :

Area, A = 36cm²

Height, h = 8cm

Using the relation :

Area, A of triangle :

A = 1/2 * base * height

36 = 0.5 * base * 8

36 = 4 * base

base = 36 / 4

Base = 9 cm

Length of base is 9cm

factor the polynomial
4x^2 + 12 + 9

Answers

Answer:

The answer is [tex](2x+3)^2[/tex].

Step-by-step explanation:

Multiply the coefficient of the squared term and the constant. Then, find the factors that add up to 12:

[tex]4*9=36\\36:\{1*36,2*18,3*12,4*9,6*6\}\\6+6=12[/tex]

Split the middle term:

Part A: Xavier needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items. Choose the correctly written inequality to represent the number of cans, c, that Xavier must still collect (before solving)
A 64 + c ≥ 120
B 64 + c < 120
C c - 120 ≤ 64

Answers

Answer:

Step-by-step explanation:

He needs to collect at least 120 so if c is what he must still collect

64 +c must be greater than or equal to 120

A child has a box of colored building blocks. He will choose one block without looking. The odds against choosing a blue block are 13/4. What is the probability of choosing a blue block?

Answers

Answer:

The answer is "0.2352".

Step-by-step explanation:

Given:

The chance of selecting a odds blue block [tex]= \frac{13}{4}[/tex]

[tex]=\frac{\text{Amount of unfavourable blue block evets} \ (13)}{\text{Amount of unfavourable blue block evets} \ (4)}[/tex]

total number of events are 13+4= 17

Calculating the probability of choosing the blue block

[tex]=\frac{\text{Amount of unfavourable blue block evets} }{\text{Amount of unfavourable blue block evets} } \\\\ = \frac{4}{17} \\\\ =0.2352[/tex]

Write the equation of the circle.

A: (x+3)2+(y−6)2= 2

B: (x−3)2+(y+6)2= 2

C: (x+3)2+(y−6)2= 4

D: (x−3)2+(y+6)2= 4

Answers

Answer:

C. (x + 3)² + (y - 6)² = 4

Step-by-step explanation:

Get the center and radius from the graph.

Center is: (-3, 6)Radius is: 2

Use the circle formula:

(x - h)² + (y - k)² = r²

We have:

h = -3, k = 6, r = 2

Substitute and get the equation:

(x - (-3))² + (y - 6)² = 2² ⇒(x + 3)² + (y - 6)² = 4

Correct choice is C
