Answer:

Step-by-step explanation:

Plug in the values of x in the equation and find the value of y

6) y = - 3x + 5

Plugin x = -1 , y = -3*(-1) + 5 = 3 + 5 = 8 (-1 , 8)

Plugin x = 1 ; y = -3*1 + 5 = - 3 + 5 = 2 (1, 2)

Plugin x = 3 ; y = -3*3 + 5 = -9 + 5 = -4 (3, -4)

Plugin x = 4 ; y = -3*4 + 5 = -12+5 = -7 (4 , - 7)

7) y = -4x

Plugin x = -2 ; y = -4*(-2) = 8 (-2 , 8)

Plugin x = -1 ; y = -4 *(-1) = 4 (-1 , 4)

Plugin x = 0 ; y = 0 (0 , 0 )

Plugin x = 2; y = -4*2 = -8 (2 , -8)

What is the minimum number of degrees that an equilateral triangle can be rotated before it carries onto itself?

mash [69]

Since the triangle has equal sides it will carry onto it self at 120, since it can rotate 360 grades only and it has 3 sides so it will rotate in one third of 360 so 120

i hope i helped you

Which equation involves a prime quadratic and cannot be solved by factoring? A. x2 + 5x − 4 = 0 B. x2 − x − 6 = 0 C. x2 + 3x − 4

Damm [24]

Answer:

Option A

Step-by-step explanation:

We can try to factorize all the options one by one.

For A:

$x^{2} +5x-4\\=> x^{2}+4x+x-4\\=>x(x+4)+1(x-4)$

We can see that the quadratic expression cannot be solved by factorization as the factors at the end of factorization are not equal in both brackets. So Option A is the correct answer for the given question.

Moreover we can also note that all the other quadratic expressions can be factorized ..

Area of a triangle is given by the formula A=1/2 bh. The area of the triangle shown to the right is 56 sq. units. Find its base

Westkost [7]

Given

base=2x+6
height=x+4

and
area=56 square units

56=1/2 times (2x+6) times (x+4)
times bot sides by 2
112=(2x+6)(x+4)
expand
112=2x²+14x+24
divide both sides by 2
56=x²+7x+12
minus 56 both sides
0=x²+7x-44
factor
waht 2 numbers mulitply to get -44 and add to get 7
11 and -4
0=(x-4)(x+11)
set to 0

x-4=0
x=4

x+11=0
x=-11
false, measures can't be negative

x=4

height=x+4
height=4+4=8

base=2x+6
base=2(4)+6=8+6=14

x=4 and base=14 and height=8

The total cost of 5 boxes of pasta is $13. There are 12 ounces of pasta in each box. Each box of pasta cost the same amount. Wha

Bas_tet [7]

Answer: $10.40

Explanation:

First, find the cost of 1 box of pasta. 13/5 = 2.6, so $2.60 a box.

Next, find how many boxes there are. 48/12 = 4, so 4 boxes of pasta.

Finally, multiply 4*2.6 to get the final cost.
