Answer:

U = -15

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

Step 2: Flip the equation.

Step 3: Multiply both sides by 5/(-6).

then you should get -15

Which relation is not a function

KiRa [710]

By definition a function can have only one value of y for any given value of x.

Since B. contains both (-1,2) and (-1,0), y has two values for the same value of x and thus B. cannot be a function...

Can anyone help me with this? im confused

kvasek [131]

Answer:

1,2,3 and 6 are similar triangles by AA similarity

Step-by-step explanation:

1) ∠DEC ≅ ∠FEG {Vertically opposite angles}

DC // GF

∠ECD ≅ ∠EGF {Alternate interior angles}

∠EDC ≅ ∠EFG {Alternate interior angles}

ΔDEC & ΔFEG are similar triangles by AA similarity

2)MN // QP

∠LQP ≅ ∠QMN {Corresponding angles }

∠LPQ ≅ ∠PNM {Corresponding angles}

ΔLQP & ΔLMN are similar triangles by AA similarity

3) In ΔSYE ,

∠S = 180 - 90 - 39

∠S = 51°

In ΔCHW,

∠H = 180 - 51 - 90

∠H = 39

ΔSYE and ΔCHW

∠S ≅ ∠W = 51°

∠Y ≅ ∠C = 90°

∠E ≅∠H = 39°

ΔSYE & ΔWCH are similar triangles by AA similarity

6) ∠P ≅ ∠Z {Given}

∠PXQ ≅∠ZXY {Vertically opposite angles}

ΔPXQ & ΔZXY are similar triangles by AA similarity

Factor by grouping. Then supply the term that is missing below. 4mn+3m+8n+6=(m+2)(?+3)

shusha [124]

Answer:

(m+2) (4n+3)

Step-by-step explanation:

4mn+3m+8n+6

4mn +8n +3m +6

Factor a 4n from the first term and a 3 from the second

4n (m+2) +3(m+2)

Factor out an (m+2)

(m+2) (4n+3)

Jose bought a pair of sneakers, a gaming headset and a T-shirt for $77. The headset cost two times

Margarita [4]

Answer:

The cheapest item is T shirt costing $13.

Step-by-step explanation:

Let the cost of T shirt = $ m

So, the cost of the headset = $ (2m)

and, The cost of Sneakers = $ ( m + 25)

Total amount spent by Jose = $77

Now, According to the question:

$ m + $ (2m) + $ ( m + 25) = $77

or, 4m + 25 = 77 ⇒ 4m = 77 - 25 = 52

or, m = 52/4 = 13

⇒ The cost of one T- Shirt = m = $ 13

The cost of the headset = (2m) = 13 x 2 = $ 26

The cost of Sneakers = $ ( m + 25) = 13+ 25 = $ 38

As, out of all costs, $13 is the lowest cost

Hence, the cheapest item is T shirt costing $13.

f the line passing through the points (1, a) and (5, −2) is parallel to the line passing through the points (2, 8) and (−5, a +

aleksandrvk [35]

Answer:

$a=-6$

Step-by-step explanation:

Line 1: (1, a) and (5, −2)

slope of the line is

$slope = \frac{y_2-y_1}{x_2-x_1} =\frac{-2-a}{5-1} =\frac{-2-a}{4}$

Line 2: (2, 8) and (−5, a + 7)

slope of the line is

$slope = \frac{y_2-y_1}{x_2-x_1} =\frac{a+7-8}{-5-2} =\frac{a-1}{-7}$

when the lines are parallel then slopes are equal

$\frac{a-1}{-7} =\frac{-2-a}{4}$

cross multiply it

$4(a-1)=-7(-2-a)$

$4a-4=14+7a$

subtract 4a from both sides

$-4=14+3a$

$-18=+3a$

divide both sides by 3

$a=-6$
