-4(x+1)+5=17 solve for x

First distribute -4 to all terms within the parenthesis

-4(x) = -4x

-4(1) = -4

-4x - 4 + 5 = 17

Simplify. Combine like terms

-4x (-4 + 5) = 17

-4x + 1 = 17

Isolate the x. Do the opposite of PEMDAS. Note the equal sign. What you do to one side you do to the other.

Subtract 1 from both sides

-4x + 1 (-1) = 17 (-1)

-4x = 16

Divide -4 from both sides

-4x/-4 = 16/-4

x = 16/-4

x = -4

-4 is your answer

hope this helps

-4(x + 1) + 5 = 17

Distribute -4 inside the parentheses.

(-4x - 4) + 5 = 17

Combine like terms (-4 + 5).

-4x + 1 = 17

Subtract 1 from both sides.

-4x = 16

Divide both sides by -4.

x = -4

Find the distance between points (5,1) and (3,4) to the nearest tenth
Charra [1.4K]

Answer:

3.6 units (nearest tenth)

Step-by-step explanation:

distance formula

= \sqrt{(x1 - x2)^{2}  + (y1 - y2)^{2} }

Thus, distance between the 2 points

= √[(5 - 3)² + (1 - 4)²]

= √[ 2²+ ( - 3)²]

= √13

= 3.6 units (nearest tenth)

PLEASE HELP : A rectangle has a length that is 15 more than its width. A second rectangle with a perimeter of 72 has a width tha
SashulF [63]

Answer:

length = 24, width = 9

Step-by-step explanation:

Let's call the length and width of the first rectangle w + 15 and w respectively. This means that the length and width of the second rectangle is (w + 15) - 2 and w + 5 respectively. Since the perimeter of the second rectangle is 72, we can write:

2 * ((w + 15) - 2 + w + 5) = 72 because perimeter = 2 * (length + width)

(w + 15) - 2 + w + 5 = 36 (Divide by 2)

2w + 18 = 36 (Combine like terms)

2w = 18 (Subtract 18)

w = 9 (Divide by 2)

This means that the length and width are 24 and 9.

Consider A = (-9,4) and B (11,17). = Point P₂ partitions the segment from B to A in a 3:5 ratio. Find the coordinates of point P
Bogdan [553]

An easy way to do this is to parameterize the directed line segment from B to A by the function

\ell_{B\to A}(t) = (1-t) B + t A = (1 - t) (11, 17) + t (-9, 4)

with 0 ≤ t ≤ 1.

The point P₂ splits up AB so that BP₂ = 3/8 AB and AP₂ = 5/8 AB. Then we reach the point P₂ when t = 3/8, so its coordinates are

P_2 = \ell_{B\to A}}\left(\dfrac38\right) = \dfrac58 (11,17) + \dfrac38 (-9,4) = \boxed{\left(\dfrac72, \dfrac{97}8\right)}
