X/(-9) = 16

x/(-9) x (-9) = 16(-9)

x = 16(-9)

x = - 144

hope this helps

Please help me with the question.

Firdavs [7]

Answer:

$f(\boxed{-5})=\boxed{17}$

Step-by-step explanation:

The remainder theorem tells you that f(a) is the result of division of f(x) by (x-a).

Here, you have f(x)/(x+5) = 17, so a=-5 and f(-5) = 17.

Ragan makes beaded jewelry. The graph below shows the number of beads on varying cord lengths.

MakcuM [25]

Answer:

Option C) 34 inches

Step-by-step explanation:

We are given the following in the question:

The graph shows the number of beads on varying cord lengths.

The y-axis represents the number of beads and x-axis represents the cord length in inches.

The graph represents the equation:

$y = 2.52x + 1.61$

where y is the number of beads and x is the cord length.

We have to find the cord length of a necklace consisting of 88 beads.

Thus, we are given y = 88.

Putting this value in the equation, we get,

$y = 2.52x + 1.61\\88 = 2.52x + 1.61\\2.52x = 88 - 1.61\\2.52x = 86.39\\\\x = \displaystyle\frac{86.39}{2.52} = 34.28 \approx 34$

Thus, the cord length of necklace with 88 beads is approximatwly 34 inches.

Find the length of the segment with endpoints of (3, 2) and (-3, -6).

nevsk [136]

The distance between (3, 2) and (-3, -6) is 10 units

The correct answer is B) 10

Further explanation:

Given points are:

(x1,y1) = (3,2)

(x2,y2)=(-3,-6)

The distance formula is given by:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Putting the values

$d=\sqrt{(-3-3)^2+(-6-2)^2}\\=\sqrt{(-6)^2+(-8)^2} \\=\sqrt{36+64}\\ =\sqrt{100}\\d=10$

The distance between (3, 2) and (-3, -6) is 10 units

Vector u = <11, 12>, v = <-16, 6>, and w = <4, -5>. Match each vector operation with its resultant vector expr

MAVERICK [17]

3u - 2v + w gives the resultant vector as; <49, 19>

8u - 6v gives the resultant vector as; <184, 60>

7v - 4w gives the resultant vector as; <61, 104>

u - 5w gives the resultant vector as; <-9, 37>

<h3>How to find the resultant of vectors?</h3>

We are given the vectors;

u = 11i + 12j

v = -16i + 6j

w = 4i - 5j

1) 3u - 2v + w gives the resultant vector as;

3(11i + 12j) - 2(-16i + 6j) + 4i - 5j

⇒ 33i + 36j + 32i - 12j + 4i - 5j

⇒ 49i + 19j

⇒ <49, 19>

2) 8u - 6v gives the resultant vector as;

8(11i + 12j) - 6(-16i + 6j)

⇒ 88i + 96j + 96i - 36j

⇒ 184i + 60j

3) 7v - 4w gives the resultant vector as;

7(11i + 12j) - 4(4i - 5j)

⇒ 77i + 84j - 16i + 20j

⇒ 61i + 104j

4) u - 5w gives the resultant vector as;

11i + 12j - 5(4i - 5j)

11i + 12j - 20i + 25j

-9i + 37j

Find the value of x, y, and z in the rhombus below.

marin [14]

Consecutive angles in a paralleogram have sum 180

$\\ \rm\rightarrowtail 5z+4+86=180$

$\\ \rm\rightarrowtail 5z+90=180$

$\\ \rm\rightarrowtail 5z=90$

$\\ \rm\rightarrowtail z=18$

And

7y+3+86=180
7y+89=180
7y=91
y=13

And

opposite angles are equal

6x+8=86
6x=78
x=13
