4 0

Answer:

${ \tt{7 {x}^{2} + 3x = 0 }} \\ { \tt{x(7x + 3) = 0}}$

Either x = 0 or ( 7x + 3 ) = 0 :

${ \tt{7x + 3 = 0}} \\ { \tt{x = - \frac{3}{7} }}$

Answer:

${ \bf{(0, \: - \frac{3}{7}) }}$

Identify the 4 basic transformation

Pavlova-9 [17]

Answer:

Rotation, Reflection, dilation, and translation

Step-by-step explanation:

Rotation: Just rotating the shape; spinning the shape around a point

Reflection: Your shape is either reflecting on the x axis or y axis meaning it is either side by side (y) or up and down (x)

Dilation: Your shape is either going to shrink or get bigger

Translation: Shifting all the points of the figure

Write the resultant of the two vectors as an ordered pair. –6 5 and 6 –5

RideAnS [48]

Answer:

Resultant vector of two vectors is (0, 0).

Step-by-step explanation:

in this question two vectors having ordered pair (-6, 5) and (6, -5) have been given.

We can represent these vectors in the form of

$\vec{A}=-6\hat{x}+5\hat{y}$

and $\vec{A'}=6\hat{x}+(-5)\hat{y}$

Now the resultant of these vectors will be = A + A'

A + A' = $\vec{A}=-6\hat{x}+5\hat{y}$ + $\vec{A'}=6\hat{x}+(-5)\hat{y}$

So the resultant vector = (0 + 0)

Therefore the resultant will be (0, 0)

Find the location of the x-intercept, the location of the y-intercept, and the slope for the line

I am Lyosha [343]

Answer:

x intercept (15/4,0)

y intercept (0,2)

slope 8/15

Step-by-step explanation:

15y − 8x = 30.

To find the x intercept, set y =0

15(0) -8x = 30

8x = 30

Divide each side by 8 to solve for x

8x/8 = 30/8

x = 15/4

To find the y intercept, set x =0

15y -8(0) = 30

15y = 30

Divide each side by 15

15y/15 = 30/15

y =2

To find the slope we solve the equation for y

15y − 8x = 30.

Add 8x to each side

15y − 8x+8x =8x +30.

15y = 8x +30

Divide each side by 15

15y/15 = 8x/15 +30/15

y = 8/15x +2

The slope is 8/15

What is the remainder when x^2-5x-22 is divided by x+3?

Zielflug [23.3K]

First, you need to find the zero of x+3, which is -3
then you multiply -3×1, which equals -3
the reason why I multiplied -3×1 is because the 1 is the coefficient of x^2 but we just don't see it because we don't need to.
once we get -3 we add that to the next coefficient (-5)
-3+-5=-8
we take the sum (-8) and multiply that to -3 (the zero of x+3)
we get 24, so we add -22+24=2
-22 Is the next coefficient to come and 2 is our remainder
the new equation is: x-8 remainder 2

Bryce bought a bag of cashews.he served 7/8 pound of cashews at a party. This amount represents 2/3 of the entire bag. The equat

LUCKY_DIMON [66]

Ok so for this problem you you divide 2/3 n by 2/3 and 7/8 by 2/3
you get $n= \frac{7}{8} / \frac{2}{3}$
to divide fraction you flip the divider over to find the reciprocal
2/3 > 3/2 also you change the division symbol to the multiplication symbol
the equation now is $n= \frac{7}{8} * \frac{3}{2}$
now you multiply to get 21/16
the answer is 1 5/16 after you simplify it
