FALSE

Step-by-step explanation:

because in the number line the difference between -5and 5 is 10 because when we put those numbers in number line the distance from 0 to 5 is 5 and the distance from 0 to -5 is 5 addition of this two distances will give us 10 because we do not cosider about direction they found in distance

Zielflug [23.3K]

Answer:

x=-4

Step-by-step explanation:

(x+4) ^ (1/3) + (2x+8) ^ (1/3) = 0

Subtract (x+4) ^ (1/3) from each side

(x+4) ^ (1/3) - (x+4) ^ (1/3)+ (2x+8) ^ (1/3) = -(x+4) ^ (1/3)

(2x+8) ^ (1/3) = -(x+4) ^ (1/3)

Cube each side

(2x+8) ^ (1/3) ^3= -(x+4) ^ (1/3)^3

2x+8 = -(x+4)

Distribute the negative sign

2x+8 = -x -4

Add x to each side

2x+8 +x =-x+x-4

3x+8 = -4

Subtract 8 from each side

3x+8-8 =-4-8

3x =-12

Divide by 3

3x/3 = -12/3

x = -4

Can I have help with this one asap?

Answer:

In Δ CFD , CD is the LONGEST side.

Step-by-step explanation:

Here, the given Δ CSD is a RIGHT ANGLED TRIANGLE.

Now, as we know in a right triangle, HYPOTENUSE IS THE LONGEST SIDE.

So, in Δ CSD SD is the longest side as SD = Hypotenuse.

Now, an altitude CF is drawn to hypotenuse SD.

⇒ CF ⊥ SD

⇒ Δ CFD is a RIGHT ANGLED TRIANGLE with ∠ F = 90°

and CD as a hypotenuse.

⇒ In Δ CFD , CD is the LONGEST side.

Hence, CD is the longest side in the given triangle CFD.

DOES THE GRAPH OF THE STRAIGHT LINE WITH SLOPE OF 4 AND Y-INTERCEPT OF -3 PASS THROUGH THE POINT (-2, 9)

lisov135 [29]

Equation of the given line will be :

y = 4x - 3

now, let's plug the value of x as the x - coordinate of the above point (-2 , 9) to check whether it lies on the line or not.

$y = 4( - 2) - 3$

$y = - 8 - 3$

$y = - 11$

now, since value of isn't equal to the y - coordinate of the given point, so the point doesn't lies on the line.

Answer:

Part A) Option A. QR= 3 cm

Part B) Option B. SV=6.5 cm

Step-by-step explanation:

step 1

Find the length of segment QR

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem Triangle QRW and Triangle QSV are similar by AA Similarity Theorem

$\frac{QR}{QS}=\frac{QW}{QV}$

we have

$QS=9\ cm$ ---> because S is the midpoint QT (QS=TS)

$QW=2\ cm$ --->because V is the midpoint QU (QW+WV=VU)

$QV=6\ cm$ --->because V is the midpoint QU (QV=VU)

substitute the given values

$\frac{QR}{9}=\frac{2}{6}$

solve for QR

$QR=9(2)/6=3\ cm$

step 2

Find the length side SV

we know that

The Mid-segment Theorem states that the mid-segment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this mid-segment is half the length of the third side

In this problem

S is the mid-point side QT and V is the mid-point side QU

therefore

SV is parallel to TU

and

$SV=(1/2)TU$

$SV=(1/2)13=6.5\ cm$
