Answer:

Explanation:

Assume that the number we are looking for is x

one tenth is interpreted into $\frac{1}{10}$

Now, we know that one tenth of the number is 7, this means that:

$\frac{1}{10}$ * x = 7

Solve for x by multiplying both sides of the equation by 10, we get:

$\frac{1}{10}$ * x * 10 = 7 * 10

x = 70

Hope this helps :)

$7:0.1=7:\frac{1}{10}=7\times\frac{10}{1}=7\times10=\fbox{70}$

$check:\\0.1\times70=7$

How many points of intersection does this system have? y = 3 x minus 4. Negative 3 x y = 4. Zero points of intersection one poin

defon

A point of intersection is a point where two lines or curves meet.

There are zero points of intersection.

Given

The equations are;

$\rm y = 3x-4\\\\-3x+y=4$

<h3>What is the point of intersection?</h3>

A point of intersection is a point where two lines or curves meet.

There are two methods to find a point of intersection graphically by graphing the curves on the same graph and identifying their points and another one is to solve the equation and find the value of x and y.

Adding both the equation

$\rm y-3x-3x+y=-4+4\\\\2y=6x\\\\y=3x$

Substitute the value of y in the equation

$\rm y=3x-4\\\\3x=3x-4\\\\3x-3x=-4\\\\0=-4$

Hence, there are zero points of intersection.

Which choice is a graph of the solution set for 12 - X < 8? Pleaseeeee helpppppp NUMBER 14

yarga [219]

Answer:

Hope this helps!

explanation:

we solve the inequality and to do that we must first subtract 12 from both sides, which gets us -x<-4, then we divide both sides by -1, which gives us x>4, since we have to flip the sign when we divide by a negative. when we graph this, there will be a circle around 4 and the arrow pointing to the right, since it's greater than.

Use always, sometimes or never to make a true statement:

viva [34]

Answer:

1. Intersecting lines are always coplanar

2. Two planes never intersect in exactly one point

3. Three points are always coplanar

4. A plane containing two points of a line always contains the entire line

5. Four points are sometimes coplanar

6. Two lines never meet in more than one point.

7. Two skew lines are never coplanar

8. Line TQ and Line QT are always the same line.

Step-by-step explanation:

Note: Coplanar means "In the same plane"

1. Each line exist in many planes. But different lines must share at least one plane for them to intersect. That is why intersecting lines are always coplanar.

2. Two planes never intersect at exactly one point because only lines intersect at a point. Planes can only intersect along a line.

3.Three points are always coplanar because in geometry, a group of points are coplanar because there is a geometric plane that they all lie on.

4. A plane containing two points of a line always contains the entire line. Yes

5. Four points are only sometimes coplanar because there is a probability that they may all not lie on the same plane

6. Two lines never meet in more than one point because lines are basically straight and cannot bend over to intersect at another point

7. Two skew lines are never coplanar because skews lines are lines that do not intersect and are never parallel.

8. Line TQ and Line QT are always the same line because a line is straight and extends from one point to the other. So, if a line is labelled TQ calling it QT means the same thing
