Subtraction. Subtract 5 from both sides to get -3x<23-5
-3x<18. Hope this helps.

Moving 5 on the right side of the inequality.

-3x+5\ \textless \ 23\\&#10;-3x\ \textless \ 23-5\\&#10;-3x\ \textless \ 18\\&#10;x\ \textgreater \ -6

Answer:

FC = 27, QC = 18

Step-by-step explanation:

The centroid Q is \frac{1}{3} the way along CF , therefore, QF is half as long as CQ

Given FQ = 9, then

QC = 2 × 9 = 18

FC = FQ + QC = 9 + 18 = 27

If anyone knows how to do this pls help I could really use it
nekit [7.7K]
The perimeter of the triangle, namely the sum of all its 3 sides, is 110.

now, the three sides are in a 6:7:9 ratio, namely, if we divide 110 by (6+7+9), it will give us hmmm 110/22, a quotient of 22 equal pieces, namely how many times 22 would go into 110.

now, the small side, takes 6 of those pieces, the medium side takes 7 of them and the largest takes 9 of those pieces.

110/22 = 5

the small side is then 6(5).

the medium side is 7(5).

and the largest side is 9(5).

add them up, and you'd get the perimeter, 110 inches.

What is the vertex of y=3|x+1|-2
spin [16.1K]

Answer:

(-1,-2)

Step-by-step explanation:

Generally, the absolute value function can be expressed like so:

f(x) = y = a|x-h|+k, where vertex: (h,k)

Rewriting our function here ever so slightly gives us: y = 3|x-(-1)|+(-2)

So the vertex is at (-1,-2)

All help is appreciated. Find m
Annette [7]

Answer:

B.) 73°

Step-by-step explanation:

To find m<A, first you must find it's supplementary angle. In order to do this, you must determine the missing interior angle. We'll call the missing angle x

A pentagon has 540°. Add up the known angles.

96°+118°+115°+104°+x = 540°

433°+x = 540°

x = 107°

Now that we know the value of x, we can find the m<A. Supplementary angles are two angles that add up to 180°, which is a flat line. We can see in the diagram that m<a + 107° is a flat line, meaning m<a + 107° = 180°

Solve accordingly.

m<a + 107° = 180°

m<a = 73°
