pentagon [3]3 years ago
3 0

Answer:

2<x<3

Step-by-step explanation:

4x-4<8 AND 9x+5>23

Solve the first inequality

4x-4<8

Add 4 to each side

4x-4+4 <8+4

4x<12

Divide by 4

4x/4 <12/4

x <3

Solve the second inequality

9x+5>23

Subtract 5 from each side

9x+5-5>23-5

9x >18

Divide by 9

9x/9>18/9

x>2

Put together

x<3 and x>2

2<x<3

10-2(2x+1)=4(x-2)solve each equation for x graph your Solution on a number line ​
stepladder [879]

Answer:

No solution

Step-by-step explanation:

Actually, you have only one equation here.  We will solve it for x.

Performing the indicated multiplication, we obtain:

10-2(2x+1)=4(x-2)  =>  10 - 4x - 2 = 4x - 8, or 10 - 2 = -8.  This can never be true, so this equation has no solution.

Which of the following is the contrapositive of the conditional below?
masha68 [24]

Answer:

If 3 + 4 ≠ 6, then 2 · 5 = 10.

Step-by-step explanation:

To form the contrapositive of the conditional statement, interchange the hypothesis and the conclusion of the inverse statement. The contrapositive of "If it rains, then they cancel school" is "If they do not cancel school, then it does not rain." If p , then q .

true or false:the points (6,13),(21,33),(99,137)all lie on the-same line. the equation of the line is y=4/3x +5
Anit [1.1K]

The answer is true.

Step-by-step explanation:

To find the points all lie on the same line, we need to substitute the points in the equation of the line, to determine if the values on both sides of the equation are equal.

Substituting the point (6,13) in the equation of the line, we get,

\begin{aligned}y &=\frac{4}{3} x+5 \\13 &=\frac{4}{3}(6)+5 \\&=4(2)+5 \\&=8+5 \\13 &=13\end{aligned}

Thus, the values on both sides are equal. The point (6,13) lie on the same line.

Substituting the point (21,33) in the equation of the line, we get,

\begin{aligned}y &=\frac{4}{3} x+5 \\33 &=\frac{4}{3}(21)+5 \\&=4(7)+5 \\&=28+5 \\33 &=33\end{aligned}

Thus, the values on both sides are equal. The point (21,33) lie on the same line.

Substituting the point (99,137) in the equation of the line, we get,

\begin{aligned}y &=\frac{4}{3} x+5 \\137 &=\frac{4}{3}(99)+5 \\&=4(33)+5 \\&=132+5 \\137 &=137\end{aligned}

Thus, the values on both sides are equal. The point (99,137) lie on the same line.

Thus, all the three points lie on the same plane.

Hence, the answer is true.
