Which of the following values does not satisfy the inequality-2x-6is less than or equal to 1 A)-4 B)-3 C)-2 D)-1

1 answer:

3 0

-2x - 6 < = 1
-2x < = 1 + 6
-2x < = 7...change the inequality sign when dividing by a negative number
x > = -7/2
x > = - 3.5

the one that does not satisfy the inequality is : -4...because it is less then -3.5

Answer:

$\dfrac{5}{3}$

Step-by-step explanation:

To find the gradient (slope) of the given linear relation, use arithmetic operations to isolate y:

Given relation:

$3y-5x=10$

Add 5x to both sides:

$\implies 3y-5x+5x=10+5x$

$\implies 3y=5x+10$

Divide both sides by 3:

$\implies \dfrac{3y}{3}=\dfrac{5}{3}x+\dfrac{10}{3}$

$\implies y=\dfrac{5}{3}x+\dfrac{10}{3}$

Slope-intercept form of a linear equation

$y = mx+b$

where:

m is the slope (gradient)
b is the y-intercept

Comparing the rewritten equation with the slope-intercept formula, the gradient (slope) of the given linear relation is ⁵/₃.

Doogle drove 30 and one-third miles toward his brother's house in one-third of an hour. About how long will the entire 100-mile

Olenka [21]

Answer:

$1\frac{9}{91}\ hours$

Step-by-step explanation:

we know that

30 and one-third miles is equal to

$30\frac{1}{3}\ mi=\frac{30*3+1}{3}=\frac{91}{3}\ mi$

one-third of an hour is equal to

$\frac{1}{3}\ h$

Applying proportion

$\frac{(1/3)}{(91/3)}\frac{h}{mi}=\frac{x}{100}\frac{h}{mi}\\ \\x=\frac{100}{91}\ h$

Convert to mixed number

$\frac{100}{91}\ h=\frac{91}{91}+\frac{9}{91}=1\frac{9}{91}\ h$

Answer:

The data A, B, C and D are Qualitative.

The data remains qualitative even when inputed as 1, 2, 3 and 4

Step-by-step explanation:

The data consisting of A, B, C and D is Qualitative , reason being that they can only be classified into categories.

Also, when the data is inputed as 1, 2, 3 and 4; the data remains Qualitative because theycannotbemeaningfully addd , subtracted, multiplied or divided.
