Which of the lines does not intersect the line y=-2x+3?

1 answer:

6 0

Lines that do not cross each other are parallel. Therefore they must have the same gradient. The gradient of the line is -2, so the answer is the only other line that has a gradient of -2.

Change 25/6 to mixed fraction

alex41 [277]

Answer:

$4\frac{1}{6}$

Step-by-step explanation:

To find this, first, we need to ask ourselves, "how many times does 6 go into 25?" The answer is 4 because 6 * 4 = 24 with 1 left over. Therefore, we know that the whole number is 4 and the fraction is 1/6, so the answer is $4\frac{1}{6}$ .

Choose the pair(s) of integers that can be substituted into the equation ax2 - 6x + c = 0 so that it has two real solutions.

Maksim231197 [3]

The options are not provided, but method is stated below

Answer:

Quadratic equation ax2 - 6x + c = 0

options would be given for a and c

substitute a and c
check for Discriminant
$b^2 - 4ac \geq 0$
36 -4ac $\geq 0$

These conditions will fetch us the result required among the options.

Note : the $\geq$ sign will give us the result for Two real unequal solutions and two real equal solutions. If we only need Real unequal solutions we only use > sign instead of $\geq$
