1)
15 > -2x-9
15+9 > -2x
24÷(-2) < x (the sign flips because you divide both sides by a negative number)
Hence, x > -12

2)
3x + 8 < 29
3x < 29-8
3x < 21
x < 7 (tada the answer)

Answer:

Problem #1: x > -12

Problem #2: x < 7

Step-by-step explanation:

Hello!

Problem #1: We must isolate x (solve the inequality for x). First, add 9 to both sides: 24 > -2x. The next step has two parts: Divide both sides by -2 and then reverse the direction of the inequality sign:

24 -2x

---- < ------- => -12 < x. or x > -12

-2 -2

Problem #2: Subtract 8 from both sides: 3x < 21. Then, isolate x by dividing both sides of this rersult by 3: x < 7.

Ten less than the square of A. 10-a^2 or a^2- 10

s344n2d4d5 [400]

Hi!

Ten less than the square of A.

So LESS is implying subtraction, therefore the 10 needs to be subtracted FROM something, If we look at our options, B is implying that 10 is being subtracted from something, which is what we want!

Therefore our answer is a^2-10

Hope this helps!

Question 15 of 43

Andrews [41]

Answer:

Option A

Step-by-step explanation:

$\frac{12}{25} \times \frac{11}{24} \times \frac{10}{23} \times \frac{9}{22}$

we start with 12 red marbles out of 25 marbles, that's the probability for the first.

in the second step we have one red marble less, wich also means one marble less overall

and so on

$\frac{12 \times 11 \times 10 \times 9}{25 \times 24 \times 23 \times 22}$

$= \frac{11880}{303600}$

can be reduced by 1320 (step by step) to

$\frac{9}{230}$

Answer:

(-3, 3)

explanation:

original coordinate of C: (3, 5)

if reflected over y axis, use the formula: (x,y) → (-x, y)

new coordinate: (-3, 5)

If translated vertically, there will be change in y axis

then vertically -2 units:

(-3, 5-2) → (-3, 3)

What is the value of a?

Anna007 [38]

Answer:

15 units

Step-by-step explanation:

By using the Pythagoras Theorem,

C^2 = A^2 + B^2

Substitute in the given values,

25^2 = a^2 + 20^2

625 = a^2 + 400

625 - 400 = a^2 + 400 - 400

a^2 = 225

$a = \sqrt{225}$

= 15

Hope this too helped! ^^

I'd recommend watching a video or two on the topic of Pythagoras Theorem, if this explanation isn't clear enough.
