The number that each term of the equation be multiplied by to eliminate the decimals before solving -m+0.02+2.1m=-1.45-4.81m
It would be better to group all similar numbers.
<span>-m+0.02+2.1m=-1.45-4.81m
</span>-m + 2.1m + 4.81m = -1.45 - 0.02
5.91m = -1.47
The equation shown above, in order for us to eliminate the decimal,
we need to divide 5.91.
Okay, so all this question wants you to do is plug in 2 for x and solve for your output, aka y.
y = -4x² - 8
when x = 2....
y = -4(2)² - 8
y = -16 - 8
y = -24
so, when your input is 2, your output is -24.
Answer:
50.28 sq. cm.
Step-by-step explanation:
A and B are centers of two circles of radii 8 cm and 1 cm such that AB =13 cm.
Now, angle ACB =90 degree where C is the center of another circle which touches the above two circles.
Now, ABC forms a right triangle where AB = 13 cm, AC = (r + 8) cm and BC = (1 + r) cm.
{Where r is the radius of the circle C.
Applying Pythagoras Theorem. AB² = AC² + BC²
⇒ 13² = (r + 8)² + (r + 1)²
⇒ 169 = r² + 16r + 64 + f² + 2r + 1
⇒ 2r² + 18r - 104 = 0
⇒ r² + 9r - 52 = 0
⇒ (r + 13)(r - 4) = 0
Hence, r = 4 {As the value of r can not be negative}
Therefore, the area of the circle C is π(4)² = 50.28 sq. cm. (Answer)
Answer:
21 cuz it ✅ and if don't think it i don't known what it is
Answer:
Step-by-step explanation:
Given
(a): Write as additive inverse.
An additive inverse is of the form a + (-b)
In this case:
So, the expression can be represented as:
(b): Number line representation
When the expression in (a) is solved.
The result is:
This means that the number line must accommodate 7 and -1.
Having said that, options (b) and (c) are out because their range is 0 to 15 and this excludes -1.
Option (d) is a wrong representation of
Hence, (a) is correct
