Answer:
Step-by-step explanation:
35=-5t²+10t+22
5t²-10t+13=0
disc =b²-4ac=(-10)²-4×5×13=100-260=-160<0
t is imaginary.
So ball never reaches a height of 35 m

help please i want help please
for the equation x + y = 3. How many possible values for x are there if x and y are both whole numbers?
A.2
B.3
C.4
Answer:
A
Step-by-step explanation:
Because it is 2+1 and 3+0, those are the only solution, therefore A is correct
======================================================
Explanation:
The set of whole numbers is {0, 1, 2, 3, ...}
So we include 0 and any positive number that doesn't have decimal or fractional components to it. Negative values are not included.
If we plug in x = 0, then x+y = 3 solves to y = 3If we plug in x = 1, then x+y = 3 solves to y = 2If we try x = 2, then x+y = 3 solves to y = 1Lastly, x = 3 leads to y = 0Whatever you pick for x, the y value must add to it to get 3. Both x and y must be numbers from the set of whole numbers.
There are four cases shown in the bullet points above, so we have four different solutions. We can't move onto x = 4 because the y solution would be y = -1, but -1 is not in the set of whole numbers.

A. lnk/ln5
B. ln(k/5)
C.1/5*ln k
D. 5 * 1/ln k

I am having a lot of struggles please help
Answer: x = 23
∠DBC = 23°
∠ABC = 157°
Step-by-step explanation: A straight line is 180°, which means that ∠DBC and ∠ABC must equal 180°.
180 - 19 = 161
23 × 6 = 138
138 + 23 = 161
If x = 23°, then ∠DBC is 23°.
For ∠ABC, (6(x) + 19°
6(23) + 19°
6 × 23 = 138
138 + 19 = 157
∠ABC = 157°

Write the coordinate of A’ after A (5,3) got reflected over the x-axis.
Answer:
A'(5, -3)
Step-by-step explanation:
Reflection over the x-axis changes the sign of the y-coordinate:
(x, y) ⇒ (x, -y)
A(5, 3) ⇒ A'(5, -3)

Simplify Using Distributive Property
-6(2a + 8)
Answer:
-12a - 48
Step-by-step explanation:
you do -6 times 2a which is -12a then you do -6 times 8 which gives you -48 so you put -12a - 48
since the 48 is a negative we would just put a minus sign instead a plus. If it was a positive 48 we would put a plus sign buts its not so we put a negative.
[tex]\huge\boxed{\mathcal{HELLO!}}[/tex]
The distributive property states that
a(b+c)=ab+ac (we multiply a by everything inside the parentheses)
-6(2a+8)
-12a-48
[tex]\huge\boxed{Answer:-12a-48}[/tex]
Hope it helps!

9(m - 3) + 3m = 7m + 43
Answer:
m=14
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
M=14
Step-by-step explanation:
So distribute first
9m-27+3m=7m+43
Combine like Terms
12m-27=7m+43
Subtract 7m on both Sides
5m-27=43
Add 27 on both sides
5m=70
Iso,ate variable by dividing 5 on both sides
m=14

Answer:
[tex]g^{-1}[/tex] (x) = 8x + 48
Step-by-step explanation:
let y = g(x) and rearrange making x the subject, that is
y = [tex]\frac{x}{8}[/tex] - 6 ( add 6 to both sides )
y + 6 = [tex]\frac{x}{8}[/tex] ( multiply both sides by 8 )
8(y + 6) = x , distribute
8y + 48 = x
Change y back into terms of x with x = [tex]g^{-1}[/tex] (x) , thus
[tex]g^{-1}[/tex] (x) = 8x + 48
