Question
what is the solution of the system of equations? y=-4x+10 y=-2x-6
ANSWER-
y = -4x + 10
y = -2x - 6
-4x + 10 = -2x - 6
-4x + 2x = -6 - 10
-2x = -16
x = -16/-2
x = 8
y = -4x + 10
y = -4(8) + 10
y = -32 + 10
y = -22
solution is (8,-22)

Answer:
3 batters
Step-by-step explanation:
For the past data, we have observed that:
15 batters have gotten a hit
5 batters have not
The total of batters that we have observed is
n = 15 + 5 = 20
Therefore, this means that based on the observed data, the probability that a batter gets a hit is:
where
n(h) = 15 is the number of batters that got a hit
After that, we want to know how many batters we will expect to get a hit in the next 4 batters. We can write it as:
And since
p(hit) = 0.75
We find:
So, we expect 3 batters to get a hit in the next 4.
<span>Use the distributive property to rewrite each algebraic expression: Do not solve, just rewrite.
1) 8(x + 7) = 8x + 56
2) 5(x - 10) = 5x - 50
3) 6(11 + x) = 66 + 6x
</span><span>Factor each expression. (Pull a common factor from each number)
COMPLETED EXAMPLE: 27 + 12 = 3(9 + 4) → (3 is the shared factor for 27 and 12)
4) 12 + 36 = 12 (1 + 3)
5) 16 + 20 = 4 (4 + 5)
Solve each expression using the distributive property.
6) 4 x 82 = 4 (80 + 2) = 320 + 8 = 328
7) 12 x 44 = 12 (40 + 4) = 480 + 48 = 528

Expression = 9f + 9n = 9($2.50) + 9($4)
Total cost =</span>9($2.50) + 9($4) = $22.5 + $36 = $58.5
