<span>y=3x-12
2x-3y=-13
substitute </span>y=3x-12 into <span>2x-3y=-13
</span><span>2x-3y=-13
</span>2x-3(3x-12)=-13
2x - 9x + 36 = -13
-7x = -49
x = 7
y=3x-12 = y=3(7) -12 = 21 - 12 = 9
answer
solution
x = 7 and y = 9

Answer:
-26 :)
Step-by-step explanation:
Fill in y and x with the subs
do parentheses which is 6
6-8(4) - do 8 times 4 which is 32
then 6-32 which is -26
y < –12
Solution:
Step 1: Given inequality is y + 15 < 3.
To find the solution to the inequality.
Step 2: Subtract –15 on both sides to equal the expression.
⇒ y + 15 –15 < 3 –15
Step 2: Using addition identity property, any number adding with zero gives the number itself.
⇒ y + 0 < –12
⇒ y < –12
Hence the solution to the inequality is y < –12.
From the plot, the masses of the five smallest sodium chloride samples are all 1/4 ounce. Therefore, we can calculate for their total mass by multiplying the mass by 5:
total mass = 1/4 ounce * 5
= 5/4 or 1.25 ounces
We can get the same result even if we compute for the total mass by taking the sum of their masses:
total mass = 1/4 + 1/4 + 1/4 + 1/4 + 1/4
= 5/4 oz.
