Answers
Answer:
(- [tex]\frac{15}{2}[/tex], 25 )
Step-by-step explanation:
Given the 2 equations
y = - 4x - 5 → (1)
y = - 2x + 10 → (2)
Substitute y = - 2x + 10 into (1)
- 2x + 10 = - 4x - 5 ( add 4x to both sides )
2x + 10 = - 5 ( subtract 10 from both sides )
2x = - 15 ( divide both sides by 2 )
x = - [tex]\frac{15}{2}[/tex]
Substitute this value into either of the 2 equations and evaluate for y
Substituting into (2)
y = - 2(- [tex]\frac{15}{2}[/tex] ) + 10 = 15 + 10 = 25
Solution is ( - [tex]\frac{15}{2}[/tex], 25 )
Mr. Smith has an account balance of -$275.78. He deposits $539.20 into his account. What is Mr. Smith's account balance now? *
Answers
Answer:
$ 263.42
Step-by-step explanation:
-275.78 + 539.20 = 263.42
The new balance in Mr. smith account will be $263.42.
What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have Mr. Smith has an account balance of -$275.78. He deposits $539.20 into his account.
Assume that the new amount in his account will be [x]. Then -
[x] = 539.20 - 275.78
[x] = 263.42
Therefore, the new balance in Mr. smith account will be $263.42.

y = 3x - 2
x - y = 4
Answers
Answer:
x=-1, y=-5
Step-by-step explanation:
y=3x-2 (1)
x-y=4 (2)
sub (1) into (2)
x-(3x-2)=4
x-3x+2=4
-2x=2
x=-1
sub x=-1 into (1)
y=3(-1)-2
=-3-2
y = -5
Therefore: x=-1, y=-5 :))
Answer:
x = -1, y = -5
Step-by-step explanation:
y = 3x - 2
x - y = 4
x - y = 4
x - (3x - 2) = 4
x - 3x + 2 = 4
-2x + 2 = 4
-2x = 2
x = -1
x - y = 4
-1 - y = 4
-y = 5
y = -5
Check:
x - y = 4
-1 - (-5) = 4
-1 + 5 = 4
4 = 4

A dairy cow can produce up to 2,000 gallons of milk every 365 days. At this rate, a cow can produce x gallons of milk in 500 days. Which proportion should be used to find x
Answers
We find this by dividing 2000 by 365:
2000/365 = 5.4794 gallons of milk per day
Now, to find the amount of gallons she produces in 500 days, we simply multiply the number of gallons she produces in 1 day by 500:
5.4794 X 500 = 2,739.73 gallons in 500 days.

Answers
Answer: 5√10.
Step-by-step explanation:
250 is split into its prime factors as 2 * 5 * 5 * 5 which implies √250 = √(2 * 5 * 5 * 5). Now we can simplify this further by pulling out the number which is multiplied to itself. This gives √250 = 5 * √(2 * 5) = 5√10. Therefore the square root of 250 is √250 = 5√10.
(1.2÷0.375−0.2)/(6 4/25 ÷15 2/5 +0.8) = (0.016÷0.12+0.7)/x
Answers
Answer:
x=1/3
read below to find out how I solved!
Step-by-step explanation:
break it down.
First do 1.2÷0.375−0.2 = 1.2.
it is now 1.2/(6 4/25 ÷15 2/5 +0.8) = (0.016÷0.12+0.7)/x
now do 6 4/25 ÷15 2/5 +0.8 = 3
it is now 1.2/3 = (0.016÷0.12+0.7)/x
now do 0.016÷0.12+0.7 and that is 5/6
now you have 1.2÷3 = 5/6 ÷ x
solve for x and you should get x = 1/3!!

Answer:
A. x ≥ -3 and x < 2, or -3 ≤ x < 2
Step-by-step explanation:
Remember solid dot means include, open dot means not include.
x ≥ -3: this means x is greater and equal (includes) -3.
x < 2: this means x is less than 2 and does not include it.
Answer:
A
Step-by-step explanation:
So on the number line you see a closed circle at -3 and an open circle at 2.
Closed circle represents it's either [tex]\leq[/tex] or [tex]\geq[/tex]. Open circle represents < or >.
So the first part has a closed circle at -3 and goes towards the right side. Since it does that, it would be [tex]x \geq -3[/tex].
The second part has an open circle at 2 and goes towards the left side. Since it does that, it would be [tex]x < 2[/tex].
To combine it together, it would get [tex]-3 \geq x < 2[/tex].
Since option A is [tex]x \geq -3[/tex] and [tex]x < 2[/tex], or [tex]-3 \geq x < 2[/tex], A would be the answer.

Answer:
∠ DBC = 16°
Step-by-step explanation:
∠ ABD + ∠ DBC = ∠ ABC , substitute values
2x + 15 + x - 30 = 123 , that is
3x - 15 = 123 ( add 15 to both sides )
3x = 138 ( divide both sides by 3 )
x = 46
Thus
∠ DBC = x - 30 = 46 - 30 = 16°
