Answer:
a = 6 b= 7
Step-by-step explanation:
4 (b-1) = 3b + 3 substitue for a
4b - 4 = 3b + 3 subtract 4b from both sides
-4 = 3b + 3 - 4b = -4 = -b + 3 combine 3b and (-4b)
-7 = -b divide by -1 for both sides
7 = b
4a = 3 × 7 + 3 substitute for b
4a = 24 combine like terms
a = 6 divide by 4 on both sides
a = 7 -1
a = 6
Answer:
Given the system of equation:
g +h = 9 ......[1]
8g + 7.5h = 71 ......[2]
We can write equation [1] as;
g = 9-h ......[3]
Now, substitute equation [3] in [2] we get;
Using distributive property i,e 
.
72 - 8h +7.5h = 71
Combine like terms:
72 - 0.5 h = 71
Subtract 72 to both sides of an equation:
72 - 0.5 h -72 = 71-72
Simplify:
- 0.5 h = -1
Divide both sides by -0.5 we get;
Simplify:
h = 2
Substitute the value of h =2 in equation [3] to solve for g;
g = 9 - 2 = 7
g = 7
Therefore, the solution for the given equation is :
g = 7 and h = 2
Answer:
Part 1) Is a cubic expression
Part 2) The quadratic expression is 12x² + 8x − 1
Step-by-step explanation:
Part 1) Classify the expression: 5x³ + 2x − 3
we know that
Polynomials can be classified two different ways - by the number of terms and by their degree.
so
a) <u>By the number of terms</u> is a trinomial, because has three terms
b) <u>By their degree</u> The degree of the polynomial is found by looking at the term with the highest exponent on its variable
The highest exponent is 3 so this is a 3rd degree trinomial
therefore
Is a cubic expression
Part 2) Choose the expression that represents a quadratic expression
we know that
If the expression is a quadratic equation , then the highest exponent of the variable is 2
therefore
The quadratic expression is 12x² + 8x − 1
Answer:
A 5 by 5 Power in Trust is a clause that lets the beneficiary make withdrawals from the trust on a yearly basis. The beneficiary can cash out $5,000 or 5% of the trust's so-called fair market ...
Step-by-step explanation:
5^5
=5*5*5*5*5
=5^5
=3125
I'd say option D because you can just tell right off the bat that if x = 0, then f(x) = 43.75.
