Answer:
Step-by-step explanation:
178-10+3(25+1)2
We need to use order of operation (Pemdas).
P-Parenthesis
e-Exponents
m- Multiplication
d- Division
a- Addition
s-Subtract
178-10+3(25+1)2
178−10+3(25+1)(2)
=168+3(25+1)(2)
=168+(3)(26)(2)
=168+(78)(2)
=168+156
=324
The answer chooses give are not close to 324 but we need to pick a expression tat is equivalent.
Equivalent means equal in value.
None of these answer choose are equal to 324
Answer: The correct answer is Choice A (6, -1).
Since we have the slope and the equation, we can find the y-intercept and write the equation of the line.
y = -0.75x + b
5 = -0.75(-2) + b
5 = 1.5 + b
b = 3.5
Therefore, the equation is y = -0.75x + 3.5.
Now, just plug in the points until one of that satisfies the equation. The point (6, -1) will satisfy the equation.
For the numeric part, you'll have to find the GCD of 15 and 25, which is 5. So, we can factor a 5 and we have
As for the literal part, you can factor because it's the power of s with the smallest denominator. So, we have
Answer:
4
Step-by-step explanation:
Because the powers have the same base of 2, we can apply the index law:
Therefore,
<u>Part A:</u>
lines y=-2x+9 and 4x+2y=4 can be used to create a system of equation that has no solution because none of the lines intercept on a graph.
<u>Part B:</u>
lines y=2x+2 and 6x-3y=6 can be used to create a system of equation that has infinitely many solutions because again none of the lines intercept on a graph
<u>Part C:</u>
The lines y=1/2x+1 and 4x+2y=4 can be used to create a system of equations with one solution because on a graph both lines intersect at one point.
The Graphs Are Shown Below.
