Answer:
a = 7
Step-by-step explanation:
8a - 4 = 3 + 7a export like terms to the same side of the equation
8a - 7a = 3 + 4 add like terms (the expressions will change sign when exported like when it's a negative expression it will be positive and vice versa.)
a = 7
The <em>correct answer</em> is:
1 3/4
Explanation:
We read 1.75 as "one and 75 one-hundredths." This tells us that it can be written as:
To simplify the fraction, we see that 25 goes into the numerator and denominator. We divide both by 25:
The simplified answer is 1 3/4.
Answer:
A. (0,2) and (7,23)
Step-by-step explanation:
To solve, we set both equations equal to each other (because both equations equal y).
3x + 2 = x^2 -4x + 2
x^2 - 7x = 0
x(x-7)
so the x values are 7 and 0.
Plugging x back into the linear equation (because it’s easier)
3(7) + 2 = 23
3(0) + 2 = 2
so the answers are (7, 23) and (0,2)
The similarities are they are all quadrilaterals. the differences are a rectangle has two different sets of equal side, a square sides are all right angles all the same size, and a rhombus has opposite equal acute angles.
