It has to be noted that there are several ways to factor the item. One of these is shown below.
The general form of a quadratic equation is,
Ax² + Bx + C = 0
where A and B are numerical coefficients and C is the constant. If we are to express the given equation in this form,
2x² - 5x - 88 = 0
The sum of the roots, x₁ and x₂ is -B/A and the product is equal to C/A.
Sum: x₁ + x₂ = -(-5/2) = 5/2
Product: x₁x₂ = -88/2 = -44
The values of x₁ and x₂ are 8 and -11/2.
The factors are (x - 8) and (x + 11/2)
<em>ANSWERS: 8 and -11/2. </em>
Answer:
y = -6/5x - 8
Step-by-step explanation:
Use the slope-intercept form y = mx + b and substitute slope(m) = -6/5 and the point (-5, -2). After that solve for b
y = mx + b
-2 = -6/5(-5) + b
-2 = 6 + b
-8 = b
For the equation substitute into y = mx + b ; y = -6/5x - 8
Answer:
P = 126; A = 927
Step-by-step explanation:
Enlarging by a scale factor means multiplying each number by the given. 6 x 4.5 = 27; 8 x 4.5 = 36. 2(27) + 2(36) = 126; 27 x 36 = 927.
The value of f(-3) for the function f(a) = -2a² - 5a + 4 is 1.
<h3>What are functions?</h3>
Function relates input and outputs. The outputs are called the ranges of dependent variables while the input are called domain or independent variables.
Therefore,
f(a) = -2a² - 5a + 4
Hence,
f(-3) = -2(-3)² - 5(-3) + 4
Therefore,
f(-3) = -18 + 15 + 4
f(-3) = -3 + 4
f(-3) = 1

<h2>circumference = 87.92ft</h2>
Step-by-step explanation:
radius (r) = 14ft
circumference = 2π×r
= 2 × 3.12 × 14
= 87.92ft
