Answer:
x = 71
Step-by-step explanation:
<B is a right angle, so triangle ABE is a right triangle, and angles BAE and AEB are complementary.
m<BAE + m<BEA = 90
42 + m<BEA = 90
m<BEA = 48
<BEC is a straight angle, so its measure is 180 deg.
m<CED + m<DEA + BEA = 180
61 + x + 48 = 180
x + 109 = 180
x = 71
For both of the first two parts, you've left out part of the question and no answer is possible. / / / For the last one, ... u + xy = 18 + (10)(8) = 18 + 80 = 98.
For f(x), the function uses the following formula:
The y-intercept in this formula is represented by c.
f(x) has a c value of -4, so the y-intercept of f(x) is -4.
For g(x), the y-intercept is found when the graph cross the y-axis.
g(x) cross the y-axis at y = 0, so the y-intercept of g(x) is 0.
For h(x), the y-intercept is found by taking the output at x = 0.
At x = 0, the y value that is output is -2, so the y-intercept is -2.
Compare the three y-intercepts:
The function with the greatest y-intercept is g(x), with a y-intercept of 0.
The statements can be used to describe the original functions f(x) and g(x) are; Option B
<h3>How to interpret function graphs?</h3>
Let the functions be
f(x) = ax + b
g(x) = cx + d
Their sum is;
j(x) = (a + c)x + b + d
Their product is;
k(x) = (ax + b)(cx + d)
From the graph, we see that;
f(x) = x + 6
g(x) = -2x² + 8
f'(x) = 1
g'(x) = -4x
