Answer:
569/
9 x^2−153xy−12y
Step-by-step explanation:
3/4 is equal to .75 so you multiply 9 by .75 to get the remaining fourth. 9 times .75 is 3 add 3 to 9 to get the whole amount of flour. 3+9= 12. Molly needs 12 cups of flour to make the bread.
Answer:
you would simply add 87 and 58 so 145
Step-by-step explanation:
<span>We all know that the interior angles of a triangle sums up to 180</span>°. To get the missing angle, we simply subtract the sum of the given angles from 180°
<span>
Similar triangles have the same measure of angles.
Triangle 1: 80°, 62° </span>→ 180 - 80 - 62 = 38°<span>
Triangle 2: 62°, 38° </span>→ 180 - 62 - 38 = 80° SIMILAR TRIANGLES<span>
Triangle 1: 29°, 47° </span>→ 180 - 29 - 47 = 104°<span>
Triangle 2: 91°, 76° </span>→ 180 - 91 - 76 = 13° NOT SIMILAR<span>
Triangle 1: 100°, 45° </span>→ 180 - 100 - 45 = 35°<span>
Triangle 2: 25°, 45° </span>→ 180 - 25 - 45 = 110° NOT SIMILAR
Answer:
Part A: The equations are:
y = -1/2x + 2, and
y = 3x - 5
Part B: The solution is (2,1)
Step-by-step explanation:
Part A: There are two equations we need to find, each line is the graph of a function.Graphs are written in y = mx + b, m is the slope, which is the change in y divided by the change in x, and b is the y - intercept. To find the function of the first graph, the one going slightly down, the slope is: y goes down by one, and x increases by 2, so change in y/ change in x is -1/2. The y - intercept is where the graph goes through the point where x is 0, on this graph, the point is (0,2), the y - intercept is 2, so y = mx + b is y = -1/2x + 2
For the other equation, slope is when y increases by 3, x increases by 1, so 3/1, or 3. The y - intercept is -5, so y = 3x + (-5), or y = 3x - 5
Part B: The solution to this equation is the point where both of the functions meet, here, this point is (2,1), y is 2 and x is 1.
