Answer:
80 students
Step-by-step explanation:
10 to 1 figure
8 x 10 = 80
336
Step-by-step explanation:
because if the store needed 16 yards of fabric to make 5 witch's costumes then for 105 the store need 336 yards
so it's 105÷5=21 then
21×16=336 that's it
Answer:
y=2x-3
Step-by-step explanation:
The slope-intercept form of the original equation would be y=3/8−x/2
Therefore, the slope of the perpendicular line would be m=2
Then, the y-intercept would be 7=(2)x(5)+a
A=-3
Answer:
y=2x+3
Given the next quadratic function:

to sketch its graph, first, we need to find its vertex. The x-coordinate of the vertex is found as follows:

where <em>a</em> and <em>b</em> are the first two coefficients of the quadratic function. Substituting with a = 2 and b = 3, we get:

The y-coordinate of the vertex is found by substituting the x-coordinate in the quadratic function, as follows:

The factorization indicates that the curve crosses the x-axis at the points (-2, 0) and (1/2, 0). We also know that the curve crosses the y-axis at (0,-2). Connecting these points and the vertex (-0.75, -3.125) with a U-shaped curve, we get:
Answer:
y=11/5
Step-by-step explanation:
first divide by 5 on both sides
y+2/5=-13/5
subtract 2/5 on both sides to isolate the y
y=11/5
