Answer:
The x-intercept is 4
Step-by-step explanation:
We are given;
The slope of a line as -3/4
y-intercept is 3
We are supposed to determine the x-intercept;
We need to know that;
The slope of a line is given by the ratio of the change in y to the change in x
The coordinates of y-intercept are (0, 3)
Taking the x-intercept as a, then the coordinates of x-intercept is (a, 0)
But;
slope = Δ in y ÷ Δ in x
Therefore;

Solving for a

Therefore, the x-intercept is 4
Answer:
The percent attendance for that semester was 30%.
Step-by-step explanation:
In this problem, out of 190 students, only 57 students had perfect attendance. When a question says something like this, then it means that you are going to use division. You are going to divide 57 by 190.
57 ÷ 190 = 0.3
Now, multiply 0.3 by 100 to get the percentage.
0.3 * 100 = 30
So, the percentage of the perfect attendance is 30%.
Because the triangle is only rotated, AB and A'B' would be equal. 8 in.
Answer:
X= 13
