ANSWER: 28
EXPLANATION:
Area is l • w or length • width. We know the width is 7 but for the length you only multiply the straight line. As 5 is slanted we use 4 instead, leaving us to multiply 7 • 4. This give us a solution of 28.

Answer:
The domain is -1 ≤x< 5
The range is -3≤y<3
Step-by-step explanation:
The domain is the values that x takes
The domain is -1 ≤x< 5
The range is the values that y takes
The range is -3≤y<3
There's nothing answered in that.
Answer:
The value of a is 10.
Step-by-step explanation:
We are given with the following pair of the linear system of equations below;
and .
Also, the solution is given as (a, -1).
To find the value of 'a', we have to substitute the solution in the equation because it is stated that (a, -1) is the solution of the given two equations.
So, the x coordinate value of the solution is a and the y coordinate value of the solution is (-1).
First, taking the equation;
Put the value of x = a and y = -1;
(-1) = -(a) + 9
a = 9 + 1 = 10
Now, taking the second equation;
Put the value of x = a and y = -1;
0.5a = 6 - 1
0.5a = 5
a = 10
Since we get the value of a = 10 from the equations, so the value of a is 10.
Y-intercept looks like -1.5 and slope is -1/4
