Match the terms to their definition. 1. coefficient a rectangular array made up of rows and columns 2. determinant the form ax + by = c of a linear equation, where a, b, and c are integers 3. matrix the determinant found when column 1 consists of the x-coefficients and column 2 consists of the y-coefficients of a linear system 4. determinant form the value of: (row 1, column 1)(row 2 column 2) - (row 1, column 2)(row 2, column 1) in a 2 by 2 matrix 5. system determinant the determinant found when column 1 consists of the x-coefficients and column 2 consists of the constants of a linear system 6. x-determinant the determinant found when column 1 consists of the constants and column 2 consists of the y-coefficients of a linear system 7. y-determinant

there is no grid

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

answer: 0.64

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
