Answer:

The answer should be -4a-1. This is because you have to open the box.

-(-10a+13)

Two negatives become positive so she should have had -14+10 to make -4 and 12-13 to make -1. A negative and positive together, the negative always wins so that why you subtract.

Answer:

b. the cost of 4 sandwhiches is $8

Step-by-step explanation:

A. The domain is all of the possible x values (the range is all of the y values)

B. By finding the x value of 4 you can then trace it up until it intersects with the slope or your data points. Then you look left and see which y-value is associated with the x-value.

Helloo!!! please help me on this !!!!
ivann1987 [24]

It is given that ️PQR & ️UVW are congruent to each other. According to CPCT, the corresponding angles in 2 triangles willl have the same measure. So, ∠R = ∠W, i.e, (10x - 18)° = 8x°

\mathfrak{10x - 18 = 8x}

\mathfrak{10x - 8x = 18}

\mathfrak{2x = 18}

\mathfrak{x = \dfrac{18}{2}}

\underline{\mathfrak{x = 9}}

Measure of ∠R :

\mathfrak{8x}

\mathfrak{8(9)}

\boxed{\mathfrak{72^{\circ}}}
