Plz fast plz i really need will award ! a triangular pyramid begins with its vertices locate at the following points: p(0, 5, 4), y(-2,7,4), r(0,7,4), and a(0,7,6). they pyramid is then reflected over the xz-plane. the reflected image is then translated 3 units back, 2 units left, and 4 units up. (a) write the general rule you use for the reflection. (b) show the results of your calculations for the reflection. (c) write the general rule you use for the translation. (hint: begin with the result of the rule for the reflection.) (d) show the results of your calculations for the translation

This is so hard and it’s for a test

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

Questions 9-10. use the table of educational expenditures to answer the questions. k-12 education expenditures population indiana $9.97 billion 6.6 million illinois $28.54 billion 12.9 million kentucky $6.58 billion 4.4 million michigan $16.85 billion 9.9 million ohio $20.23 billion 11.6million 9. if the amount of k-12 education expenses in indiana were proportional to those in ohio, what would have been the expected value of k-12 expenditures in indiana? (give the answer in billions rounded to the nearest hundredth) 10. use the value of k-12 education expenditures in michigan as a proportion of the population in michigan to estimate what the value of k-12 education expenses would be in illinois. a) find the expected value of k-12 expenditures in illinois if illinois were proportional to michigan. (give the answer in billions rounded to the nearest hundredth) b) how does this compare to the actual value for k-12 expenditures in illinois? (lower, higher, same? )
