Answer:
X<2
Step-by-step explanation:
2x+4<8
subtract 4 from both sides
2x+4-4<8-4
simplify
2x<4
divide both by 2
2x/2<4/2
x<2
Answer:
Given
no of Grade 6 students = 220
no of Grade 7 students = 40 more than grade 6 students
Step-by-step explanation:
boys Grade 7 students = no of Grade 6 students - 40 more than grade 6 students
boys Grade 7 students = 220 - 40
boys Grade 7 students = <u>180 grade 7 boy students are enrolled</u>
Therefore, 180 grade 7 boy students are enrolled.
1.B - - original function is y = sqrt(x). If we make sqrt(x+4), we will move the original function to the left 4. If we make sqrt(x+4)+3, additionally the original function will be moved up 3.
2.D - original function is y = sqrt(x). If we make sqrt(x-7), we will move the original function to the right 7. If we make 5*sqrt(x-7), additionally the original function will be expanded throw the y-axis.
3.E - original function is y = x^5. If we make -x^5 (multiply x^2 by -1), we will reflect the original function over the x-axis. If we make -x^5 - 4 , we additionally will move the original function down 4.
4.C - original function is y = x^2. If we make (x-3)^2, we will move the original function to the right 3. If we make x^2 - 5 , we will move the original function down 5.
5.A - original function is y = x^2. If we multiply x^2 by 1/3, function will be compressed about the y-axis.
