Answer:
p= 24
4p= 4(6) = 24
In a simplier way, 4 times 6
Step-by-step explanation:
Okay. So 3 guests are free. Mika has $42 dollars she can spend with $7 per guest. 42/7 = 6. Add the 3 other guests and you get 9. Mika can bring 3 guests with her to the gym. D gives the correct answer, and A and B give out the correct equations as well. C is not right, because 7 * 9 is 63. 63 - 3 is 60. 60 > 42. C is the incorrect equation. The answer is C.
63. The ratio 63:9 is equal to 21:3 because 3x3 is 9 and 21x3 is 63
Slope-intercept form of a line:
y=mx+b
m=slope
other perpendicular line to this line (y=mx+b) will have the next slope:
m´=-1/m
We have this line in slope-intercet form:
y=1/3x-7
m=1/3
A perpendicular line will have the next slope:
m´=-1/m=-1(1/3)=-3
Now, we have a point (5,-2) and the slope (-3).
point-slope form: given a point (x₀,y₀) and the slope m, the point-slope form will be:
y-y₀=m(x-x₀)
In this case:
y-(-2)=-3(x-5)
y+2=-3x+15
y=-3x+15-2
y=-3x+13
Answer: The equation of a line (slope intercept form) that is perpendicular to the line y=1/3x-7 and passes throught the point (5,-2) is:
y=-3x+13
Answer:
Question #3: Answer = 31
Step-by-step explanation
• Plug in 3 for x
• Plug in -4 for y
| -3(3)² + 2(-4) | -(3)(-4)
From here, simplify. Don't forget to use PEMDAS!
| -27 +8 | + 12
| -19 | + 12
19 + 12
31
Use this same method to solve for Question #2!
