Hey!!
If h(x) =7x + 3x^2 and u want h(4)
U just do this x=4
h(x) =7x + 3x^2 , x=4
h(4) =7x4 + 3x4^2
h(4) =28 + 3x4^2
h(4) =28 + 48
h(4) =76 , i think that’s it

(b) 21 is 35% of what?
Answers
Answer:
a) 68
b)60
Step-by-step explanation:
a) 85% = 0.85
0.85 * 80 = 68
b) let x be the unknown number.
35% = 0.35
0.35x = 21
x = 60
Answer:
Step-by-step explanation:
a, 85% of 80
85% of 80
= 85/100*80
=85/100*80
=0.85*80
=68.
b, 21 is 35%
21 is 35%
=21*35/100
=21*0.35
=7.35.

Use the information given to write an equation in standard form.
6. Slope is 3, and (1. 4) is on the line.
7. Slope is -2, and (4,3) is on the line.
10. Slope is , and (1, 3) is on the line.
11. Slope - , and (2, 3) is on the line
Answers
6. 3x-y=-1
In slope intercept form this equation has a slope of 3 and point 1,4 is included on the graphed line: y=3x+1 is slope intercept form.
7. 2x+y=11
In slope intercept form this equation has a slope of -2 and point 4,3 is included on the graphed line: y=-2x+11 is slope intercept form
10. 4x-7y=-17
In slope intercept form this equation has a slope of 4/7 and point 1,3 is included on the graphed line: y=4/7x+17/7 is slope intercept form
11. 3x+2y=12
In slope intercept form this equation has a slope of -3/2 and point 2,3 is included on the graphed line: y=-3/2x+6 is slope intercept form
You basically just find the slope intercept form of each question then convert the intercept form over to standard form then graph in intercept form to see if the point lies on the line :)

I really need help finding the solution!!
Answers
Answer:
-0.5 is not a solution
2 is a solution
Step-by-step explanation:
To check if something is a solution of the equation, you need to substitute the value in place of the variable
15 + 2y = -12 - 4y
15 + 2(-0.5) = -12 - 4(-0.5)
15 - 1 = -12 + 2
14 ≠ -10 ∴ -0.5 is not a solution
5 - 2(3x + 5) = 3 - 10x
5 - 2[3(2) + 5] = 3 - 10(2)
5 - 2(6 + 5) = 3 - 10(2)
5 - 12 - 10 = 3 - 120
-17 = -17 ∴ 2 is a solution
