Which table and graph represent the equation y = 4x?
A. Table A and graph B
B. Table B and graph A
C. Table A and graph A
D. Table B and graph B
The table and graph that represents the equation y = 4x are (D) table B and graph B
From the tables, we have:
Table A: (x,y) = (4,1), (8,2) and (12,3)
Table B: (x,y) = (1,4), (2,8) and (3,12)
From the above highlights, we can see that the y values of table B is 4 times its x values.
So, the equation of table B is:
y = 4x
The above illustration is applicable to graph B
Hence, the table and graph that represents the equation y = 4x are (D) table B and graph B

he vector projection of #vecu# onto #vecv# is
#=(vecu.vecv)/(||vecv||^2)*vecv#
The dot product is
#vecu.vecv=<3,15>.<-1,5>=-3+75=72#
The modulus of #vecv# is

PLEASE HELP I WILL MARK YOU BRAINLIEST determine the exact and approximat solutions for 4(x + 5)^2 = 21 show your steps
Answer:
x = − 5 + 1/2 √ 21 or x = − 5 + − 1/2 √ 21
Step-by-step explanation:
Let's solve your equation step-by-step.
4(x+5)^2=21
Step 1: Simplify both sides of the equation.
4x^2+40x+100=21
Step 2: Subtract 21 from both sides.
4x^2+40x+100−21 =21−21 4x^2+40x+79=0
For this equation: a=4, b=40, c=79
4x^2+40x+79=0
Step 3: Use quadratic formula with a=4, b=40, c=79.
x= −b±√ b^2−4ac/2ax
= −(40)+√ (40)^2−4(4)(79)/2(4)
x = 40^2±√ 336/8
x= −5+1/2 √ 21 or x = −5+ − 1/2√ 21
Answer: x = − 5 + 1/2 √ 21 or x = − 5 + − 1/2 √ 21

Answer:
95.40 total and 5.40 in intreset
Step-by-step explanation:
Answer:
A = $95.40
I = A - P = $5.40
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
A = 90(1 + (0.06 × 1)) = 95.4
A = $95.40
The total amount accrued, principal plus interest, from simple interest on a principal of $90.00 at a rate of 6% per year for 1 years is $95.40.
