The answer is : y = 2x + 50
because you multiply 2 with x and u add 50 since you started from 50.
for example y = 2(5) + 50
y = 10 + 60
= 70

The perimeter is just the sum of all the side lengths, so you have

$P=2.8+3.4+10.8+7.1+4.5+8.2=36.8$

Kevin is 4 times as old as Daniel and is also 6 years older than Daniel

MAXImum [283]

Answer:

Part a) Daniel's age is 2 years

Part b) Kevin's age is 8 years

Step-by-step explanation:

The question is

Part a) How old is Daniel?

Part b) How old is Kevin?

Let

x ----> Kevin's age

y ----> Daniel's age

we know that

$x=4y$ -----> equation A

$x=y+6$ ----> equation B

Equate equation A and equation B

$4y=y+6$

solve for y

$4y-y=6$

$3y=6$

$y=2$

therefore

Daniel's age is 2 years

Find the value of x

substitute the value of y in any of the two equations

$x=4(2)=8\ years$

$x=2+6=8\ years$

therefore

Kevin's age is 8 years

Help me please FOR A GRADE ‼️ What is an equation of the line that is parallel to Y=4x-1 one and that passes through the point -

Sliva [168]

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0, or (0,y))

For lines to be parallel, their slopes have to be the SAME.

The given line's slope is 4, so the parallel line's slope is also 4.

y = 4x + b

To find "b", plug in the point (-3,5) into the equation.

y = 4x + b

5 = 4(-3) + b

5 = -12 + b Add 12 on both sides

17 = b

y = 4x + 17
