Answer:
Jennie is 6 2/3
Sammie is 11 2/3
Step-by-step explanation:
Let s represent Sammie's age now. Then Jennie's age now is s-5. Their ages 5 years ago had the relation ...
(s) -5 = 4((s-5) -5)
s -5 = 4s -40
35 = 3s . . . . . . . add 40-s to both sides
35/3 = s = 11 2/3 . . . . divide by 3
si -5 = 11 2/3 -5 = 6 2/3
Sammie is 11 2/3, and Jennie is 6 2/3 now.
_____
Check:
Five years ago, their ages were 6 2/3 and 1 2/3 = 20/3 and 5/3. Sammie was 20/5 = 4 times as old as Jennie then, as required.
_____
Alternate solution
The difference in ages remains constant, so it was the same 5 years ago. Sammie was 4 times Jennie's age at that time, so the difference in their ages was 3 times Jennie's age. That is, 5 years was 3 times Jennie's age at that time, so Jennie was 5/3. At present, Jennie is 5/3 +5 = 20/3 = 6 2/3, and Sammie is 5 years older, so 11 2/3.
Find the equation of the line through point (−3,8) and perpendicular to y=27x+117.
Answer:
y - 8 = (-1/27)(x + 3)
Step-by-step explanation:
the slope of a line perpendicular to the given y = 27x + 117 is the negative reciprocal of 27, that is, -1/27. Using the point-slope form y - k =m(x - h) to write the new equation, we get:
y - 8 = (-1/27)(x + 3)

Write an equation of the line that passes through (−4,−5) and is parallel to the line y=−4x−1.
Equation: y=
Answer:
step 1. y - y1 = m(x - x1). This is the standard line equation given a point and a slope.
step 2. parallel lines have the same slope so the slope is -4.
step 3. y - (-5) = -4(x - (-4)).
step 4. y + 5 = -4x - 16.
step 5. y = -4x - 21.

PLEASE HELP!!!!!!!!!!!!!!!
I would say it would be 55 and if this question.If you get the answer incorrect my apologies
Step-by-step explanation:
40 + y + y + 30 = 180
2y + 70 = 180
2y + 70 (-70) = 180 (-70)
2y = 180 - 70
2y = 1102y/2 = 110/2
y = 110/2
y = 55

1 cm
The longest side on the shape is 12 cm
Work out the value of x.
Answer:
The value of x must be 6. Because as it is said that the longest side of this shape is 12 therefore, if 2 is multiplied with 6 one of tge sides is 12, which is the biggest.

Answer:
between 17 and 18
Step-by-step explanation:
x² = 315
To find the range that the value is in, you need to know the perfect squares before and after 315.
17² = 289
18² = 324
289 < 315 < 324
This means √315 is between 17 and 18.

Select all ordered pairs that correspond to input-output pairs of the function y = −7x + 6.
Answer:
There are no options, so i will answer in a general way.
In a function:
y = f(x)
The output is y, and the input is x, and the ordered pair is written as (x, y)
In this case, we have the function:
y = -7*x + 6
Then we need to have different inputs and then find the outputs for each.
For example, if x = 1.
y = -7*1 + 6 = -1
Then we have the ordered pair (1, - 1)
if x = 0
y = -7*0 + 6 = 6
then we have the ordered pair (0, 6)
The general ordered pair is written as:
(x, y = -7*x + 6)
or:
(x, -7*x + 6)
Where you only need to replace the value of x.

x = 37 1/2x = 2Step-by-step explanation:
Parallel lines divide transversals proportionally. I like to write the proportions so the variable is in the numerator. Then the solution is obtained by multiplying by the denominator of the variable term.
1. x/20 = (46 -16)/16
x = 20(30/16)
x = 37.5

2. (x +4)/13.5 = 4/9
x +4 = 13.5(4/9) = 6
x = 6 -4

Write the equation in slope-intercept form. Write the numbers in the equation as proper fractions, improper fractions, or integers.
Answer:
Step-by-step explanation:
f(x) = -3x-6
slope of line is -3
parallel lines have the same slope
point-slope equation for line of slope -3 that passes through (6,-8):
y+8 = -3(x-6)
put equation into slope-intercept form:
y = -3x + 10
Answer:
[tex]y = - 3x + 10[/tex]
Step-by-step explanation:
We are asked to find a line parallel to line f
[tex] - 3x - 6[/tex]
and passes through 6,-8.
Parallel lines have the same slope so our new line will also has-3 as it slope
wo using the slope intercept form let update our equation so far.
Slope intercept is
[tex]y = mx + b[/tex]
where m is the slope and b is the y intercept
plug in -3 for the slope since our new equation must be parallel.
[tex]y = - 3x + b[/tex]
Now plug 6 for x and -8 for y.
[tex] - 8 = - 3(6) + b[/tex]
[tex] - 8 = - 18 + b[/tex]
[tex]b = 10[/tex]
Our equation is
[tex]y = - 3x + 10[/tex]
