The line which is perpendicular to 2x + 14y = 70 mus have a slope of 7/2.
What is a linear function?A linear function is in the form:
y = mx + b
Where m is the slope and b is the y intercept
Two lines are perpendicular if the product of there slope is -1
Given the line:
2x + 14y = 70
14y = -2x + 70
y = (-2/7)x + 70
The line which is perpendicular to 2x + 14y = 70 mus have a slope of 7/2.

2. Ms. Kay did a T-shirt competition to see what shirt to order the 4 graders. There were 48 responses. 75% voted for the black T-shirt.
What is the whole?
What is the percent?
What is the part?
How would you use this formula, part=percent x whole to find the missing information?
Hint: Don't forget to turn
your part into a decimal.
PLEASE show Step by Step in order please! Or take a picture thank you all sm !!!!
Answer:
The whole = 48
The percentage = 78%
The part = 37.44
Step-by-step explanation:
The given parameters are;
The number of responses for the competition = 48 responses
The percentage that voted for the black T-shirt = 75%
The whole = The total number of responses for the competition = 48
The percentage = 78% = The part/(The whole) × 100
The part = The missing information
To find the part, we substitute the values of the whole, and the percentage into the given following equation
The part = The percent × The whole
∴ The part = 78% × 48 = 78/100 × 48 = 37.44
The part = 37.44.

Find the measure of angle A
can you show me how to solve this problem
Answer:
A = 20 degrees
Step-by-step explanation:
Both legs of the triangles are 2x and equal, so we know that the triangle is isoceles. That means both acute angles are equal as well.
In a triangle there are 180 degrees
180 - 140 = 40
40 remainding degrees/ 2 equal angles
A = 20 degrees
Answer:
angle a = 20
Step-by-step explanation:
So like the person above me said
180-140=40
40 divided by 2 is 20

Q.2 Find the equation of the straight line passing through the A(-2, -4) and B(1, -7). (3)
Q.3 Find the equation of the straight line passing through (3, 5) and parallel to the line y = 2x+ 3 (2)
Q.4 Find the equation of the straight line passing through (5, 7) and gradient 3
Answer:
See answers below
Step-by-step explanation:
Standard equation of a line is expressed as y = mx+b
m is the slope
b is the y intercept
Given the coordinate points (-2, -4) and B(1, -7)
Slope m = y2-y1/x2-x1
m = -7-(-4)/1-(-2)
m = -7+4/1+2
m = -3/3
m = -1
Get the intercept
Substitute m = -1 and (1, -7) into y = mx+b
-7 = -1(1) + b
-7 = -1 + b
b = -7+1
b = -6
Get thw equation
y = mx+b
y = -x + (-6)
y = -x - 6
Q.3 The equation in point slope form is expressed as y - y0 = m(x-x0)
Given the point (3, 5)
x0 = 3
y0 = 5
Given the equation y = 2x+3
mx = 2x
m = 2
slope = 2
Substitute the slope and the point in the expression
y - 5 = 2(x -3)
y - 5 = 2x - 6
y - 2x = -6 + 5
y - 2x = -1
This gives the required equation
Q.4 The equation in point slope form is expressed as y - y0 = m(x-x0)
Given the point (5, 7)
x0 = 5
y0 = 7
Slope = 3
Substitute the slope and the point in the expression
y - 7 = 3(x -5)
y - 7 = 3x - 15
y - 3x = -15 + 7
y - 3x = -8
This give the required equation

Step-by-step explanation:
-80 and -110
It is an arithmetic sequence. The difference = -30. It is the difference between each number in the sequence: 10-40=-30
-50-30=-80
-80-30 =-110
-80
First Identify the sequence being made here.
10-40 = -30
-20-10 = -30
-50-(-20) = -30
Therefor this pattern is decreasing by a rate of 30 so to continue this, just subtract 30 from -50.
-50-30 = -80
The next term is -80.

Which angles are supplementary to each other? Select all that apply. 3 and 2, 4 and 5, 1 and 2, and/or 4 and 3
Answer:
<1 and <3
<1 and <4
<2 and <1
<2 and <3
Step-by-step explanation:
Find the diagram attached
First know that supplementary angles are angles that sums up to 180degrees. Since the sum of angles on a straight line is also 180degrees, then the pair of supplementary angles must lie on the same straight line.
According to the given diagram, the following angles are supplementary since they lie on the same straight line;
<1 and <3
<1 and <4
<2 and <1
<2 and <3
The sum of all the pair of angles is 180 degrees

Answer:
Distance between mall and library is 6.32 miles.
Step-by-step explanation:
Coordinates of the door to the library is at (2, 4) and door to the mall is at (8, 4).
Since, distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Distance = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
By this formula,
Distance between (2, 4) and (8, 4) will be,
Distance = [tex]\sqrt{(8-2)^2+(2-4)^2}[/tex]
= [tex]\sqrt{36+4}[/tex]
= [tex]\sqrt{40}[/tex]
= 6.32 miles

The population of the random town is 750,000 and 23% of the population becomes a zombie everyday, what function represents p, the number of unaffected people after x days?
Given:
The initial population = 750,000
23% of the population becomes a zombie everyday.
To find:
The function that represents p, the number of unaffected people after x days.
Solution:
The general exponential decay function is:
[tex]P=P_0(1-r)^x[/tex] ...(i)
Where, [tex]P_0[/tex] is the initial population, r is the rate of decay and x is the time period.
We know that,
The initial number of unaffected people = 750,000
The unaffected people decreasing by 23% . The decimal form of 23% is 0.23.
Putting [tex]P_0=750000, r=0.23[/tex] in (i), we get
[tex]P=750,000(1-0.23)^x[/tex]
[tex]P=750,000(0.77)^x[/tex]
Therefore, the required function is [tex]P=750,000(0.77)^x[/tex], where p is the number of unaffected people after x days.
