Answer:
3x+5=2x+1
3x-2x=1-5
x= -4
3x + 5 = 2x + 1 | subtract 2x on both sides
x + 5 = 1 | subtract 5 on both sides
x = -4 | final answer

Answer:
y = -x + 9
Step-by-step explanation:
✔️Find the slope using (9, 0) and (7, 2):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 0}{7 - 9} = \frac{2}{-2} = -1 [/tex]
Slope (m) = -1
✔️Find the y-intercept (b):
The line intercepts the y-axis when y = 9. Therefore, y-intercept (b) = 9
✔️Substitute m = -1 and b = 9 into y = mx + b
Thus,
y = -1(x) + 9
y = -x + 9

A certain ball is dropped from 204 centimeters, and has a rebound factor of 72% (The height of the ball after each bounce is 72% of the height of the bounce before.). Which equation represents the relationship between the the number of bounces, n, and height, h, in centimeters? Group of answer choices
Answer:
The equation that represents the relationship between the number of bounces and the height is [tex]H = 204\cdot 0.72^{n}[/tex].
Step-by-step explanation:
According to this exercise, we notice that maximum height of the ball ([tex]H[/tex]), measured in centimeters, is reduced at geometric rate and as a function of the number of bounces ([tex]n[/tex]), with no unit, which is defined by geometric progression:
[tex]H = H_{o}\cdot r^{n}[/tex] (1)
Where:
[tex]H_{o}[/tex] - Initial height of the ball, measured in centimeters.
[tex]r[/tex] - Bounce factor, no unit.
If we know that [tex]H_{o} = 204\,cm[/tex] and [tex]r = 0.72[/tex], then the equation that represents the relationship between the number of bounces and the height is:
[tex]H = 204\cdot 0.72^{n}[/tex] (2)

work out the total value of the 20p coins give your answer in pounds(£)
Answer:
Approximately 25p (please change to pounds by yourself I'm not European, sorry).
Ok so according to my research its 100 pence to one pound. Which will mean that 25p in pounds is £ 00.25

A company that makes hair-care products had 6,000 people try a new shampoo. Of the 6,000 people,
36 had a mild allergic reaction. What percent of the people had a mild allergic reaction?
% of the people had a mild allergic reaction,
Answer:
0.6% of the people had a mild allergic reaction.
Step-by-step explanation:
Given that:
Number of people who tried hair care products = 6000
Number of people who had reaction = 36
Percent of people = [tex]\frac{Number\ of\ people\ with\ reactions}{Total\ number}*100[/tex]
Percent of people = [tex]\frac{36}{6000}*100[/tex]
Percent of people = 0.6%
Hence,
0.6% of the people had a mild allergic reaction.

Cube-shaped shipping boxes, like the one shown, are packed into a van. They form a solid without gaps or overlaps that is 3 feet long, 2 feet wide, and 3 feet tall. What is the volume of the solid formed?
Answer: 18 feet
Step-by-step explanation:
You didn't put the picture but based on your question, the volume would be calculated by multiplying the length by the width and the height. This would be:
= Length × Width × Height
= 3 × 2 × 3
= 18 feet
