Answer:
Step-by-step explanation:
8x + 1 = 5x + 22
8x - 5x + 1 = 5x- 5x + 22
3x + 1 = 22
3x + 1 - 1 = 22 - 1
3x = 21
x = 7
The equation of a straight line is 3x+2y=18
The point where the line crosses the x-axis is (__,__)?
Answer:
(6,9)..it crosses the x-axis at point 6
Step-by-step explanation:
3x+2y=18
First find the x and y intercept
a) To find x intercept, let y=0
which is 3x+2(0)=18
3x+0=18
3x=18..... divide both sides by 3
x=6
b) To find y intercept, let x=0
which is 3(0)+2y=18
0+2y=18
2y=18...... divide both sides by 2
y=9
The x-intercept of the line is the point at which the line crosses the x-axis.
The x-intercept is given as:
y = 0.
The point where the line crosses the x-axis is at x = 6.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The equation of a straight line is 3x+2y = 18.
The x-intercept of the line is the point at which the line crosses the x-axis.
The x-intercept is given as:
y = 0.
Substitute y = 0 in 3x + 2y = 18.
Now,
3x + 2y = 18
3x + 2 x 0 = 18
3x + 0 = 18
3x = 18
Dividing both sides by 3.
x = 18/3
x = 6
The x-intercept is at x = 6.
Thus,
The point where the line crosses the x-axis is at x = 6.

Paul buys a package of stickers for 1.50. There are 75 stickers in the package. What is theme unit cost per sticker?
Answer:
The unit cost is: 0.02 $ per sticker
Step-by-step explanation:
Given
Total stickers = 75
The cost of 75 stickers = 1.50 (let say in $)
To determine
The unit cost per sticker
The unit cost per sticker can be calculated by dividing the total cost by the number of total stickers, so
Unit cost = 1.50 / 75
= 0.02 $ per sticker
Therefore, the unit cost is: 0.02 $ per sticker

C 50 kilograms
D 500 kilograms
Answer:
50 liters (b)
Step-by-step explanation:
An average water bottle is about 1 liter. 5 liters would be way too less to fill a bathtub! So, 50 liters. Also, we don't measure capacity/volume using kilograms. :p

Answer:
[tex]\theta=54.2^\circ[/tex]
Step-by-step explanation:
Right Triangles
The ratios of the sides of a right triangle are called trigonometric ratios. Each acute angle has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.
The tangent ratio is defined as:
[tex]\displaystyle \tan\theta=\frac{\text{opposite side}}{\text{adjacent side}}[/tex]
The opposite side is 25 and the adjacent side is 18, thus:
[tex]\displaystyle \tan\theta=\frac{25}{18}=1.389[/tex]
The angle is calculated by using the inverse tangent function:
[tex]\theta=\arctan 1.389[/tex]
[tex]\boxed{\theta=54.2^\circ}[/tex]

Answer:
The measure of angle DPA is 39°
Step-by-step explanation:
step 1
Find the value of x we know that arc AB+arc BC+arc CD+arc DA=360°
substitute the values
(5x+10)°+(x+1)°+3x°+(3x+25)°=360°
Solve for x
(12x+36)°=360°
12x=360°-36°
x=324°/12=27°
step 2 Find the measure of angle DPA
we know that The measurement of the external angle is the semi-difference of the arcs which comprises
m∠DPA=(1/2)[arc DA-arc BC]
arc DA=3(27)+25=106°
arc BC=27+1=28°
substitute the values
m∠DPA=(1/2)[106°-28°]=39°
Answer:
BC = 50
Step-by-step explanation:
AB and AD are congruent, thus
AB = AD, that is
5x + 10 = 3x + 18 ( subtract 3x from both sides )
2x + 10 = 18 ( subtract 10 from both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Thus
BC = 12x + 2 = 12(4) + 2 = 48 + 2 = 50

Ryan, Jessica, and Mark each solved this system of equations. All of their answers are different. Find and explain the mistakes. What is the correct answer?
Answer:
Step-by-step explanation:
y = 3x + 2
6x – 2y = 10
Ryan’s answer:
I solved by adding the equations. The solution is .
y = 3x + 2 → 3x + y = 2
6x – 2y = 10 → 3x – y = 5
6x = 7
x =
6x – 2y = 10 → 6 – 2y = 10
7 – 2y = 10
–2y = –3
y = -
Jesse’s answer:
I used matrices. The solution is .
Mark’s answer:
I graphed the equations. The lines are parallel and do not intersect, so there is no solution.

Step-by-step explanation:
To find each output {f(x)}, multiply each input (x) by 3, then add 3 to the product.
Answer:
in order from top to bottom, the answers are -6. -3. 12. 15. and 18
step by step explanation:
to do this you take the equation f(x)=3x+3 and take substitute the number in the x column where it says x.
example: f(x)=3(-3)+3
after that you solve the equation. -3×3 is -9 and then -9+3= -6
