Answer:
X= 2
y = 2
Step-by-step explanation:
y=-2x+6............... equation 1
y=3x-4................... equation 2
from equation 2
y=3x-4
substitute y=3x-4 in equation 1
3x-4=-2x+6
collect like terms
3x+2x=6+4
5x=10
divide both sides by 5
X=2
substitute X=2 in equation 1
y=-2x+6
y=-2(2)+6
y=-4+6
y=2
hope it helps
What is the area of the sector of the circle when the radius is 10 and the shaded part is 45 degrees
Answer:
We are solving for the area so; A=134.16
Step-by-step explanation:
Here is the formula for finding area of a sector:
A = [tex]\pi r^{2}[/tex] × θ° ÷ 360°
where theta is the angle of the sector you wish to find, and r is the radius of the circle.
Substitute the numbers in and you get:
[tex]\frac{25\pi }{2} unit ^{2}[/tex]

Answer:
x2 = -0.600000
x3 = -0.521600
Step-by-step explanation:
Given the formula;
xn+1 = (xn)³-5/10
x2 = (x1)³-5/10
Given x1 = -1
x2 = (-1)³-5/10
x2 = (-1-5)/10
x2 = -6/10
x2 = -0.600000
x3 = (x3)³-5/10
Given x3 = -0.6
x3 = (-0.6)³-5/10
x3 = (-0.216-5)/10
x3 = -5.216/10
x3 = -0.521600

Find the circumference of the circle.
Answer:
11[tex]\pi[/tex]
Step-by-step explanation:
To find the circumference of a circle, the formula is:
d * [tex]\pi[/tex] = c
We already know the diameter, so we just plug that in:
11 * [tex]\pi[/tex] = c
11[tex]\pi[/tex] = c

Create an equation of a line that is parallel to y = 4x – 7
Answer:
There are many..
One would be y = 4x + 7
The trick is the slope is always the same. The only difference is the y-int. You could make one yourself, just use 4x at the beginning.
Please give Brainliest!! Hope this helps!!

Answer:
y = 4x
Step-by-step explanation:
A parallel line will have the same slope. The given line is written in "slope-intercept form", so the slope is readily identified from the equation.
y = mx + b . . . . . line with slope m and y-intercept b
y = 4x -7 . . . . . . line with slope 4 and y-intercept -7
So, the parallel line will be something of the form ...
y = 4x + b
for any value of b. The simplest is to let b=0. If b=-7, then the lines are coincident, not parallel, so that value must be excluded. Any other value of y-intercept will give a parallel line.
y = 4x . . . . . parallel line

A group of college students spent $58.50 for dinner and wanted to leave a 15% tip. Which is the closest to the amount they should leave?
$4
$6
$9
$12
Answer:
9 dollars
Step-by-step explanation:
58.5 times .15 = 8.775 which can be rounded up to 9 dollars
If group of college students spent $58.50 for dinner and wanted to leave a 15% tip. Then $9 is the tip.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
A group of college students spent $58.50 for dinner
The students want to leave a tip of 15%.
We need to find how much they has to leave as tip.
Firstly we have to convert 15% to decimal.
We have to divide 15 by 100
15/100
0.15
Now we have to multiply 0.15 with 58.50 to find the 15% of 58.50
0.15×58.50
8.775
9
Hence, $9 is the tip the students has to leave.

Mikayla subtracted 4 from both sides in the beginning when she should've added it to both sides to cancel it out on the right. the correct answer should actually be x=1
Answer:
Mikayla subracted 4 from both sides, not add. She was supposed to add so that the -4 can cancel out.
The correct answer would be x=1
