Find the equation of a line perpendicular to y - 3x = – 8 that passes through the point (3, 2). (answer in slope-intercept form)

Answer:

x = 2

Step-by-step explanation:

-5(x + 2) = -20

-5x - 10 = -20

-5x = -20 + 10

-5x = -10

x = -10/-5

x = 2

Answer:

Step-by-step explanation:

-5(x+2)=-20

-5x -10=-20

-5x=-10

x=2

Answer:

Pls try to see if I get the correct answer

Answer:

(3,2)

Step-by-step explanation:

Here's your given:

y = 4x - 10

y = 2

Because they both equal y, that means they equal each other:

2 = 4x - 10

Add 10 on both sides:

12 = 4x

Then, divide 4 on both sides:

3 = x

This represents the x coordinate.

Normally you would put this value into one of the equations to figure out y, but they already gave us that in the beginning:

y = 2

This represents the y coordinate.

Put the two values together to get: (3,2)

Answer:3/5, 6/10, 9/15

Answer:

Human activities such as driving cars, and working at factories contribute to global warming significantly because burning fossil fuels in cars releases carbon dioxide, which is the largest source of greenhouse gas emissions in the U.S. and as these gases build up, they trap heat in the atmosphere, causing climate change.

Let r represent cost of each box.

We have been given that Mia bought 10 boxes of brownies. So cost of 10 boxes would be [tex]10r[/tex].

We have been given that Mia bought 10 boxes of brownies at the store for a total of $64. The tax on the purchase was $5. So the total cost of 10 boxes would be cost of 10 boxes plus tax.

We can represent this information in an equation as:

[tex]10r=64+5[/tex]

We can subtract 64 from both sides as:

[tex]10r-64=64-64+5[/tex]

[tex]10r-64=5[/tex]

Therefore, our required equation is [tex]10r-64=5[/tex] and option 'c' is the correct choice.

Hi there!

[tex]x + 50.75\geq \frac{387}{4} \\\\x\geq \frac{387}{4} -50.75\\subtract \\x\geq \frac{387}{4} - \frac{203}{4} \\solution:\\x\geq 46\\\\\\[/tex]

The answer is: C

Answer:

Yes your answer is c

Step-by-step explanation:

First convert to mixed fraction.

X + 50.75 > 387 / 4

Then subtract 50.75 from both sides

X + 50.75 - 50.75 > 387 / 4 - 50.75

Finally simplify,

X > 46

(I couldn't do the dash under the greater than sign)

Hope this helps have a good day! :).

Answer:

The point N lies inside the circle

Step-by-step explanation:

A circle is centered at the point T(-6,3) and has a radius of r=1.

To determine if the point N(3,-3) is inside or outside the circle, the distance between N and the point T must be lower than 11.

To calculate the distance between points T and N you use:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

where x1 and y1 are the coordinates of T, and x2 and y2 the coordinates of N.

[tex]d=\sqrt{(3-(-6))^2+(-3-3)^2}=\sqrt{9^2+6^2}=10.81[/tex]

d < 11

The distance d is lower than the radius of the circle. Hence, the point N lies inside the circle

Answer:

64°

Step-by-step explanation:

Both triangles represent a right angle by the small box in the angle.

Right angles = 90°

Since the triangles are congruent, then they would have the same measurements in their angles an sides. All triangles also have a sum of 180°. So, we can just subtract (26 + 90) from 180 to get the third angle.

180 - (26 + 90)

180 - 116

64

So, the m∠KLM is 64°.

Answer:

Step-by-step explanation:

Answer:

-8/3 or -2 2/3

Step-by-step explanation:

-5 1/3 + 2 2/3 can be made into the improper fractions -16/3 + 8/3 if you multiply the whole number and the denominator together then add the numerator, so now you do the math:

-16 + 8 = -8

3 stays as the denominator leaving you with -8/3, or -2 2/3

Answer:

x=4 or x=-10

Step-by-step explanation:

x² + 6x = 40

x² + 6x - 40 = 40 - 40

x² + 6x - 40 = 0

Use quadratic formula:[tex]\frac{b-+\sqrt{b^{2} -4ac} }{2a}[/tex]

a=1 , b=6 , c= -40

[tex]\frac{-(6)-+\sqrt{6^{2} -4.1.(-40)} }{2.1}[/tex]

Answer:

d = -29

Step-by-step explanation:

-(1/8)d -4 = -(3/8)

Multiply everything by 8 to get rid of the fractions

8*-(1/8)d -4*8 = -(3/8)*8

-d -32 = -3

Add 32 to each side

-d+32 -32 = -3+32

-d = 29

Multiply everything by -1

d = -29

Answer:

The square root of a positive number cannot be negative.   False.  There are two square roots, one positive and one negative.

All positive numbers have two square roots.   True.  See above.

Answer:

Mae Ling earns a weekly salary of $335.

She also earns 5.0% commission on sales. If she sold 4200 worth of merchandise, she would get 4200 x 5/100 = 210$

Totally, she earns 335 + 210 = 545$

Hope this helps!

:)

Answer:

$545

Step-by-step explanation:

Commission is basically the percentage of the profit made that the salesperson gets to keep. The weekly salary is a fixed amount, so that won't change.

Here, Mae Ling sells $4200 worth of merch, which is the profit made, so the commission will be 5% of that:

5% * 4200

Remember that % is just "out of 100", so 5% = 5/100:

(5/100) * 4200 = $210

Add this to the salary:

335 + 210 = $545

She would make $545.

Answer:

The area of the wall on the blueprint is 0.1764 ft²

Step-by-step explanation:

The scale is the relationship that exists between the magnitudes of a drawing and the actual dimensions.

The scale factor is the ratio of the dimensions in two similar figures. The term "similar figures" refers to figures that have the same shape but different sizes.

 The ratio between areas is equal to the squared scale factor. This is,  the scale factor for areas is the squared scale factor,

To solve scale problems in this case, then the following proportion must be proposed:

[tex]\frac{representation area}{actual area} =scale factor^{2}[/tex]

Being:

Replacing:

[tex]\frac{representation area}{36 ft^{2} } =0.07^{2}[/tex]

Solving:

representation area= 0.07²*36 ft²

representation area=0.1764 ft²

The area of the wall on the blueprint is 0.1764 ft²
