Answer:

375-17=358

Step-by-step explanation:

Answer:

The equations are not compatible

Step-by-step explanation:

y = -4x + 3

8x + 2y = 8

substitute for y:

8x + 2(-4x + 3) = 8

simplify:

8x - 8x + 6 = 8

6 ≠ 8

Answer:

The slope of the line that intersects the points (13, -4) and (1, 12) is 4/-3.

Step-by-step explanation:

The equation [tex]m=\frac{y2-x2}{y1-x1}[/tex] is used to solve for slope [tex]m[/tex].

[tex]m=\frac{12-(-4)}{1-13}=\frac{12+4}{-12} =\frac{16}{-12} =\frac{4}{-3}[/tex]

If you need it in decimal form, then 4/-3=-1.33333333333

Answer:

4

Step-by-step explanation:

You set f(x) = 9 and solve from there.

9 = 4x - 7

+7         +7

16 = 4x

/4     /4

x = 4

Answer:

The answer is 4

Step-by-step explanation:

f(x)=4x-7

f(x)=9

9=4x-7

9+7=4x-7+7

(the -7 and the +7 cancel out, and remember: whatever you do the one side you have to do to the other)

16=4x

(divide by 4 to isolate x and do the same to the other side of the equation so you get the answer)

so, x=4

Answer:

He has $7.75 left.

Step-by-step explanation:

To solve this problem you must subtract $25.50 by $17.75 because he bought the pen for 17.75 which is being taken away from his amount of money to start with ($25.50).

Step by step solving the subtraction problem:

$25.50-$17.50 = $7.75

So 25.50 - 17.75 you would need to make the 0 become a ten and then subtract 10 and 5, then you bring down the 5 from ($25.50) and make it 14 and subract 14 and 7. Then bring down the other 5 and make it 14 as well and subract 14 by 7 which is 7. Finally make the 2 a 1 and it will end up being 1-1 which is zero. So the answer will end up being $7.75. Hope that helps. Sorry that this answer took long for it to be posted.

Answer:

x+y=−3

Step-by-step explanation:

hope this heps:)

Answer:

x+y=-3 (put -3 into the box)

Step-by-step explanation:

add x to both sides, and you get x+y= -3.

Step-by-step explanation:

Answer:

6³ because 2³ and 3³ can be multiplied because they are to the same power, and keep the same power. Also, 6³ is 216.

Answer:

We have to use the formule to calculate the vertex which is: V(-b/2a;4ac-b^2/4a)

A) y=x+7 where a=1 b=0 and c=7

By replacing we have: V(0;28/4) V(0;7)

B) y=-x where a=-1 b and c=0 so V(0,0)

Answer:

P = 30 degrees, PQ = 6.93, PN = 8

Step-by-step explanation:

For the angle, just subtract the angles you already know from 180, so 180 - 90 - 60= P. P = 30 degrees.

For PQ, use tan60 = x/4, or 4tan(60), which equals 6.93.

For PN, use cos60 = 4/x, or 4/cos60, which equals 8.

Hopefully this helps- let me know if you have any questions!

Answer:

a) 94.2 cm

b) 78.5%

Step-by-step explanation:

a) since the square side = 30 cm

it means the diameter = 30 cm

then circumference of the largest circle that can be cut = 3.14×30 = 94.2 cm

b) the perimeter of the square = 30×4 = 120

94.2 for 120

x% for 100%

x = (100×94.2)/120 = 9420/120 = 942/12 = 78.5%

Answer:

it’s probably option 1 and the other person explained so yeah

Answer:

height= 30 area= 2160

Step-by-step explanation:

I don't think this is even right, but since a triangle adds up to 180, subtract the 72 and both 39's from 180. that should give you 30, the missing number (the height)

Then, to find area the formula is a=b*h

You already have the base in the image and you already calculated the height

Again, I don't know if this is right. It's not the same as how I do it here

Answer:

h = 15, A = 540

Step-by-step explanation:

Since the 2 legs are congruent then h is a perpendicular bisector, dividing the triangle into 2 right triangles.

Using Pythagoras' identity on one of the right triangles

with leg 72 ÷ 2 = 36 and hypotenuse = 39

h² + 36² = 39²

h² + 1296 = 1521 ( subtract 1296 from both sides )

h² = 225 ( take square root of both sides )

h = [tex]\sqrt{225}[/tex] = 15

Then

A = [tex]\frac{1}{2}[/tex] × 72 × 15 = 36 × 15 = 540 mi²

Answer:

4th option

Step-by-step explanation:

An inequality using > or < has a broken boundary when graphed.

An inequality using ≥ or ≤ has a solid boundary when graphed

Then y ≥ 9x + 9 has a solid boundary

Answer:

7.2

Step-by-step explanation:

to find the diameter you always times it by 2

whilst to find the radius you do diameter ÷ 2

so if you times 3.6 x 2 = 7.2

also, you can't round 7.2 to the nearest tenth because it's already in that form

Answer:

Step-by-step explanation:

a radius is the length of a line segment from the center of a circle to the edge of the circle

a diameter is the length of a line segment from both edges of a circle and passing through the center of a circle

the line segment in the diagram looks like a radius (assuming the black dot represents the center of the circle)

if you left the line segment where it is and then rotate another the line segment in the diagram around so that is straight in line with the original line segment you would see that you just created a diameter

the diameter is twice as long as one radius

a diameter = 2 times a radius         d = 2r        d = diameter  r = radius

so d = 2 x 3.6           use your own calculator to solve

Answer:

67.50

Step-by-step explanation:

Answer:

The hundredth is always the second number after the decimal point (to the right).

So, when rounding to that number look at the number on the right of it, which in this case is 9.

Then, if the number is 5 to 9, round up, but if it is 0 to 4, round down.

In this case, the number above 0.49 is 0.5.
