Answer 1

Answer:

C

Step-by-step explanation:

21 - (-5)     A negative minus a negitive turns into a +

21 + 5 = 26

A.  -21 + 5 = -16      NO

B.    21 - 5 = 16   NO

C. 21 + 5 = 26    YES

D. -21 - 5 = -26    NO

Answer 2

Answer:

C

Step-by-step explanation:

When subtracting a negative, the two negatives cancel out. The rule is that two like signs become positive.

Therefore, +(+) =+ and -(-) = +  

So, the equation would be 21 + 5.

What is the minimum angle of rotation lin degrees that will carry the six-sided star onto itself?
What’s the degree

Answers

Answer:

120 degrees

Step-by-step explanation:

If it's a 6 sided star, that means that it will be divided into 3 parts (think about how a normal 5-point star has 10 sides). That means that we divide 360 (total number of degrees in a full rotation) by 3 (number of sections) = 120

The negative sign can be read as "the opposite of."

Aline crosses the coordinates (-4,4) and (2.-5). What is the slope
of the line?

Answers

Answer:

Step-by-step explanation:

Use the slope formula:

[tex]m = \frac{y2 -y1}{x2 - x1}[/tex]

where m = slope

Given the coordinates

(-4, 4) ---> this means x1 = -4 , y1 = 4

(2, -5) ---> this means x2 = 2 , y2 = -5

Substitute these values into the slope formula:

[tex]m = \frac{y2 -y1}{x2 - x1}[/tex]

[tex]m = \frac{-5 -4}{2 - (-4)} = \frac{-9}{2+4} = \frac{-9}{6} = \frac{-3}{2}[/tex]

The slope of the line passing through the coordinates (-4, 4) and (2, -5) is - 3/2.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

The slope of the line passing coordinates (-4, 4) and (2, -5) can be obtained as we know slope is rise over run which is slope(m) = (y₂ - y₁)/(x₂ - x₁) = (-5 - 4)/(2 + 4) = -9/6 = - 3/2.

Its Not The Answer But Its Your Question Simplified

Answer:

I don't know if this is correct but it probably is but I got x=5

Step-by-step explanation:

you write the equation and put the line through the sign, and cross out the 3. Then you are going to add 3 to the seven which will then equal 2x > 10. Then you cross out the 2 and divide both side with the 2. and 10 divided by 2 is 5 so therefore x equals 5.

Solve for x using the

7(x + 3) = -49

Answers

Answer:

x= -10

Step-by-step explanation:

distribute 7 to x and 3: 7x + 21 = -49

subtract 21 from both sides to isolate the variable: 7x= -70

divide both sides by 7 to find x: x= -10

Answer:

X = -10

Step-by-step explanation:

1.- 7x + 21 = -49

Subtract 21 on both sides of the equal sign

You should have:

2.- 7x = -70

Divide 7 on both sides of the equal sign

You should get the answer:

X = -10

x = 94°

Step-by-step explanation:

interior angle sum of any polygon: (s-2)×180°

with s being the number of sides.

since there are 7 sides, 7-2 = 5

5* 180°

900° = total sum

______________________________

since we know the rest of the angles, just subtract the total sum from the sum of the known angles to find the unknown one.

900°-(148°+140°+136°+142°+150°+90°) = x

900°- 806°= 94°

x= 94°
