Answer:

109

Step-by-step explanation:

every straight line equals 180 so the sum of the angles should add up to 180

180-71= 109

side note- interior angles add up to 180

Answer:

Sales tax = $2.79

Step-by-step explanation:

(18 x 48.6) /100

= 8.748 = $8.75 tip amount total

48.60-8.748 = 39.852 sales total

(39.852 x 7)/100

= 2.78964 = $2.79 sales tax

39.852 - 2.78964 = 37.06236 = $37.06 cost of bill

Sales tax was asked = $2.79

Answer:

  4.  D'(5, -5), E'(2, -7), F'(6, -1), G'(10, -8)

  5.  T(-3, 2)

Step-by-step explanation:

4. Translation by 4 units right and 5 units down adds (4, -5) to each given coordinate point. (We note that these coordinates do not actually form a parallelogram.) The figure and its translation are attached.

__

5. The translation is ...

  X' -X = (-8, -1) -(-5, -3) = (-8+5, -1+3) = (-3, 2)

The translation is left 3, up 2. We don't know the translation notation you're used to, so we'll write it as ...

  T(-3, 2) . . . . . translation left 3, up 2.

theres ur answer above me

Step-by-step explanation:

The restriction is that x ≠ -4 is not in the domain of the given function.

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

The given function is

[tex]f(x)=\frac{x-1}{x+4}[/tex]

This is not defined when the denominator is zero.

Hence the restriction is on the denominator.

This implies that

[tex]x+4 \neq 0[/tex]

[tex]x\neq-4[/tex]

The restriction is that x ≠ -4 is not in the domain of the given function.

Answer:

[tex]\frac{3}{4} =\frac{18}{24}[/tex] The ratios are the same .

Step-by-step explanation:

When  y ∝ x then,

[tex]y=k*x[/tex]

When y ∝ 1/x then

[tex]y=\frac{k}{x}[/tex]

while k is a constant.

Answer:

3/4 and 18/24; the ratios are the same.

Step-by-step explanation:

A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "three is to four as eighteen is to twenty-four."

In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

Here, 3 and 24 are the extremes, and 4 and 18 are the means. Since the cross products are both equal to 60, we know that these ratios are equal and that this is a true proportion.

Answer:

I think y=1x+2

Step-by-step explanation:

y=mx+c

m=(y2-y1)/(x2-1)

I just chose (0,2) and (-3,-1)

-1-2=-3

-3-0=-3

-3/-3=1

y=1x+c

c= y-intercept and (0,2) is the y-intercept so

y=1x+2

Answer:

x = 5

Step-by-step explanation:

-4x + 2 = -18

subtract 2 from both sides

-4x + 2 - 2 = -18 - 2

simplify

-4x = -20

divide both sides by -4

-4x/-4 = -20/-4

simplify

x = 5

Answer:

for a it would be 11/18 and for b it would be 4/9

Step-by-step explanation:

This is because I did the same butterfly method. 5 times 5 times 18 which is 90 for 5/9 and 9 times 18 is 99 for 11/18, you can also write it as 5/9 and 11/18 but cross multiply. This is also what I did with the second one.
