IXL 7th grade math could someone please help!

KIM [24]

Answer:

supplementary angles are two angles that when add equal 180 degrees.

The supplement of an angle is 180 - n.

Step-by-step explanation:

n = 17(180 - n)

n = 3060 - 17n

n + 17n = 3060

18n = 3060

n = 3060/18

n = 170

so the unknown angle (n) = 170 degrees and its supplement = (180 - 170 = 10)......= 10 degrees.

A line passes through (5,-2) with a slope of 1/4. Write the equation in slope-intercept form.

trapecia [35]

Answer: y = $\frac{1}{4}$ x - 3 $\frac{1}{4}$

Step-by-step explanation:

Slope-intercept form is in the form of y=mx + b where m is the slope and b is the y-intercept.

We are given the slope, so we will plug this in.

y = mx + b

y = ( $\frac{1}{4}$ )x + b

Now, we will solve for the y-intercept by plugging in the point they give us.

y = ( $\frac{1}{4}$ )x + b

(-2) = ( $\frac{1}{4}$ )(5) + b

-2 = 1.25 + b

-3 $\frac{1}{4}$ = b

Lastly, we will plug this variable into the equation we wrote above for our final answer.

y = $\frac{1}{4}$ x - 3 $\frac{1}{4}$

I need help with this, it's due in 15 mins-

LiRa [457]

Answer:

Mean: 3.5263157894737

Median: 3

Mode: 3

Step-by-step explanation: The mode is 3 because the mode is for which number pops up the most, which is 3.

I got the median by crossing out 8 from the left and the right of the number set and got 3 as the last number.

I got the mean by adding up all the numbers and divided it by the amount of numbers in the set.

The ratio of sweaters to dresses that Jennifer has is 8:5. If

melomori [17]

Answer:

Ratio of sweaters to dresses = 8 : 5

Sum of ratios = 13

Let number of sweater + dresses = x

$number \ of \ sweaters = \frac{8}{13} *x\\\\24 = \frac{8}{13}*x\\\\x = \frac{24*13}{8} = 3*13 = 39$

$number \ of \ dresses = 39 - 24 = 15$

Consider the equation below.

Korvikt [17]

Answer:

Equation in square form:

$y=3(x+5)^2-4$

Extreme value:

$(h,k)=(-5,-4)$

Step-by-step explanation:

We are given

$y=3x^2+30x+71$

we can complete square

$y=3(x^2+10x)+71$

we can use formula

$a^2+2ab+b^2=(a+b)^2$

$y=3(x^2+2\times x\times 5)+71$

now, we can add and subtract 5^2

$y=3(x^2+2\times x\times 5+5^2-5^2)+71$

$y=3(x^2+2\times x\times 5+5^2)-3\times 5^2+71$

$y=3(x+5)^2-75+71$

So, we get equation as

$y=3(x+5)^2-4$

Extreme values:

we know that this parabola

and vertex of parabola always at extreme values

so, we can compare it with

$y=a(x-h)^2+k$

where

vertex=(h,k)

now, we can compare and find h and k

$y=3(x+5)^2-4$

we get

h=-5

k=-4

so, extreme value of this equation is

$(h,k)=(-5,-4)$
