Answer:
w = -9
Step-by-step explanation:
7/3w + 19 = -2
-19 -19
7/3w = -21
Divide both sides by 7/3
w = -9

Step-by-step explanation:
A piece of cardboard has the dimensions (x + 15) inches by (x) inches with the area of 60 in 2 . Write the quadratic equation that represents this and show your work. Then find the possible value(s) for x, and find the actual dimensions of the postcard.
Answer:
[tex]x^2 + 15x - 60 = 0[/tex]
The actual dimension is 18.28 by 3.28
Step-by-step explanation:
Given
Dimension:
[tex](x + 15)\ by\ x[/tex]
[tex]Area = 60in^2[/tex]
Required
Determine the quadratic equation and get the possible values of x
Solving (a): Quadratic Equation.
The cardboard is rectangular in shape.
Hence, Area is calculated as thus:
[tex]Area = Length * Width[/tex]
[tex]60= (x + 15) * x[/tex]
Open Bracket
[tex]60= x^2 + 15x[/tex]
Subtract 60 from both sides
[tex]x^2 + 15x - 60 = 0[/tex]
Hence, the above represents the quadratic equation
Solving (b): The actual dimension
First, we need to solve for x
This can be solved using quadratic formula:
[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
Where
[tex]a = 1[/tex]
[tex]b = 15[/tex]
[tex]c = -60[/tex]
So:
[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]
[tex]x = \frac{-15 \± \sqrt{15^2 - 4*1*-60}}{2*1}[/tex]
[tex]x = \frac{-15 \± \sqrt{225 + 240}}{2}[/tex]
[tex]x = \frac{-15 \± \sqrt{465}}{2}[/tex]
[tex]x = \frac{-15 \± \21.56}{2}[/tex]
Split:
[tex]x = \frac{-15 + 21.56}{2}[/tex] or [tex]x = \frac{-15 - 21.56}{2}[/tex]
[tex]x = \frac{6.56}{2}[/tex] or [tex]x = \frac{-36.36}{2}[/tex]
[tex]x = 3.28[/tex] or [tex]x = -18.18[/tex]
But length can't be negative;
So:
[tex]x = 3.28[/tex]
The actual dimensions: [tex](x + 15)\ by\ x[/tex] is
[tex]Length =3.28 +15[/tex]
[tex]Length =18.28[/tex]
[tex]Width = x[/tex]
[tex]Width =3.28[/tex]
The actual dimension is 18.28 by 3.28
Identify the equation of the line graphed below.
Answer:
B
Step-by-step explanation:
this is the correct awnser because the thingy is y-y¹=slope(x-x¹) so for y¹ it would be 2 and that gives away the awnser. because all of the other ones have different numbers if the minus sign is an addition sign it mean that the y¹ is negative which it isnt.
how you would find the y¹ is you look on the y-axis and see where the line goes through perfectly which is the positive 2
Hope this helps!
and isn't to complicated
Use the distributive property to write the following expressions in expanded form. e ( f + g )
Answer:
ef + eg
Step-by-step explanation:
Distributive Property: a(b +c) = (a*b) + (a*c)
e(f +g) = e*f + e*g
= ef + eg

The Side-Splitter Theorem states that:
JKP is any triangle
KL is drawn parallel to MN, then JK/KM = JL/LN
JK/KM = JL/LN = KL/MN
9/13.5 = (37.5 - x)/x = 7.5/y
9/13.5 = 7.5/y
y = 11.249
9/13.5 = (37.5 - x)/x
x = 22.5

The equation that represents the canned goods order is
24x + 64y = 384, where x = number of minutes for
producing fruit cans and y = number of minutes for
producing vegetable cans.
What is the meaning of the y-intercept?
If you can give sample response from edge I will give brainliest!
Answer:
The y intercept is where the number of minutes producing fruit cans is 0 and the value of the number of minutes for producing vegetable cans is on the y-axis.
Step-by-step explanation:
A y-intercept is where the x value is 0 and the y-value is on the y-axis. So, the answer consists of making the x value 0.
Answer:
Sample Answer: The x-intercept, at the point (16, 0) indicates the choice to produce fruit for 16 minutes. In 16 minutes, producing 24 cans of fruit a minute, all 384 cans for the order will be completed. The zero for the y-value represents that no time is spent producing cans of vegetables.

There was 4/5 of a cake sitting on the counter. Daryl ate 1/3 of the left over cake. How much cake was left over after he ate?
Answer:
7/15
Step-by-step explanation:
find a common demonator for example 15
you would do 4x3 for 12 and 5x3 for 15 so your first fraction would be 12/15
for the second fraction you will do 1x5 and 3x5 so your fraction would be 5/15
then you just subtract.
Answer:
7/15
Step-by-step explanation:
4/5 - 1/3. Change the denominators to 15, do they same to the numerators which is multiply by 5. You then have 12 minus 5 = 7. So 7/15.

WHAT'S THE RANGEE??
Answer:
-2 < y ≤ 10
Step-by-step explanation:
The graph's lowest point is at y = -2, and the graph's highest point is at y = 10, so we know it would start off with -2 and end with 10. The dot at the lowest point is not shaded in, indicating that the graph does not include -2. So, we would represent this exclusion in our inequality with a less than (<) sign. As for the highest point at y = 10, it is shaded in, indicating that the graph does include 10. We would show this in our inequality with a less than or equal to sign (≤)

Write \sqrt{-40}
−40
in simplest radical form.
Answer:
2*{2*i*√(10) - 20}
Step-by-step explanation:
i will interpret your expression as being
sqrt{-40} − 40. The first term factors to
sqrt{-4*10)
and the second stays as is.
Then we have
sqrt(-4*10) - 40, or
i*2*sqrt(10) - 40, or
2*{2*i*sqrt(10) - 20}, or
2*{2*i*√(10) - 20}
