Answer:

x intercept = (5, 0)

y intercept = (0, -2)

slope = 2/5

Step-by-step explanation:

2x - 10 = 5y

$\frac{2x-10}{5}$ = y

$\frac{2}{5}$ x -2 = y

The quadratic equation ax^2+32x+c=0 has exactly one solution. If a+c=130, and a>c, find the ordered pair (a,c).

vitfil [10]

Ie 32^2 - 4ac=0 so ac=256 and a+c=130
So, that means:2 equations ac=256 a+c=130 ie c=130-a
So,a(130-a)=256 so 130a -a^2=256 ie a^2-130a +256=0 (a-2)(a-128)=0
Finally,giving a= 2 or a=128 so, a=2 c=128 or a=128 c=2
Since, a>c , a=128 and c=2 ie (128,2)

3<br> Find the value of x.<br> 34°<br> o<br> 27°

lana [24]

Hi there! :)

$\large\boxed{x = 122^{o}}$

Recall that the sum of all angles in a triangle = 180°.

Therefore:

34° + 24° + x° = 180°

Combine like terms and subtract:

58° + x° = 180°

x = 180° - 58°

x = 122°

4 11/16÷1 1/4<br> answers:<br> 2 1/8<br> 2 1/4<br> 3 7/16<br> 3 3/4

SashulF [63]

Answer:

$\displaystyle3\frac{3}{4}$

Step-by-step explanation:

Hi there!

$4\displaystyle\frac{11}{16} \div1\frac{1}{4}$

Change mixed numbers to improper fractions:

$= \displaystyle\frac{75}{16} \div\frac{5}{4}$

Dividing by a fraction is the same as multiplying by its reciprocal:

$= \displaystyle\frac{75}{16} *\frac{4}{5}$

Reduce:

$= \displaystyle\frac{75}{4} *\frac{1}{5}$

$= \displaystyle\frac{15}{4} *\frac{1}{1}$

$= \displaystyle\frac{15}{4}$

Change improper fraction into mixed number:

$= \displaystyle3\frac{3}{4}$

I hope this helps!

Triangle FCD is cut from parallelogram ABCD moved with left-hand side. What are the dimensions of the resulting triangle AEFD?

Ilya [14]

Answer:

The answer is below

Step-by-step explanation:

Triangle FCD is cut from parallelogram ABCD moved with left-hand side. What are the dimensions of the resulting rectangle AEFD?

A parallelogram is a quadrilateral (has four sides and four angles) in which opposite sides are parallel to each other.

A rectangle is a quadrilateral with opposite sides which are parallel and equal to each other. All the angles in a rectangle are at 90 degrees.

From the image, AD = z, FC = x, BF = w and BC = y. Hence:

EB = FC = x.

EF = AD = length = z; AE = FD = height = w

Therefore the dimensions of rectangle AEFD is length z and height w
