Answer:

(5, 9)

Step-by-step explanation:

Given:

The equations to solve are:

$x=5\\y=2x-1$

Since the value of 'x' is given, we solve this system of equations using Substitution method.

We have to solve this by substituting in the value of 'x' from first equation into second equation.

Therefore, the second equation becomes

$y=2(5)-1\\\\y=10-1\\\\y=9$

Therefore, the values are: $x=5, y=9$

Hence, the solution is in ordered pair form is (5, 9).

If the triangle are similar, write a similarity

Vesna [10]

Answer:

The triangles are similar due to AAA

Step-by-step explanation:

'The triangles ABC and DBE are similar because they have a common angle < B, and also angle < E is marked as congruent to angle < A. Then the third angle <C is going to be congruent to angle D as well due to the property of addition of internal angles of a triangle must add to 180 degrees.

Then the triangles are similar due to AAA

Given the parent function

lozanna [386]

Answer:

Option c is right.

Step-by-step explanation:

Given is a parabola y =x^2

From that transformation is done to get parabola as

y =(0.2x)^2

We find that instead of x here we use 0.2x

i.e. New x = 5 times old x

Hence there is a horizontal expansion of scale factor 5.

We can check with any point also

When y =4, x=2 in the parent graph

But when y =4 , we have x = 10 in the new graph

i.e. there is a horizontal expansion of scale factor 5.

You are given: Students must take at least 2 courses out of Art, History, and Science. 60% of the students take Art. 80% of the

Eva8 [605]

Answer:

0.10 or 10%

Step-by-step explanation:

Since each student must take at least 2 courses, if no student took all three courses, the sum of the percentages would total 200% (counting each student twice). Therefore, the proportion of students taking all three courses is the difference between the sum of all percentages and 200%:

$P(3) = 60\%+80\%+70\%-200\%\\P(3) = 10\%$

0.10 or 10% of the students take all 3 courses.
