A. all real numbers for both

Explanation:
Domain is the x-values. Since the graph goes forever horizontally, any x-value is on the graph.
Range is the same but with y-values. If the graph went on further than what the picture shows, then it also would show that every y value is on the graph

Put the equation in standard form y=-4/5x+2
sp2606 [1]

Answer:

4x +5y = 10

Step-by-step explanation:

Standard form of an equation is Ax +By = C

y=-4/5x+2

Add 4/5 x to each side

4/5 x +y=-4/5x+ 4/5x+2

4/5 x + y = 2

Now we don't have fractions in A ,B  or C

So Multiply by 5

5(4/5 x + y) = 2*5

Distribute

4x +5y = 10

How can you change the dimensions of the rectangle so that the ratio of the length to the width stays the same, but the perimete
Lady bird [3.3K]

Answer:

L = 62.5cm; B = 30cm

Step-by-step explanation:

P = 2 (L+W): L=25cm; W=12cm

=2 (25+12)

=50+24

P = 74cm

For a congruent rectangle with P = 185cm

A: 74 = 2 (25 + 12)

B: 185 = 2( ? + ?)

Since A/B are congruent;

185/75 = 2.5

B = 2 (2.5* (25 + 12)

= 2 ( 62.5 + 30)

= 125 + 60

= 185

Hence, B: L = 62.5cm; B = 30cm

185cm = 2 (62.5 + 30)
