Answer:
x=45/6
Step-by-step explanation:
2+7y=8. 7y=8-2. <u>7</u><u>y</u><u>=</u><u>6</u>
7=7. y=6\7
insert the value of y in the second equation. 5x-7y=16
5x-7(6/7)=16
5x-49\6=16
collect the liketerms together
5x=16+49/6
5x=145/6(divide both sides by 5)
x=29/6
x=45/6
<em><u>f</u></em><em><u>u</u></em><em><u>r</u></em><em><u>t</u></em><em><u>h</u></em><em><u>e</u></em><em><u>r</u></em><em><u>.</u></em>
<em><u> </u></em>confirm if the 2 in the second equation has an X coz the questions are normally set with both equations having both values x and y
Answer:
less than 16
Step-by-step explanation:
Answer:
4/4
Step-by-step explanation:
2/3 * what = 8/12
Multiply the top and bottom by 4/4
2/3 *4/4 = 8/12
P(x₁ , y₁) and Q(x₂ , y₂) ↔ [ P(0,14) Q(5, - 2)]
Distance = PQ = √[(x₂ - x₁)² + (y₂ - y₁))²]
PQ = √[(5 - 0)² + (- 2 - 14)²]
PQ = √[(25 + 256]
PQ = √281
PQ = 17.76
